6 * Version 3.3.5 (released 2014-06-26)
8 ** libgnutls: Added gnutls_record_recv_packet() and gnutls_packet_deinit().
9 These functions provide a variant of gnutls_record_recv() that avoids
10 the final memcpy of data.
12 ** libgnutls: gnutls_x509_crl_iter_crt_serial() was added as a
13 faster variant of gnutls_x509_crl_get_crt_serial() when coping with
14 very large structures.
16 ** libgnutls: When the decoding of a printable DN element fails, then treat
17 it as unknown and print its hex value rather than failing. That works around
18 an issue in a TURKTRST root certificate which improperly encodes the
19 X520countryName element.
21 ** libgnutls: gnutls_x509_trust_list_add_trust_file() will return the number
22 of certificates present in a PKCS #11 token when loading it.
24 ** libgnutls: Allow the post client hello callback to put the handshake on
25 hold, by returning GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPTED.
27 ** certtool: option --to-p12 will now consider --load-ca-certificate
29 ** certtol: Added option to specify the PKCS #12 friendly name on command
32 ** p11tool: Allow marking a certificate copied to a token as a CA.
34 ** API and ABI modifications:
35 GNUTLS_PKCS11_OBJ_FLAG_MARK_CA: Added
36 gnutls_x509_crl_iter_deinit: Added
37 gnutls_x509_crl_iter_crt_serial: Added
38 gnutls_record_recv_packet: Added
39 gnutls_packet_deinit: Added
40 gnutls_packet_get: Added
43 * Version 3.3.4 (released 2014-05-31)
45 ** libgnutls: Updated Andy Polyakov's assembly code. That prevents a
46 crash on certain CPUs.
48 ** API and ABI modifications:
49 No changes since last version.
52 * Version 3.3.3 (released 2014-05-30)
54 ** libgnutls: Eliminated memory corruption issue in Server Hello parsing.
55 Issue reported by Joonas Kuorilehto of Codenomicon.
57 ** libgnutls: gnutls_global_set_mutex() was modified to operate with the
58 new initialization process.
60 ** libgnutls: Increased the maximum certificate size buffer
61 in the PKCS #11 subsystem.
63 ** libgnutls: Check the return code of getpwuid_r() instead of relying
64 on the result value. That avoids issue in certain systems, when using
65 tofu authentication and the home path cannot be determined. Issue reported
68 ** libgnutls-dane: Improved dane_verify_session_crt(), which now attempts to
69 create a full chain. This addresses points from https://savannah.gnu.org/support/index.php?108552
71 ** gnutls-cli: --dane will only check the end certificate if PKIX validation
74 ** gnutls-cli: --benchmark-soft-ciphers has been removed. That option cannot
75 be emulated with the implicit initialization of gnutls.
77 ** certtool: Allow multiple organizations and organizational unit names to
78 be specified in a template.
80 ** certtool: Warn when invalid configuration options are set to a template.
82 ** ocsptool: Include path in ocsp request. This resolves #108582
83 (https://savannah.gnu.org/support/?108582), reported by Matt McCutchen.
85 ** API and ABI modifications:
86 gnutls_credentials_get: Added
89 * Version 3.3.2 (released 2014-05-06)
91 ** libgnutls: Added the 'very weak' certificate verification profile
92 that corresponds to 64-bit security level.
94 ** libgnutls: Corrected file descriptor leak on random generator
97 ** libgnutls: Corrected file descriptor leak on PSK password file
98 reading. Issue identified using the Codenomicon TLS test suite.
100 ** libgnutls: Avoid deinitialization if initialization has failed.
102 ** libgnutls: null-terminate othername alternative names.
104 ** libgnutls: gnutls_x509_trust_list_get_issuer() will operate correctly
105 on a PKCS #11 trust list.
107 ** libgnutls: Several small bug fixes identified using valgrind and
108 the Codenomicon TLS test suite.
110 ** libgnutls-dane: Accept a certificate using DANE if there is at least one
111 entry that matches the certificate. Patch by simon [at] arlott.org.
113 ** libgnutls-guile: Fixed compilation issue.
115 ** certtool: Allow exporting a CRL on DER format.
117 ** certtool: The ECDSA keys generated by default use the SECP256R1 curve
118 which is supported more widely than the previously used SECP224R1.
120 ** API and ABI modifications:
121 GNUTLS_PROFILE_VERY_WEAK: Added
124 * Version 3.3.1 (released 2014-04-19)
126 ** libgnutls: Enforce more strict checks to heartbeat messages
127 concerning padding and payload. Suggested by Peter Dettman.
129 ** libgnutls: Allow decoding PKCS #8 files with ECC parameters
132 ** libgnutls: Several small bug fixes found by coverity.
134 ** libgnutls: The conditionally available self-test functions
135 were moved to self-test.h.
137 ** libgnutls: Fixed issue with the check of incoming data when two
138 different recv and send pointers have been specified. Reported and
139 investigated by JMRecio.
141 ** libgnutls: Fixed issue in the RSA-PSK key exchange, which would
142 result to illegal memory access if a server hint was provided. Reported
145 ** libgnutls: Fixed client memory leak in the PSK key exchange, if a
146 server hint was provided.
148 ** libgnutls: Corrected the *get_*_othername_oid() functions.
150 ** API and ABI modifications:
151 No changes since last version.
154 * Version 3.3.0 (released 2014-04-10)
156 ** libgnutls: The initialization of the library was moved to a
157 constructor. That is, gnutls_global_init() is no longer required
158 unless linking with a static library or a system that does not
159 support library constructors.
161 ** libgnutls: static libraries are not built by default.
163 ** libgnutls: PKCS #11 initialization is delayed to first usage.
164 That avoids long delays in gnutls initialization due to broken PKCS #11
167 ** libgnutls: The PKCS #11 subsystem is re-initialized "automatically"
168 on the first PKCS #11 API call after a fork.
170 ** libgnutls: certificate verification profiles were introduced
171 that can be specified as flags to verification functions. They
172 are enumerations in gnutls_certificate_verification_profiles_t
173 and can be converted to flags for use in a verification function
174 using GNUTLS_PROFILE_TO_VFLAGS().
176 ** libgnutls: Added the ability to read system-specific initial
177 keywords, if they are prefixed with '@'. That allows a compile-time
178 specified configuration file to be used to read pre-configured priority
179 strings from. That can be used to impose system specific policies.
181 ** libgnutls: Increased the default security level of priority
182 strings (NORMAL and PFS strings require at minimum a 1008 DH prime),
183 and set a verification profile by default. The LEGACY keyword is
184 introduced to set the old defaults.
186 ** libgnutls: Added support for the name constraints PKIX extension.
187 Currently only DNS names and e-mails are supported (no URIs, IPs
190 ** libgnutls: Security parameter SEC_PARAM_NORMAL was renamed to
191 SEC_PARAM_MEDIUM to avoid confusion with the priority string NORMAL.
193 ** libgnutls: Added new API in x509-ext.h to handle X.509 extensions.
194 This API handles the X.509 extensions in isolation, allowing to parse
195 similarly formatted extensions stored in other structures.
197 ** libgnutls: When generating DSA keys the macro GNUTLS_SUBGROUP_TO_BITS
198 can be used to specify a particular subgroup as the number of bits in
199 gnutls_privkey_generate; e.g., GNUTLS_SUBGROUP_TO_BITS(2048, 256).
201 ** libgnutls: DH parameter generation is now delegated to nettle.
202 That unfortunately has the side-effect that DH parameters longer than
203 3072 bits, cannot be generated (not without a nettle update).
205 ** libgnutls: Separated nonce RNG from the main RNG. The nonce
206 random number generator is based on salsa20/12.
208 ** libgnutls: The buffer alignment provided to crypto backend is
209 enforced to be 16-byte aligned, when compiled with cryptodev
210 support. That allows certain cryptodev drivers to operate more
213 ** libgnutls: Return error when a public/private key pair that doesn't
214 match is set into a credentials structure.
216 ** libgnutls: Depend on p11-kit 0.20.0 or later.
218 ** libgnutls: The new padding (%NEW_PADDING) experimental TLS extension has
219 been removed. It was not approved by IETF.
221 ** libgnutls: The experimental xssl library is removed from the gnutls
224 ** libgnutls: Reduced the number of gnulib modules used in the main library.
226 ** libgnutls: Added priority string %DISABLE_WILDCARDS.
228 ** libgnutls: Added the more extensible verification function
229 gnutls_certificate_verify_peers(), that allows checking, in addition
230 to a peer's DNS hostname, for the key purpose of the end certificate
231 (via PKIX extended key usage).
233 ** certtool: Timestamps for serial numbers were increased to 8 bytes,
234 and in batch mode to 12 (appended with 4 random bytes).
236 ** certtool: When no CRL number is provided (or value set to -1), then
237 a time-based number will be used, similarly to the serial generation
238 number in certificates.
240 ** certtool: Print the SHA256 fingerprint of a certificate in addition
243 ** libgnutls: Added --enable-fips140-mode configuration option (unsupported).
244 That option enables (when running on FIPS140-enabled system):
245 o RSA, DSA and DH key generation as in FIPS-186-4 (using provable primes)
246 o The DRBG-CTR-AES256 deterministic random generator from SP800-90A.
247 o Self-tests on initialization on ciphers/MACs, public key algorithms
248 and the random generator.
249 o HMAC-SHA256 verification of the library on load.
250 o MD5 is included for TLS purposes but cannot be used by the high level
252 o All ciphers except AES are disabled.
253 o All MACs and hashes except GCM and SHA are disabled (e.g., HMAC-MD5).
254 o All keys (temporal and long term) are zeroized after use.
255 o Security levels are adjusted to the FIPS140-2 recommendations (rather

575 ** libgnutls: Corrected parsing issue in XMPP within a subject
576 alternative name. Reported by James Cloos.
578 ** libgnutls: gnutls_pkcs11_reinit() will reinitialize all PKCS #11
579 modules, and not only the ones loaded via p11-kit.
581 ** libgnutls: Added function to check whether the private key is
582 still available (inserted).
584 ** libgnutls: Try to detect fork even during nonce generation.
586 ** API and ABI modifications:
587 gnutls_handshake_set_random: Added
588 gnutls_transport_set_int2: Added
589 gnutls_transport_get_int2: Added
590 gnutls_transport_get_int: Added
591 gnutls_record_cork: Exported
592 gnutls_record_uncork: Exported
593 gnutls_pkcs11_privkey_status: Added
596 * Version 3.1.8 (released 2013-02-10)
598 ** libgnutls: Fixed issue in gnutls_x509_privkey_import2() which didn't return
599 GNUTLS_E_DECRYPTION_FAILED in all cases, and affect certtool operation
600 with encrypted keys. Reported by Yan Fiz.
602 ** libgnutls: The minimum DH bits accepted by priorities NORMAL and
603 PERFORMANCE was set to previous defaults 727 bits. Reported by Diego
606 ** libgnutls: Corrected issue which prevented gnutls_pubkey_verify_hash()
607 to operate with long keys. Reported by Erik A Jensen.
609 ** API and ABI modifications:
610 No changes since last version.
613 * Version 3.1.7 (released 2013-02-04)
615 ** certtool: Added option "dn" which allows to directly set the DN
616 in a template from an RFC4514 string.
618 ** danetool: Added options: --dlv and --insecure. Suggested by Paul Wouters.
620 ** libgnutls-xssl: Added a new library to simplify GnuTLS usage.
622 ** libgnutls-dane: Added function to specify a DLV file.
624 ** libgnutls: Heartbeat code was made optional.
626 ** libgnutls: Fixes in server side of DTLS-0.9.
628 ** libgnutls: DN variable 'T' was expanded to 'title'.
630 ** libgnutls: Fixes in record padding parsing to prevent a timing attack.
631 Issue reported by Kenny Paterson and Nadhem Alfardan.
633 ** libgnutls: Added functions to directly set the DN in a certificate
634 or request from an RFC4514 string.
636 ** libgnutls: Optimizations in the random generator. The re-seeding of
637 it is now explicitly done on every session deinit.
639 ** libgnutls: Simplified the DTLS sliding window implementation.
641 ** libgnutls: The minimum DH bits accepted by a client are now set
642 by the specified priority string. The current values correspond to the
643 previous defaults (727 bits), except for the SECURE128 and SECURE192
644 strings which increase the minimum to 1248 and 1776 respectively.
646 ** libgnutls: Added the gnutls_record_cork() and uncork API to enable
647 buffering in sending application data.
649 ** libgnutls: Removed default random padding, and added a length-hiding interface
650 instead. Both the server and the client must support this extension. Whether
651 length-hiding can be used on a given session can be checked using
652 gnutls_record_can_use_length_hiding(). Contributed by Alfredo Pironti.
654 ** libgnutls: Added the experimental %NEW_PADDING priority string. It enables
655 a new padding mechanism in TLS allowing arbitrary padding in TLS records
656 in all ciphersuites, which makes length-hiding more efficient and solves
657 the issues with timing attacks on CBC ciphersuites.
659 ** libgnutls: Corrected gnutls_cipher_decrypt2() when used with AEAD
660 ciphers (i.e., AES-GCM). Reported by William McGovern.

699 ** libgnutls: gnutls_x509_crt_get_policy() allows for a list of zero
702 ** libgnutls: Ignore heartbeat messages when received out-of-order,
703 instead of issuing an error.
705 ** libgnutls: Stricter RSA PKCS #1 1.5 encoding and decoding. Reported
708 ** libgnutls: TPM support is disabled by default because GPL programs
709 cannot link with it. Use --with-tpm to enable it.
711 ** libgnutls-guile: Fixed parallel compilation issue.
713 ** gnutls-cli: It will try to connect to all possible returned addresses
716 ** API and ABI modifications:

722 ** libgnutls: Added functions to parse the certificates policies
725 ** libgnutls: Handle BMPString (UCS-2) encoding in the Distinguished
726 Name by translating it to UTF-8 (works on windows or systems with iconv).
728 ** libgnutls: Added PKCS #11 key generation function that returns the
729 public key on generation.
731 ** libgnutls: Corrected bug in priority string parsing, that mostly
732 affected combined levels. Patch by Tim Kosse.
734 ** certtool: The --pubkey-info option can be combined with the
735 --load-privkey or --load-request to print the corresponding public keys.
737 ** certtool: It is able to set certificate policies via a template.
739 ** certtool: Added --hex-numbers option which prints big numbers in
740 an easier to parse format.
742 ** p11tool: After key generation, outputs the public key (useful in
743 tokens that do not store the public key).
745 ** danetool: It is being built even without libgnutls-dane (the
746 --check functionality is disabled though).
748 ** API and ABI modifications:
749 gnutls_pkcs11_privkey_generate2: Added
750 gnutls_x509_crt_get_policy: Added

760 ** libgnutls: gnutls_certificate_verify_peers2() will set flags depending on
761 the available revocation data validity.
763 ** libgnutls: Added gnutls_certificate_verification_status_print(),
764 a function to print the verification status code in human readable text.
766 ** libgnutls: Added priority string %VERIFY_DISABLE_CRL_CHECKS.
768 ** libgnutls: Simplified certificate verification by adding
769 gnutls_certificate_verify_peers3().

840 response corresponds to the given certificate.
842 ** libgnutls: In client side gnutls_init() enables the session ticket and
843 OCSP certificate status request extensions by default. The flag
844 GNUTLS_NO_EXTENSIONS can be used to prevent that.
846 ** libgnutls: Several updates in the OpenPGP code. The generating code
847 is fully RFC6091 compliant and RFC5081 support is only supported in client
850 ** libgnutls-dane: Added. It is a library to provide DANE with DNSSEC
851 certificate verification.
853 ** gnutls-cli: Added --dane option to enable DANE certificate verification.

895 of certificates in the windows platform.
897 ** libgnutls: Corrected bug in OpenPGP subpacket encoding.
899 ** libgnutls: Added support for DTLS/TLS heartbeats by Olga Smolenchuk.
900 (the work was done during Google Summer of Code).
902 ** libgnutls: Added X.509 certificate verification flag
903 GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN. This flag allows the verification
904 of unsorted certificate chains and is enabled by default for
905 TLS certificate verification (if gnutls_certificate_set_verify_flags()
906 does not override it).
908 ** libgnutls: Prints warning on certificates that contain keys of
909 an insecure level. If the %COMPAT priority flag is not specified
910 the TLS connection fails.
912 ** libgnutls: Correctly restore gnutls_record_recv() in DTLS mode
913 if interrupted during the retrasmition of handshake data.
915 ** libgnutls: Better mingw32 support (patch by LRN).
917 ** libgnutls: The %COMPAT keyword, if specified, will tolerate
918 key usage violation errors (they are far too common to ignore).
920 ** libgnutls: Added GNUTLS_STATELESS_COMPRESSION flag to gnutls_init(),
921 which provides a tool to counter compression-related attacks where
922 parts of the data are controlled by the attacker _and_ are placed in
923 separate records (use with care - do not use compression if not sure).
925 ** libgnutls: Depends on libtasn1 2.14 or later.
927 ** certtool: Prints the number of bits of the public key algorithm
928 parameter in a private key.
930 ** API and ABI modifications:
931 gnutls_x509_privkey_get_pk_algorithm2: Added

939 GNUTLS_SEC_PARAM_INSECURE: Added
941 * Version 3.1.1 (released 2012-09-02)
943 ** gnutls-serv: Listens on IPv6. Patch by Bernhard R. Link.
945 ** certtool: Changes in password handling of certtool.
946 Ask password when required and only if the '--password' option is not
947 given. If the '--password' option is given during key generation then
948 assume the PKCS #8 file format, instead of ignoring the password.
950 ** tpmtool: No longer asks for key password in registered keys.
952 ** libgnutls: Elliptic curve code was optimized by Ilya Tumaykin.
953 wmNAF is now used for point multiplication and other optimizations.
954 (the major part of the work was done during Google Summer of Code).
956 ** libgnutls: The default pull_timeout_function only uses select
957 instead of a combination of select() and recv() to prevent issues
958 when used in stream sockets in some systems.
960 ** libgnutls: Be tolerant in ECDSA signature violations (e.g. using
961 SHA256 with a SECP384 curve instead of SHA-384), to interoperate with
964 ** libgnutls: Fixed DSA and ECDSA signature generation in smart
965 cards. Thanks to Andreas Schwier from cardcontact.de for providing
966 me with ECDSA capable smart cards.
968 ** API and ABI modifications:
969 gnutls_sign_algorithm_get: Added
970 gnutls_sign_get_hash_algorithm: Added
971 gnutls_sign_get_pk_algorithm: Added
974 * Version 3.1.0 (released 2012-08-15)
976 ** libgnutls: Added direct support for TPM as a cryptographic module
977 in gnutls/tpm.h. TPM keys can be used in functions accepting files
978 using URLs of the following types:
979 tpmkey:file=/path/to/file
980 tpmkey:uuid=7f468c16-cb7f-11e1-824d-b3a4f4b20343;storage=user
982 ** libgnutls: Priority string level keywords can be combined.
983 For example the string "SECURE256:+SUITEB128" is now allowed.
985 ** libgnutls: requires libnettle 2.5.
987 ** libgnutls: Use the PKCS #1 1.5 encoding provided by nettle (2.5)
988 for encryption and signatures.
990 ** libgnutls: Added GNUTLS_CERT_SIGNATURE_FAILURE to differentiate between
991 generic errors and signature verification errors in the verification
994 ** libgnutls: Added gnutls_pkcs12_simple_parse() as a helper function
995 to simplify parsing in most PKCS #12 use cases.
997 ** libgnutls: gnutls_certificate_set_x509_simple_pkcs12_file() adds
998 the whole certificate chain (if any) to the credentials structure, instead
999 of only the end-user certificate.
1001 ** libgnutls: Key import functions such as gnutls_pkcs12_simple_parse()
1002 and gnutls_x509_privkey_import_pkcs8(), return consistently
1003 GNUTLS_E_DECRYPTION_FAILED if the input structure is encrypted but no
1004 password was provided.
1006 ** libgnutls: Added gnutls_handshake_set_timeout() a function that
1007 allows to set the maximum time spent in a handshake.
1009 ** libgnutlsxx: Added session::set_transport_vec_push_function. Patch
1012 ** tpmtool: Added. It is a tool to generate private keys in the
1015 ** gnutls-cli: --benchmark-tls was split to --benchmark-tls-kx
1016 and --benchmark-tls-ciphers
1018 ** certtool: generated PKCS #12 structures may hold more than one
1019 private key. Patch by Lucas Fisher.
1021 ** certtool: Added option --null-password to generate/decrypt keys
1022 that use a NULL password (in schemas that distinguish between NULL
1023 an empty passwords).
1025 ** minitasn1: Upgraded to libtasn1 version 2.13.

