541 * Version 2.11.1 (released 2010-09-14)
543 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
544 to use the libgcrypt back end.
546 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
547 backend crypto library.
549 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
551 ** libgnutls: Several updates in the buffering internal interface.

556 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
558 ** libgnutls: The %COMPAT flag now allows larger records that violate the
561 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
562 system calls. Applications that depended on it being 1 should explicitly call
563 gnutls_transport_set_lowat().
565 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
566 to ECRYPT II recommendations. Mappings were moved to a single location
567 and DSA keys are handled differently (since DSA2 allows for 1024,2048
570 ** libgnutls: gnutls_x509_privkey_import() will fallback to
571 gnutls_x509_privkey_import_pkcs8() without a password, if it
572 is unable to decode the key.
574 ** libgnutls: HMAC-MD5 no longer used by default.
576 ** API and ABI modifications:
577 gnutls_openpgp_privkey_sec_param: ADDED

580 * Version 2.11.0 (released 2010-07-22)
582 ** libgnutls: support scattered write using writev(). This takes
583 advantage of the new buffering layer and allows queuing of packets
584 and flushing them. This is currently used for handshake messages
587 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
588 alternative locking procedures. By default the system available
589 locking is used. In *NIX pthreads are used and in windows the
590 critical section API. This follows a different approach than the
591 previous versions that depended on libgcrypt initialization. The
592 locks are now set by default in systems that support it. Programs
593 that used gcry_control() to set thread locks should insert it into
595 #if GNUTLS_VERSION_NUMBER <= 0x020b00
599 ** libgnutls: Added support for reading DN from EV-certificates.
601 jurisdictionOfIncorporationLocalityName,
602 jurisdictionOfIncorporationStateOrProvinceName,
603 jurisdictionOfIncorporationCountryName
605 ** libgnutls: Added support for DSA signing/verifying with bit
608 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
609 has to be called to register any required md5 handlers.
611 ** libgnutls: Internal buffering code was replaced by simpler
612 code contributed by Jonathan Bastien-Filiatrault.
614 ** libgnutls: Internal API for extensions augmented to allow
615 safe storing and loading of data on resumption. This allows writing
616 self-contained extensions (when possible). As a side effect
617 the OPRFI extension was removed.
619 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
621 ** libgnutls: Added PKCS #11 support and an API to access objects in
622 gnutls/pkcs11.h. Currently certificates and public keys can be
623 imported from tokens, and operations can be performed on private keys.
625 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
627 ** libgnutls: Added initial support for the nettle library. It uses
628 the system's random generator for seeding. That is /dev/urandom in Linux,
629 system calls in Win32 and EGD on other systems.
631 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
632 works even when resuming a session.
634 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
635 similar gnutls_certificate_set_server_retrieve_function() and
636 gnutls_certificate_set_client_retrieve_function(). In addition it support
637 PKCS #11 private keys.
639 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
640 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
642 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
643 sizes for private keys using a human understandable scale.
645 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
646 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
647 --pkcs11-delete-url, --pkcs11-write
649 certtool: The --pkcs-cipher is taken into account when generating a
650 private key. The default cipher used now is aes-128. The old behavior can
651 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
653 certtool: Added --certificate-pubkey to print the public key of the
656 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
657 can now accept a PKCS #11 URL in addition to a file. This will allow for
658 example to use the Gnome-keyring trusted certificate list to verify
659 connections using a url such as:
660 pkcs11:token=Root%20CA%20Certificates;serial=1%3AROOTS%3ADEFAULT;model=1%2E0;manufacturer=Gnome%20Keyring

741 * Version 2.10.1 (released 2010-07-25)
743 ** libgnutls: Added support for broken certificates that indicate RSA
746 ** gnutls-cli: Allow verification using V1 CAs.
748 ** libgnutls: gnutls_x509_privkey_import() will fallback to
749 gnutls_x509_privkey_import_pkcs8() without a password, if it
750 is unable to decode the key.
752 ** libgnutls: Correctly deinitialize crypto API functions to prevent
753 a memory leak. Reported by Mads Kiilerich.
755 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
756 issue a warning, that the output key might not be working everywhere.
758 ** certtool: The --pkcs-cipher is taken into account when generating a
759 private key. The default cipher used now is aes-128. The old behavior
760 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
762 ** API and ABI modifications:
763 No changes since last version.
765 * Version 2.10.0 (released 2010-06-25)
767 ** API and ABI modifications:
768 No changes since last version.
770 * Version 2.9.12 (released 2010-06-17)
772 ** gnutls-cli: Make --starttls work again.
773 Problem introduced in patch to use read() instead of fgets() committed
776 ** API and ABI modifications:
777 No changes since last version.
779 * Version 2.9.11 (released 2010-06-07)
781 ** libgnutls: Removed two APIs related to safe renegotiation.
782 Use priority strings instead. The APIs were
783 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
784 (Remember that we don't promise ABI stability during development
785 series, so this doesn't cause an shared library ABI increment.)
787 ** tests: More self testing of safe renegotiation extension.
788 See tests/safe-renegotiation/README for more information.
790 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
792 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
794 ** API and ABI modifications:
795 gnutls_safe_negotiation_set_initial: REMOVED.
796 gnutls_safe_renegotiation_set: REMOVED.
798 * Version 2.9.10 (released 2010-04-22)
800 ** libgnutls: Time verification extended to trusted certificate list.
801 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
804 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
805 Based on patch by Pavan Konjarla. Adds new constant
806 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
808 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
809 Solves the issue discussed in:
810 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
811 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
812 Note that to allow connecting to unpatched servers the full protection
813 is only enabled if the priority string %SAFE_RENEGOTIATION is
814 specified. You can check whether protection is in place by querying
815 gnutls_safe_renegotiation_status(). New error codes
816 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
817 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
819 ** libgnutls: When checking openpgp self signature also check the signatures
821 Ilari Liusvaara noticed and reported the issue and provided test
824 ** libgnutls: Added cryptodev support (/dev/crypto).
825 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
826 benchmark utility for AES. Adds new error codes
827 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
829 ** libgnutls: Exported API to access encryption and hash algorithms.
830 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
831 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
832 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
833 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
834 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
835 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
836 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
838 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
839 verification of certificate upon receipt rather than waiting until the
840 end of the handshake.
842 ** libgnutls: Don't send alerts during handshake.
843 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
845 ** certtool: Corrected two issues that affected certificate request generation.
846 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
847 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
848 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
849 those parameters there since other implementations don't do either and having
850 them does not seem to offer anything (anyway you need the signer's certificate
851 to verify thus public key will be available). Found thanks to Boyan Kasarov.
852 This however has the side-effect that public key IDs shown by certtool are
853 now different than previous gnutls releases.
854 (3) the option --pgp-certificate-info will verify self signatures
856 ** certtool: Allow exporting of Certificate requests on DER format.
858 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
860 ** gnutls-cli: Handle reading binary data from server.

928 Reported by Tang Tong.
930 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
931 ** extension and certificate verify field.
932 This requires changes for TLS 1.2 servers and clients that use
933 callbacks for certificate retrieval. They are now required to check
934 with gnutls_sign_algorithm_get_requested() whether the certificate
935 they send complies with the peer's preferences in signature
938 ** libgnutls: In server side when resuming a session do not overwrite the
939 ** initial session data with the resumed session data.
941 ** libgnutls: Added support for AES-128, AES-192 and AES-256 in PKCS #8
943 This affects also PKCS #12 encoded files. This adds the following new
944 enums: GNUTLS_CIPHER_AES_192_CBC, GNUTLS_PKCS_USE_PBES2_AES_128,
945 GNUTLS_PKCS_USE_PBES2_AES_192, GNUTLS_PKCS_USE_PBES2_AES_256.
947 ** libgnutls: Fix PKCS#12 encoding.
948 The error you would get was "The OID is not supported.". Problem
949 introduced for the v2.8.x branch in 2.7.6.
951 ** certtool: Added the --pkcs-cipher option.
952 To explicitely specify the encryption algorithm to use.

1010 ** libgnutls: Client-side TLS 1.2 and SHA-256 ciphersuites now works.
1011 The new supported ciphersuites are AES-128/256 in CBC mode with
1012 ANON-DH/RSA/DHE-DSS/DHE-RSA. Contributed by Daiki Ueno. Further,
1013 SHA-256 is now the preferred default MAC (however it is only used with
1016 ** libgnutls: Make OpenPGP hostname checking work again.
1017 The patch to resolve the X.509 CN/SAN issue accidentally broken
1018 OpenPGP hostname comparison.
1020 ** libgnutls: When printing X.509 certificates, handle XMPP SANs better.
1021 Reported by Howard Chu <hyc@symas.com> in
1022 <https://savannah.gnu.org/support/?106975>.
1024 ** Fix use of deprecated types internally.
1025 Use of deprecated types in GnuTLS from now on will lead to a compile
1026 error, to prevent this from happening again.
1028 ** API and ABI modifications:
1029 No changes since last version.
1031 * Version 2.9.3 (released 2009-08-19)
1033 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
1034 The new APIs are gnutls_session_ticket_enable_client,
1035 gnutls_session_ticket_enable_server, and
1036 gnutls_session_ticket_key_generate.
1038 ** gnutls-cli, gnutls-serv: New parameter --noticket to disable TLS tickets.

1043 gnutls_session_ticket_enable_server: ADDED.
1045 * Version 2.9.2 (released 2009-08-14)
1047 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
1048 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
1049 into 1) not printing the entire CN/SAN field value when printing a
1050 certificate and 2) cause incorrect positive matches when matching a
1051 hostname against a certificate. Some CAs apparently have poor
1052 checking of CN/SAN values and issue these (arguable invalid)
1053 certificates. Combined, this can be used by attackers to become a
1054 MITM on server-authenticated TLS sessions. The problem is mitigated
1055 since attackers needs to get one certificate per site they want to
1056 attack, and the attacker reveals his tracks by applying for a
1057 certificate at the CA. It does not apply to client authenticated TLS
1058 sessions. Research presented independently by Dan Kaminsky and Moxie
1059 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
1060 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
1062 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
1063 The function may fail incorrectly when an earlier certificate was
1064 imported to the same gnutls_x509_crt_t structure.
1066 ** minitasn1: Internal copy updated to libtasn1 v2.3.
1068 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
1069 Before it always returned false. Reported by Peter Hendrickson
1070 <pdh@wiredyne.com> in
1071 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3668>.
1073 ** libgnutls: Fix off-by-one size computation error in unknown DN printing.

1140 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
1141 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
1143 Note: As a side effect of this change, the "public key identifier"
1144 value computed for a certificate using this version of GnuTLS will be
1145 different from values computed using earlier versions of GnuTLS.
1147 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
1148 ** optional SignatureAlgorithm parameter field.
1149 VeriSign rejected these CSRs. They are stricly speaking not needed

1235 * Version 2.8.2 (released 2009-08-10)
1237 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
1238 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
1239 into 1) not printing the entire CN/SAN field value when printing a
1240 certificate and 2) cause incorrect positive matches when matching a
1241 hostname against a certificate. Some CAs apparently have poor
1242 checking of CN/SAN values and issue these (arguable invalid)
1243 certificates. Combined, this can be used by attackers to become a
1244 MITM on server-authenticated TLS sessions. The problem is mitigated
1245 since attackers needs to get one certificate per site they want to
1246 attack, and the attacker reveals his tracks by applying for a
1247 certificate at the CA. It does not apply to client authenticated TLS
1248 sessions. Research presented independently by Dan Kaminsky and Moxie
1249 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
1250 for providing one part of the patch. [GNUTLS-SA-2009-4].