1070 * Version 3.0.22 (released 2012-08-04)
1072 ** libgnutls: gnutls_certificate_set_x509_system_trust()
1073 is now supported on OpenBSD.
1075 ** libgnutls: When verifying a certificate chain make sure it is chain.
1076 If the chain is wronly interrupted at some point then truncate it,
1077 and only try to verify the correct part. Patch by David Woodhouse
1079 ** libgnutls: Restored the behavior of gnutls_x509_privkey_import_pkcs8()
1080 which now may (again) accept a NULL password.
1082 ** certtool: Allow the user to choose the hash algorithm
1083 when signing certificate request or certificate revocation list.
1084 Patch by Petr PĂsaÅ™.
1086 ** API and ABI modifications:

1092 ** libgnutls: fixed bug in gnutls_x509_privkey_import()
1093 that prevented the loading of EC private keys when DER
1094 encoded. Reported by David Woodhouse.
1096 ** libgnutls: In DTLS larger to mtu records result to
1097 GNUTLS_E_LARGE_PACKET instead of being truncated.
1099 ** libgnutls: gnutls_dtls_get_data_mtu() is more precise. Based
1100 on patch by David Woodhouse.
1102 ** libgnutls: Fixed memory leak in PKCS #8 key import.
1104 ** libgnutls: Added support for an old version of the DTLS protocol
1105 used by openconnect vpn client for compatibility with Cisco's AnyConnect
1106 SSL VPN. It is marked as GNUTLS_DTLS0_9. Do not use it for newer protocols
1109 ** libgnutls: Corrected bug that prevented resolving PKCS #11 URLs
1110 if only the label is specified. Patch by David Woodhouse.

1477 allow listing the ciphersuites enabled in a priority structure.
1478 It outputs an index to be used in gnutls_get_cipher_suite_info().
1480 ** libgnutls: Optimizations in the elliptic curve code --timing
1481 attacks resistant code is only used in ECDSA private key operations.

1781 verify data provided the signature algorithm.
1783 ** libgnutls: Simplified the handling of handshake messages to
1784 be hashed. Instead of hashing during the handshake process we now
1785 keep the data until handshake is over and hash them on request.
1786 This uses more memory but eliminates issues with TLS 1.2 and
1789 ** libgnutls: Added AES-GCM optimizations using the PCLMULQDQ
1790 instruction. Uses Andy Polyakov's assembly code.
1792 ** libgnutls: Added gnutls_x509_trust_list_add_named_crt() and
1793 gnutls_x509_trust_list_verify_named_crt() that allow having a
1794 list of certificates in the trusted list that will be associated
1795 with a name (e.g. server name) and will not be used as CAs.
1797 ** libgnutls: PKCS #11 back-end rewritten to use p11-kit

1933 in the Certificate Verify message when in TLS 1.2. Reported
1936 ** libgnutlsxx: The C++ interface returns exception on
1937 every error and not only on fatal ones. This allows easier
1940 ** libgnutls: Corrected issue in DHE-PSK ciphersuites that ignored
1943 ** libgnutls: SRP and PSK are no longer set on the default priorities.
1944 They have to be explicitly set.

2237 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
2238 to use the libgcrypt back end.
2240 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
2241 backend crypto library.
2243 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
2245 ** libgnutls: Several updates in the buffering internal interface.
2247 ** libgnutls: Is now more liberal in the PEM decoding. That is spaces and
2248 tabs are being skipped.
2250 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
2252 ** libgnutls: The %COMPAT flag now allows larger records that violate the
2255 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
2256 system calls. Applications that depended on it being 1 should explicitly call
2257 gnutls_transport_set_lowat().
2259 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
2260 to ECRYPT II recommendations. Mappings were moved to a single location
2261 and DSA keys are handled differently (since DSA2 allows for 1024,2048
2262 and 3072 keys only).
2264 ** libgnutls: gnutls_x509_privkey_import() will fallback to
2265 gnutls_x509_privkey_import_pkcs8() without a password, if it
2266 is unable to decode the key.
2268 ** libgnutls: HMAC-MD5 no longer used by default.
2270 ** API and ABI modifications:
2271 gnutls_openpgp_privkey_sec_param: ADDED
2272 gnutls_x509_privkey_sec_param: ADDED
2274 * Version 2.11.0 (released 2010-07-22)
2276 ** libgnutls: support scattered write using writev(). This takes
2277 advantage of the new buffering layer and allows queuing of packets
2278 and flushing them. This is currently used for handshake messages
2281 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
2282 alternative locking procedures. By default the system available
2283 locking is used. In *NIX pthreads are used and in windows the
2284 critical section API. This follows a different approach than the
2285 previous versions that depended on libgcrypt initialization. The
2286 locks are now set by default in systems that support it. Programs
2287 that used gcry_control() to set thread locks should insert it into
2289 #if GNUTLS_VERSION_NUMBER <= 0x020b00
2293 ** libgnutls: Added support for reading DN from EV-certificates.
2295 jurisdictionOfIncorporationLocalityName,
2296 jurisdictionOfIncorporationStateOrProvinceName,
2297 jurisdictionOfIncorporationCountryName
2299 ** libgnutls: Added support for DSA signing/verifying with bit
2302 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
2303 has to be called to register any required md5 handlers.
2305 ** libgnutls: Internal buffering code was replaced by simpler
2306 code contributed by Jonathan Bastien-Filiatrault.
2308 ** libgnutls: Internal API for extensions augmented to allow
2309 safe storing and loading of data on resumption. This allows writing
2310 self-contained extensions (when possible). As a side effect
2311 the OPRFI extension was removed.
2313 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
2315 ** libgnutls: Added PKCS #11 support and an API to access objects in
2316 gnutls/pkcs11.h. Currently certificates and public keys can be
2317 imported from tokens, and operations can be performed on private keys.
2319 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
2321 ** libgnutls: Added initial support for the nettle library. It uses
2322 the system's random generator for seeding. That is /dev/urandom in Linux,
2323 system calls in Win32 and EGD on other systems.
2325 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
2326 works even when resuming a session.
2328 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
2329 similar gnutls_certificate_set_server_retrieve_function() and
2330 gnutls_certificate_set_client_retrieve_function(). In addition it support
2331 PKCS #11 private keys.
2333 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
2334 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
2336 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
2337 sizes for private keys using a human understandable scale.
2339 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
2340 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
2341 --pkcs11-delete-url, --pkcs11-write
2343 certtool: The --pkcs-cipher is taken into account when generating a
2344 private key. The default cipher used now is aes-128. The old behavior can
2345 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
2347 certtool: Added --certificate-pubkey to print the public key of the
2350 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
2351 can now accept a PKCS #11 URL in addition to a file. This will allow for
2352 example to use the Gnome-keyring trusted certificate list to verify
2353 connections using a url such as:
2354 pkcs11:token=Root%20CA%20Certificates;serial=1%3AROOTS%3ADEFAULT;model=1%2E0;manufacturer=Gnome%20Keyring

2435 * Version 2.10.1 (released 2010-07-25)
2437 ** libgnutls: Added support for broken certificates that indicate RSA
2440 ** gnutls-cli: Allow verification using V1 CAs.
2442 ** libgnutls: gnutls_x509_privkey_import() will fallback to
2443 gnutls_x509_privkey_import_pkcs8() without a password, if it
2444 is unable to decode the key.
2446 ** libgnutls: Correctly deinitialize crypto API functions to prevent
2447 a memory leak. Reported by Mads Kiilerich.
2449 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
2450 issue a warning, that the output key might not be working everywhere.
2452 ** certtool: The --pkcs-cipher is taken into account when generating a
2453 private key. The default cipher used now is aes-128. The old behavior
2454 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
2456 ** API and ABI modifications:
2457 No changes since last version.
2459 * Version 2.10.0 (released 2010-06-25)
2461 ** API and ABI modifications:
2462 No changes since last version.
2464 * Version 2.9.12 (released 2010-06-17)
2466 ** gnutls-cli: Make --starttls work again.
2467 Problem introduced in patch to use read() instead of fgets() committed
2470 ** API and ABI modifications:
2471 No changes since last version.
2473 * Version 2.9.11 (released 2010-06-07)
2475 ** libgnutls: Removed two APIs related to safe renegotiation.
2476 Use priority strings instead. The APIs were
2477 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
2478 (Remember that we don't promise ABI stability during development
2479 series, so this doesn't cause an shared library ABI increment.)
2481 ** tests: More self testing of safe renegotiation extension.
2482 See tests/safe-renegotiation/README for more information.
2484 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
2486 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
2488 ** API and ABI modifications:
2489 gnutls_safe_negotiation_set_initial: REMOVED.
2490 gnutls_safe_renegotiation_set: REMOVED.
2492 * Version 2.9.10 (released 2010-04-22)
2494 ** libgnutls: Time verification extended to trusted certificate list.
2495 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
2498 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
2499 Based on patch by Pavan Konjarla. Adds new constant
2500 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
2502 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
2503 Solves the issue discussed in:
2504 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
2505 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
2506 Note that to allow connecting to unpatched servers the full protection
2507 is only enabled if the priority string %SAFE_RENEGOTIATION is
2508 specified. You can check whether protection is in place by querying
2509 gnutls_safe_renegotiation_status(). New error codes
2510 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
2511 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
2513 ** libgnutls: When checking openpgp self signature also check the signatures
2515 Ilari Liusvaara noticed and reported the issue and provided test
2518 ** libgnutls: Added cryptodev support (/dev/crypto).
2519 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
2520 benchmark utility for AES. Adds new error codes
2521 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
2523 ** libgnutls: Exported API to access encryption and hash algorithms.
2524 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
2525 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
2526 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
2527 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
2528 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
2529 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
2530 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
2532 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
2533 verification of certificate upon receipt rather than waiting until the
2534 end of the handshake.
2536 ** libgnutls: Don't send alerts during handshake.
2537 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
2539 ** certtool: Corrected two issues that affected certificate request generation.
2540 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
2541 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
2542 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
2543 those parameters there since other implementations don't do either and having
2544 them does not seem to offer anything (anyway you need the signer's certificate
2545 to verify thus public key will be available). Found thanks to Boyan Kasarov.
2546 This however has the side-effect that public key IDs shown by certtool are
2547 now different than previous gnutls releases.
2548 (3) the option --pgp-certificate-info will verify self signatures
2550 ** certtool: Allow exporting of Certificate requests on DER format.
2552 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
2554 ** gnutls-cli: Handle reading binary data from server.

2617 No changes since last version.
2619 * Version 2.9.8 (released 2009-11-05)
2621 ** libgnutls: Fix for memory leaks on interrupted handshake.
2622 Reported by Tang Tong.
2624 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
2625 ** extension and certificate verify field.
2626 This requires changes for TLS 1.2 servers and clients that use
2627 callbacks for certificate retrieval. They are now required to check
2628 with gnutls_sign_algorithm_get_requested() whether the certificate
2629 they send complies with the peer's preferences in signature
2632 ** libgnutls: In server side when resuming a session do not overwrite the
2633 ** initial session data with the resumed session data.
2635 ** libgnutls: Added support for AES-128, AES-192 and AES-256 in PKCS #8
2637 This affects also PKCS #12 encoded files. This adds the following new
2638 enums: GNUTLS_CIPHER_AES_192_CBC, GNUTLS_PKCS_USE_PBES2_AES_128,
2639 GNUTLS_PKCS_USE_PBES2_AES_192, GNUTLS_PKCS_USE_PBES2_AES_256.
2641 ** libgnutls: Fix PKCS#12 encoding.
2642 The error you would get was "The OID is not supported.". Problem
2643 introduced for the v2.8.x branch in 2.7.6.
2645 ** certtool: Added the --pkcs-cipher option.
2646 To explicitely specify the encryption algorithm to use.
2648 ** tests: Added "pkcs12_encode" self-test to check PKCS#12 functions.
2650 ** tests: Fix time bomb in chainverify self-test.
2651 Reported by Andreas Metzler <ametzler@downhill.at.eu.org> in
2652 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3925>.
2654 ** tests: Fix expired cert in chainverify self-test.
2656 ** i18n: Vietnamese translation updated.

2691 ** libgnutls: Add new functions to extract X.509 Issuer Alternative Names.
2692 The new functions are gnutls_x509_crt_get_issuer_alt_name2,
2693 gnutls_x509_crt_get_issuer_alt_name, and
2694 gnutls_x509_crt_get_issuer_alt_othername_oid. Contributed by Brad

2718 ** Fix use of deprecated types internally.
2719 Use of deprecated types in GnuTLS from now on will lead to a compile
2720 error, to prevent this from happening again.
2722 ** API and ABI modifications:
2723 No changes since last version.
2725 * Version 2.9.3 (released 2009-08-19)
2727 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
2728 The new APIs are gnutls_session_ticket_enable_client,
2729 gnutls_session_ticket_enable_server, and
2730 gnutls_session_ticket_key_generate.
2732 ** gnutls-cli, gnutls-serv: New parameter --noticket to disable TLS tickets.
2734 ** API and ABI modifications:
2735 gnutls_session_ticket_key_generate: ADDED.
2736 gnutls_session_ticket_enable_client: ADDED.
2737 gnutls_session_ticket_enable_server: ADDED.
2739 * Version 2.9.2 (released 2009-08-14)
2741 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
2742 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
2743 into 1) not printing the entire CN/SAN field value when printing a
2744 certificate and 2) cause incorrect positive matches when matching a
2745 hostname against a certificate. Some CAs apparently have poor
2746 checking of CN/SAN values and issue these (arguable invalid)
2747 certificates. Combined, this can be used by attackers to become a
2748 MITM on server-authenticated TLS sessions. The problem is mitigated
2749 since attackers needs to get one certificate per site they want to
2750 attack, and the attacker reveals his tracks by applying for a
2751 certificate at the CA. It does not apply to client authenticated TLS
2752 sessions. Research presented independently by Dan Kaminsky and Moxie
2753 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
2754 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
2756 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
2757 The function may fail incorrectly when an earlier certificate was
2758 imported to the same gnutls_x509_crt_t structure.
2760 ** minitasn1: Internal copy updated to libtasn1 v2.3.
2762 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.

2791 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
2792 Before we required that the runtime library used the same (or more
2793 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
2794 that the runtime usage is above the minimum required. Reported by
2795 Marco d'Itri <md@linux.it> via Andreas Metzler
2796 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.

2833 ** libgnutls: For CSRs, don't null pad integers for RSA/DSA value.
2834 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
2835 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
2837 Note: As a side effect of this change, the "public key identifier"
2838 value computed for a certificate using this version of GnuTLS will be
2839 different from values computed using earlier versions of GnuTLS.
2841 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
2842 ** optional SignatureAlgorithm parameter field.
2843 VeriSign rejected these CSRs. They are stricly speaking not needed
2844 since you need the signer's certificate to verify the certificate
2845 signature anyway. Reported by Wilankar Trupti

3105 No offically supported interfaces have been modified or removed. The
3106 library should be completely backwards compatible on both the source
3109 The shared library no longer exports some symbols that have never been
3110 officially supported, i.e., not mentioned in any of the header files.
3116 Normally when symbols are removed, the shared library version has to
3117 be incremented. This leads to a significant cost for everyone using
3118 the library. Because none of the above symbols have ever been
3119 intended for use by well-behaved applications, we decided that the it
3120 would be better for those applications to pay the price rather than
3121 incurring problems on the majority of applications.
3123 If it turns out that applications have been using unofficial
3124 interfaces, we will need to release a follow-on release on the v2.8
3125 branch to exports additional interfaces. However, initial testing
3126 suggests that few if any applications have been using any of the
3129 Although not a new change compared to 2.6.x, we'd like to remind you
3130 interfaces have been modified so that X.509 chain verification now
3131 also checks activation/expiration times on certificates. The affected
3134 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.

3139 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
3141 This change in behaviour was made during the GnuTLS 2.6.x cycle, and
3142 we gave our rationale for it in earlier release notes.