1411 No offically supported interfaces have been modified or removed. The
1412 library should be completely backwards compatible on both the source
1415 The shared library no longer exports some symbols that have never been
1416 officially supported, i.e., not mentioned in any of the header files.
1422 Normally when symbols are removed, the shared library version has to
1423 be incremented. This leads to a significant cost for everyone using
1424 the library. Because none of the above symbols have ever been
1425 intended for use by well-behaved applications, we decided that the it
1426 would be better for those applications to pay the price rather than
1427 incurring problems on the majority of applications.
1429 If it turns out that applications have been using unofficial
1430 interfaces, we will need to release a follow-on release on the v2.8
1431 branch to exports additional interfaces. However, initial testing
1432 suggests that few if any applications have been using any of the
1435 Although not a new change compared to 2.6.x, we'd like to remind you
1436 interfaces have been modified so that X.509 chain verification now
1437 also checks activation/expiration times on certificates. The affected
1440 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.

1447 This change in behaviour was made during the GnuTLS 2.6.x cycle, and
1448 we gave our rationale for it in earlier release notes.

1608 ** libgnutls: Fix DSA key generation.
1609 Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
1611 ** libgnutls: Check expiration/activation time on untrusted certificates.
1612 Merged from stable branch. Reported by Romain Francoise
1613 <romain@orebokech.com>. This changes the semantics of
1614 gnutls_x509_crt_list_verify, which in turn is used by
1615 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
1616 We add two new gnutls_certificate_status_t codes for reporting the new
1617 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
1618 We also add a new gnutls_certificate_verify_flags flag,
1619 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
1620 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
1622 ** lib: Linker version scripts reduces number of exported symbols.
1623 The linker version script now lists all exported ABIs explicitly, to
1624 avoid accidentally exporting unintended functions. Compared to
1625 before, most symbols beginning with _gnutls* are no longer exported.
1626 These functions have never been intended for use by applications, and
1627 there were no prototypes for these function in the public header
1628 files. Thus we believe it is possible to do this without incrementing
1629 the library ABI version which normally has to be done when removing an
1632 ** lib: Limit exported symbols on systems without LD linker scripts.
1633 Before all symbols were exported. Now we limit the exported symbols
1634 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
1635 _gnutls*. This is a superset of the actual supported ABI, but still
1636 an improvement compared to before. This is implemented using Libtool
1637 -export-symbols-regex. It is more portable than linker version
1640 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
1641 This should have been done in the last release.
1643 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.

1647 ** doc: Improved sections for the info manual.
1648 We now follow the advice given by the texinfo manual on which
1649 directory categories to use. In particular, libgnutls moved from the

1662 * Version 2.7.7 (released 2009-04-20)
1664 ** libgnutls: Applied patch by Cedric Bail to add functions
1665 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().

1679 It is currently only used by the core library. This will enable a new
1680 domain 'gnutls' for translations of the command line tools.
1682 ** Corrected possible memory corruption on signature verification failure.

1691 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
1692 This applies both to generating certificates and certificate requests.
1694 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
1696 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
1697 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
1698 be used for chain verification.
1700 ** gnutls-serv: No longer disable MAC padding by default.
1701 Use --priority NORMAL:%COMPAT to disable MAC padding again.
1703 ** gnutls-cli: Certificate information output format changed.
1704 The tool now uses libgnutls' functions to print certificate
1705 information. This avoids code duplication.
1707 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
1708 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
1709 They can be used to override the default certificate chain validation
1712 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
1713 specify the client hello message record version. Used to overcome buggy
1714 TLS servers. Report by Martin von Gagern.

1723 No changes since last version.
1725 * Version 2.7.5 (released 2009-02-06)
1727 ** libgnutls: Accept chains where intermediary certs are trusted.
1728 Before GnuTLS needed to validate the entire chain back to a
1729 self-signed certificate. GnuTLS will now stop looking when it has
1730 found an intermediary trusted certificate. The new behaviour is
1731 useful when chains, for example, contains a top-level CA, an
1732 intermediary CA signed using RSA-MD5, and an end-entity certificate.
1733 To avoid chain validation errors due to the RSA-MD5 cert, you can
1734 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
1735 The signature on trusted certificates are not checked, so the chain
1736 has a chance to validate correctly. Reported by "Douglas E. Engert"

1738 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
1740 ** libgnutls: result_size in gnutls_hex_encode now holds
1741 the size of the result. Report by John Brooks <special@dereferenced.net>.
1743 ** libgnutls: gnutls_handshake when sending client hello during a
1744 rehandshake, will not offer a version number larger than the current.
1745 Reported by Tristan Hill <stan@saticed.me.uk>.
1747 ** libgnutls: Permit V1 Certificate Authorities properly.
1748 Before they were mistakenly rejected even though
1749 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
1750 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
1751 "Douglas E. Engert" <deengert@anl.gov> in

1755 No changes since last version.
1757 * Version 2.7.4 (released 2009-01-07)
1759 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
1760 This is a bugfix -- the previous attempt to do this from internal x509
1761 certificate verification procedures did not return the correct value
1762 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
1763 <dkg@fifthhorseman.net> in
1764 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,

1769 Patch from David Marín Carreño <davefx@gmail.com> in
1770 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
1772 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
1774 ** certtool: --verify-chain now prints results of using library verification.
1775 Earlier, certtool --verify-chain used its own validation algorithm
1776 which wasn't guaranteed to give the same result as the libgnutls
1777 internal validation algorithm. Now this command print a new final
1778 line with header 'Chain verification output:' that contains the result
1779 from using the internal verification algorithm on the same chain.
1781 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
1783 ** API and ABI modifications:
1784 gnutls_x509_crq_get_key_id: ADDED.
1786 * Version 2.7.3 (released 2008-12-10)

1794 ** libgnutls: Libgcrypt initialization changed.
1795 If libgcrypt has not already been initialized, GnuTLS will now
1796 initialize libgcrypt with disabled secure memory. Initialize
1797 libgcrypt explicitly in your application if you want to enable secure
1798 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
1799 allocation functions, which doesn't use secure memory, so there is no
1800 real change in behaviour.
1802 ** libgnutls: Fix memory leak in PSK authentication.
1803 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
1804 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
1806 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
1808 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
1809 It needs to be invoked before libgcrypt is initialized.
1811 ** gnutls-cli: Return non-zero exit code on error conditions.
1813 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
1815 ** tests: Added chainverify self-test that tests X.509 chain verifications.

1822 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
1823 The flaw makes it possible for man in the middle attackers (i.e.,
1824 active attackers) to assume any name and trick GnuTLS clients into
1825 trusting that name. Thanks for report and analysis from Martin von
1826 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
1828 Any updates with more details about this vulnerability will be added
1829 to <http://www.gnu.org/software/gnutls/security.html>
1831 ** libgnutls: Fix namespace issue with version symbols.
1832 The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
1833 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
1834 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
1835 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
1836 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
1837 work but are deprecated.

1957 ** libgnutls: Corrected double free on signature verification failure.
1958 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
1959 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
1961 ** libgnutls: Fix DSA key generation.
1962 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
1963 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
1964 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
1966 ** libgnutls: Check expiration/activation time on untrusted certificates.
1967 Reported by Romain Francoise <romain@orebokech.com>. Before the
1968 library did not check activation/expiration times on certificates, and
1969 was documented as not doing so. We have realized that many
1970 applications that use libgnutls, including gnutls-cli, fail to perform
1971 proper checks. Implementing similar logic in all applications leads
1972 to code duplication. Hence, we decided to check whether the current
1973 time (as reported by the time function) is within the
1974 activation/expiration period of certificates when verifying untrusted
1977 This changes the semantics of gnutls_x509_crt_list_verify, which in
1978 turn is used by gnutls_certificate_verify_peers and
1979 gnutls_certificate_verify_peers2. We add two new
1980 gnutls_certificate_status_t codes for reporting the new error
1981 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
1982 add a new gnutls_certificate_verify_flags flag,
1983 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new

2134 ** certtool: Use inet_pton for parsing IPv6 addresses.
2136 ** Major changes compared to the v2.4 branch:
2138 *** Added API to replace and update the crypto backend.
2140 *** certtool: can add several subject alternative names via template file.
2142 *** opencdk: Parse (but not decrypt) encrypted secret keys.
2144 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
2145 either set or append alternative names. It can also handle binary structures
2146 such as IP addresses.
2148 *** libgnutls: New function to set minimum acceptable SRP bits.
2149 The function is gnutls_srp_set_prime_bits.
2151 *** libgnutls: Add interface to deal with public key and signature algorithms.
2152 The functions are called gnutls_pk_list, gnutls_pk_get_id,
2153 gnutls_sign_list, and gnutls_sign_get_id.
2155 *** libgnutls: New interfaces to get name of public key and signing algorithms.
2156 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
2158 *** libgnutls: New API to get a string corresponding to a error symbol.
2159 The function is gnutls_strerror_name.

2162 *** from a private key.
2163 The function is gnutls_x509_crq_set_key_rsa_raw.
2165 *** libgnutls: New API to set a callback to extract TLS Finished data.
2166 The function to register is gnutls_session_set_finished_function and
2167 it takes a callback of the gnutls_finished_callback_func type.
2169 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
2171 *** libgnutls: New interface to register a new TLS extension handler.
2172 The new function gnutls_ext_register can be used to register handlers
2173 for specific TLS extension types. The callback functions have the new
2174 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
2175 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
2178 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
2179 The function is gnutls_register_md5_handler. When libgcrypt is in
2180 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
2183 *** API/ABI changes in GnuTLS 2.6
2184 No functions have been removed or modified. The library should be
2185 fully backwards compatible on both the source and binary level.
2187 A new header file <gnutls/crypto.h> have been added. It contains
2188 definitions related to replacing the internal crypto functionality.
2189 All definitions and the header itself is experimental but supported.
2191 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
2192 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
2193 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
2195 The following functions have been added to libgnutls:
2199 gnutls_crypto_bigint_register2

2240 ** doc: Texinfo HTML manual uses a stylesheet to improve readability.
2242 ** tests: Scripts now use EXEEXT properly.
2243 Modern libtool doesn't create wrapper script, so the self tests need
2244 to invoke certtool.exe under MinGW32+Wine.
2246 ** Uses autoconf 2.63, automake 1.10.1, libtool 2.2.6a.
2247 Automake warnings are now also enabled.

2259 such as IP addresses.
2261 ** libgnutls: Fix crash in hashing code when using non-libgcrypt handlers.
2263 ** libgnutls: New function to set minimum acceptable SRP bits.
2264 The function is gnutls_srp_set_prime_bits. Tiny patch by Kevin Quick

2345 ** libgnutls: Fix segmentation fault when generating private keys.
2346 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
2348 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
2349 The code has not worked since v0.9.0 and apparently nobody has missed
2350 it, so we decided to remove the code rather than fix it. If you have
2351 old certificate chains stored in PKCS#7 format, you can convert them
2352 to a list of PEM certificates by using 'certtool --p7-info'. Reported
2353 by Christian Grothoff <christian@grothoff.org>.

2382 ** libgnutls: New API to set the public parameters in a certificate request
2383 ** from a private key.
2384 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
2385 discussion with "Zach C." <fxchip@gmail.com>.
2387 ** libgnutls: New API to set a callback to extract TLS Finished data.
2388 The function to register is gnutls_session_set_finished_function and
2389 it takes a callback of the gnutls_finished_callback_func type.
2391 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
2392 Reported in <https://savannah.gnu.org/support/?106453>.
2394 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
2395 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
2396 names are mapped to the new names in compat.h. These mappings will
2397 likely be removed more quickly than other mappings in that file due to
2398 the namespace violation.
2400 ** libgnutlsxx: Make it build when SRP is disabled.
2402 ** doc: Add doxygen files in doc/doxygen/.