3300 * Version 2.7.8 (released 2009-05-03)
3302 ** libgnutls: Fix DSA key generation.
3303 Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
3305 ** libgnutls: Check expiration/activation time on untrusted certificates.
3306 Merged from stable branch. Reported by Romain Francoise
3307 <romain@orebokech.com>. This changes the semantics of
3308 gnutls_x509_crt_list_verify, which in turn is used by
3309 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
3310 We add two new gnutls_certificate_status_t codes for reporting the new
3311 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
3312 We also add a new gnutls_certificate_verify_flags flag,
3313 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
3314 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
3316 ** lib: Linker version scripts reduces number of exported symbols.
3317 The linker version script now lists all exported ABIs explicitly, to
3318 avoid accidentally exporting unintended functions. Compared to
3319 before, most symbols beginning with _gnutls* are no longer exported.
3320 These functions have never been intended for use by applications, and
3321 there were no prototypes for these function in the public header
3322 files. Thus we believe it is possible to do this without incrementing
3323 the library ABI version which normally has to be done when removing an
3326 ** lib: Limit exported symbols on systems without LD linker scripts.
3327 Before all symbols were exported. Now we limit the exported symbols
3328 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
3329 _gnutls*. This is a superset of the actual supported ABI, but still
3330 an improvement compared to before. This is implemented using Libtool
3331 -export-symbols-regex. It is more portable than linker version
3334 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
3335 This should have been done in the last release.
3337 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
3338 Reported by Peter Hendrickson <pdh@wiredyne.com> in
3339 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
3341 ** doc: Improved sections for the info manual.
3342 We now follow the advice given by the texinfo manual on which
3343 directory categories to use. In particular, libgnutls moved from the
3344 'GNU Libraries' section to the 'Software libraries' and the command
3345 line tools moved from 'Network Applications' to 'System
3348 ** API and ABI modifications:
3349 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
3350 gnutls_certificate_verify_peers: Likewise.
3351 gnutls_certificate_verify_peers2: Likewise.
3352 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
3353 GNUTLS_CERT_EXPIRED: ADDED.
3354 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
3356 * Version 2.7.7 (released 2009-04-20)
3358 ** libgnutls: Applied patch by Cedric Bail to add functions
3359 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
3361 ** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.

3363 <http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3467>.
3365 ** minitasn1: Internal copy updated to libtasn1 v1.8.
3366 GnuTLS is also internally ready to be used with libtasn1 v2.0.
3368 ** doc: Fix build failure of errcodes/printlist.
3369 Reported by Roman Bogorodskiy <novel@FreeBSD.org> in
3370 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3435>.
3372 ** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
3373 It is currently only used by the core library. This will enable a new
3374 domain 'gnutls' for translations of the command line tools.
3376 ** Corrected possible memory corruption on signature verification failure.
3377 Reported by Miroslav Kratochvil <exa.exa@gmail.com>
3379 ** API and ABI modifications:
3380 gnutls_x509_crt_verify_hash: ADDED
3381 gnutls_x509_crt_get_verify_algorithm: ADDED
3383 * Version 2.7.6 (released 2009-02-27)
3385 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
3386 This applies both to generating certificates and certificate requests.
3388 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
3390 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
3391 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
3392 be used for chain verification.
3394 ** gnutls-serv: No longer disable MAC padding by default.
3395 Use --priority NORMAL:%COMPAT to disable MAC padding again.
3397 ** gnutls-cli: Certificate information output format changed.
3398 The tool now uses libgnutls' functions to print certificate
3399 information. This avoids code duplication.
3401 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
3402 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
3403 They can be used to override the default certificate chain validation
3406 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
3407 specify the client hello message record version. Used to overcome buggy
3408 TLS servers. Report by Martin von Gagern.
3410 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
3412 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
3414 ** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
3416 ** API and ABI modifications:
3417 No changes since last version.
3419 * Version 2.7.5 (released 2009-02-06)
3421 ** libgnutls: Accept chains where intermediary certs are trusted.
3422 Before GnuTLS needed to validate the entire chain back to a
3423 self-signed certificate. GnuTLS will now stop looking when it has
3424 found an intermediary trusted certificate. The new behaviour is
3425 useful when chains, for example, contains a top-level CA, an
3426 intermediary CA signed using RSA-MD5, and an end-entity certificate.
3427 To avoid chain validation errors due to the RSA-MD5 cert, you can
3428 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
3429 The signature on trusted certificates are not checked, so the chain
3430 has a chance to validate correctly. Reported by "Douglas E. Engert"
3431 <deengert@anl.gov> in
3432 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3434 ** libgnutls: result_size in gnutls_hex_encode now holds
3435 the size of the result. Report by John Brooks <special@dereferenced.net>.
3437 ** libgnutls: gnutls_handshake when sending client hello during a
3438 rehandshake, will not offer a version number larger than the current.
3439 Reported by Tristan Hill <stan@saticed.me.uk>.
3441 ** libgnutls: Permit V1 Certificate Authorities properly.
3442 Before they were mistakenly rejected even though
3443 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
3444 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
3445 "Douglas E. Engert" <deengert@anl.gov> in
3446 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3448 ** API and ABI modifications:
3449 No changes since last version.
3451 * Version 2.7.4 (released 2009-01-07)
3453 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
3454 This is a bugfix -- the previous attempt to do this from internal x509
3455 certificate verification procedures did not return the correct value
3456 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
3457 <dkg@fifthhorseman.net> in
3458 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
3459 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
3460 Gillmor <dkg@fifthhorseman.net>.
3462 ** libgnutls: New interface to get key id for certificate requests.
3463 Patch from David MarĂn Carreño <davefx@gmail.com> in
3464 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
3466 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
3468 ** certtool: --verify-chain now prints results of using library verification.
3469 Earlier, certtool --verify-chain used its own validation algorithm
3470 which wasn't guaranteed to give the same result as the libgnutls
3471 internal validation algorithm. Now this command print a new final
3472 line with header 'Chain verification output:' that contains the result
3473 from using the internal verification algorithm on the same chain.
3475 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
3477 ** API and ABI modifications:
3478 gnutls_x509_crq_get_key_id: ADDED.
3480 * Version 2.7.3 (released 2008-12-10)
3482 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
3483 Reported by Michael Kiefer <Michael-Kiefer@web.de> in

3485 Andreas Metzler <ametzler@downhill.at.eu.org> in
3486 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
3488 ** libgnutls: Libgcrypt initialization changed.
3489 If libgcrypt has not already been initialized, GnuTLS will now
3490 initialize libgcrypt with disabled secure memory. Initialize
3491 libgcrypt explicitly in your application if you want to enable secure
3492 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
3493 allocation functions, which doesn't use secure memory, so there is no
3494 real change in behaviour.
3496 ** libgnutls: Fix memory leak in PSK authentication.
3497 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
3498 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
3500 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
3502 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
3503 It needs to be invoked before libgcrypt is initialized.
3505 ** gnutls-cli: Return non-zero exit code on error conditions.
3507 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
3509 ** tests: Added chainverify self-test that tests X.509 chain verifications.
3511 ** API and ABI modifications:
3512 No changes since last version.
3514 * Version 2.7.2 (released 2008-11-18)
3516 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
3517 The flaw makes it possible for man in the middle attackers (i.e.,
3518 active attackers) to assume any name and trick GnuTLS clients into
3519 trusting that name. Thanks for report and analysis from Martin von
3520 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
3522 Any updates with more details about this vulnerability will be added
3523 to <http://www.gnu.org/software/gnutls/security.html>
3525 ** libgnutls: Fix namespace issue with version symbols.
3526 The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
3527 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
3528 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
3529 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
3530 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
3531 work but are deprecated.
3533 ** certtool: allow setting arbitrary key purpose object identifiers.
3535 ** libgnutls: Fix detection of C99 macros, to make debug logging work again.
3537 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
3538 Reported by Kevin Quick <quick@sparq.org> in
3539 <https://savannah.gnu.org/support/index.php?106454>.

3544 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3194>.
3546 ** libgnutls: Change detection of when to use a linker version script.
3547 Use --enable-ld-version-script or --disable-ld-version-script to
3548 override auto-detection logic.
3550 ** doc: Change license on the manual to GFDLv1.3+.
3552 ** doc: GTK-DOC fixes for new splitted configuration system.

3557 Tests regressions of the GNUTLS-SA-2008-3 security problem, and the
3558 follow-on problem with crashes on length 1 certificate chains.
3560 ** gnulib: Deprecated modules removed.
3561 Modules include memchr and memcmp.
3563 ** Fix warnings and build GnuTLS with more warnings enabled.
3565 ** minitasn1: Internal copy updated to libtasn1 v1.7.

3582 ** certtool: print a PKCS #8 key even if it is not encrypted.
3584 ** Old libgnutls.m4 and libgnutls-config scripts removed.
3585 Please use pkg-config instead.
3587 ** Configuration system modified.
3588 There is now a configure script in lib/ and libextra/ as well, because
3589 gnulib works better with a config.h per gnulib directory.

3617 Patch by ludo@gnu.org (Ludovic Courtès).
3619 ** Changed detection of libtasn1 and libgcrypt to avoid depending on *-config.
3620 We now require a libgcrypt that has Camellia constants declared in
3621 gcrypt.h, which means v1.3.0 or later.

3651 ** libgnutls: Corrected double free on signature verification failure.
3652 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
3653 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
3655 ** libgnutls: Fix DSA key generation.
3656 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
3657 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
3658 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
3660 ** libgnutls: Check expiration/activation time on untrusted certificates.
3661 Reported by Romain Francoise <romain@orebokech.com>. Before the
3662 library did not check activation/expiration times on certificates, and
3663 was documented as not doing so. We have realized that many
3664 applications that use libgnutls, including gnutls-cli, fail to perform
3665 proper checks. Implementing similar logic in all applications leads
3666 to code duplication. Hence, we decided to check whether the current
3667 time (as reported by the time function) is within the
3668 activation/expiration period of certificates when verifying untrusted
3671 This changes the semantics of gnutls_x509_crt_list_verify, which in
3672 turn is used by gnutls_certificate_verify_peers and
3673 gnutls_certificate_verify_peers2. We add two new
3674 gnutls_certificate_status_t codes for reporting the new error
3675 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
3676 add a new gnutls_certificate_verify_flags flag,
3677 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
3680 More details about the vulnerabilities will be posted at

3683 ** gnutls-cli, gnutls-cli-debug: Fix AIX build problem.
3684 Reported by LAUPRETRE François (P) <francois.laupretre@ratp.fr> in
3685 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3468>.
3687 ** tests: Fix linking of tests/openpgp/keyring self-test.
3688 Reported by Daniel Black in <https://savannah.gnu.org/support/?106543>.
3690 ** API and ABI modifications:
3691 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
3692 gnutls_certificate_verify_peers: Likewise.
3693 gnutls_certificate_verify_peers2: Likewise.
3694 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
3695 GNUTLS_CERT_EXPIRED: ADDED.
3696 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
3698 * Version 2.6.5 (released 2009-04-11)
3700 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
3701 specify the client hello message record version. Used to overcome buggy
3702 TLS servers. Report by Martin von Gagern.
3704 ** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
3705 Libtasn1 0.3.4 or later is required. This is to align with the
3706 upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.
3708 ** API and ABI modifications:
3709 No changes since last version.
3711 * Version 2.6.4 (released 2009-02-06)
3713 ** libgnutls: Accept chains where intermediary certs are trusted.
3714 Before GnuTLS needed to validate the entire chain back to a
3715 self-signed certificate. GnuTLS will now stop looking when it has
3716 found an intermediary trusted certificate. The new behaviour is
3717 useful when chains, for example, contains a top-level CA, an
3718 intermediary CA signed using RSA-MD5, and an end-entity certificate.
3719 To avoid chain validation errors due to the RSA-MD5 cert, you can
3720 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
3721 The signature on trusted certificates are not checked, so the chain
3722 has a chance to validate correctly. Reported by "Douglas E. Engert"
3723 <deengert@anl.gov> in
3724 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3726 ** libgnutls: result_size in gnutls_hex_encode now holds
3727 the size of the result. Report by John Brooks <special@dereferenced.net>.
3729 ** libgnutls: gnutls_handshake when sending client hello during a
3730 rehandshake, will not offer a version number larger than the current.
3731 Reported by Tristan Hill <stan@saticed.me.uk>.
3733 ** libgnutls: Permit V1 Certificate Authorities properly.
3734 Before they were mistakenly rejected even though
3735 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
3736 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
3737 "Douglas E. Engert" <deengert@anl.gov> in
3738 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3740 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
3741 This is a bugfix -- the previous attempt to do this from internal x509
3742 certificate verification procedures did not return the correct value
3743 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
3744 <dkg@fifthhorseman.net> in
3745 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
3746 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn

3765 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
3766 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
3768 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
3769 It needs to be invoked before libgcrypt is initialized.
3771 ** gnutls-cli: Return non-zero exit code on error conditions.
3773 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
3775 ** API and ABI modifications:
3776 No changes since last version.
3778 * Version 2.6.2 (released 2008-11-12)
3780 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
3781 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
3782 problem for certificate chains that contained just one self-signed
3783 certificate. Reported by Michael Meskes <meskes@debian.org> in
3784 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505279>.
3786 ** API and ABI modifications:
3787 No changes since last version.
3789 * Version 2.6.1 (released 2008-11-10)
3791 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
3792 The flaw makes it possible for man in the middle attackers (i.e.,
3793 active attackers) to assume any name and trick GnuTLS clients into
3794 trusting that name. Thanks for report and analysis from Martin von
3795 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
3797 Any updates with more details about this vulnerability will be added

3809 It incorrectly returned the subject DN instead of issuer DN in v2.6.0.
3810 Thanks to Thomas Viehmann <tv@beamnet.de> for report.
3812 ** certtool: Print a PKCS #8 key even if it is not encrypted.
3814 ** tests: Make tests compile when using internal libtasn1.
3815 Patch by ludo@gnu.org (Ludovic Courtès).
3817 ** API and ABI modifications:
3818 No changes since last version.
3820 * Version 2.6.0 (released 2008-10-06)
3822 ** libgnutls: Correct printing and parsing of IPv6 addresses.
3824 ** libgnutls-openssl: fix out of bounds access.
3825 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
3826 from Thomas Viehmann <tv@beamnet.de>.
3828 ** certtool: Use inet_pton for parsing IPv6 addresses.
3830 ** Major changes compared to the v2.4 branch:
3832 *** Added API to replace and update the crypto backend.
3834 *** certtool: can add several subject alternative names via template file.
3836 *** opencdk: Parse (but not decrypt) encrypted secret keys.
3838 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
3839 either set or append alternative names. It can also handle binary structures
3840 such as IP addresses.
3842 *** libgnutls: New function to set minimum acceptable SRP bits.
3843 The function is gnutls_srp_set_prime_bits.
3845 *** libgnutls: Add interface to deal with public key and signature algorithms.
3846 The functions are called gnutls_pk_list, gnutls_pk_get_id,
3847 gnutls_sign_list, and gnutls_sign_get_id.
3849 *** libgnutls: New interfaces to get name of public key and signing algorithms.
3850 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
3852 *** libgnutls: New API to get a string corresponding to a error symbol.
3853 The function is gnutls_strerror_name.
3855 *** libgnutls: New API to set the public parameters in a certificate request
3856 *** from a private key.
3857 The function is gnutls_x509_crq_set_key_rsa_raw.
3859 *** libgnutls: New API to set a callback to extract TLS Finished data.
3860 The function to register is gnutls_session_set_finished_function and
3861 it takes a callback of the gnutls_finished_callback_func type.
3863 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
3865 *** libgnutls: New interface to register a new TLS extension handler.
3866 The new function gnutls_ext_register can be used to register handlers
3867 for specific TLS extension types. The callback functions have the new
3868 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
3869 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
3872 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
3873 The function is gnutls_register_md5_handler. When libgcrypt is in
3874 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
3877 *** API/ABI changes in GnuTLS 2.6
3878 No functions have been removed or modified. The library should be
3879 fully backwards compatible on both the source and binary level.
3881 A new header file <gnutls/crypto.h> have been added. It contains
3882 definitions related to replacing the internal crypto functionality.
3883 All definitions and the header itself is experimental but supported.
3885 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
3886 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
3887 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
3889 The following functions have been added to libgnutls:
3893 gnutls_crypto_bigint_register2
3894 gnutls_crypto_cipher_register2
3895 gnutls_crypto_digest_register2
3896 gnutls_crypto_mac_register2

3929 Report and patch by Jonathan Manktelow.
3931 ** libgnutls: crypto.h gnutls_pk_params_st changes allocation strategy.
3932 The parameters are now allocated in the structure itself.
3934 ** doc: Texinfo HTML manual uses a stylesheet to improve readability.
3936 ** tests: Scripts now use EXEEXT properly.
3937 Modern libtool doesn't create wrapper script, so the self tests need
3938 to invoke certtool.exe under MinGW32+Wine.
3940 ** Uses autoconf 2.63, automake 1.10.1, libtool 2.2.6a.
3941 Automake warnings are now also enabled.
3943 ** API and ABI modifications:
3944 gnutls_pk_params_st: MODIFIED
3946 * Version 2.5.8 (released 2008-09-21)
3948 ** certtool: updated so it can add several subject alternative names using
3951 ** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
3952 either set or append alternative names. It can also handle binary structures
3953 such as IP addresses.
3955 ** libgnutls: Fix crash in hashing code when using non-libgcrypt handlers.
3957 ** libgnutls: New function to set minimum acceptable SRP bits.
3958 The function is gnutls_srp_set_prime_bits. Tiny patch by Kevin Quick
3959 <quick@sparq.org> in <https://savannah.gnu.org/support/index.php?106454>.
3961 ** libgnutls: Check for overflows in gnutls_calloc and gnutls_secure_calloc.