2410 TLS_MASTER_SIZE: DEPRECATED
2411 TLS_RANDOM_SIZE: DEPRECATED
2413 * Version 2.5.2 (released 2008-07-08)
2415 ** libgnutls: Fix bug in gnutls_dh_params_generate2.
2416 The prime and generator was swapped.
2418 ** libgnutls: New interface to register a new TLS extension handler.
2419 The new function gnutls_ext_register can be used to register handlers
2420 for specific TLS extension types. The callback functions have the new
2421 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
2422 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
2425 ** Move more code for TLS/IA extension from libgnutls to libgnutls-extra.
2426 This was made possible by using the new gnutls_ext_register interface.
2427 The TLS/IA functionality has only been supported through the
2428 libgnutls-extra library, so it makes sense for the code to belong

2446 ** Port fixes from v2.4.1 release, see below.
2448 ** Added API to replace and update the crypto backend.
2449 The header gnutls/crypto.h is now officially supported, and declares
2452 ** Rewritten opencdk crypto backend, to use the gnutls internal one.
2454 ** Update gnulib and translations.
2455 The gnulib gc crypto code has been removed since it was never finished
2456 and is no longer even used. An internal non-libgcrypt crypto
2457 implementation may be added in the future, but we'll decide that later

2471 * Version 2.4.3 (released 2009-02-06)
2473 ** libgnutls: Accept chains where intermediary certs are trusted.
2474 Before GnuTLS needed to validate the entire chain back to a
2475 self-signed certificate. GnuTLS will now stop looking when it has
2476 found an intermediary trusted certificate. The new behaviour is
2477 useful when chains, for example, contains a top-level CA, an
2478 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2479 To avoid chain validation errors due to the RSA-MD5 cert, you can
2480 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2481 The signature on trusted certificates are not checked, so the chain
2482 has a chance to validate correctly. Reported by "Douglas E. Engert"
2483 <deengert@anl.gov> in
2484 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.

2556 ** libgnutls: Fix local crash in gnutls_handshake. [GNUTLS-SA-2008-2]
2557 If the gnutls_handshake function is called for a normal session, which
2558 can happen for re-handshakes, the library would crash because it tried
2559 to hash some data using a libgcrypt handle that had been deallocated.
2560 Report and tiny patch from Tomas Mraz <tmraz@redhat.com>. Any updates
2561 with more details about this vulnerability will be added to

2580 ** API and ABI modifications:
2581 No changes since last version.
2583 * Version 2.4.0 (released 2008-06-19)
2585 ** Major changes compared to the v2.2 branch:
2587 *** The OpenPGP sub-system has been improved and now supports subkeys.
2589 *** The PSK sub-system has been improved and now supports password
2590 *** derivation and PSK identity hints.
2591 The password derivation algorithms support is documented in
2592 draft-ietf-netconf-tls-02.txt.
2594 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
2595 This aligns terminology with OpenPGP, which doesn't use DER encoding.
2596 The old parameters will continue to work for some time.
2598 *** Certtool now confirm passwords and changes permissions of private key files.
2600 *** The default handshake size limit has been increased to 48kb.
2601 It appears as if some valid handshakes are large due to sending many
2602 CA certificates. (The earlier limit was 16kb.)
2604 *** LZO compression is now disabled by default.
2605 The main reason is that LZO compression in TLS is not standardized,
2606 but license compatiblity issues with minilzo triggered us to make this
2609 *** Improvements for cross-compilation to Windows and OpenWRT.
2611 *** The look of the GTK-DOC manual has been improved.
2612 Major developer visible changes compared to the v2.2 branch:
2614 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
2616 *** New APIs to access the raw X.509 Subject and Issuer DN's and
2617 *** elements from the certificate credentials structure.
2618 Thanks to Joe Orton.
2620 *** New APIs to improve working with username/passwords and PSK.
2622 *** Names of constants to affect certificate printing changed.
2623 The constants are used for OpenPGP too, which the names didn't
2624 reflect, so the following name change has been made:
2627 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
2628 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
2629 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
2631 The old names will be mapped to the new names for some time.
2633 *** The function gnutls_openpgp_privkey_get_id has been renamed to
2634 *** gnutls_openpgp_privkey_get_key_id.
2635 A compatibility mapping exists to avoid breaking API backwards
2638 *** Replaced all uses of alloca with malloc and free.
2640 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
2641 We have been unable to find a documented rationale for this practice.
2643 *** Of course, many smaller fixes have been made, see the ChangeLog file.
2645 *** API/ABI changes in GnuTLS 2.4
2646 All OpenPGP related functions have been moved from libgnutls-extra to
2647 libgnutls, and several new functions have been added (see below).
2648 Before making the release, we discussed whether moving functions from
2649 libgnutls-extra to libgnutls would require us to increment the ABI
2650 version, but the general opinion was that this would not be required.
2651 All older functions continue to work the same. We are open to the
2652 possibility that this decision will lead to problem on some platform,
2653 and if it turns out that the Right Thing should have been to increment
2654 the shared library version, we would need to release an update within
2655 the 2.4.x branch that increments the shared library version.
2657 This release adds the following functions:
2659 gnutls_psk_client_get_hint
2660 gnutls_psk_set_server_credentials_hint
2661 gnutls_psk_netconf_derive_key
2663 Used to get/set the PSK identity hint, and derive PSK keys from
2664 passwords a'la netconf.
2666 gnutls_x509_dn_deinit
2667 gnutls_x509_dn_export
2668 gnutls_x509_dn_import
2671 Used to handle X.509 Certificate DN's directly.
2675 Converts a data buffer to hex. Useful for handling PSK/SRP shared
2678 gnutls_certificate_get_x509_cas
2679 gnutls_certificate_get_x509_crls
2680 gnutls_certificate_get_openpgp_keyring
2682 Functions for direct access to credential elements.
2684 gnutls_openpgp_crt_get_auth_subkey

2722 gnutls_openpgp_privkey_get_subkey_revoked_status
2723 gnutls_openpgp_privkey_set_preferred_key_id
2725 New OpenPGP related functions.
2727 The function gnutls_openpgp_crt_get_key_id is the same as the old
2728 from gnutls_openpgp_crt_get_id, see above.
2730 The release also adds a new header file 'gnutls/crypto.h', however it
2731 is currently not used.
2733 ** libgnutls [OpenPGP]: New APIs to retrieve fingerprint from OpenPGP subkeys.
2734 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
2736 ** API and ABI modifications:
2737 gnutls_openpgp_crt_get_subkey_fingerprint: ADDED.
2738 gnutls_openpgp_privkey_get_subkey_fingerprint: ADDED.
2740 * Version 2.3.15 (released 2008-06-15)
2742 ** Disable the openpgp-certs self-tests.
2743 It results in failure under Wine and doesn't work on Debian buildds.

2751 An OpenPGP certificate is now only considered verified if all the user
2754 ** Examples: Make C++ example compile.
2755 Earlier it may have failed with an unresolved reference to strlen.
2757 ** Documentation: Doc fix for gnutls_x509_crt_get_extension_oid.
2758 Reported by Sam Varshavchik <mrsam@courier-mta.com>.
2760 ** API and ABI modifications:
2761 No changes since last version.
2763 * Version 2.3.13 (released 2008-06-07)
2765 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
2767 ** doc/: Add psktool to info index. Some minor cleanups.
2769 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
2771 ** tests/: Added libgcrypt.supp which can be used with valgrind.
2772 The file suppresses the known libgcrypt memory leaks, so they aren't
2773 printed when you run valgrind on the gnutls self-tests. Use it as
2774 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add
2775 '--suppressions=/home/you/src/gnutls/tests/libgcrypt.supp' to your
2778 ** tests/: Reduce amount of debugging output by default.
2779 Use --verbose for each test to get the full output.
2781 ** tests/: Fix memory leaks in several self-tests.
2782 None of the self tests should be leaking memory when running valgrind
2783 or similar tools. (Known exceptions are dhepskself, pskself, and
2784 set_pkcs12_cred, which appear likely to be due to memory leaks in the

2788 No changes since last version.
2790 * Version 2.3.12 (released 2008-06-04)
2792 ** Merge gnutls_with_netconf branch.
2794 *** libgnutls [PSK]: New API to retrieve PSK identity hint in client.
2795 The function is gnutls_psk_client_get_hint.
2797 *** libgnutls [PSK]: New API to set PSK identity hint in server.
2798 The function is gnutls_psk_set_server_credentials_hint.
2800 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
2801 In the client, the message is parsed and the application can use
2802 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
2803 message is sent if the application has specified a PSK identity hint
2804 using gnutls_psk_set_server_credentials_hint.
2806 *** libgnutls [PSK]: Support Netconf PSK key derivation.
2807 The function gnutls_psk_netconf_derive_key supports the PSK key
2808 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
2811 *** psktool: Support new --netconf-hint to generate PSK key from password.
2812 Uses the Netconf algorithm to derive PSK key from password.
2814 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
2816 *** gnutls-cli: Always support PSK modes, through a callback.
2817 The callback will derive a PSK key using Netconf algorithm. It will
2818 print the PSK identity hint to help the user.
2820 *** New PSK example client and server.
2821 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
2823 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.
2824 The code didn't work properly on platforms where 'char' is unsigned,
2825 when you set version 0. Reported by Laurence Withers
2826 <l@lwithers.me.uk> in
2827 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2825>.
2829 ** libgnutls-openssl: added RAND_pseudo_bytes API.
2830 Patch from Robert Millan <rmh@aybabtu.com>.
2832 ** API and ABI modifications:
2833 RAND_pseudo_bytes: ADDED to libgnutls-openssl.
2834 gnutls_psk_client_get_hint: ADDED.
2835 gnutls_psk_set_server_credentials_hint: ADDED.
2836 gnutls_psk_netconf_derive_key: ADDED
2838 * Version 2.3.11 (released 2008-05-20)
2840 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
2841 The flaw would result in incorrectly terminated sessions with the
2842 error "Decryption has failed" when the server sends a small packet
2843 (typically when the session is closed). Reported by Andreas Metzler

2847 ** Don't use gnulib headers when building C++ library.
2848 Fixes builds under Windows.
2850 ** Make umask a requirement.
2851 We don't know of any system that lacks it, even GNU CoreUtils use it
2854 ** Update gnulib files.
2855 Fixes a problem where it pulled in a replacement for memcmp under
2856 MinGW, which caused the C++ example to fail to build.
2858 ** API and ABI modifications:
2859 No changes since last version.
2861 * Version 2.3.10 (released 2008-05-19)
2863 ** Added wide wildcard hostname matching.
2864 Tiny patch by Jean-Philippe Garcia Ballester.
2866 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
2867 Thanks to CERT-FI for finding the bugs and providing detailed reports,
2868 which allowed the bugs to be reproduced and fixed easily. Patches
2869 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
2870 with more details about these vulnerabilities will be added to