4031 * Version 2.5.5 (released 2008-08-29)
4033 ** libgnutls: New API to get a string corresponding to a error symbol.
4034 The function is gnutls_strerror_name.
4036 ** libgnutls: Fix include paths so that building with internal libtasn1 works.
4037 Reported by "jth.net ApS" <info@jth.net>.
4039 ** libgnutls: Fix segmentation fault when generating private keys.
4040 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
4042 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
4043 The code has not worked since v0.9.0 and apparently nobody has missed
4044 it, so we decided to remove the code rather than fix it. If you have
4045 old certificate chains stored in PKCS#7 format, you can convert them
4046 to a list of PEM certificates by using 'certtool --p7-info'. Reported
4047 by Christian Grothoff <christian@grothoff.org>.
4049 ** opencdk: Parse (but not decrypt) encrypted secret keys.
4050 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
4052 ** libgnutls: Fix many warnings.
4054 ** Included copy of libtasn1 is upgraded to version 1.5.
4056 ** Add French translation, thanks to Nicolas Provost.
4058 ** API and ABI modifications:
4059 gnutls_strerror_name: ADDED
4061 * Version 2.5.4 (released 2008-08-19)
4063 ** Fix secure memory initialization of libgcrypt.
4064 Reported by Joe Orton <joe@manyfish.co.uk> in
4065 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2992>.
4068 Reference to NIST SP 800-57 in the manual on key size recommendations.
4069 Added 'Since:' tags to new APIs for gtk-doc.
4071 ** API and ABI modifications:
4072 No changes since last version.
4074 * Version 2.5.3 (released 2008-08-14)
4076 ** libgnutls: New API to set the public parameters in a certificate request
4077 ** from a private key.
4078 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
4079 discussion with "Zach C." <fxchip@gmail.com>.
4081 ** libgnutls: New API to set a callback to extract TLS Finished data.
4082 The function to register is gnutls_session_set_finished_function and
4083 it takes a callback of the gnutls_finished_callback_func type.
4085 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
4086 Reported in <https://savannah.gnu.org/support/?106453>.
4088 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
4089 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
4090 names are mapped to the new names in compat.h. These mappings will
4091 likely be removed more quickly than other mappings in that file due to
4092 the namespace violation.
4094 ** libgnutlsxx: Make it build when SRP is disabled.
4096 ** doc: Add doxygen files in doc/doxygen/.
4098 ** API and ABI modifications:

4103 GNUTLS_RANDOM_SIZE: ADDED
4104 TLS_MASTER_SIZE: DEPRECATED
4105 TLS_RANDOM_SIZE: DEPRECATED
4107 * Version 2.5.2 (released 2008-07-08)
4109 ** libgnutls: Fix bug in gnutls_dh_params_generate2.
4110 The prime and generator was swapped.
4112 ** libgnutls: New interface to register a new TLS extension handler.
4113 The new function gnutls_ext_register can be used to register handlers
4114 for specific TLS extension types. The callback functions have the new
4115 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
4116 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
4119 ** Move more code for TLS/IA extension from libgnutls to libgnutls-extra.
4120 This was made possible by using the new gnutls_ext_register interface.
4121 The TLS/IA functionality has only been supported through the
4122 libgnutls-extra library, so it makes sense for the code to belong
4125 ** API and ABI modifications:
4126 gnutls_ext_recv_func: ADDED
4127 gnutls_ext_send_func: ADDED
4128 gnutls_ext_parse_type_t: ADDED
4129 gnutls_ext_register: ADDED
4131 * Version 2.5.1 (released 2008-07-02)
4135 ** API and ABI modifications:
4136 No changes since last version.
4138 * Version 2.5.0 (released 2008-07-02)
4140 ** Port fixes from v2.4.1 release, see below.
4142 ** Added API to replace and update the crypto backend.
4143 The header gnutls/crypto.h is now officially supported, and declares
4146 ** Rewritten opencdk crypto backend, to use the gnutls internal one.
4148 ** Update gnulib and translations.
4149 The gnulib gc crypto code has been removed since it was never finished
4150 and is no longer even used. An internal non-libgcrypt crypto
4151 implementation may be added in the future, but we'll decide that later
4154 ** API and ABI modifications:
4155 gnutls_crypto_bigint_register2: ADDED.

4165 * Version 2.4.3 (released 2009-02-06)
4167 ** libgnutls: Accept chains where intermediary certs are trusted.
4168 Before GnuTLS needed to validate the entire chain back to a
4169 self-signed certificate. GnuTLS will now stop looking when it has
4170 found an intermediary trusted certificate. The new behaviour is
4171 useful when chains, for example, contains a top-level CA, an
4172 intermediary CA signed using RSA-MD5, and an end-entity certificate.
4173 To avoid chain validation errors due to the RSA-MD5 cert, you can
4174 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
4175 The signature on trusted certificates are not checked, so the chain
4176 has a chance to validate correctly. Reported by "Douglas E. Engert"
4177 <deengert@anl.gov> in
4178 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
4180 ** libgnutls: Permit V1 Certificate Authorities properly.
4181 Before they were mistakenly rejected even though
4182 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or

4274 ** API and ABI modifications:
4275 No changes since last version.
4277 * Version 2.4.0 (released 2008-06-19)
4279 ** Major changes compared to the v2.2 branch:
4281 *** The OpenPGP sub-system has been improved and now supports subkeys.
4283 *** The PSK sub-system has been improved and now supports password
4284 *** derivation and PSK identity hints.
4285 The password derivation algorithms support is documented in
4286 draft-ietf-netconf-tls-02.txt.
4288 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
4289 This aligns terminology with OpenPGP, which doesn't use DER encoding.
4290 The old parameters will continue to work for some time.
4292 *** Certtool now confirm passwords and changes permissions of private key files.
4294 *** The default handshake size limit has been increased to 48kb.
4295 It appears as if some valid handshakes are large due to sending many
4296 CA certificates. (The earlier limit was 16kb.)
4298 *** LZO compression is now disabled by default.
4299 The main reason is that LZO compression in TLS is not standardized,
4300 but license compatiblity issues with minilzo triggered us to make this
4303 *** Improvements for cross-compilation to Windows and OpenWRT.
4305 *** The look of the GTK-DOC manual has been improved.
4306 Major developer visible changes compared to the v2.2 branch:
4308 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
4310 *** New APIs to access the raw X.509 Subject and Issuer DN's and
4311 *** elements from the certificate credentials structure.
4312 Thanks to Joe Orton.
4314 *** New APIs to improve working with username/passwords and PSK.
4316 *** Names of constants to affect certificate printing changed.
4317 The constants are used for OpenPGP too, which the names didn't
4318 reflect, so the following name change has been made:
4321 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
4322 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
4323 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
4325 The old names will be mapped to the new names for some time.
4327 *** The function gnutls_openpgp_privkey_get_id has been renamed to
4328 *** gnutls_openpgp_privkey_get_key_id.
4329 A compatibility mapping exists to avoid breaking API backwards
4332 *** Replaced all uses of alloca with malloc and free.
4334 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
4335 We have been unable to find a documented rationale for this practice.
4337 *** Of course, many smaller fixes have been made, see the ChangeLog file.
4339 *** API/ABI changes in GnuTLS 2.4
4340 All OpenPGP related functions have been moved from libgnutls-extra to
4341 libgnutls, and several new functions have been added (see below).
4342 Before making the release, we discussed whether moving functions from
4343 libgnutls-extra to libgnutls would require us to increment the ABI
4344 version, but the general opinion was that this would not be required.
4345 All older functions continue to work the same. We are open to the
4346 possibility that this decision will lead to problem on some platform,
4347 and if it turns out that the Right Thing should have been to increment
4348 the shared library version, we would need to release an update within
4349 the 2.4.x branch that increments the shared library version.
4351 This release adds the following functions:
4353 gnutls_psk_client_get_hint
4354 gnutls_psk_set_server_credentials_hint
4355 gnutls_psk_netconf_derive_key
4357 Used to get/set the PSK identity hint, and derive PSK keys from
4358 passwords a'la netconf.
4360 gnutls_x509_dn_deinit
4361 gnutls_x509_dn_export
4362 gnutls_x509_dn_import
4365 Used to handle X.509 Certificate DN's directly.
4369 Converts a data buffer to hex. Useful for handling PSK/SRP shared
4372 gnutls_certificate_get_x509_cas
4373 gnutls_certificate_get_x509_crls
4374 gnutls_certificate_get_openpgp_keyring
4376 Functions for direct access to credential elements.
4378 gnutls_openpgp_crt_get_auth_subkey
4379 gnutls_openpgp_crt_get_key_id
4380 gnutls_openpgp_crt_get_pk_dsa_raw
4381 gnutls_openpgp_crt_get_pk_rsa_raw

4399 gnutls_openpgp_privkey_export
4400 gnutls_openpgp_privkey_export_dsa_raw
4401 gnutls_openpgp_privkey_export_rsa_raw

4415 gnutls_openpgp_privkey_get_subkey_pk_algorithm
4416 gnutls_openpgp_privkey_get_subkey_revoked_status
4417 gnutls_openpgp_privkey_set_preferred_key_id
4419 New OpenPGP related functions.
4421 The function gnutls_openpgp_crt_get_key_id is the same as the old
4422 from gnutls_openpgp_crt_get_id, see above.
4424 The release also adds a new header file 'gnutls/crypto.h', however it
4425 is currently not used.
4427 ** libgnutls [OpenPGP]: New APIs to retrieve fingerprint from OpenPGP subkeys.
4428 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
4430 ** API and ABI modifications:
4431 gnutls_openpgp_crt_get_subkey_fingerprint: ADDED.
4432 gnutls_openpgp_privkey_get_subkey_fingerprint: ADDED.
4434 * Version 2.3.15 (released 2008-06-15)
4436 ** Disable the openpgp-certs self-tests.
4437 It results in failure under Wine and doesn't work on Debian buildds.
4439 ** API and ABI modifications:
4440 No changes since last version.
4442 * Version 2.3.14 (released 2008-06-11)
4444 ** libgnutls [OpenPGP]: Changed OpenPGP verification behaviour.
4445 An OpenPGP certificate is now only considered verified if all the user
4448 ** Examples: Make C++ example compile.
4449 Earlier it may have failed with an unresolved reference to strlen.
4451 ** Documentation: Doc fix for gnutls_x509_crt_get_extension_oid.
4452 Reported by Sam Varshavchik <mrsam@courier-mta.com>.
4454 ** API and ABI modifications:
4455 No changes since last version.
4457 * Version 2.3.13 (released 2008-06-07)
4459 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
4461 ** doc/: Add psktool to info index. Some minor cleanups.
4463 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
4465 ** tests/: Added libgcrypt.supp which can be used with valgrind.
4466 The file suppresses the known libgcrypt memory leaks, so they aren't
4467 printed when you run valgrind on the gnutls self-tests. Use it as
4468 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add
4469 '--suppressions=/home/you/src/gnutls/tests/libgcrypt.supp' to your
4472 ** tests/: Reduce amount of debugging output by default.
4473 Use --verbose for each test to get the full output.
4475 ** tests/: Fix memory leaks in several self-tests.
4476 None of the self tests should be leaking memory when running valgrind
4477 or similar tools. (Known exceptions are dhepskself, pskself, and
4478 set_pkcs12_cred, which appear likely to be due to memory leaks in the
4481 ** API and ABI modifications:
4482 No changes since last version.
4484 * Version 2.3.12 (released 2008-06-04)
4486 ** Merge gnutls_with_netconf branch.
4488 *** libgnutls [PSK]: New API to retrieve PSK identity hint in client.
4489 The function is gnutls_psk_client_get_hint.
4491 *** libgnutls [PSK]: New API to set PSK identity hint in server.
4492 The function is gnutls_psk_set_server_credentials_hint.
4494 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
4495 In the client, the message is parsed and the application can use
4496 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
4497 message is sent if the application has specified a PSK identity hint
4498 using gnutls_psk_set_server_credentials_hint.
4500 *** libgnutls [PSK]: Support Netconf PSK key derivation.
4501 The function gnutls_psk_netconf_derive_key supports the PSK key
4502 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
4505 *** psktool: Support new --netconf-hint to generate PSK key from password.
4506 Uses the Netconf algorithm to derive PSK key from password.
4508 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
4510 *** gnutls-cli: Always support PSK modes, through a callback.
4511 The callback will derive a PSK key using Netconf algorithm. It will
4512 print the PSK identity hint to help the user.
4514 *** New PSK example client and server.
4515 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
4517 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.
4518 The code didn't work properly on platforms where 'char' is unsigned,
4519 when you set version 0. Reported by Laurence Withers
4520 <l@lwithers.me.uk> in
4521 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2825>.
4523 ** libgnutls-openssl: added RAND_pseudo_bytes API.
4524 Patch from Robert Millan <rmh@aybabtu.com>.
4526 ** API and ABI modifications:
4527 RAND_pseudo_bytes: ADDED to libgnutls-openssl.
4528 gnutls_psk_client_get_hint: ADDED.
4529 gnutls_psk_set_server_credentials_hint: ADDED.
4530 gnutls_psk_netconf_derive_key: ADDED
4532 * Version 2.3.11 (released 2008-05-20)
4534 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
4535 The flaw would result in incorrectly terminated sessions with the
4536 error "Decryption has failed" when the server sends a small packet
4537 (typically when the session is closed). Reported by Andreas Metzler
4538 <ametzler@downhill.at.eu.org> in
4539 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
4541 ** Don't use gnulib headers when building C++ library.
4542 Fixes builds under Windows.
4544 ** Make umask a requirement.
4545 We don't know of any system that lacks it, even GNU CoreUtils use it
4548 ** Update gnulib files.
4549 Fixes a problem where it pulled in a replacement for memcmp under
4550 MinGW, which caused the C++ example to fail to build.
4552 ** API and ABI modifications:
4553 No changes since last version.
4555 * Version 2.3.10 (released 2008-05-19)
4557 ** Added wide wildcard hostname matching.
4558 Tiny patch by Jean-Philippe Garcia Ballester.
4560 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
4561 Thanks to CERT-FI for finding the bugs and providing detailed reports,
4562 which allowed the bugs to be reproduced and fixed easily. Patches
4563 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
4564 with more details about these vulnerabilities will be added to
4565 <http://www.gnu.org/software/gnutls/security.html>
4567 *** [GNUTLS-SA-2008-1-1]
4568 *** libgnutls: Fix crash when sending invalid server name.
4569 The crash can be triggered remotely before authentication, which can
4570 lead to a Daniel of Service attack to disable the server. The bug
4571 cause gnutls to store more session resumption data than what was
4572 allocated for, thus overwriting unallocated memory.
4574 *** [GNUTLS-SA-2008-1-2]
4575 *** libgnutls: Fix crash when sending repeated client hellos.
4576 The crash can be triggered remotely before authentication, which can
4577 lead to a Daniel of Service attack to disable the server. The bug
4578 triggers a null-pointer dereference.
4580 *** [GNUTLS-SA-2008-1-3]
4581 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
4582 The crash can be triggered remotely before authentication, which can
4583 lead to a Daniel of Service attack to disable the server. The bug
4584 cause gnutls to read memory beyond the end of the received record.
4586 ** libgnutlsxx: Updated API according to patches from Eduardo
4587 Villanueva Che (discussion at
4588 <http://lists.gnu.org/archive/html/gnutls-devel/2007-02/msg00017.html>)
4590 ** Use umask to restrict permissions to owner before creating a file.
4592 ** API and ABI modifications:
4593 No changes since last version.
4595 * Version 2.3.9 (released 2008-05-16)
4597 ** libgnutls: Fix build failures if SRP/OpenPGP is disabled.
4598 Based on report and tiny patches from
4599 <jared.jennings.ctr@eglin.af.mil>, see
4600 <https://savannah.gnu.org/support/index.php?106342>.
4602 ** libgnutls: Translation fixes.
4604 ** gnutls-cli: Fix so that PSK authentication works.
4605 Also improve manual to give example for gnutls-cli PSK authentication.
4607 ** certtool: Encrypting a private key now require a confirmed password.
4608 Before './certtool -k -8' would merely ask for a password once.
4609 Reported by Daniel 'NebuchadnezzaR' Dehennin
4610 <nebuchadnezzar@asgardr.info> see
4611 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
4613 ** certtool: When writing private keys to files, change permissions of file.
4614 Now the file which the private key is saved to is chmod'ed 0600.
4615 Reported by martin f krafft <madduck@debian.org> see
4616 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
4618 ** guile: Fix -fgnu89-inline test.
4620 ** Removed --enable-profile-mode.
4621 The code linked gnutls with the libfc project (Function Check) which
4622 appears to have been stalled since around 2002.
4624 ** Clean up header file checks by ./configure.
4626 ** Update of gnulib files.
4628 ** API and ABI modifications:
4629 No changes since last version.
4631 * Version 2.3.8 (released 2008-04-29)
4633 ** libgnutls: Increase default handshake packet size limit to 48kb.
4634 The old limit was 16kb and some servers send huge list of trusted CAs,
4635 thus running into the limit. FYI, applications can further increase
4636 this limit using gnutls_handshake_set_max_packet_length. Thanks to
4637 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
4638 <marc@mclemente.net> for reporting and providing test servers.
4640 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
4641 Returned when the handshake data size is too large. Before
4642 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
4645 ** libgnutls: Hide definitions in crypto.h.
4646 We have decided that the APIs defined in crypto.h are not stable
4647 enough for v2.4, so don't use any of those functions.
4649 ** gnutls-cli: exit when hostname doesn't match certificate.
4650 Use --insecure to avoid hostname comparison.
4652 ** certtool: --inder and --outder replaced by --inraw and --outraw.
4653 The reason is to align terminology with OpenPGP, which doesn't use
4654 DER. The old parameters will continue to work for some time.
4656 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
4658 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
4660 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
4661 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
4662 vasprintf symbol from the libgcrypt library which caused problems.
4664 ** Update of gnulib files.
4666 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
4668 ** API and ABI modifications:
4669 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
4671 * Version 2.3.7 (released 2008-04-21)
4673 ** opencdk now properly sets the key usage bits into openpgp keys.
4675 ** gnutls-cli: Fix crash on TLS handshake failures.
4676 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
4677 This is similar to <http://bugs.debian.org/429183>.
4679 ** certtool: with --generate-request and newly generated keys, print the key.
4681 ** Build fixes for MinGW.
4682 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
4683 with -lws2_32 when needed. Use ASCII only isprint() when printing
4684 X.509 certificate information, to avoid non-ASCII but printable
4685 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
4688 ** Update internal copy of libtasn1 to version 1.4.
4690 ** API and ABI modifications:
4691 No changes since last version.
4693 * Version 2.3.6 (released 2008-04-17)
4695 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
4696 ** Improve documentation for gnutls_x509_crq_sign2.
4697 Based on report from "John Brooks" <aspecialj@gmail.com> in
4698 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
4700 ** tests/pathlen: run diff without parameters to improve portability.
4701 Based on HPUX build hints in
4702 <http://hpux.cs.utah.edu/hppd/cgi-bin/wwwtar?/hpux/Gnu/gnutls-2.3.4/gnutls-2.3.4-src-11.11.tar.gz+gnutls-2.3.4/HPUX.Install+text>.
4704 ** Don't use %e specifier with strftime, it doesn't work under Windows.
4705 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
4706 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
4708 ** Remove all uses of gnutls_alloca/gnutls_afree.
4709 Use normal gnutls_malloc instead. One reason is increased portability
4710 to Windows, the other is that several of the uses may be unsafe
4711 because the size of data allocated could be large. Reported by
4712 Massimo Gaspari <massimo.gaspari@alice.it> in
4713 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
4715 ** Build Guile code with -fgnu89-inline only when supported.
4716 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
4717 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
4719 ** Several GTK-DOC related fixes.
4721 ** Clean up OpenCDK related code.
4722 GnuTLS now requires its internal OpenCDK code rather than the external
4723 GPL library OpenCDK. Unfortunately, we don't have resources to
4724 maintain an external library (help welcome).
4726 ** API and ABI modifications:
4727 No changes since last version.
4729 * Version 2.3.5 (released 2008-04-14)
4731 ** Build fix for MinGW and --disable-shared.
4732 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
4733 <http://permalink.gmane.org/gmane.network.gnutls.general/1145>.
4735 ** Document how to generate CRLs.
4736 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
4738 ** Documented the --priority option to gnutls-cli and gnutls-serv.
4740 ** Several minor fixes in the OpenPGP interface.
4741 Thanks to Daniel Kahn Gillmor.
4743 ** Fix fopen file descriptor leak in PSK server code.
4744 Thanks to Laurence Withers <l@lwithers.me.uk>, see
4745 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
4747 ** Translations files not stored directly in git to avoid merge conflicts.
4749 ** New APIs to let applications replace the RNG used.
4750 Update all RNG callers in the code to use the new interface.
4752 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
4754 ** Update gnulib files.
4756 ** API and ABI modifications:
4757 gnutls_crypto_rnd_register: ADDED
4758 gnutls_rnd_level_t: ADDED
4759 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
4760 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
4761 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
4762 gnutls_crypto_rnd_st: ADDED
4763 GNUTLS_DIG_SHA224: ADDED
4764 GNUTLS_SIGN_RSA_SHA224: ADDED
4765 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
4767 * Version 2.3.4 (released 2008-03-19)
4769 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
4770 They weren't renamed in the public header file.
4772 ** Added functions to register a cipher/mac/digest. This allows to
4773 override the included ones.
4775 ** Fix a bunch of compiler warnings.
4777 ** API and ABI modifications:
4778 gnutls_crypto_cipher_st: ADDED
4779 gnutls_crypto_mac_st: ADDED
4780 gnutls_crypto_digest_st: ADDED
4781 gnutls_crypto_cipher_register: ADDED
4782 gnutls_crypto_mac_register: ADDED
4783 gnutls_crypto_digest_register: ADDED
4784 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
4786 * Version 2.3.3 (released 2008-03-10)
4788 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
4789 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
4791 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
4792 We could not find any modern justification for enabling these flags by
4793 default. If you know of some platform that needs one of the flags to
4794 work properly, please let us know. (Actually introduced in v2.3.0 but
4795 not documented until now.)
4797 ** Importing many CA certificates are now considerably faster.
4798 This affect gnutls_certificate_set_x509_trust_mem,
4799 gnutls_certificate_set_x509_trust, and
4800 gnutls_certificate_set_x509_trust_file. The complexity was reduced
4801 from O(2*n^2) to O(n). When adding 206 files containing 408
4802 certificates, using gnutls_certificate_set_x509_trust_file, the time
4803 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar FuĂŸ for code
4804 to trigger the problem. See also
4805 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
4807 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
4808 ** to be explicit that it takes zero terminated data.
4810 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.
4812 ** Documentation fixes for the GTK-DOC manual.
4814 ** Fix compilation error related to __FUNCTION__ on some systems.
4815 Reported by Tim Mooney, see
4816 <https://savannah.gnu.org/support/?106267>.
4818 ** Updated translations.
4820 ** Update gnulib files.
4822 ** API and ABI modifications:
4823 gnutls_hex2bin: MODIFIED, uses size_t instead of int for string length,
4824 and char* instead of void* for output buffer.
4826 * Version 2.3.2 (released 2008-02-26)
4828 ** Fix srcdir!=objdir failure in openpgpself test.
4830 ** Improved API documentation output from GTK-DOC.
4832 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
4834 ** Renamed gnutls_certificate_export_x509_cas and friends.
4835 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.
4837 ** Internal header files cleanup.
4839 ** API and ABI modifications:
4840 gnutls_certificate_export_x509_cas: RENAMED to gnutls_certificate_get_x509_cas
4841 gnutls_certificate_export_x509_crls: RENAMED to gnutls_certificate_get_x509_crls
4842 gnutls_certificate_export_openpgp_keyring: RENAMED to gnutls_certificate_get_openpgp_keyring
4843 gnutls_x509_dn_export: ADDED
4845 * Version 2.3.1 (released 2008-02-21)
4847 ** OpenPGP support merged into libgnutls and is now licensed under LGPL.
4848 The included copy of OpenCDK has been stripped down and re-licensed
4851 ** Cipher priority string handling now handle strings that starts with NULL.
4852 Thanks to Laurence Withers <l@lwithers.me.uk>.
4854 ** gnutls-cli: When -d is used, also prints RNG information from libgcrypt.
4856 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
4859 ** Increased the default certificate verification chain limits and allowed
4860 for checks without limitation.
4862 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
4863 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
4864 strings and return the proper size.
4866 ** Add section 'On Record Padding' to the manual.
4867 This collects all problems related to record padding with
4868 Nokia/Sony-Ericsson phones that we know about.
4870 ** Several improvements in the OpenPGP authentication.
4871 Now subkeys can be used for authentication, according to
4872 draft-mavrogiannopoulos-rfc5081bis-00.txt.
4874 ** certtool can print information on OpenPGP certificates and keys.
4876 ** Added gnutls_x509_dn_import/init/deinit() to access raw DER DN.
4879 ** Added gnutls_certificate_export_x509_cas and other functions to
4880 export elements from the certificate credentials structure. Based on
4881 suggestion from Joe Orton.
4884 Clarify that srp_base64 is not the same as normal base64.
4886 ** Fix non-portable use of brace expansion in makefiles.
4888 ** API and ABI modifications:
4889 gnutls_certificate_export_x509_cas: ADDED
4890 gnutls_certificate_export_x509_crls: ADDED
4891 gnutls_certificate_export_openpgp_keyring: ADDED
4892 gnutls_openpgp_keyid_t: ADDED, instead of hard-coded 'unsigned char[8]'.
4893 gnutls_openpgp_crt_get_key_id: ADDED, obsoletes gnutls_openpgp_crt_get_id.
4894 gnutls_openpgp_crt_get_revoked_status: ADDED
4895 gnutls_openpgp_crt_get_subkey_count: ADDED
4896 gnutls_openpgp_crt_get_subkey_idx: ADDED
4897 gnutls_openpgp_crt_get_subkey_revoked_status: ADDED
4898 gnutls_openpgp_crt_get_subkey_pk_algorithm: ADDED
4899 gnutls_openpgp_crt_get_subkey_creation_time: ADDED
4900 gnutls_openpgp_crt_get_subkey_expiration_time: ADDED
4901 gnutls_openpgp_crt_get_subkey_id: ADDED
4902 gnutls_openpgp_crt_get_subkey_usage: ADDED
4903 gnutls_openpgp_privkey_get_fingerprint: ADDED
4904 gnutls_openpgp_privkey_get_key_id: ADDED
4905 gnutls_openpgp_privkey_get_subkey_count: ADDED
4906 gnutls_openpgp_privkey_get_subkey_idx: ADDED
4907 gnutls_openpgp_privkey_get_subkey_revoked_status: ADDED
4908 gnutls_openpgp_privkey_get_revoked_status: ADDED
4909 gnutls_openpgp_privkey_get_subkey_pk_algorithm: ADDED
4910 gnutls_openpgp_privkey_get_subkey_expiration_time: ADDED
4911 gnutls_openpgp_privkey_get_subkey_id: ADDED
4912 gnutls_openpgp_privkey_get_subkey_creation_time: ADDED
4913 gnutls_openpgp_crt_get_subkey_pk_dsa_raw: ADDED
4914 gnutls_openpgp_crt_get_subkey_pk_rsa_raw: ADDED
4915 gnutls_openpgp_crt_get_pk_dsa_raw: ADDED
4916 gnutls_openpgp_crt_get_pk_rsa_raw: ADDED
4917 gnutls_openpgp_privkey_export_subkey_dsa_raw: ADDED
4918 gnutls_openpgp_privkey_export_subkey_rsa_raw: ADDED
4919 gnutls_openpgp_privkey_export_dsa_raw: ADDED
4920 gnutls_openpgp_privkey_export_rsa_raw: ADDED
4921 gnutls_openpgp_privkey_export: ADDED

4927 GNUTLS_E_OPENPGP_SUBKEY_ERROR: ADDED
4928 gnutls_hex2bin: ADDED
4929 GNUTLS_CRT_PRINT_FULL: ADDED, same as old GNUTLS_X509_CRT_FULL.
4930 GNUTLS_CRT_PRINT_ONELINE: ADDED, same as old GNUTLS_X509_CRT_ONELINE.
4931 GNUTLS_CRT_PRINT_UNSIGNED_FULL: ADDED, same as
4932 old GNUTLS_X509_CRT_UNSIGNED_FULL.
4934 * Version 2.3.0 (released 2008-01-08)
4936 ** LZO compression is now disabled by default.
4937 The reason is that LZO compression is not standardized in TLS. If you
4938 wish to experiment with it, you will have to supply --with-lzo when
4939 invoking ./configure. The internal copy of minilzo is no longer
4940 included with GnuTLS, so you will need to install liblzo or liblzo2 on
4941 your system to have --with-lzo to be effective.
4943 ** More than one server name field is now sent to the server properly.
4944 Thanks to mark.phillips@virgin.net.
4946 ** Fixes the post_client_hello_function(). The extensions are now parsed
4947 in a callback friendly way.
4949 ** Fix for certificate selection in servers with certificate callbacks.
4951 ** Updated translations.
4953 ** Update gnulib files.
4955 ** API and ABI modifications:
4956 No changes since last version.
4958 * Version 2.2.5 (released 2008-05-19)
4960 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
4961 The flaw would result in incorrectly terminated sessions with the
4962 error "Decryption has failed" when the server sends a small packet
4963 (typically when the session is closed). Reported by Andreas Metzler
4964 <ametzler@downhill.at.eu.org> in
4965 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
4967 ** API and ABI modifications:
4968 No changes since last version.
4970 * Version 2.2.4 (released 2008-05-19)
4972 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
4973 Thanks to CERT-FI for finding the bugs and providing detailed reports,
4974 which allowed the bugs to be reproduced and fixed easily. Patches
4975 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
4976 with more details about these vulnerabilities will be added to
4977 <http://www.gnu.org/software/gnutls/security.html>
4979 *** [GNUTLS-SA-2008-1-1]
4980 *** libgnutls: Fix crash when sending invalid server name.
4981 The crash can be triggered remotely before authentication, which can
4982 lead to a Daniel of Service attack to disable the server. The bug
4983 cause gnutls to store more session resumption data than what was
4984 allocated for, thus overwriting unallocated memory.
4986 *** [GNUTLS-SA-2008-1-2]
4987 *** libgnutls: Fix crash when sending repeated client hellos.
4988 The crash can be triggered remotely before authentication, which can
4989 lead to a Daniel of Service attack to disable the server. The bug
4990 triggers a null-pointer dereference.
4992 *** [GNUTLS-SA-2008-1-3]
4993 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
4994 The crash can be triggered remotely before authentication, which can
4995 lead to a Daniel of Service attack to disable the server. The bug
4996 cause gnutls to read memory beyond the end of the received record.
4998 ** API and ABI modifications:
4999 No changes since last version.
5001 * Version 2.2.3 (released 2008-05-06)
5003 ** Increase default handshake packet size limit to 48kb.
5004 The old limit was 16kb and some servers send huge list of trusted CAs,
5005 thus running into the limit. FYI, applications can further increase
5006 this limit using gnutls_handshake_set_max_packet_length. Thanks to
5007 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
5008 <marc@mclemente.net> for reporting and providing test servers.
5010 ** Fix compilation error related to __FUNCTION__ on some systems.
5011 Reported by Tim Mooney, see
5012 <https://savannah.gnu.org/support/?106267>.
5014 ** Documented the --priority option to gnutls-cli and gnutls-serv.
5016 ** Fix fopen file descriptor leak in PSK server code.
5017 Thanks to Laurence Withers <l@lwithers.me.uk>, see
5018 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
5020 ** Build Guile code with -fgnu89-inline only when supported.
5021 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
5022 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
5024 ** Make Camellia encryption work.
5025 Reported by Yoshisato YANAGISAWA <yanagisawa@csg.is.titech.ac.jp> in
5026 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2746>.
5028 ** API and ABI modifications:
5029 No changes since last version.
5031 * Version 2.2.2 (released 2008-02-21)
5033 ** Cipher priority string handling now handle strings that starts with NULL.
5034 Thanks to Laurence Withers <l@lwithers.me.uk>.
5036 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
5039 ** Increased the default certificate verification chain limits and allowed
5040 for checks without limitation.
5042 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
5043 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
5044 strings and return the proper size.
5046 ** API and ABI modifications:
5047 No changes since last version.
5049 * Version 2.2.1 (released 2008-01-17)
5051 ** Prevent linking libextra against previously installed libgnutls.
5052 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
5053 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
5055 ** Fixes the post_client_hello_function(). The extensions are now parsed
5056 in a callback friendly way.
5058 ** Fix for certificate selection in servers with certificate callbacks.
5060 ** API and ABI modifications:
5061 No changes since last version.
5063 * Version 2.2.0 (released 2007-12-14)
5065 ** Update internal copy of libtasn1 to version 1.2.
5067 ** Certtool --verify-chain now handle inputs larger than 64kb.
5068 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
5069 recent versions of libgcrypt. The problem was that Wine with the
5070 libgcrypt RNG generates huge amounts of debugging output.
5072 ** Translation updates.
5073 Added Dutch translation. Updated Polish and Swedish translation.
5075 ** Major changes compared to the v2.0 branch:
5077 *** SRP support aligned with newly published RFC 5054.
5079 *** OpenPGP support aligned with newly published RFC 5081.
5081 *** Support for DSA2 keys.
5083 *** Support for Camellia cipher.
5085 *** Support for Opaque PRF Input extension.
5087 *** PKCS#8 parser now handle DSA keys.
5089 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
5090 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
5091 versions, such as 2.01 which is included with GnuTLS, is available
5092 under GPLv2 or later. If this incompatibility causes problems, we
5093 recommend you to disable LZO using --without-lzo. LZO compression is
5094 not a standard TLS compression algorithm, so the impact should be
5097 *** Functions for disabling record protocol padding.
5098 Works around bugs on Nokia/Ericsson phones.
5100 *** New functions gnutls_priority_set() for setting cipher priorities easily.
5101 Priorities like "COMPAT" also enables other work arounds, such as
5104 *** Other minor improvements and bug fixes.
5106 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
5107 To adapt to changes in the TLS extension specifications for OpenPGP
5108 and SRP, the GnuTLS API had to be modified. This means breaking the
5109 API and ABI backwards compatibility. That is something we try to
5110 avoid unless it is necessary. We decided to also remove the already
5111 deprecated stub functions for X.509 to XML conversion and TLS
5112 authorization (see below) when we had the opportunity.
5114 Generally, most applications does not need to be modified. Just
5115 re-compile them against the latest GnuTLS release, and it should work
5118 Applications that use the OpenPGP or SRP features needs to be
5119 modified. Below is a list of the modified APIs and discussion of what
5120 the minimal things you need to modify in your application to make it
5121 work with GnuTLS 2.2.
5123 Note that GnuTLS 2.2 also introduces new APIs -- such as
5124 gnutls_set_priority() that is superior to
5125 gnutls_set_default_priority() -- that you may want to start using.
5126 However, using those new APIs is not required to use GnuTLS 2.2 since
5127 the old functions continue are still supported. This text only
5128 discuss what you minimally have to modify.
5130 *** XML related changes
5131 The function `gnutls_x509_crt_to_xml' has been removed. It has been
5132 deprecated and only returned an error code since GnuTLS version
5133 1.2.11. Nobody has complained, so users doesn't seem to miss the
5134 functionality. We don't know of any other library to convert X.509
5135 certificates into XML format, but we decided (long ago) that GnuTLS
5136 isn't the right place for this kind of functionality. If you want
5137 help to find some other library to use here, please explain and
5138 discuss your use case on help-gnutls@gnu.org.
5140 *** TLS Authorization related changes
5141 Everything related to TLS authorizations have been removed, they were
5142 only stub functions that returned an error code:
5144 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
5145 gnutls_authz_data_format_type_t
5146 gnutls_authz_recv_callback_func
5147 gnutls_authz_send_callback_func
5149 gnutls_authz_send_x509_attr_cert
5150 gnutls_authz_send_saml_assertion
5151 gnutls_authz_send_x509_attr_cert_url
5152 gnutls_authz_send_saml_assertion_url
5154 *** SRP related changes
5155 The callback gnutls_srp_client_credentials_function has a new
5156 prototype, and its semantic has changed. You need to rewrite the
5157 callback, see the updated function documentation and SRP example code
5158 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
5161 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
5162 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
5163 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
5164 used. There are #define's to map the old names to the new. You may
5165 run into problems if you have a switch-case with cases for both SRP
5166 alerts, since they are now mapped to the same value. The solution is
5167 to drop the SRP alerts from such switch cases, as they are now
5168 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
5170 *** OpenPGP related changes
5171 The function `gnutls_certificate_set_openpgp_keyserver' have been
5172 removed. There is no replacement functionality inside GnuTLS. If you
5173 need keyserver functionality, consider using the GnuPG tools.
5175 All functions, types, and error codes related to OpenPGP trustdb
5176 format have been removed. The trustdb format is a non-standard
5177 GnuPG-specific format, and we recommend you to use key rings instead.
5178 The following have been removed:
5180 gnutls_certificate_set_openpgp_trustdb
5181 gnutls_openpgp_trustdb_init
5182 gnutls_openpgp_trustdb_deinit
5183 gnutls_openpgp_trustdb_import
5184 gnutls_openpgp_key_verify_trustdb
5185 gnutls_openpgp_trustdb_t
5186 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
5188 The following functions has an added parameter of the (new) type
5189 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
5190 (binary or base64). The functions are:
5191 gnutls_certificate_set_openpgp_key_file
5192 gnutls_certificate_set_openpgp_key_mem
5193 gnutls_certificate_set_openpgp_keyring_mem
5194 gnutls_certificate_set_openpgp_keyring_file
5196 To improve terminology and align with the X.509 interface, some
5197 functions have been renamed. Compatibility mappings exists. The old
5198 and new names of the affected functions and types are:
5201 gnutls_openpgp_key_t gnutls_openpgp_crt_t

5221 ** API and ABI modifications:
5222 No changes since last version.
5224 * Version 2.1.8 (released 2007-12-10)
5226 ** The GPL version has been changed from version 2 to version 3.
5227 This affects the self-tests, command-line tools, the libgnutls-extra
5228 library, the relevant guile parts, and the build environment.
5230 ** Added gnutls_x509_crt_get_subject_alt_name2().
5232 ** Corrected a segfault when setting an empty gnutls_priority_t
5233 at gnutls_priority_set().
5235 ** Use gettext 0.17 which updates m4/lib-*.m4 macros.
5236 Fixes a problem with spurious -L/usr/lib additions.
5238 ** API and ABI modifications:
5239 gnutls_x509_crt_get_subject_alt_name2: ADD.
5241 * Version 2.1.7 (released 2007-11-29)
5243 ** PKCS #8 parser can now encode/decode DSA keys.
5245 ** Updated gnutls_set_default_priority2() now renamed to
5246 gnutls_priority_set() and gnutls_priority_set_direct() which
5247 accept a string to indicate preferences of ciphersuite parameters.
5249 ** gnutls-cli and gnutls-serv now have a --priority option to set
5250 the priority string.
5252 ** The gnutls_*_convert_priority() functions were deprecated by
5253 the gnutls_priority_set() and gnutls_priority_set_direct().
5255 ** Internal copy of OpenCDK upgraded to version 0.6.6.
5257 ** API and ABI modifications:
5258 gnutls_priority_init: ADD.
5259 gnutls_priority_deinit: ADD.
5260 gnutls_priority_set: ADD.
5261 gnutls_priority_set_direct: ADD.