2873 *** [GNUTLS-SA-2008-1-1]
2874 *** libgnutls: Fix crash when sending invalid server name.
2875 The crash can be triggered remotely before authentication, which can
2876 lead to a Daniel of Service attack to disable the server. The bug
2877 cause gnutls to store more session resumption data than what was
2878 allocated for, thus overwriting unallocated memory.
2880 *** [GNUTLS-SA-2008-1-2]
2881 *** libgnutls: Fix crash when sending repeated client hellos.
2882 The crash can be triggered remotely before authentication, which can
2883 lead to a Daniel of Service attack to disable the server. The bug
2884 triggers a null-pointer dereference.
2886 *** [GNUTLS-SA-2008-1-3]
2887 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
2888 The crash can be triggered remotely before authentication, which can
2889 lead to a Daniel of Service attack to disable the server. The bug
2890 cause gnutls to read memory beyond the end of the received record.
2892 ** libgnutlsxx: Updated API according to patches from Eduardo
2893 Villanueva Che (discussion at
2894 <http://lists.gnu.org/archive/html/gnutls-devel/2007-02/msg00017.html>)
2896 ** Use umask to restrict permissions to owner before creating a file.
2898 ** API and ABI modifications:
2899 No changes since last version.
2901 * Version 2.3.9 (released 2008-05-16)
2903 ** libgnutls: Fix build failures if SRP/OpenPGP is disabled.
2904 Based on report and tiny patches from
2905 <jared.jennings.ctr@eglin.af.mil>, see
2906 <https://savannah.gnu.org/support/index.php?106342>.
2908 ** libgnutls: Translation fixes.
2910 ** gnutls-cli: Fix so that PSK authentication works.
2911 Also improve manual to give example for gnutls-cli PSK authentication.
2913 ** certtool: Encrypting a private key now require a confirmed password.
2914 Before './certtool -k -8' would merely ask for a password once.
2915 Reported by Daniel 'NebuchadnezzaR' Dehennin
2916 <nebuchadnezzar@asgardr.info> see
2917 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
2919 ** certtool: When writing private keys to files, change permissions of file.
2920 Now the file which the private key is saved to is chmod'ed 0600.
2921 Reported by martin f krafft <madduck@debian.org> see
2922 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
2924 ** guile: Fix -fgnu89-inline test.
2926 ** Removed --enable-profile-mode.
2927 The code linked gnutls with the libfc project (Function Check) which
2928 appears to have been stalled since around 2002.
2930 ** Clean up header file checks by ./configure.
2932 ** Update of gnulib files.
2934 ** API and ABI modifications:
2935 No changes since last version.
2937 * Version 2.3.8 (released 2008-04-29)
2939 ** libgnutls: Increase default handshake packet size limit to 48kb.
2940 The old limit was 16kb and some servers send huge list of trusted CAs,
2941 thus running into the limit. FYI, applications can further increase
2942 this limit using gnutls_handshake_set_max_packet_length. Thanks to
2943 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
2944 <marc@mclemente.net> for reporting and providing test servers.
2946 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
2947 Returned when the handshake data size is too large. Before
2948 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
2951 ** libgnutls: Hide definitions in crypto.h.
2952 We have decided that the APIs defined in crypto.h are not stable
2953 enough for v2.4, so don't use any of those functions.
2955 ** gnutls-cli: exit when hostname doesn't match certificate.
2956 Use --insecure to avoid hostname comparison.
2958 ** certtool: --inder and --outder replaced by --inraw and --outraw.
2959 The reason is to align terminology with OpenPGP, which doesn't use
2960 DER. The old parameters will continue to work for some time.
2962 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
2964 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
2966 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
2967 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
2968 vasprintf symbol from the libgcrypt library which caused problems.
2970 ** Update of gnulib files.
2972 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
2974 ** API and ABI modifications:
2975 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
2977 * Version 2.3.7 (released 2008-04-21)
2979 ** opencdk now properly sets the key usage bits into openpgp keys.
2981 ** gnutls-cli: Fix crash on TLS handshake failures.
2982 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
2983 This is similar to <http://bugs.debian.org/429183>.
2985 ** certtool: with --generate-request and newly generated keys, print the key.
2987 ** Build fixes for MinGW.
2988 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
2989 with -lws2_32 when needed. Use ASCII only isprint() when printing
2990 X.509 certificate information, to avoid non-ASCII but printable
2991 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
2994 ** Update internal copy of libtasn1 to version 1.4.
2996 ** API and ABI modifications:
2997 No changes since last version.
2999 * Version 2.3.6 (released 2008-04-17)
3001 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
3002 ** Improve documentation for gnutls_x509_crq_sign2.
3003 Based on report from "John Brooks" <aspecialj@gmail.com> in

3014 ** Remove all uses of gnutls_alloca/gnutls_afree.
3015 Use normal gnutls_malloc instead. One reason is increased portability
3016 to Windows, the other is that several of the uses may be unsafe
3017 because the size of data allocated could be large. Reported by
3018 Massimo Gaspari <massimo.gaspari@alice.it> in

3065 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
3066 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
3067 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
3068 gnutls_crypto_rnd_st: ADDED
3069 GNUTLS_DIG_SHA224: ADDED
3070 GNUTLS_SIGN_RSA_SHA224: ADDED
3071 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
3073 * Version 2.3.4 (released 2008-03-19)
3075 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
3076 They weren't renamed in the public header file.
3078 ** Added functions to register a cipher/mac/digest. This allows to
3079 override the included ones.
3081 ** Fix a bunch of compiler warnings.
3083 ** API and ABI modifications:
3084 gnutls_crypto_cipher_st: ADDED
3085 gnutls_crypto_mac_st: ADDED
3086 gnutls_crypto_digest_st: ADDED
3087 gnutls_crypto_cipher_register: ADDED
3088 gnutls_crypto_mac_register: ADDED
3089 gnutls_crypto_digest_register: ADDED
3090 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
3092 * Version 2.3.3 (released 2008-03-10)
3094 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
3095 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
3097 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
3098 We could not find any modern justification for enabling these flags by
3099 default. If you know of some platform that needs one of the flags to
3100 work properly, please let us know. (Actually introduced in v2.3.0 but
3101 not documented until now.)
3103 ** Importing many CA certificates are now considerably faster.
3104 This affect gnutls_certificate_set_x509_trust_mem,
3105 gnutls_certificate_set_x509_trust, and
3106 gnutls_certificate_set_x509_trust_file. The complexity was reduced
3107 from O(2*n^2) to O(n). When adding 206 files containing 408
3108 certificates, using gnutls_certificate_set_x509_trust_file, the time
3109 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
3110 to trigger the problem. See also
3111 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
3113 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
3114 ** to be explicit that it takes zero terminated data.
3116 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.
3118 ** Documentation fixes for the GTK-DOC manual.
3120 ** Fix compilation error related to __FUNCTION__ on some systems.
3121 Reported by Tim Mooney, see
3122 <https://savannah.gnu.org/support/?106267>.
3124 ** Updated translations.
3126 ** Update gnulib files.
3128 ** API and ABI modifications:
3129 gnutls_hex2bin: MODIFIED, uses size_t instead of int for string length,
3130 and char* instead of void* for output buffer.
3132 * Version 2.3.2 (released 2008-02-26)
3134 ** Fix srcdir!=objdir failure in openpgpself test.
3136 ** Improved API documentation output from GTK-DOC.
3138 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
3140 ** Renamed gnutls_certificate_export_x509_cas and friends.
3141 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.
3143 ** Internal header files cleanup.
3145 ** API and ABI modifications:
3146 gnutls_certificate_export_x509_cas: RENAMED to gnutls_certificate_get_x509_cas
3147 gnutls_certificate_export_x509_crls: RENAMED to gnutls_certificate_get_x509_crls
3148 gnutls_certificate_export_openpgp_keyring: RENAMED to gnutls_certificate_get_openpgp_keyring
3149 gnutls_x509_dn_export: ADDED
3151 * Version 2.3.1 (released 2008-02-21)
3153 ** OpenPGP support merged into libgnutls and is now licensed under LGPL.
3154 The included copy of OpenCDK has been stripped down and re-licensed
3157 ** Cipher priority string handling now handle strings that starts with NULL.
3158 Thanks to Laurence Withers <l@lwithers.me.uk>.
3160 ** gnutls-cli: When -d is used, also prints RNG information from libgcrypt.
3162 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
3165 ** Increased the default certificate verification chain limits and allowed
3166 for checks without limitation.
3168 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
3169 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
3170 strings and return the proper size.
3172 ** Add section 'On Record Padding' to the manual.
3173 This collects all problems related to record padding with
3174 Nokia/Sony-Ericsson phones that we know about.
3176 ** Several improvements in the OpenPGP authentication.
3177 Now subkeys can be used for authentication, according to
3178 draft-mavrogiannopoulos-rfc5081bis-00.txt.
3180 ** certtool can print information on OpenPGP certificates and keys.
3182 ** Added gnutls_x509_dn_import/init/deinit() to access raw DER DN.
3185 ** Added gnutls_certificate_export_x509_cas and other functions to
3186 export elements from the certificate credentials structure. Based on
3187 suggestion from Joe Orton.
3190 Clarify that srp_base64 is not the same as normal base64.
3192 ** Fix non-portable use of brace expansion in makefiles.
3194 ** API and ABI modifications:
3195 gnutls_certificate_export_x509_cas: ADDED
3196 gnutls_certificate_export_x509_crls: ADDED
3197 gnutls_certificate_export_openpgp_keyring: ADDED
3198 gnutls_openpgp_keyid_t: ADDED, instead of hard-coded 'unsigned char[8]'.
3199 gnutls_openpgp_crt_get_key_id: ADDED, obsoletes gnutls_openpgp_crt_get_id.
3200 gnutls_openpgp_crt_get_revoked_status: ADDED
3201 gnutls_openpgp_crt_get_subkey_count: ADDED
3202 gnutls_openpgp_crt_get_subkey_idx: ADDED
3203 gnutls_openpgp_crt_get_subkey_revoked_status: ADDED
3204 gnutls_openpgp_crt_get_subkey_pk_algorithm: ADDED
3205 gnutls_openpgp_crt_get_subkey_creation_time: ADDED
3206 gnutls_openpgp_crt_get_subkey_expiration_time: ADDED
3207 gnutls_openpgp_crt_get_subkey_id: ADDED

3235 GNUTLS_CRT_PRINT_FULL: ADDED, same as old GNUTLS_X509_CRT_FULL.
3236 GNUTLS_CRT_PRINT_ONELINE: ADDED, same as old GNUTLS_X509_CRT_ONELINE.
3237 GNUTLS_CRT_PRINT_UNSIGNED_FULL: ADDED, same as
3238 old GNUTLS_X509_CRT_UNSIGNED_FULL.
3240 * Version 2.3.0 (released 2008-01-08)
3242 ** LZO compression is now disabled by default.
3243 The reason is that LZO compression is not standardized in TLS. If you
3244 wish to experiment with it, you will have to supply --with-lzo when
3245 invoking ./configure. The internal copy of minilzo is no longer
3246 included with GnuTLS, so you will need to install liblzo or liblzo2 on
3247 your system to have --with-lzo to be effective.
3249 ** More than one server name field is now sent to the server properly.
3250 Thanks to mark.phillips@virgin.net.
3252 ** Fixes the post_client_hello_function(). The extensions are now parsed
3253 in a callback friendly way.
3255 ** Fix for certificate selection in servers with certificate callbacks.
3257 ** Updated translations.
3259 ** Update gnulib files.
3261 ** API and ABI modifications:
3262 No changes since last version.
3264 * Version 2.2.5 (released 2008-05-19)
3266 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
3267 The flaw would result in incorrectly terminated sessions with the
3268 error "Decryption has failed" when the server sends a small packet
3269 (typically when the session is closed). Reported by Andreas Metzler
3270 <ametzler@downhill.at.eu.org> in
3271 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
3273 ** API and ABI modifications:
3274 No changes since last version.
3276 * Version 2.2.4 (released 2008-05-19)
3278 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
3279 Thanks to CERT-FI for finding the bugs and providing detailed reports,
3280 which allowed the bugs to be reproduced and fixed easily. Patches
3281 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
3282 with more details about these vulnerabilities will be added to
3283 <http://www.gnu.org/software/gnutls/security.html>
3285 *** [GNUTLS-SA-2008-1-1]
3286 *** libgnutls: Fix crash when sending invalid server name.
3287 The crash can be triggered remotely before authentication, which can
3288 lead to a Daniel of Service attack to disable the server. The bug
3289 cause gnutls to store more session resumption data than what was
3290 allocated for, thus overwriting unallocated memory.
3292 *** [GNUTLS-SA-2008-1-2]
3293 *** libgnutls: Fix crash when sending repeated client hellos.
3294 The crash can be triggered remotely before authentication, which can
3295 lead to a Daniel of Service attack to disable the server. The bug
3296 triggers a null-pointer dereference.
3298 *** [GNUTLS-SA-2008-1-3]
3299 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3300 The crash can be triggered remotely before authentication, which can
3301 lead to a Daniel of Service attack to disable the server. The bug
3302 cause gnutls to read memory beyond the end of the received record.
3304 ** API and ABI modifications:
3305 No changes since last version.
3307 * Version 2.2.3 (released 2008-05-06)
3309 ** Increase default handshake packet size limit to 48kb.
3310 The old limit was 16kb and some servers send huge list of trusted CAs,
3311 thus running into the limit. FYI, applications can further increase
3312 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3313 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3314 <marc@mclemente.net> for reporting and providing test servers.
3316 ** Fix compilation error related to __FUNCTION__ on some systems.
3317 Reported by Tim Mooney, see
3318 <https://savannah.gnu.org/support/?106267>.
3320 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3322 ** Fix fopen file descriptor leak in PSK server code.
3323 Thanks to Laurence Withers <l@lwithers.me.uk>, see
3324 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
3326 ** Build Guile code with -fgnu89-inline only when supported.
3327 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
3328 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
3330 ** Make Camellia encryption work.
3331 Reported by Yoshisato YANAGISAWA <yanagisawa@csg.is.titech.ac.jp> in
3332 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2746>.
3334 ** API and ABI modifications:
3335 No changes since last version.
3337 * Version 2.2.2 (released 2008-02-21)
3339 ** Cipher priority string handling now handle strings that starts with NULL.
3340 Thanks to Laurence Withers <l@lwithers.me.uk>.
3342 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
3345 ** Increased the default certificate verification chain limits and allowed
3346 for checks without limitation.
3348 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
3349 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
3350 strings and return the proper size.
3352 ** API and ABI modifications:
3353 No changes since last version.
3355 * Version 2.2.1 (released 2008-01-17)
3357 ** Prevent linking libextra against previously installed libgnutls.
3358 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
3359 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
3361 ** Fixes the post_client_hello_function(). The extensions are now parsed
3362 in a callback friendly way.
3364 ** Fix for certificate selection in servers with certificate callbacks.
3366 ** API and ABI modifications:
3367 No changes since last version.
3369 * Version 2.2.0 (released 2007-12-14)
3371 ** Update internal copy of libtasn1 to version 1.2.
3373 ** Certtool --verify-chain now handle inputs larger than 64kb.
3374 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
3375 recent versions of libgcrypt. The problem was that Wine with the
3376 libgcrypt RNG generates huge amounts of debugging output.
3378 ** Translation updates.
3379 Added Dutch translation. Updated Polish and Swedish translation.
3381 ** Major changes compared to the v2.0 branch:
3383 *** SRP support aligned with newly published RFC 5054.
3385 *** OpenPGP support aligned with newly published RFC 5081.
3387 *** Support for DSA2 keys.
3389 *** Support for Camellia cipher.
3391 *** Support for Opaque PRF Input extension.
3393 *** PKCS#8 parser now handle DSA keys.
3395 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
3396 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
3397 versions, such as 2.01 which is included with GnuTLS, is available
3398 under GPLv2 or later. If this incompatibility causes problems, we
3399 recommend you to disable LZO using --without-lzo. LZO compression is
3400 not a standard TLS compression algorithm, so the impact should be
3403 *** Functions for disabling record protocol padding.
3404 Works around bugs on Nokia/Ericsson phones.
3406 *** New functions gnutls_priority_set() for setting cipher priorities easily.
3407 Priorities like "COMPAT" also enables other work arounds, such as
3410 *** Other minor improvements and bug fixes.
3412 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
3413 To adapt to changes in the TLS extension specifications for OpenPGP
3414 and SRP, the GnuTLS API had to be modified. This means breaking the
3415 API and ABI backwards compatibility. That is something we try to
3416 avoid unless it is necessary. We decided to also remove the already
3417 deprecated stub functions for X.509 to XML conversion and TLS
3418 authorization (see below) when we had the opportunity.
3420 Generally, most applications does not need to be modified. Just
3421 re-compile them against the latest GnuTLS release, and it should work
3424 Applications that use the OpenPGP or SRP features needs to be
3425 modified. Below is a list of the modified APIs and discussion of what
3426 the minimal things you need to modify in your application to make it
3427 work with GnuTLS 2.2.
3429 Note that GnuTLS 2.2 also introduces new APIs -- such as
3430 gnutls_set_priority() that is superior to
3431 gnutls_set_default_priority() -- that you may want to start using.
3432 However, using those new APIs is not required to use GnuTLS 2.2 since
3433 the old functions continue are still supported. This text only
3434 discuss what you minimally have to modify.
3436 *** XML related changes
3437 The function `gnutls_x509_crt_to_xml' has been removed. It has been
3438 deprecated and only returned an error code since GnuTLS version
3439 1.2.11. Nobody has complained, so users doesn't seem to miss the
3440 functionality. We don't know of any other library to convert X.509
3441 certificates into XML format, but we decided (long ago) that GnuTLS
3442 isn't the right place for this kind of functionality. If you want
3443 help to find some other library to use here, please explain and
3444 discuss your use case on help-gnutls@gnu.org.
3446 *** TLS Authorization related changes
3447 Everything related to TLS authorizations have been removed, they were
3448 only stub functions that returned an error code:
3450 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
3451 gnutls_authz_data_format_type_t
3452 gnutls_authz_recv_callback_func
3453 gnutls_authz_send_callback_func
3455 gnutls_authz_send_x509_attr_cert
3456 gnutls_authz_send_saml_assertion
3457 gnutls_authz_send_x509_attr_cert_url
3458 gnutls_authz_send_saml_assertion_url
3460 *** SRP related changes
3461 The callback gnutls_srp_client_credentials_function has a new
3462 prototype, and its semantic has changed. You need to rewrite the
3463 callback, see the updated function documentation and SRP example code
3464 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
3467 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
3468 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
3469 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
3470 used. There are #define's to map the old names to the new. You may
3471 run into problems if you have a switch-case with cases for both SRP
3472 alerts, since they are now mapped to the same value. The solution is
3473 to drop the SRP alerts from such switch cases, as they are now
3474 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
3476 *** OpenPGP related changes
3477 The function `gnutls_certificate_set_openpgp_keyserver' have been
3478 removed. There is no replacement functionality inside GnuTLS. If you
3479 need keyserver functionality, consider using the GnuPG tools.
3481 All functions, types, and error codes related to OpenPGP trustdb
3482 format have been removed. The trustdb format is a non-standard
3483 GnuPG-specific format, and we recommend you to use key rings instead.
3484 The following have been removed:
3486 gnutls_certificate_set_openpgp_trustdb
3487 gnutls_openpgp_trustdb_init
3488 gnutls_openpgp_trustdb_deinit
3489 gnutls_openpgp_trustdb_import
3490 gnutls_openpgp_key_verify_trustdb
3491 gnutls_openpgp_trustdb_t
3492 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
3494 The following functions has an added parameter of the (new) type
3495 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
3496 (binary or base64). The functions are:
3497 gnutls_certificate_set_openpgp_key_file
3498 gnutls_certificate_set_openpgp_key_mem
3499 gnutls_certificate_set_openpgp_keyring_mem
3500 gnutls_certificate_set_openpgp_keyring_file
3502 To improve terminology and align with the X.509 interface, some
3503 functions have been renamed. Compatibility mappings exists. The old
3504 and new names of the affected functions and types are:
3507 gnutls_openpgp_key_t gnutls_openpgp_crt_t
3508 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
3509 gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
3510 GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
3511 GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
3512 gnutls_openpgp_key_init gnutls_openpgp_crt_init
3513 gnutls_openpgp_key_deinit gnutls_openpgp_crt_deinit

3551 ** Updated gnutls_set_default_priority2() now renamed to
3552 gnutls_priority_set() and gnutls_priority_set_direct() which
3553 accept a string to indicate preferences of ciphersuite parameters.
3555 ** gnutls-cli and gnutls-serv now have a --priority option to set
3556 the priority string.
3558 ** The gnutls_*_convert_priority() functions were deprecated by
3559 the gnutls_priority_set() and gnutls_priority_set_direct().
3561 ** Internal copy of OpenCDK upgraded to version 0.6.6.
3563 ** API and ABI modifications:
3564 gnutls_priority_init: ADD.
3565 gnutls_priority_deinit: ADD.
3566 gnutls_priority_set: ADD.
3567 gnutls_priority_set_direct: ADD.

3574 gnutls_certificate_type_convert_priority: REMOVED
3575 gnutls_set_default_priority: UNDEPRECATED
3576 gnutls_set_default_priority_export: UNDEPRECATED
3578 ** Undocumented API and ABI modifications earlier in the 2.1.x series:
3579 GNUTLS_CIPHER_UNKNOWN: ADD.
3580 GNUTLS_CIPHER_CAMELLIA_128_CBC: ADD.
3581 GNUTLS_CIPHER_CAMELLIA_256_CBC: ADD.

3592 gnutls_certificate_send_x509_rdn_sequence: ADD prototype to gnutls.h.in.
3594 * Version 2.1.6 (released 2007-11-15)
3596 ** Corrected bug in decompression of expanded compression data.
3598 ** Added the --to-p8 option to certtool to convert private keys
3601 ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code.
3603 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
3606 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
3607 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
3608 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
3609 documented. This caused some problems (e.g., debian #450854). To
3610 avoid backwards compatibility problems, this release revert this
3611 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
3612 done in GnuTLS 2.0.x and earlier, and add a new error code
3613 GNUTLS_E_UNKNOWN_ALGORITHM.
3615 ** Fixes several gtk-doc warnings.
3617 ** API and ABI modifications:
3618 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
3619 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
3620 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
3622 * Version 2.1.5 (released 2007-11-01)
3624 ** Fix PKCS#3 parameter export problem.
3626 ** Improve certtool queries, they now print the default value.
3630 ** Update gnulib files.
3632 ** API and ABI modifications:
3633 No changes since last version.
3635 * Version 2.1.4 (released 2007-10-27)
3637 ** Added the --v1 option to certtool, to allow generating X.509
3638 version 1 certificates.
3640 ** certtool: Add option --disable-quick-random to enable the old behaviour
3641 of using /dev/random to generate keys.
3643 ** Added priority functions that accept strings.
3645 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
3646 priorities preferences.
3648 ** Added gnutls_record_disable_padding() to allow servers talking to
3649 buggy clients that complain if the TLS 1.0 record protocol padding is
3652 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
3653 all supported compatibility options (like disabling padding).
3655 ** The gnutls_certificate_set_openpgp_* functions were modified to include
3656 the format. This makes the interface consistent with the x509 functions.
3658 ** Internal copy of OpenCDK upgraded to version 0.6.5.