5269 gnutls_set_default_priority: UNDEPRECATED
5270 gnutls_set_default_priority_export: UNDEPRECATED
5272 ** Undocumented API and ABI modifications earlier in the 2.1.x series:
5273 GNUTLS_CIPHER_UNKNOWN: ADD.
5274 GNUTLS_CIPHER_CAMELLIA_128_CBC: ADD.
5275 GNUTLS_CIPHER_CAMELLIA_256_CBC: ADD.

5277 GNUTLS_COMP_UNKNOWN: ADD.
5278 GNUTLS_CRT_UNKNOWN: ADD.
5279 gnutls_mac_get_id: ADD.

5286 gnutls_certificate_send_x509_rdn_sequence: ADD prototype to gnutls.h.in.
5288 * Version 2.1.6 (released 2007-11-15)
5290 ** Corrected bug in decompression of expanded compression data.
5292 ** Added the --to-p8 option to certtool to convert private keys
5295 ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code.
5297 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
5300 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
5301 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
5302 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
5303 documented. This caused some problems (e.g., debian #450854). To
5304 avoid backwards compatibility problems, this release revert this
5305 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
5306 done in GnuTLS 2.0.x and earlier, and add a new error code
5307 GNUTLS_E_UNKNOWN_ALGORITHM.
5309 ** Fixes several gtk-doc warnings.
5311 ** API and ABI modifications:
5312 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
5313 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
5314 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
5316 * Version 2.1.5 (released 2007-11-01)
5318 ** Fix PKCS#3 parameter export problem.
5320 ** Improve certtool queries, they now print the default value.
5324 ** Update gnulib files.
5326 ** API and ABI modifications:
5327 No changes since last version.
5329 * Version 2.1.4 (released 2007-10-27)
5331 ** Added the --v1 option to certtool, to allow generating X.509
5332 version 1 certificates.
5334 ** certtool: Add option --disable-quick-random to enable the old behaviour
5335 of using /dev/random to generate keys.
5337 ** Added priority functions that accept strings.
5339 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
5340 priorities preferences.
5342 ** Added gnutls_record_disable_padding() to allow servers talking to
5343 buggy clients that complain if the TLS 1.0 record protocol padding is
5346 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
5347 all supported compatibility options (like disabling padding).
5349 ** The gnutls_certificate_set_openpgp_* functions were modified to include
5350 the format. This makes the interface consistent with the x509 functions.
5352 ** Internal copy of OpenCDK upgraded to version 0.6.5.
5354 ** Update gnulib files.

5391 * Version 2.1.3 (released 2007-10-17)
5393 ** TLS authorization support removed.
5394 This technique may be patented in the future, and it is not of crucial
5395 importance for the Internet community. After deliberation we have
5396 concluded that the best thing we can do in this situation is to
5397 encourage society not to adopt this technique. We have decided to
5398 lead the way with our own actions.
5400 ** Re-enabled the 256 bit ciphers in the default priorities.
5402 ** Corrected bugs in openpgp key verification using a keyring (both in

5415 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
5416 gnutls_supplemental_data_format_type_t enum type becomes empty.
5418 * Version 2.1.2 (released 2007-10-14)
5420 ** Removed all the trustdb code from openpgp authentication.
5421 We now use only the well-specified keyrings.
5423 ** The 256 bit ciphers are not enabled in the default priorities.
5425 ** Added support for DSA2 using libgcrypt 1.3.0.
5427 ** certtool: Fixed data corruption when using --outder.
5429 ** Removed all the xml related stubs and functions.
5431 ** Added capability to set a callback after the client hello is received
5432 by the server in order to adjust parameters before the handshake.
5434 ** SRP was corrected to adhere to the latest draft (published soon as RFC)
5436 ** Corrected bug which did not allow a server to run without supporting
5439 ** Updated the DN parser which now prints wrongly decoded values as hex
5442 ** certtool: Add option --quick-random.

5458 GNUTLS_A_UNKNOWN_SRP_USERNAME: DEPRECATED
5460 * Version 2.1.1 (released 2007-09-24)
5462 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
5463 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
5464 compiled with Camellia support. See the libgcrypt documentation on
5465 how to enable it. Unconditionally disable it using the configure
5466 option --disable-camellia. Fixes #1.
5468 ** Properly document in the NEWS file the API change in the last release.
5470 ** API and ABI modifications:
5471 No changes since last version.
5473 * Version 2.1.0 (released 2007-09-20)
5475 ** Support for draft-rescorla-tls-opaque-prf-input-00.txt.
5476 The support is disabled by default. Since no value has been allocated
5477 by the IANA for this extension yet, you will need to provide one
5478 yourself by invoking './configure --enable-opaque-prf-input=42'.
5481 ** Example code: Fix compilation flaw under MinGW.
5483 ** API and ABI modifications:
5484 gnutls_oprfi_callback_func: ADD, new typedef function prototype.
5485 gnutls_oprfi_enable_client: ADD, new function.
5486 gnutls_oprfi_enable_server: ADD, new function.

5515 * Version 2.0.2 (released 2007-10-17)
5517 ** TLS authorization support removed.
5518 This technique may be patented in the future, and it is not of crucial
5519 importance for the Internet community. After deliberation we have
5520 concluded that the best thing we can do in this situation is to
5521 encourage society not to adopt this technique. We have decided to
5522 lead the way with our own actions.
5524 ** certtool: Fixed data corruption when using --outder.
5526 ** Fix configure-time Guile detection.
5528 ** API and ABI modifications:
5529 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
5530 gnutls_supplemental_data_format_type_t enum type becomes empty.
5532 * Version 2.0.1 (released 2007-09-20)
5534 ** New directory doc/credentials/ with test credentials.
5535 This collects the test credentials from the web page and from src/.
5536 The script gnutls-http-serv has also been moved to that directory.
5538 ** Update SRP extension type and cipher suite with official IANA values.
5539 This breaks backwards compatibility with SRP in older versions of
5540 GnuTLS, but this is intentional to speed up the adoption of the
5541 official values. The old values we used were incorrect.
5543 ** Guile: Fix `x509-certificate-dn-oid'
5545 ** API and ABI modifications:
5546 No changes since last version.
5548 * Version 2.0.0 (released 2007-09-04)
5550 ** Included copy of Libtasn1 upgraded to version 1.1.
5552 ** Disable building of some examples if anonymous ciphers are disabled.
5554 ** Don't build examples for disabled features.
5556 ** API and ABI modifications:
5557 No changes since last version.
5559 * Version 1.7.19 (released 2007-08-27)
5561 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
5562 This solves connection problems in mutt, see
5563 <http://bugs.debian.org/439640>.
5565 ** Update gnulib files.
5566 In particular, the getpass module -- with its dependencies on getline,
5567 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
5568 library) directory to the gl/ directory (only used by the command line
5569 tools). The reason is that getpass is now only used by the
5570 command-line tools, and reducing the number of gnulib modules linked
5571 to the core library helps portability and reduces size.
5575 ** Disable building of PGP examples if PGP is disabled.
5577 ** Included copy of OpenCDK upgraded to version 0.6.4.
5579 ** API and ABI modifications:
5580 No changes since last version.
5582 * Version 1.7.18 (released 2007-08-16)
5584 ** Install images for the info manual.
5585 This has a side effect of renaming the images. See
5586 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
5587 discussions on the approach chosen.
5589 ** Fix pointer mix to variables of different size.
5590 Patch extracted from
5591 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
5593 ** Fix warnings during build.
5594 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
5596 ** API and ABI modifications:
5597 No changes since last version.
5599 * Version 1.7.17 (released 2007-08-15)
5601 ** New functions to perform external signing.
5602 Set the signing callback function (of the gnutls_sign_func prototype)
5603 using the gnutls_sign_callback_set function. In the callback, you may
5604 find the new functions gnutls_x509_privkey_sign_hash and
5605 gnutls_openpgp_privkey_sign_hash useful. A new function
5606 gnutls_sign_callback_get is also added, to retrieve the function
5607 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
5608 comments and testing.
5610 ** New self test of client and server authenticated X.509 TLS sessions.
5611 See tests/x509self.c and tests/x509signself.c. The latter also tests
5612 the new external signing callback interface.
5614 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
5615 These two actually describe the outer limits of a range of error codes
5616 reserved to the application. All of the errors are treated as fatal
5617 by the library (it has to since it doesn't know the semantics of the
5618 error codes). This can be useful in callbacks, to signal some
5619 application-specific error condition, which will usually eventually
5620 cause some gnutls API to return the same error code as the callback,
5621 which then can be inspected by the application. Note that error codes
5624 ** gnutls_set_default_priority now disable TLS 1.2 by default.
5625 The RFC is not released yet, and we're approaching a major release so
5626 let's not enable it just yet.
5628 ** Fix namespace so that gnutls_*_t is used consistently.
5629 Before, many places in the GnuTLS code used the old deprecated type
5630 names without the '_t' suffix.
5632 ** Build fixes for Guile code.
5633 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
5635 ** More documentation fixes.
5636 In particular, the section headings were modified for casing. By
5637 Ludovic Courtes <ludovic.courtes@laas.fr>.
5639 ** Updated Polish and Swedish translations.
5640 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
5641 <po@danielnylander.se>.
5643 ** API and ABI modifications:
5644 gnutls_sign_func: ADD, new type for sign callback.
5645 gnutls_sign_callback_set: ADD, new function to set sign callback.
5646 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
5647 gnutls_x509_privkey_sign_hash,
5648 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
5649 GNUTLS_E_APPLICATION_ERROR_MIN,
5650 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
5652 * Version 1.7.16 (released 2007-08-07)
5654 ** Fix sanity checks and return values in certificate selection.
5655 In some cases, GnuTLS omitted to report suitable error codes when no
5656 suitable certificate was found.
5658 ** Fix gnutls-cli starttls EOF on Mac OS X.
5659 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
5661 ** Documentation fixes.
5662 In particular, the section headings were modified for casing. By
5663 Ludovic Courtes <ludovic.courtes@laas.fr>.
5665 ** Update gnulib files.
5667 ** API and ABI modifications:
5668 No changes since last version.
5670 * Version 1.7.15 (released 2007-07-02)
5672 ** Fix self-tests key-id under mingw32.
5674 ** Test that the Guile header files are recent enough to work.
5675 Before we just tested that the command line tool 'guile' was recent
5676 enough, which may not be sufficient if you still have an old
5677 libguile.h header installed.
5679 ** Guile bindings are now installed under $prefix by default.
5680 Use --without-guile-site-dir to install it under $pkgdatadir/site/
5681 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
5682 Use --with-guile-site-dir=/your/own/path to specify the path manually.
5683 The default, --with-guile-site-dir, will install the Guile bindings
5684 under $datadir/guile/site. There is a new section 'Guile
5685 Preparations' in the manual that discuss these issues.
5687 ** Fix run-time library path ordering in linking the Guile bindings.
5689 ** Improved manual on downloading, installing, getting help, bug reports etc.
5690 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
5692 ** Add Malay message translations.