3697 * Version 2.1.3 (released 2007-10-17)
3699 ** TLS authorization support removed.
3700 This technique may be patented in the future, and it is not of crucial
3701 importance for the Internet community. After deliberation we have
3702 concluded that the best thing we can do in this situation is to
3703 encourage society not to adopt this technique. We have decided to
3704 lead the way with our own actions.
3706 ** Re-enabled the 256 bit ciphers in the default priorities.
3708 ** Corrected bugs in openpgp key verification using a keyring (both in

3721 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
3722 gnutls_supplemental_data_format_type_t enum type becomes empty.
3724 * Version 2.1.2 (released 2007-10-14)
3726 ** Removed all the trustdb code from openpgp authentication.
3727 We now use only the well-specified keyrings.
3729 ** The 256 bit ciphers are not enabled in the default priorities.
3731 ** Added support for DSA2 using libgcrypt 1.3.0.
3733 ** certtool: Fixed data corruption when using --outder.
3735 ** Removed all the xml related stubs and functions.
3737 ** Added capability to set a callback after the client hello is received
3738 by the server in order to adjust parameters before the handshake.
3740 ** SRP was corrected to adhere to the latest draft (published soon as RFC)
3742 ** Corrected bug which did not allow a server to run without supporting
3745 ** Updated the DN parser which now prints wrongly decoded values as hex
3748 ** certtool: Add option --quick-random.

3764 GNUTLS_A_UNKNOWN_SRP_USERNAME: DEPRECATED
3766 * Version 2.1.1 (released 2007-09-24)
3768 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
3769 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
3770 compiled with Camellia support. See the libgcrypt documentation on
3771 how to enable it. Unconditionally disable it using the configure
3772 option --disable-camellia. Fixes #1.
3774 ** Properly document in the NEWS file the API change in the last release.
3776 ** API and ABI modifications:
3777 No changes since last version.
3779 * Version 2.1.0 (released 2007-09-20)
3781 ** Support for draft-rescorla-tls-opaque-prf-input-00.txt.
3782 The support is disabled by default. Since no value has been allocated
3783 by the IANA for this extension yet, you will need to provide one
3784 yourself by invoking './configure --enable-opaque-prf-input=42'.
3787 ** Example code: Fix compilation flaw under MinGW.
3789 ** API and ABI modifications:
3790 gnutls_oprfi_callback_func: ADD, new typedef function prototype.
3791 gnutls_oprfi_enable_client: ADD, new function.
3792 gnutls_oprfi_enable_server: ADD, new function.
3794 * Version 2.0.4 (released 2007-11-16)
3796 ** Corrected bug in decompression of expanded compression data.
3798 ** API and ABI modifications:
3799 No changes since last version.
3801 * Version 2.0.3 (released 2007-11-10)
3803 ** This version backports several fixes from the 2.1.x branch.
3805 ** Fixed PKCS #3 parameter export.
3807 ** Added gnutls_record_disable_padding() to allow servers talking to
3808 buggy clients that complain if the TLS 1.0 record protocol padding is

3821 * Version 2.0.2 (released 2007-10-17)
3823 ** TLS authorization support removed.
3824 This technique may be patented in the future, and it is not of crucial
3825 importance for the Internet community. After deliberation we have
3826 concluded that the best thing we can do in this situation is to
3827 encourage society not to adopt this technique. We have decided to
3828 lead the way with our own actions.
3830 ** certtool: Fixed data corruption when using --outder.
3832 ** Fix configure-time Guile detection.
3834 ** API and ABI modifications:
3835 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
3836 gnutls_supplemental_data_format_type_t enum type becomes empty.
3838 * Version 2.0.1 (released 2007-09-20)
3840 ** New directory doc/credentials/ with test credentials.
3841 This collects the test credentials from the web page and from src/.
3842 The script gnutls-http-serv has also been moved to that directory.
3844 ** Update SRP extension type and cipher suite with official IANA values.
3845 This breaks backwards compatibility with SRP in older versions of
3846 GnuTLS, but this is intentional to speed up the adoption of the
3847 official values. The old values we used were incorrect.
3849 ** Guile: Fix `x509-certificate-dn-oid'
3851 ** API and ABI modifications:
3852 No changes since last version.
3854 * Version 2.0.0 (released 2007-09-04)
3856 ** Included copy of Libtasn1 upgraded to version 1.1.
3858 ** Disable building of some examples if anonymous ciphers are disabled.
3860 ** Don't build examples for disabled features.
3862 ** API and ABI modifications:
3863 No changes since last version.
3865 * Version 1.7.19 (released 2007-08-27)
3867 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
3868 This solves connection problems in mutt, see
3869 <http://bugs.debian.org/439640>.
3871 ** Update gnulib files.
3872 In particular, the getpass module -- with its dependencies on getline,
3873 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
3874 library) directory to the gl/ directory (only used by the command line
3875 tools). The reason is that getpass is now only used by the
3876 command-line tools, and reducing the number of gnulib modules linked
3877 to the core library helps portability and reduces size.
3881 ** Disable building of PGP examples if PGP is disabled.
3883 ** Included copy of OpenCDK upgraded to version 0.6.4.
3885 ** API and ABI modifications:
3886 No changes since last version.
3888 * Version 1.7.18 (released 2007-08-16)
3890 ** Install images for the info manual.
3891 This has a side effect of renaming the images. See
3892 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
3893 discussions on the approach chosen.
3895 ** Fix pointer mix to variables of different size.
3896 Patch extracted from
3897 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
3899 ** Fix warnings during build.
3900 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
3902 ** API and ABI modifications:
3903 No changes since last version.
3905 * Version 1.7.17 (released 2007-08-15)
3907 ** New functions to perform external signing.
3908 Set the signing callback function (of the gnutls_sign_func prototype)
3909 using the gnutls_sign_callback_set function. In the callback, you may
3910 find the new functions gnutls_x509_privkey_sign_hash and
3911 gnutls_openpgp_privkey_sign_hash useful. A new function
3912 gnutls_sign_callback_get is also added, to retrieve the function
3913 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
3914 comments and testing.
3916 ** New self test of client and server authenticated X.509 TLS sessions.
3917 See tests/x509self.c and tests/x509signself.c. The latter also tests
3918 the new external signing callback interface.
3920 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
3921 These two actually describe the outer limits of a range of error codes
3922 reserved to the application. All of the errors are treated as fatal
3923 by the library (it has to since it doesn't know the semantics of the
3924 error codes). This can be useful in callbacks, to signal some
3925 application-specific error condition, which will usually eventually
3926 cause some gnutls API to return the same error code as the callback,
3927 which then can be inspected by the application. Note that error codes
3930 ** gnutls_set_default_priority now disable TLS 1.2 by default.
3931 The RFC is not released yet, and we're approaching a major release so
3932 let's not enable it just yet.
3934 ** Fix namespace so that gnutls_*_t is used consistently.
3935 Before, many places in the GnuTLS code used the old deprecated type
3936 names without the '_t' suffix.
3938 ** Build fixes for Guile code.
3939 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
3941 ** More documentation fixes.
3942 In particular, the section headings were modified for casing. By
3943 Ludovic Courtes <ludovic.courtes@laas.fr>.
3945 ** Updated Polish and Swedish translations.
3946 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
3947 <po@danielnylander.se>.
3949 ** API and ABI modifications:
3950 gnutls_sign_func: ADD, new type for sign callback.
3951 gnutls_sign_callback_set: ADD, new function to set sign callback.
3952 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
3953 gnutls_x509_privkey_sign_hash,
3954 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
3955 GNUTLS_E_APPLICATION_ERROR_MIN,
3956 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
3958 * Version 1.7.16 (released 2007-08-07)
3960 ** Fix sanity checks and return values in certificate selection.
3961 In some cases, GnuTLS omitted to report suitable error codes when no
3962 suitable certificate was found.
3964 ** Fix gnutls-cli starttls EOF on Mac OS X.
3965 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
3967 ** Documentation fixes.
3968 In particular, the section headings were modified for casing. By

3974 No changes since last version.
3976 * Version 1.7.15 (released 2007-07-02)
3978 ** Fix self-tests key-id under mingw32.
3980 ** Test that the Guile header files are recent enough to work.
3981 Before we just tested that the command line tool 'guile' was recent
3982 enough, which may not be sufficient if you still have an old
3983 libguile.h header installed.
3985 ** Guile bindings are now installed under $prefix by default.
3986 Use --without-guile-site-dir to install it under $pkgdatadir/site/
3987 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
3988 Use --with-guile-site-dir=/your/own/path to specify the path manually.
3989 The default, --with-guile-site-dir, will install the Guile bindings
3990 under $datadir/guile/site. There is a new section 'Guile
3991 Preparations' in the manual that discuss these issues.
3993 ** Fix run-time library path ordering in linking the Guile bindings.
3995 ** Improved manual on downloading, installing, getting help, bug reports etc.
3996 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
3998 ** Add Malay message translations.

4076 ** Include opencdk.h in the release.
4077 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
4079 ** API and ABI modifications:
4080 No changes since last version.
4082 * Version 1.7.10 (released 2007-05-25)
4084 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
4085 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
4087 ** Update of gnulib files.
4089 ** GnuTLS is now developed in GIT instead of CVS.
4090 See <http://repo.or.cz/w/gnutls.git> for a public repository.
4092 ** API and ABI modifications:
4093 gnutls_x509_crt_get_raw_issuer_dn: ADD.
4094 gnutls_x509_crt_get_raw_dn: ADD.
4096 * Version 1.7.9 (released 2007-05-12)
4098 ** X.509 certificates are preferred over OpenPGP keys.
4099 This is a change in the semantics of gnutls_set_default_priority.
4101 ** The included copy of OpenCDK has been updated to 0.6.1.
4102 There has been some API changes in OpenCDK, and the GnuTLS layer have
4103 been modified as well. Note that while there are API/ABI incompatible
4104 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
4105 its API/ABI have not changed. From this version on, GnuTLS requires
4106 OpenCDK 0.6.0 or later.
4108 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
4110 ** Change certtool's default serial number from 0 to a time-based value.
4112 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
4113 Before, we remove the parameters field, which resulted in a slightly
4114 different DER encoding which in turn caused signature verification
4115 failures of GnuTLS-generated RSA certificates in some other
4116 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
4117 you read, this may or may not be correct, but our new behaviour appear
4118 to be consistent with other widely used implementations.
4120 ** Fix mem leaks in gnutls_x509_crt_print.
4122 ** API and ABI modifications:
4123 No changes since last version.
4125 * Version 1.7.8 (released 2007-04-16)
4127 ** Added examples for the authorization extension.
4128 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
4130 ** The examples only use gnutls_set_default_priority().
4131 The exception is when DH_ANON is needed.
4133 ** Improve gnutls_set_default_priority() priorities.
4134 The new approach is for it to try and negotiate all secure and
4135 standard mechanisms available. Currently, DH_ANON ciphersuites and
4136 LZO compressions are not enabled by default, because they are,
4137 respectively, insecure and non-standardized. Note that TLS 1.2 will
4138 not be enabled by default in non-experimental release until it has
4139 been approved by the IETF.
4141 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
4142 This means that to get DH_ANON and LZO compression, you'll need to
4143 specify that manually using '--kx anon' or '--comp lzo'.
4145 ** Minor fixes to the human display format of X.509 certificates.
4147 ** New APIs to extract Distinguished Name's from X.509 certificates.
4148 Based on patch from Howard Chu <hyc@symas.com>.
4150 ** Improved library searching for opencdk.
4151 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
4152 The deprecated opencdk.m4 is no longer used.
4154 ** New APIs to list supported algorithms in the library.
4155 The APIs are gnutls_cipher_list, gnutls_mac_list,
4156 gnutls_compression_list, gnutls_protocol_list,
4157 gnutls_certificate_type_list, gnutls_kx_list, and
4158 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
4160 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
4162 ** New configure option --disable-tls-authorization to disable tls-authz.
4164 ** Fix prototype for `gnutls_psk_set_client_credentials'.
4165 The last parameter was renamed from 'flags' to 'format' and the type
4166 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
4167 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
4170 ** Fix allocation in gnutls_certificate_set_openpgp_key.
4171 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
4173 ** API and ABI modifications:
4174 gnutls_x509_dn_t: ADD.
4175 gnutls_x509_ava_st: ADD.
4176 gnutls_x509_crt_get_subject,
4177 gnutls_x509_crt_get_issuer: ADD.
4178 gnutls_x509_dn_get_rdn_ava: ADD.
4179 gnutls_cipher_list: ADD.
4180 gnutls_mac_list: ADD.
4181 gnutls_compression_list: ADD.
4182 gnutls_protocol_list: ADD.
4183 gnutls_certificate_type_list: ADD.
4184 gnutls_kx_list: ADD.
4185 gnutls_cipher_suite_info: ADD.
4187 * Version 1.7.7 (released 2007-02-22)
4189 ** Support for supplemental handshake messages and authorization data.
4190 Supplemental data is described in RFC 4680 and the authorization
4191 extensions in draft-housley-tls-authz-extns-07.
4193 ** Support for authorization data in gnutls-cli and gnutls-serv.
4194 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
4196 ** Fix for gnutls_x509_crt_check_hostname.
4197 Before it would have reported that the certificate matched a hostname
4198 when it did not have any dNSName or any CN field. Report and tiny
4199 patch from "Richard W.M. Jones" <rjones@redhat.com>.
4201 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
4202 Tests regressions of the bug, and several other features.
4204 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
4205 Before there were no support for iPAddress SAN's during comparison.
4207 ** New API to print information about CRL's.
4208 The function is gnutls_x509_crl_print.
4210 ** New API to extract signature value from CRL's.
4211 The function is gnutls_x509_crl_get_signature.
4213 ** Support for directoryName Subject Alternative Name's.
4214 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
4215 string in the provided buffer.
4217 ** Internal improvements to certtool.
4218 It uses gnutls_x509_crl_print to print CRL information. It uses some
4219 more gnulib modules to simplify error handling.
4221 ** API and ABI modifications:
4222 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
4223 gnutls_supplemental_data_format_type_t: ADD.
4224 gnutls_authz_data_format_type_t: ADD.
4225 gnutls_supplemental_get_name: ADD.
4226 gnutls_authz_recv_callback_func,
4227 gnutls_authz_send_callback_func: ADD, callback prototypes.
4228 gnutls_authz_enable: ADD.
4229 gnutls_authz_send_x509_attr_cert,
4230 gnutls_authz_send_saml_assertion,
4231 gnutls_authz_send_x509_attr_cert_url,
4232 gnutls_authz_send_saml_assertion_url: ADD.
4233 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
4234 gnutls_x509_crl_print: ADD.
4235 gnutls_x509_crl_get_signature: ADD.
4237 * Version 1.7.6 (released 2007-02-12)
4239 ** Support for 'otherName' Subject Alternative Names.
4240 The existing API gnutls_x509_crt_get_subject_alt_name may now return
4241 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
4242 To find out the otherName OID (necessary for proper parsing of the
4243 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
4244 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
4245 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
4246 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
4248 ** Certtool can print otherName SAN values for certificates.
4249 For known otherName OIDs (currently only id-on-xmppAddr as defined by
4250 RFC 3920), it will also print the name.
4252 ** Fix TLS 1.2 RSA signing in servers.
4253 Before it used the old-style MD5+SHA1 signature, but the TLS
4254 signatures should be normal PKCS#1 signatures. FYI, we use and
4255 require that DigestInfo parameters are present and NULL for TLS 1.2.
4257 ** Add APIs to access X.509 extensions sequentially.
4258 The existing APIs gnutls_x509_crt_get_extension_oid() and
4259 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
4260 inspect the extensions in the order defined by the certificate.
4262 ** Add API to extract signature value from X.509 certificates.
4263 The function is gnutls_x509_crt_get_signature.
4265 ** Fix crash when generating proxy certificates in batch mode.
4266 If you don't specify a proxy policy in batch mode, it will use
4269 ** Add API to print information about X.509 certificates.
4270 The function is gnutls_x509_crt_print.
4272 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
4273 One consequence of this is that the output syntax has changed
4274 slightly. Some more fields are printed.
4278 ** API and ABI modifications:
4279 gnutls_x509_crt_print: ADD
4280 gnutls_certificate_print_formats_t: ADD, new enum.
4281 gnutls_x509_crt_get_signature: ADD.
4282 gnutls_x509_crt_get_extension_data: ADD.
4283 gnutls_x509_crt_get_extension_info: ADD.
4284 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
4285 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
4286 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
4288 * Version 1.7.5 (released 2007-02-06)
4290 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
4293 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
4295 ** Fix --list output for gnutls-cli and gnutls-serv.
4296 Mention TLS1.2, SHA512 etc.
4298 ** Manual contains new section on setting up a test HTTP server.
4299 A server set up following those descriptions are available online via
4300 <http://www.gnutls.org/server.html>.
4302 ** Update of gnulib files.
4304 ** API and ABI modifications:
4305 No changes since last version.
4307 * Version 1.7.4 (released 2007-02-05)
4309 ** Support for RSA signing using SHA-256/384/512.
4310 A new self test "sha2" tries to build a long X.509 certificate chain
4311 testing all new hashes.
4313 ** The gnutls-serv tool now use static DH parameters if none are supplied.
4315 ** Discuss proxy certificates in the manual.
4317 ** Improve bibliographical citations in the manual.
4319 ** Update of gnulib files.
4321 ** Fix certtool template handling of pathLenConstraints.
4322 It now defaults to -1 instead of 0, which causes the field to be
4323 missing unless the template specify it.
4325 ** API and ABI modifications:
4328 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
4331 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
4332 GNUTLS_SIGN_RSA_SHA256,
4333 GNUTLS_SIGN_RSA_SHA384,
4334 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
4336 * Version 1.7.3 (released 2007-02-01)
4338 ** New option to certtool: --generate-proxy.
4339 This will generate a Proxy Certificate from an end entity certificate.
4340 Proxy Certificates are documented in RFC 3820. You will need to
4341 specify the proxy certificate's private key with --load-privkey, the
4342 user certificate with --load-certificate and the private key used to
4343 sign the new proxy certificate with --load-ca-privkey. Certtool will
4344 query for proxy path length and the policy language OID. Currently
4345 only OIDs that have an empty policy are supported (which includes the
4346 two OIDs defined by RFC 3820).
4348 ** Certtool --certificate-info now prints information for Proxy Certificates.
4349 Before the proxy extension was just printed as DER encoded data.
4351 ** New APIs to set proxy subject names and get/set proxy cert extension.
4353 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
4355 ** Added self-test to test for regressions of pathLenConstraint bug.
4356 Incidentally, this also test (some) other regressions or changes in
4357 the output from certtool --certificate-info.
4359 ** When certtool generates CA certificates, pressing enter on the path
4360 ** length constraint query will now remove the field.
4361 Before it set the path length constraint to 0, which is a rather poor
4364 ** Certtool now print times in UTC when printing certificate/CRL info.
4366 ** Add better fix to work around C++ compiler bug on Mac OS X.
4367 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
4369 ** Fix import of ASCII armored OpenPGP keys.
4370 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
4372 ** Update of gnulib files.
4374 ** API and ABI modifications:
4375 gnutls_x509_crt_set_proxy_dn: ADD.
4376 gnutls_x509_crt_set_proxy: ADD.
4377 gnutls_x509_crt_get_proxy: ADD.
4379 * Version 1.7.2 (released 2007-01-14)
4381 ** Certtool now print the value of the pathLenConstraints field for certs.
4383 ** Certtool now query for path length constraints when generating CA certs.
4384 For batch uses, the certtool configuration name is "path_len".
4385 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
4387 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
4388 The new functions gnutls_x509_crt_get_basic_constraints and
4389 gnutls_x509_crt_set_basic_constraints provide a superset of the
4390 functionality in the old gnutls_x509_crt_get_ca_status and
4391 gnutls_x509_crt_set_ca_status (respectively), but the old functions
4392 will continue to be supported.
4394 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
4395 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
4396 OpenCDK release with this patch will be made soon, which should bump
4397 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
4399 ** Certtool --to-p12 can now store more than one certificate in the blob.
4400 Before it could only store one certificate, but now it will read and
4401 store as many certificate there are from the --load-certificate file.
4402 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
4404 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
4405 In particular, the OpenPGP function variables are no longer part of
4406 the exported libgnutls interface, and no header files from
4407 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
4408 were never intended for non-internal purposes, and thus this does not
4409 imply a change in the external API/ABI.
4411 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
4412 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
4414 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
4415 Before these parameters were set to make GnuTLS build under mingw32,
4416 however, they appear to no longer be necessary.
4418 ** A minor fix to the C++ library to make it build.
4419 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
4421 ** Update of gnulib files.
4423 ** API and ABI modifications:
4424 gnutls_x509_crt_get_basic_constraints: ADD.
4425 gnutls_x509_crt_set_basic_constraints: ADD.
4426 cdk_pubkey_to_sexp: ADD (in opencdk).
4427 cdk_seckey_to_sexp: ADD (in opencdk).
4429 * Version 1.7.1 (released 2006-12-28)
4431 ** TLS 1.2 server side fix.
4432 The Certificate Request sent did not contain the list of supported
4433 hashes field, thus violating the protocol. It will now contain an
4434 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
4436 ** TLS 1.2 DSA signature verification fix.
4437 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
4439 ** Fix the list of trusted CAs that server's send to clients.
4440 Before, the list contained issuer DN's instead of subject DN's of the
4441 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
4443 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
4444 Also added a self-test in tests/certificate_set_x509_crl.c to test the
4445 function. Reported by Max Kellermann <max@duempel.org>.
4447 ** Encode UID fields in DN's as DirectoryString.
4448 Before GnuTLS encoded and parsed UID fields as IA5String. This was
4449 incorrect, it should have used DirectoryString. Now it will use
4450 DirectoryString for the UID field, but for backwards compatibility it
4451 will also accept IA5String UID's. Reported by Max Kellermann
4454 ** Improve out-of-sourcedir builds from CVS.
4455 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
4457 ** Bootstrap tools changed.
4458 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
4459 building GnuTLS from CVS. Libtool 1.5.22 is used.
4461 ** Fixed a syntax error in lib/gnutls.asn.
4462 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
4464 ** Added German translation of GnuTLS messages.
4466 ** Update of gnulib files.
4468 ** API and ABI modifications:
4469 No changes since last version.
4471 * Version 1.7.0 (released 2006-11-29)
4473 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
4474 The details is that the protocol priority set by
4475 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
4476 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
4478 ** Preliminary support for TLS 1.2.
4479 The client has been successfully tested against
4480 https://www.mikestoolbox.org:4433/.
4482 ** Anonself test now print a lot of debugging info, including TLS version.
4484 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
4486 ** Update of gnulib files.
4488 ** API and ABI modifications:
4489 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
4491 *** Pulled up from stable 1.6.x branch:
4493 ** Fix ./configure failure with non-GCC compilers.
4494 This fixes the following error message:
4495 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
4496 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
4498 * Version 1.6.3 (released 2007-05-26)
4500 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
4501 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
4502 from the 1.7.x branch, see
4503 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
4505 ** Have PKCS8 parser return better error codes.
4506 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
4507 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
4508 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
4510 ** Fix mem leak for sessions with client authentication via certificates.
4511 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
4512 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
4514 ** Fix building of 'tlsia' self test.
4515 Earlier some gcc are known to build tlsia linking to
4516 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
4517 the build directory, even though command line parameters look OK.
4518 Changing order of some parameters fixes it.
4520 ** API and ABI modifications:
4521 gnutls_x509_crt_get_raw_issuer_dn: ADD.
4522 gnutls_x509_crt_get_raw_dn: ADD.
4524 * Version 1.6.2 (released 2007-04-18)
4526 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
4527 Before, we remove the parameters field, which resulted in a slightly
4528 different DER encoding which in turn caused signature verification
4529 failures of GnuTLS-generated RSA certificates in some other
4530 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
4531 you read, this may or may not be correct, but our new behaviour appear
4532 to be consistent with other widely used implementations.
4534 ** Regenerate the PKIX ASN.1 syntax tree.
4535 For some reason, after changing the ASN.1 type of ldap-UID in the last
4536 release, the generated C file built from the ASN.1 schema was not
4537 refreshed. This can cause problems when reading/writing UID
4538 components inside X.500 Distinguished Names. Reported by devel
4539 <dev001@pas-world.com>.
4541 ** Updated translations.
4543 ** API and ABI modifications:
4544 No changes since last version.
4546 * Version 1.6.1 (released 2006-12-28)
4548 ** Fix the list of trusted CAs that server's send to clients.
4549 Before, the list contained issuer DN's instead of subject DN's of the
4550 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
4552 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
4553 Reported by Max Kellermann <max@duempel.org>.
4555 ** Encode UID fields in DN's as DirectoryString.
4556 Before GnuTLS encoded and parsed UID fields as IA5String. This was
4557 incorrect, it should have used DirectoryString. Now it will use
4558 DirectoryString for the UID field, but for backwards compatibility it
4559 will also accept IA5String UID's. Reported by Max Kellermann
4562 ** Fix ./configure failure with non-GCC compilers.
4563 This fixes the following error message:
4564 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
4565 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
4567 ** API and ABI modifications:
4568 No changes since last version.
4570 * Version 1.6.0 (released 2006-11-17)
4572 ** No changes since 1.5.5.
4573 The major changes compared to the 1.4.x branch are:
4575 *** A GnuTLS C++ library is part of the official distribution.
4576 Currently there are no examples or documentation, but hopefully this
4577 will change. See gnutlsxx.h for the API.
4579 *** Windows is a supported platform.
4580 There are, however, two know bugs. One is related to select() in
4581 command line tools (not, nota bene, in the library), the other is a
4582 problem with libgcrypt that causes delays. Help is needed to resolve
4583 those issues, so we feel we can't delay the release because of this.
4585 *** New APIs for custom push/pull function error reporting.
4586 The new APIs are gnutls_transport_set_errno and
4587 gnutls_transport_set_global_errno. See the release notes for version
4588 1.5.4 for more information.
4590 *** Self tests are run under valgrind, if available. See --disable-valgrind.
4592 * Version 1.5.5 (released 2006-11-16)
4594 ** Correctly bump shared library version after adding new APIs.
4595 This was forgotten in the last release.
4597 ** Fix unsigned vs signed problem in ex-x509-info.c example.
4598 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
4600 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
4602 ** Update of gnulib files.
4604 ** API and ABI modifications:
4605 No changes since last version.
4607 * Version 1.5.4 (released 2006-11-07)
4609 ** New API functions to set errno in push/pull functions.
4610 Under Windows, setting the errno variable in a push/pull replacement
4611 may end up setting the wrong errno variable, and GnuTLS send/recv
4612 functions become confused about the real errno returned from a failed
4613 push/pull function. Therefor, we have added two APIs to set the errno
4614 variable used by GnuTLS. The APIs can also help to keep things
4615 thread-safe, by avoiding potentially global variables. Typically,
4616 instead of setting errno in your push/pull function, you will call one
4617 of these functions. It is recommended to use
4618 gnutls_transport_set_errno, but if you don't have the session variable
4619 easily accessible in the push/pull replacement function, you can use
4620 gnutls_transport_set_global_errno. Suggested by Tim Kosse
4621 <tim.kosse@filezilla-project.org>.
4623 void gnutls_transport_set_errno (gnutls_session_t session, int err);
4624 void gnutls_transport_set_global_errno (int err);
4626 ** When calling `recv' or `send' Windows errors are handled properly.
4627 The Windows recv/send functions doesn't use errno, and GnuTLS now use
4628 WSAGetLastError to access the error condition instead.
4630 ** Several OpenPGP API fixes.
4631 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
4632 important fix is to change the return value of
4633 gnutls_openpgp_privkey_get_pk_algorithm and
4634 gnutls_openpgp_key_get_pk_algorithm from 'int' to
4635 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
4636 compatible with 'int').
4638 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
4639 ** version, try to negotiate the highest version support by the GnuTLS server,
4640 ** instead of the lowest.
4641 Reported by <Pasi.Eronen@nokia.com>.
4643 ** Replace old constructs with use of gnulib modules.
4644 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
4645 the code. If the headers doesn't exist on the target system, gnulib
4646 will make sure its replacement header files are used instead.
4648 ** Fix SOVERSION computation for *.def files.
4649 This fixes build errors similar to "No rule to make target
4650 `libgnutls-`expr', needed by `all-am'." when building for Windows.
4652 ** gnutls_check-version uses strverscmp from gnulib.
4654 ** Update of gnulib files.
4656 ** API and ABI modifications:
4657 gnutls_transport_set_errno: ADD
4658 gnutls_transport_set_global_errno: ADD
4660 * Version 1.5.3 (released 2006-10-26)
4662 ** Add new self-test of RSA-MD5 signature chains.
4663 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
4664 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
4665 and is based on the work by Marc Stevens et al, see
4666 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
4668 ** Re-factor self tests.
4670 ** The include copy of Libtasn1 is updated to version 0.3.7.
4672 ** The included copy of OpenCDK is updated to version 0.5.11.
4674 ** Fix the filename of the *.def file on Windows after library version bump.
4676 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
4677 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
4678 gnulib modules. Earlier we could only use the LGPL'ed module from
4679 gnulib, because two gnulib directories in the same project didn't
4682 ** API and ABI modifications:
4683 No changes since last version.
4685 * Version 1.5.2 (released 2006-10-03)
4687 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
4688 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
4689 shared library version than this version, so you'll have to remove
4690 them and possibly relink your applications. The reason for this is
4691 that no API/ABI changes have been made since the 1.4.x branch, and
4692 that incrementing the shared library version was a mistake. Reported
4693 by Andreas Metzler <ametzler@downhill.at.eu.org>.
4695 ** Fix off-by-one error when computing length to malloc.
4696 The code is used by gnutls_openpgp_add_keyring_file and
4697 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
4698 <agl@imperialviolet.org>.
4700 ** Add version script for the GnuTLS C++ library.
4701 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
4703 ** Fix the C++ compiler detection logic.
4704 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
4706 ** Update of gnulib files.
4708 ** API and ABI modifications:
4709 No changes since last version.
4711 * Version 1.5.1 (released 2006-09-21)
4713 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
4714 ** Crypto 06 rump session attack.
4715 In particular, we check that the digestAlgorithm.parameters field is
4716 missing or empty, to avoid that it can contain "garbage" that may be
4717 used to alter the numeric properties of the signature. See
4718 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
4719 not exactly the same as the problem we fix here). Reported by Yutaka
4720 OIWA <y.oiwa@aist.go.jp>.
4722 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
4723 up to date information.
4725 ** Add self test to test for above flaw.
4727 ** Fix gnutls-cli-debug regarding resume support detection.
4728 Earlier, if the session-id from the server had a length of 0, it would
4729 indicate that the server supports resumption, which isn't the case.
4730 Reported by Kataja Kai <kai.kataja@op.fi>.
4732 ** Fix building of examples on FreeBSD by including netinet/in.h.
4733 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
4735 ** Fix certtool bug that caused the private key to not be loaded when
4736 generating a certificate with --load-request, which in turn triggered
4737 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
4738 by Sascha Ziemann <sascha.ziemann@secunet.com>.
4740 ** gnutls-cli and gnutls-serv works on Windows.
4741 The problem was the select() call that doesn't work on file
4742 descriptors (stdin) on Windows. We borrowed some code from plibc to
4743 solve this. It appears to be somewhat unreliable though.
4745 ** Autoconf 2.60 is now used.
4747 ** API and ABI modifications:
4748 No changes since last version.
4750 * Version 1.5.0 (released 2006-08-13)
4752 ** Change SRP and Cert-Type extensions to match IANA registry.
4754 ** Fixed bug in OpenPGP authentication handshake.
4756 ** Improvements for building under MinGW.
4757 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
4758 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
4759 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
4760 at run-time from ws2_32.dll, and falls back on a simple replacement if
4761 it is not available. Builds the library with -mms-bitfields
4762 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
4763 create *.def files, which are installed.
4765 ** The examples now (conditionally) include config.h and link to gnulib.
4766 No other source changes were necessary, so the examples should
4767 continue to be possible to use stand-alone without any autoconf or
4770 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
4771 You may unconditionally disable it with --disable-cxx. See
4772 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
4775 ** Made command line tool '--version' behave according to GNU Standards.
4776 This enables 'make distcheck' to succeed.
4778 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
4780 ** Make --without-included-libtasn1 work.
4781 Reported by Daniel Black <dragonheart@gentoo.org>.