5771 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
5773 ** API and ABI modifications:
5774 No changes since last version.
5776 * Version 1.7.10 (released 2007-05-25)
5778 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
5779 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
5781 ** Update of gnulib files.
5783 ** GnuTLS is now developed in GIT instead of CVS.
5784 See <http://repo.or.cz/w/gnutls.git> for a public repository.
5786 ** API and ABI modifications:
5787 gnutls_x509_crt_get_raw_issuer_dn: ADD.
5788 gnutls_x509_crt_get_raw_dn: ADD.
5790 * Version 1.7.9 (released 2007-05-12)
5792 ** X.509 certificates are preferred over OpenPGP keys.
5793 This is a change in the semantics of gnutls_set_default_priority.
5795 ** The included copy of OpenCDK has been updated to 0.6.1.
5796 There has been some API changes in OpenCDK, and the GnuTLS layer have
5797 been modified as well. Note that while there are API/ABI incompatible
5798 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
5799 its API/ABI have not changed. From this version on, GnuTLS requires
5800 OpenCDK 0.6.0 or later.
5802 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
5804 ** Change certtool's default serial number from 0 to a time-based value.
5806 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
5807 Before, we remove the parameters field, which resulted in a slightly
5808 different DER encoding which in turn caused signature verification
5809 failures of GnuTLS-generated RSA certificates in some other
5810 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
5811 you read, this may or may not be correct, but our new behaviour appear
5812 to be consistent with other widely used implementations.
5814 ** Fix mem leaks in gnutls_x509_crt_print.
5816 ** API and ABI modifications:
5817 No changes since last version.
5819 * Version 1.7.8 (released 2007-04-16)
5821 ** Added examples for the authorization extension.
5822 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
5824 ** The examples only use gnutls_set_default_priority().
5825 The exception is when DH_ANON is needed.
5827 ** Improve gnutls_set_default_priority() priorities.
5828 The new approach is for it to try and negotiate all secure and
5829 standard mechanisms available. Currently, DH_ANON ciphersuites and
5830 LZO compressions are not enabled by default, because they are,
5831 respectively, insecure and non-standardized. Note that TLS 1.2 will
5832 not be enabled by default in non-experimental release until it has
5833 been approved by the IETF.
5835 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
5836 This means that to get DH_ANON and LZO compression, you'll need to
5837 specify that manually using '--kx anon' or '--comp lzo'.
5839 ** Minor fixes to the human display format of X.509 certificates.
5841 ** New APIs to extract Distinguished Name's from X.509 certificates.
5842 Based on patch from Howard Chu <hyc@symas.com>.
5844 ** Improved library searching for opencdk.
5845 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
5846 The deprecated opencdk.m4 is no longer used.
5848 ** New APIs to list supported algorithms in the library.
5849 The APIs are gnutls_cipher_list, gnutls_mac_list,
5850 gnutls_compression_list, gnutls_protocol_list,
5851 gnutls_certificate_type_list, gnutls_kx_list, and
5852 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
5854 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
5856 ** New configure option --disable-tls-authorization to disable tls-authz.
5858 ** Fix prototype for `gnutls_psk_set_client_credentials'.
5859 The last parameter was renamed from 'flags' to 'format' and the type
5860 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
5861 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
5864 ** Fix allocation in gnutls_certificate_set_openpgp_key.
5865 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
5867 ** API and ABI modifications:
5868 gnutls_x509_dn_t: ADD.
5869 gnutls_x509_ava_st: ADD.
5870 gnutls_x509_crt_get_subject,
5871 gnutls_x509_crt_get_issuer: ADD.
5872 gnutls_x509_dn_get_rdn_ava: ADD.
5873 gnutls_cipher_list: ADD.
5874 gnutls_mac_list: ADD.
5875 gnutls_compression_list: ADD.
5876 gnutls_protocol_list: ADD.
5877 gnutls_certificate_type_list: ADD.
5878 gnutls_kx_list: ADD.
5879 gnutls_cipher_suite_info: ADD.
5881 * Version 1.7.7 (released 2007-02-22)
5883 ** Support for supplemental handshake messages and authorization data.
5884 Supplemental data is described in RFC 4680 and the authorization
5885 extensions in draft-housley-tls-authz-extns-07.
5887 ** Support for authorization data in gnutls-cli and gnutls-serv.
5888 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
5890 ** Fix for gnutls_x509_crt_check_hostname.
5891 Before it would have reported that the certificate matched a hostname
5892 when it did not have any dNSName or any CN field. Report and tiny
5893 patch from "Richard W.M. Jones" <rjones@redhat.com>.
5895 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
5896 Tests regressions of the bug, and several other features.
5898 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
5899 Before there were no support for iPAddress SAN's during comparison.
5901 ** New API to print information about CRL's.
5902 The function is gnutls_x509_crl_print.
5904 ** New API to extract signature value from CRL's.
5905 The function is gnutls_x509_crl_get_signature.
5907 ** Support for directoryName Subject Alternative Name's.
5908 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
5909 string in the provided buffer.
5911 ** Internal improvements to certtool.
5912 It uses gnutls_x509_crl_print to print CRL information. It uses some
5913 more gnulib modules to simplify error handling.
5915 ** API and ABI modifications:
5916 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
5917 gnutls_supplemental_data_format_type_t: ADD.
5918 gnutls_authz_data_format_type_t: ADD.
5919 gnutls_supplemental_get_name: ADD.
5920 gnutls_authz_recv_callback_func,
5921 gnutls_authz_send_callback_func: ADD, callback prototypes.
5922 gnutls_authz_enable: ADD.
5923 gnutls_authz_send_x509_attr_cert,
5924 gnutls_authz_send_saml_assertion,
5925 gnutls_authz_send_x509_attr_cert_url,
5926 gnutls_authz_send_saml_assertion_url: ADD.
5927 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
5928 gnutls_x509_crl_print: ADD.
5929 gnutls_x509_crl_get_signature: ADD.
5931 * Version 1.7.6 (released 2007-02-12)
5933 ** Support for 'otherName' Subject Alternative Names.
5934 The existing API gnutls_x509_crt_get_subject_alt_name may now return
5935 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
5936 To find out the otherName OID (necessary for proper parsing of the
5937 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
5938 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
5939 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
5940 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
5942 ** Certtool can print otherName SAN values for certificates.
5943 For known otherName OIDs (currently only id-on-xmppAddr as defined by
5944 RFC 3920), it will also print the name.
5946 ** Fix TLS 1.2 RSA signing in servers.
5947 Before it used the old-style MD5+SHA1 signature, but the TLS
5948 signatures should be normal PKCS#1 signatures. FYI, we use and
5949 require that DigestInfo parameters are present and NULL for TLS 1.2.
5951 ** Add APIs to access X.509 extensions sequentially.
5952 The existing APIs gnutls_x509_crt_get_extension_oid() and
5953 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
5954 inspect the extensions in the order defined by the certificate.
5956 ** Add API to extract signature value from X.509 certificates.
5957 The function is gnutls_x509_crt_get_signature.
5959 ** Fix crash when generating proxy certificates in batch mode.
5960 If you don't specify a proxy policy in batch mode, it will use
5963 ** Add API to print information about X.509 certificates.
5964 The function is gnutls_x509_crt_print.
5966 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
5967 One consequence of this is that the output syntax has changed
5968 slightly. Some more fields are printed.
5972 ** API and ABI modifications:
5973 gnutls_x509_crt_print: ADD
5974 gnutls_certificate_print_formats_t: ADD, new enum.
5975 gnutls_x509_crt_get_signature: ADD.
5976 gnutls_x509_crt_get_extension_data: ADD.
5977 gnutls_x509_crt_get_extension_info: ADD.
5978 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
5979 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
5980 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
5982 * Version 1.7.5 (released 2007-02-06)
5984 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
5987 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
5989 ** Fix --list output for gnutls-cli and gnutls-serv.
5990 Mention TLS1.2, SHA512 etc.
5992 ** Manual contains new section on setting up a test HTTP server.
5993 A server set up following those descriptions are available online via
5994 <http://www.gnutls.org/server.html>.
5996 ** Update of gnulib files.
5998 ** API and ABI modifications:
5999 No changes since last version.
6001 * Version 1.7.4 (released 2007-02-05)
6003 ** Support for RSA signing using SHA-256/384/512.
6004 A new self test "sha2" tries to build a long X.509 certificate chain
6005 testing all new hashes.
6007 ** The gnutls-serv tool now use static DH parameters if none are supplied.
6009 ** Discuss proxy certificates in the manual.
6011 ** Improve bibliographical citations in the manual.
6013 ** Update of gnulib files.
6015 ** Fix certtool template handling of pathLenConstraints.
6016 It now defaults to -1 instead of 0, which causes the field to be
6017 missing unless the template specify it.
6019 ** API and ABI modifications:
6022 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
6025 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
6026 GNUTLS_SIGN_RSA_SHA256,
6027 GNUTLS_SIGN_RSA_SHA384,
6028 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
6030 * Version 1.7.3 (released 2007-02-01)
6032 ** New option to certtool: --generate-proxy.
6033 This will generate a Proxy Certificate from an end entity certificate.
6034 Proxy Certificates are documented in RFC 3820. You will need to
6035 specify the proxy certificate's private key with --load-privkey, the
6036 user certificate with --load-certificate and the private key used to
6037 sign the new proxy certificate with --load-ca-privkey. Certtool will
6038 query for proxy path length and the policy language OID. Currently
6039 only OIDs that have an empty policy are supported (which includes the
6040 two OIDs defined by RFC 3820).
6042 ** Certtool --certificate-info now prints information for Proxy Certificates.
6043 Before the proxy extension was just printed as DER encoded data.
6045 ** New APIs to set proxy subject names and get/set proxy cert extension.
6047 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
6049 ** Added self-test to test for regressions of pathLenConstraint bug.
6050 Incidentally, this also test (some) other regressions or changes in
6051 the output from certtool --certificate-info.
6053 ** When certtool generates CA certificates, pressing enter on the path
6054 ** length constraint query will now remove the field.
6055 Before it set the path length constraint to 0, which is a rather poor
6058 ** Certtool now print times in UTC when printing certificate/CRL info.
6060 ** Add better fix to work around C++ compiler bug on Mac OS X.
6061 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
6063 ** Fix import of ASCII armored OpenPGP keys.
6064 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
6066 ** Update of gnulib files.
6068 ** API and ABI modifications:
6069 gnutls_x509_crt_set_proxy_dn: ADD.
6070 gnutls_x509_crt_set_proxy: ADD.
6071 gnutls_x509_crt_get_proxy: ADD.
6073 * Version 1.7.2 (released 2007-01-14)
6075 ** Certtool now print the value of the pathLenConstraints field for certs.
6077 ** Certtool now query for path length constraints when generating CA certs.
6078 For batch uses, the certtool configuration name is "path_len".
6079 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
6081 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
6082 The new functions gnutls_x509_crt_get_basic_constraints and
6083 gnutls_x509_crt_set_basic_constraints provide a superset of the
6084 functionality in the old gnutls_x509_crt_get_ca_status and
6085 gnutls_x509_crt_set_ca_status (respectively), but the old functions
6086 will continue to be supported.
6088 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
6089 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
6090 OpenCDK release with this patch will be made soon, which should bump
6091 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
6093 ** Certtool --to-p12 can now store more than one certificate in the blob.
6094 Before it could only store one certificate, but now it will read and
6095 store as many certificate there are from the --load-certificate file.
6096 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
6098 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
6099 In particular, the OpenPGP function variables are no longer part of
6100 the exported libgnutls interface, and no header files from
6101 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
6102 were never intended for non-internal purposes, and thus this does not
6103 imply a change in the external API/ABI.
6105 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
6106 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
6108 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
6109 Before these parameters were set to make GnuTLS build under mingw32,
6110 however, they appear to no longer be necessary.
6112 ** A minor fix to the C++ library to make it build.
6113 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
6115 ** Update of gnulib files.
6117 ** API and ABI modifications:
6118 gnutls_x509_crt_get_basic_constraints: ADD.
6119 gnutls_x509_crt_set_basic_constraints: ADD.
6120 cdk_pubkey_to_sexp: ADD (in opencdk).
6121 cdk_seckey_to_sexp: ADD (in opencdk).
6123 * Version 1.7.1 (released 2006-12-28)
6125 ** TLS 1.2 server side fix.
6126 The Certificate Request sent did not contain the list of supported
6127 hashes field, thus violating the protocol. It will now contain an
6128 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
6130 ** TLS 1.2 DSA signature verification fix.
6131 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
6133 ** Fix the list of trusted CAs that server's send to clients.
6134 Before, the list contained issuer DN's instead of subject DN's of the
6135 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
6137 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
6138 Also added a self-test in tests/certificate_set_x509_crl.c to test the
6139 function. Reported by Max Kellermann <max@duempel.org>.
6141 ** Encode UID fields in DN's as DirectoryString.
6142 Before GnuTLS encoded and parsed UID fields as IA5String. This was
6143 incorrect, it should have used DirectoryString. Now it will use
6144 DirectoryString for the UID field, but for backwards compatibility it
6145 will also accept IA5String UID's. Reported by Max Kellermann
6148 ** Improve out-of-sourcedir builds from CVS.
6149 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
6151 ** Bootstrap tools changed.
6152 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
6153 building GnuTLS from CVS. Libtool 1.5.22 is used.
6155 ** Fixed a syntax error in lib/gnutls.asn.
6156 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
6158 ** Added German translation of GnuTLS messages.
6160 ** Update of gnulib files.
6162 ** API and ABI modifications:
6163 No changes since last version.
6165 * Version 1.7.0 (released 2006-11-29)
6167 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
6168 The details is that the protocol priority set by
6169 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
6170 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
6172 ** Preliminary support for TLS 1.2.
6173 The client has been successfully tested against
6174 https://www.mikestoolbox.org:4433/.
6176 ** Anonself test now print a lot of debugging info, including TLS version.
6178 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
6180 ** Update of gnulib files.
6182 ** API and ABI modifications:
6183 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
6185 *** Pulled up from stable 1.6.x branch:
6187 ** Fix ./configure failure with non-GCC compilers.
6188 This fixes the following error message:
6189 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
6190 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
6192 * Version 1.6.3 (released 2007-05-26)
6194 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
6195 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
6196 from the 1.7.x branch, see
6197 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
6199 ** Have PKCS8 parser return better error codes.
6200 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see

6204 ** Fix mem leak for sessions with client authentication via certificates.
6205 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
6206 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
6208 ** Fix building of 'tlsia' self test.
6209 Earlier some gcc are known to build tlsia linking to
6210 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
6211 the build directory, even though command line parameters look OK.
6212 Changing order of some parameters fixes it.
6214 ** API and ABI modifications:
6215 gnutls_x509_crt_get_raw_issuer_dn: ADD.
6216 gnutls_x509_crt_get_raw_dn: ADD.
6218 * Version 1.6.2 (released 2007-04-18)
6220 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
6221 Before, we remove the parameters field, which resulted in a slightly
6222 different DER encoding which in turn caused signature verification
6223 failures of GnuTLS-generated RSA certificates in some other
6224 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
6225 you read, this may or may not be correct, but our new behaviour appear
6226 to be consistent with other widely used implementations.
6228 ** Regenerate the PKIX ASN.1 syntax tree.
6229 For some reason, after changing the ASN.1 type of ldap-UID in the last
6230 release, the generated C file built from the ASN.1 schema was not
6231 refreshed. This can cause problems when reading/writing UID
6232 components inside X.500 Distinguished Names. Reported by devel
6233 <dev001@pas-world.com>.
6235 ** Updated translations.
6237 ** API and ABI modifications:
6238 No changes since last version.
6240 * Version 1.6.1 (released 2006-12-28)
6242 ** Fix the list of trusted CAs that server's send to clients.
6243 Before, the list contained issuer DN's instead of subject DN's of the
6244 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
6246 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
6247 Reported by Max Kellermann <max@duempel.org>.
6249 ** Encode UID fields in DN's as DirectoryString.
6250 Before GnuTLS encoded and parsed UID fields as IA5String. This was
6251 incorrect, it should have used DirectoryString. Now it will use
6252 DirectoryString for the UID field, but for backwards compatibility it
6253 will also accept IA5String UID's. Reported by Max Kellermann
6256 ** Fix ./configure failure with non-GCC compilers.
6257 This fixes the following error message:
6258 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
6259 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
6261 ** API and ABI modifications:
6262 No changes since last version.
6264 * Version 1.6.0 (released 2006-11-17)
6266 ** No changes since 1.5.5.
6267 The major changes compared to the 1.4.x branch are:
6269 *** A GnuTLS C++ library is part of the official distribution.
6270 Currently there are no examples or documentation, but hopefully this
6271 will change. See gnutlsxx.h for the API.
6273 *** Windows is a supported platform.
6274 There are, however, two know bugs. One is related to select() in
6275 command line tools (not, nota bene, in the library), the other is a
6276 problem with libgcrypt that causes delays. Help is needed to resolve
6277 those issues, so we feel we can't delay the release because of this.
6279 *** New APIs for custom push/pull function error reporting.
6280 The new APIs are gnutls_transport_set_errno and
6281 gnutls_transport_set_global_errno. See the release notes for version
6282 1.5.4 for more information.
6284 *** Self tests are run under valgrind, if available. See --disable-valgrind.
6286 * Version 1.5.5 (released 2006-11-16)
6288 ** Correctly bump shared library version after adding new APIs.
6289 This was forgotten in the last release.
6291 ** Fix unsigned vs signed problem in ex-x509-info.c example.
6292 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
6294 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
6296 ** Update of gnulib files.
6298 ** API and ABI modifications:
6299 No changes since last version.
6301 * Version 1.5.4 (released 2006-11-07)
6303 ** New API functions to set errno in push/pull functions.
6304 Under Windows, setting the errno variable in a push/pull replacement
6305 may end up setting the wrong errno variable, and GnuTLS send/recv
6306 functions become confused about the real errno returned from a failed
6307 push/pull function. Therefor, we have added two APIs to set the errno
6308 variable used by GnuTLS. The APIs can also help to keep things
6309 thread-safe, by avoiding potentially global variables. Typically,
6310 instead of setting errno in your push/pull function, you will call one
6311 of these functions. It is recommended to use
6312 gnutls_transport_set_errno, but if you don't have the session variable
6313 easily accessible in the push/pull replacement function, you can use
6314 gnutls_transport_set_global_errno. Suggested by Tim Kosse
6315 <tim.kosse@filezilla-project.org>.
6317 void gnutls_transport_set_errno (gnutls_session_t session, int err);
6318 void gnutls_transport_set_global_errno (int err);
6320 ** When calling `recv' or `send' Windows errors are handled properly.
6321 The Windows recv/send functions doesn't use errno, and GnuTLS now use
6322 WSAGetLastError to access the error condition instead.
6324 ** Several OpenPGP API fixes.
6325 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
6326 important fix is to change the return value of
6327 gnutls_openpgp_privkey_get_pk_algorithm and
6328 gnutls_openpgp_key_get_pk_algorithm from 'int' to
6329 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
6330 compatible with 'int').
6332 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
6333 ** version, try to negotiate the highest version support by the GnuTLS server,
6334 ** instead of the lowest.
6335 Reported by <Pasi.Eronen@nokia.com>.
6337 ** Replace old constructs with use of gnulib modules.
6338 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
6339 the code. If the headers doesn't exist on the target system, gnulib
6340 will make sure its replacement header files are used instead.
6342 ** Fix SOVERSION computation for *.def files.
6343 This fixes build errors similar to "No rule to make target
6344 `libgnutls-`expr', needed by `all-am'." when building for Windows.
6346 ** gnutls_check-version uses strverscmp from gnulib.
6348 ** Update of gnulib files.
6350 ** API and ABI modifications:
6351 gnutls_transport_set_errno: ADD
6352 gnutls_transport_set_global_errno: ADD
6354 * Version 1.5.3 (released 2006-10-26)
6356 ** Add new self-test of RSA-MD5 signature chains.
6357 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
6358 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
6359 and is based on the work by Marc Stevens et al, see
6360 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
6362 ** Re-factor self tests.
6364 ** The include copy of Libtasn1 is updated to version 0.3.7.
6366 ** The included copy of OpenCDK is updated to version 0.5.11.
6368 ** Fix the filename of the *.def file on Windows after library version bump.
6370 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
6371 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
6372 gnulib modules. Earlier we could only use the LGPL'ed module from
6373 gnulib, because two gnulib directories in the same project didn't
6376 ** API and ABI modifications:
6377 No changes since last version.
6379 * Version 1.5.2 (released 2006-10-03)
6381 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
6382 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
6383 shared library version than this version, so you'll have to remove
6384 them and possibly relink your applications. The reason for this is
6385 that no API/ABI changes have been made since the 1.4.x branch, and
6386 that incrementing the shared library version was a mistake. Reported
6387 by Andreas Metzler <ametzler@downhill.at.eu.org>.
6389 ** Fix off-by-one error when computing length to malloc.
6390 The code is used by gnutls_openpgp_add_keyring_file and
6391 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
6392 <agl@imperialviolet.org>.
6394 ** Add version script for the GnuTLS C++ library.
6395 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
6397 ** Fix the C++ compiler detection logic.
6398 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
6400 ** Update of gnulib files.
6402 ** API and ABI modifications:
6403 No changes since last version.
6405 * Version 1.5.1 (released 2006-09-21)
6407 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
6408 ** Crypto 06 rump session attack.
6409 In particular, we check that the digestAlgorithm.parameters field is
6410 missing or empty, to avoid that it can contain "garbage" that may be
6411 used to alter the numeric properties of the signature. See
6412 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
6413 not exactly the same as the problem we fix here). Reported by Yutaka
6414 OIWA <y.oiwa@aist.go.jp>.
6416 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
6417 up to date information.
6419 ** Add self test to test for above flaw.
6421 ** Fix gnutls-cli-debug regarding resume support detection.
6422 Earlier, if the session-id from the server had a length of 0, it would
6423 indicate that the server supports resumption, which isn't the case.
6424 Reported by Kataja Kai <kai.kataja@op.fi>.
6426 ** Fix building of examples on FreeBSD by including netinet/in.h.
6427 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
6429 ** Fix certtool bug that caused the private key to not be loaded when
6430 generating a certificate with --load-request, which in turn triggered
6431 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
6432 by Sascha Ziemann <sascha.ziemann@secunet.com>.
6434 ** gnutls-cli and gnutls-serv works on Windows.
6435 The problem was the select() call that doesn't work on file
6436 descriptors (stdin) on Windows. We borrowed some code from plibc to
6437 solve this. It appears to be somewhat unreliable though.
6439 ** Autoconf 2.60 is now used.
6441 ** API and ABI modifications:
6442 No changes since last version.
6444 * Version 1.5.0 (released 2006-08-13)
6446 ** Change SRP and Cert-Type extensions to match IANA registry.
6448 ** Fixed bug in OpenPGP authentication handshake.
6450 ** Improvements for building under MinGW.
6451 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
6452 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
6453 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
6454 at run-time from ws2_32.dll, and falls back on a simple replacement if
6455 it is not available. Builds the library with -mms-bitfields
6456 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
6457 create *.def files, which are installed.
6459 ** The examples now (conditionally) include config.h and link to gnulib.
6460 No other source changes were necessary, so the examples should
6461 continue to be possible to use stand-alone without any autoconf or
6464 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
6465 You may unconditionally disable it with --disable-cxx. See
6466 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
6469 ** Made command line tool '--version' behave according to GNU Standards.
6470 This enables 'make distcheck' to succeed.
6472 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
6474 ** Make --without-included-libtasn1 work.
6475 Reported by Daniel Black <dragonheart@gentoo.org>.
6477 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
6478 See http://www.gnu.org/software/gnutls/security.html regardging
6479 GNUTLS-SA-2006-2 for more up to date information. Reported by
6480 satyakumar <satyam_kkd@hyd.hellosoft.com>.
6482 ** API and ABI modifications:
6483 No changes since last version.
6485 * Version 1.4.5 (released 2006-11-06)
6487 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
6488 ** version, try to negotiate the highest version support by the GnuTLS server,
6489 ** instead of the lowest.
6490 Reported by <Pasi.Eronen@nokia.com>.

6493 Reported by Adam Langley" <agl@imperialviolet.org>.
6495 ** API and ABI modifications:
6496 No changes since last version.
6498 * Version 1.4.4 (released 2006-09-12)
6500 ** Relax the test that caught signatures that exploit the variant of
6501 ** Bleichenbacher's Crypto 06 rump session attack on our
6502 ** verification logic flaw.
6503 In particular, we now permit the digestAlgorithm.parameters field to
6504 be present but empty, whereas in 1.4.3 we actually checked that the
6507 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
6508 The messages are only printed in debug mode, which is not recommended
6509 for normal use, and thus logging this situation cannot be abused as an
6510 oracle in typical recommended situations.
6512 ** API and ABI modifications:
6513 No changes since last version.
6515 * Version 1.4.3 (released 2006-09-08)
6517 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
6518 ** Crypto 06 rump session attack.
6519 In particular, we check that the digestAlgorithm.parameters field is
6520 empty, to avoid that it can contain "garbage" that may be used to
6521 alter the numeric properties of the signature. See
6522 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is

6529 ** Fix PKCS#1 decryption to avoid Bleichenbacher's Crypto 98 attack.
6530 See <http://www.bell-labs.com/user/bleichen/papers/pkcs.ps.gz>.

6536 ** Fix crash in gnutls_x509_crt_sign2 if passed a NULL issuer_key.
6538 ** API and ABI modifications:
6539 No changes since last version.
6541 * Version 1.4.2 (released 2006-08-12)
6543 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
6544 This can happen if you call gnutls_certificate_verify_peers2 and have
6545 a certain mix of local CA certificates and the peer send special
6546 certificates, that together trigger certain behaviour. It is not
6547 known at this point whether the crash can be triggered without the
6548 special local CA certificate, and thus turn this into a remote crash
6549 of clients that verify server certificates when they talk to a server
6550 with the special server certificate. See GNUTLS-SA-2006-2 on
6551 http://www.gnu.org/software/gnutls/security.html for more up to date
6552 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
6554 ** Change SRP and Cert-Type extensions to match IANA registry.
6556 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
6558 ** Make --without-included-libtasn1 work.
6559 Reported by Daniel Black <dragonheart@gentoo.org>.
6561 ** API and ABI modifications:
6562 No changes since last version.
6564 * Version 1.4.1 (released 2006-06-14)
6566 ** Replaced inactive ifdefs to enable openpgp support in test programs.
6568 ** Fixed bug in OpenPGP authentication handshake.
6570 ** Fixed typographical in man pages.
6572 ** Build fixes of the manual.
6574 ** Added Swedish translation.
6576 ** API and ABI modifications:
6577 No changes since last version.
6579 * Version 1.4.0 (released 2006-05-15)
6581 ** Remove GnuTLS 0.8.x compatibility functions.
6583 ** The libgcrypt RNG is initialized in gnutls_global_init().
6585 ** TLS/IA API changes from Emile van Bergen.
6586 A dummy credential structure is not needed now, if you wish to use the
6587 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
6590 ** The self-tests are now run under valgrind, if it is installed.
6592 ** Libtasn1 is updated to 0.3.4, and that version is now required.
6594 ** The command line tools now use getaddrinfo and support IPv6.
6596 ** API and ABI modifications:
6597 _gnutls_x509_get_raw_crt_activation_time,
6598 _gnutls_x509_get_raw_crt_expiration_time: Removed.
6599 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
6600 gnutls_ia_enable: Added.
6602 * Version 1.3.5 (released 2006-03-08)
6604 ** Error messages are now translated using GNU Gettext.
6606 ** The function gnutls_x509_crt_to_xml now return an internal error.
6607 This means that the code to convert X.509 certificates to XML format
6608 does not work any more. The reason is that the function called
6609 libtasn1 internal functions. It seems unclean for libtasn1 to export
6610 the APIs needed here. Instead it would be better to implement XML
6611 support inside libtasn1 properly. If you need this functionality
6612 strongly, please consider looking into implementing this suggested
6613 approach instead. As a workaround, you may also modify lib/x509/xml.c
6614 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
6616 ** Libraries are now built with libtool's -no-undefined.
6617 This helps producing libraries for Windows using mingw32.
6619 ** Doc fixes to explain that gnutls_record_send can block.
6621 ** Libtasn1 0.3.1 or later is now required.
6622 The include copy has been updated too.
6624 ** gnutls-cli can now recognize services and port numbers with the -p option.
6626 ** API and ABI modifications:
6627 No changes since last version.
6629 * Version 1.3.4 (released 2006-02-09)
6631 ** Fix read of out bounds bug in DER parser.
6632 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
6633 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
6634 previous bug fix. The included libtasn1 version in GnuTLS has been
6637 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
6638 longer invalidate a session if the underlying send fails, but it will
6639 prevent future writes. That is to allow reading the already received data.
6640 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
6642 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
6643 gnutls_certificate_set_x509_trust(), that caused memory corruption if
6644 more than one certificates were added. Report and patch by Max Kellermann.
6646 ** Fix build problems of OpenCDK on AIX.
6647 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
6649 ** API and ABI modifications:
6650 No changes since last version.
6652 * Version 1.3.3 (released 2006-01-12)
6654 ** New API to access the TLS master secret.
6655 When possible, you should use the TLS PRF functions instead.
6656 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
6658 ** Improved handling when multiple libraries use GnuTLS at the same time.
6659 Now gnutls_global_init() can be called multiple times, and
6660 gnutls_global_deinit() will only deallocate the structure when it has
6661 been called as many times as gnutls_global_init() was called.
6663 ** Added a self test of TLS resume functionality.
6665 ** Fix crash in TLS resume code, caused by TLS/IA changes.
6667 ** Documentation fixes about thread unsafety, prompted by
6668 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
6669 In particular, gnutls_global_init() and gnutls_global_deinit() are not
6670 thread safe. Careful callers may want to protect the call using a
6671 mutex. The problem could also be ignored, which would cause a memory
6672 leak under rare conditions when two threads invoke the function
6673 roughly at the same time.
6675 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
6677 ** The code was indented again, including the external header files.
6679 ** API and ABI modifications:
6680 New functions to retrieve the master secret value:
6681 gnutls_session_get_master_secret
6683 Add a 'const' keyword to existing API:
6684 gnutls_x509_crq_get_challenge_password
6686 * Version 1.3.2 (released 2005-12-15)
6688 ** GnuTLS now support TLS Inner application (TLS/IA).
6689 This is per draft-funk-tls-inner-application-extension-01. This
6690 functionality is added to libgnutls-extra, so it is licensed under the
6691 GNU General Public License.
6693 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
6694 The PRF is used by some protocols building on TLS, such as EAP-PEAP
6695 and EAP-TTLS. One function to access the raw PRF and one to access
6696 the PRF seeded with the client/server random fields are provided.
6697 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
6699 ** New APIs to acceess the client and server random fields in a session.
6700 These fields can be useful by protocols using TLS. Note that these
6701 fields are typically used as input to the TLS PRF, and if this is your
6702 intended use, you should use the TLS PRF API that use the
6703 client/server random field directly. Suggested by Jouni Malinen
6704 <jkmaline@cc.hut.fi>.
6706 ** Internal type cleanups.
6707 The uint8, uint16, uint32 types have been replaced by uint8_t,
6708 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
6709 correct types on platforms that lack them. The uint type have been
6710 replaced by unsigned.
6712 ** API and ABI modifications:
6713 New functions to invoke the TLS Pseudo-Random-Function (PRF):
6717 New functions to retrieve the session's client and server random values:
6718 gnutls_session_get_server_random
6719 gnutls_session_get_client_random
6721 New function, to perform TLS/IA handshake:
6724 New function to decide whether to do a TLS/IA handshake:
6725 gnutls_ia_handshake_p
6727 New functions to allocate a TLS/IA credential:

6770 New error code to signal TLS/IA verify failure:
6771 GNUTLS_E_IA_VERIFY_FAILED
6773 * Version 1.3.1 (released 2005-12-08)
6775 ** Support for DHE-PSK cipher suites has been added.
6776 This method offers perfect forward secrecy.
6778 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
6779 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
6781 ** Corrected a bug in certtool for 64 bit machines. Reported
6782 by Max Kellermann <max@duempel.org>.
6784 ** New function to set a X.509 private key and certificate pairs, and/or
6785 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
6786 <emile@e-advies.nl>.
6788 The integrity of the PKCS#12 file is protected through a password
6789 based MAC; public-key based signatures for integrity protection are
6790 not supported. PKCS#12 bags may be encrypted using password derived
6791 symmetric keys, public-key based encryption is not supported. The
6792 PKCS#8 keys may be encrypted using passwords. The API use the same
6793 password for all operations. We believe that any more flexibility
6794 create too much complexity that would hurt overall security, but may
6795 add more PKCS#12 related APIs if real-world experience indicate
6798 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
6799 reported by Emile van Bergen <emile@e-advies.nl>.
6800 This will enable "certtool -k -8" to parse those keys.
6802 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
6803 Use "certtool -p -8" and press press enter at the prompt. Earlier,
6804 certtool would have encrypted the key using an empty password.
6806 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
6807 Earlier it would have prompted the user for it, even if --password was
6810 ** Added self test of PKCS#8 parsing.
6811 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
6812 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
6815 ** API and ABI modifications:
6816 New function to set X.509 credentials from a PKCS#12 file:
6817 gnutls_certificate_set_x509_simple_pkcs12_file
6819 New gnutls_kx_algorithm_t enum type:
6822 New API to return session data (basically same as gnutls_session_get_data):
6823 gnutls_session_get_data2
6825 New API to set PSK Diffie-Hellman parameters:
6826 gnutls_psk_set_server_dh_params
6828 * Version 1.3.0 (2005-11-15)
6830 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
6831 This add several new APIs, see below. Read the updated manual for
6832 more information. A new self test "pskself" has been added, that will
6833 test this functionality.
6835 ** The session resumption data are now system independent.
6837 ** The code has been re-indented to conform to the GNU coding style.
6839 ** Removed the RIPEMD ciphersuites.
6841 ** Added a discussion of the internals of gnutls in manual.
6843 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
6845 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
6847 ** Make sure config.h is included first in a few files, from Albert Chin.
6849 ** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
6851 ** Don't install SRP programs and man pages if --disable-srp-authentication,
6854 ** API and ABI modifications:
6855 New gnutls_kx_algorithm_t key exchange type: GNUTLS_KX_PSK
6857 New gnutls_credentials_type_t credential type:
6860 New credential types:
6861 gnutls_psk_server_credentials_t
6862 gnutls_psk_client_credentials_t
6864 New functions to allocate PSK credentials:
6865 gnutls_psk_allocate_client_credentials

6871 gnutls_psk_key_flags
6873 New function prototypes for credential callback:
6874 gnutls_psk_client_credentials_function
6875 gnutls_psk_server_credentials_function
6877 New function to set PSK username and key:
6878 gnutls_psk_set_client_credentials
6880 New function to set PSK passwd file:
6881 gnutls_psk_set_server_credentials_file
6883 New function to extract PSK user in server:
6884 gnutls_psk_server_get_username
6886 New functions to set PSK callback:
6887 gnutls_psk_set_server_credentials_function
6888 gnutls_psk_set_client_credentials_function
6890 Use size_t instead of int for output size parameter:
6891 gnutls_srp_base64_encode
6892 gnutls_srp_base64_decode
6894 * Version 1.2.11 (2006-05-11)
6895 - The function gnutls_x509_crt_to_xml is not supported any more, and
6896 return an internal error. The reason is that the function called
6897 internal libtasn1 functions which are no longer exported from
6899 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
6900 - Updated gnulib compatibility files.
6901 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
6902 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
6903 - API and ABI modifications:
6904 No changes since last version.
6906 * Version 1.2.10 (2006-02-09)
6907 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
6908 <admin@gleg.net>, and debugging help from Protover SSL.
6909 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
6910 The included version has been updated too.
6911 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
6912 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
6913 - Corrected a bug in certtool for 64 bit machines. Reported
6914 by Max Kellermann <max@duempel.org>.
6915 - Corrected bugs in gnutls_certificate_set_x509_crl() and
6916 gnutls_certificate_set_x509_trust(), that caused memory corruption if
6917 more than one certificates were added. Report and patch by Max Kellermann.
6918 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
6919 longer invalidate a session if the underlying send fails, but it will
6920 prevent future writes. That is to allow reading the already received data.
6921 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
6923 * Version 1.2.9 (2005-11-07)
6924 - Documentation was updated and improved.
6925 - RSA-MD2 is now supported for verifying digital signatures.
6926 - Due to cryptographic advances, verifying untrusted X.509
6927 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
6928 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
6929 applications that must remain interoperable, you can use the
6930 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
6931 flags when verifying certificates. Naturally, this is not
6932 recommended default behaviour for applications. To enable the
6933 broken algorithms, call gnutls_certificate_set_verify_flags with the
6934 proper flag, to change the verification mode used by
6935 gnutls_certificate_verify_peers2.
6936 - Make it possible to send empty data through gnutls_record_send,
6937 to align with the send(2) API.
6938 - Some changes in the certificate receiving part of handshake to prevent
6939 some possible errors with non-blocking servers.
6940 - Added numeric version symbols to permit simple CPP-based feature
6941 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
6942 - The (experimental) low-level crypto alternative to libgcrypt used
6943 earlier (Nettle) has been replaced with crypto code from gnulib.
6944 This leads to easier re-use of these components in other projects,
6945 leading to more review and simpler maintenance. The new configure
6946 parameter --with-builtin-crypto replace the old --with-nettle, and
6947 must be used if you wish to enable this functionality. See README
6948 under "Experimental" for more information. Internally, GnuTLS has
6949 been updated to use the new "Generic Crypto" API in gl/gc.h. The
6950 API is similar to the old crypto/gc.h, because the gnulib code were
6951 based on GnuTLS's gc.h.
6952 - Fix compiler warning in the "anonself" self test.
6953 - API and ABI modifications:
6954 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
6955 This doesn't reflect a change in behaviour,
6956 so we don't break backwards compatibility.
6957 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
6958 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
6959 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
6960 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
6962 gnutls_x509_crt_list_verify,
6963 gnutls_x509_crt_verify, or
6964 gnutls_certificate_set_verify_flags.
6965 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
6966 used when broken signature algorithms
6967 is used (currently RSA-MD2/MD5).
6968 LIBGNUTLS_VERSION_MAJOR,
6969 LIBGNUTLS_VERSION_MINOR,
6970 LIBGNUTLS_VERSION_PATCH,
6971 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
6972 version number, can be used for feature existence
6975 * Version 1.2.8 (2005-10-07)
6976 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
6977 - Don't install the auxilliary libexamples library used by the
6978 examples in doc/examples/ on "make install", report and tiny patch
6979 from Thomas Klausner <tk@giga.or.at>.
6980 - If you pass a X.509 CA or PGP trust database to the command line
6981 tool, it will now abort the connection if the server certificate
6982 validation fails. Use the parameter --insecure to continue even
6983 after certificate validation failures. Inspired from discussion
6984 with Alexander Kotelnikov <sacha@myxomop.com>.
6985 - The test for socklen_t has been moved to gnulib.
6986 - Link failures for duplicate or missing "program_name" symbol has been fixed,

7043 - Corrected some bugs that could affect 64 bit systems.
7044 - Some corrections in the header files to include the prototype
7045 of memmem properly (affected 64 bit systems). Report and patch
7046 by Yoann Vandoorselaere <yoann@prelude-ids.org>.
7047 - Introduced the --fix-key option to certtool, which can be used to
7048 regenerate the (optional) parameters in a private key. It should
7049 be used together with --key-info.
7050 - Corrected a bug in certificate chain verification that could lead
7051 to marking a trusted chain as non trusted, if the last certificate in
7052 the chain was a self signed one.
7053 - Gnulib portability files were updated.
7054 - License were updated to reflect new FSF address.

7083 are not in the included list.
7084 - Added warning to certtool when MD5 is being used for digital
7086 - Optimizations ("-O2 -finline-functions") are not enabled by default,
7087 instead the standard autoconf defaults are used. Use `./configure
7088 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
7089 - Added the option --get-dh-params to certtool, in order to get the
7090 parameters included in the library primes and generators.

7094 - Nettle self tests now build properly, reported by Pierre
7095 <pierre42d@9online.fr>.
7096 - Eliminated some memory leaks in DHE and RSA-EXPORT cipher suites.
7097 Reported by Yoann Vandoorselaere <yoann@prelude-ids.org>.
7098 - If the library has been compiled with features disabled, a warning is
7099 issued during the compilation of any program.
7100 - API and ABI modifications:

7126 gnutls_x509_rdn_get now set *sizeof_buf to the buffer length that is
7127 required, instead of the string length. That is, the value has been
7128 incremented by 1 to account for the terminating zero. Reported by
7129 Martin Lambers <marlam@web.de>.
7130 - Debug output shouldn't crash on platforms that doesn't handle NULL
7131 printf %s values. Reported by Michael.Ringe@aachen.utimaco.de.
7132 - Sync included copy of libtasn1 with version 0.2.13.

7173 a key and no certificate to PKCS#12.
7174 - Fix objdir != srcdir builds, reported by "Gerrit P. Haase"
7175 <gp@familiehaase.de>.
7176 - Fixes faulty getpass implementation in libextra/opencdk/, reported
7177 by Yoann Vandoorselaere <yoann@prelude-ids.org>.
7178 - Uses memmem instead of strnstr in lib/.
7179 - Using more GNULib portability files, although not yet inside lib/.