4806 ** Relax the test that caught signatures that exploit the variant of
4807 ** Bleichenbacher's Crypto 06 rump session attack on our
4808 ** verification logic flaw.
4809 In particular, we now permit the digestAlgorithm.parameters field to
4810 be present but empty, whereas in 1.4.3 we actually checked that the
4813 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
4814 The messages are only printed in debug mode, which is not recommended
4815 for normal use, and thus logging this situation cannot be abused as an
4816 oracle in typical recommended situations.
4818 ** API and ABI modifications:

4825 In particular, we check that the digestAlgorithm.parameters field is
4826 empty, to avoid that it can contain "garbage" that may be used to

4847 * Version 1.4.2 (released 2006-08-12)
4849 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
4850 This can happen if you call gnutls_certificate_verify_peers2 and have
4851 a certain mix of local CA certificates and the peer send special
4852 certificates, that together trigger certain behaviour. It is not
4853 known at this point whether the crash can be triggered without the
4854 special local CA certificate, and thus turn this into a remote crash
4855 of clients that verify server certificates when they talk to a server
4856 with the special server certificate. See GNUTLS-SA-2006-2 on
4857 http://www.gnu.org/software/gnutls/security.html for more up to date
4858 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
4860 ** Change SRP and Cert-Type extensions to match IANA registry.
4862 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
4864 ** Make --without-included-libtasn1 work.
4865 Reported by Daniel Black <dragonheart@gentoo.org>.
4867 ** API and ABI modifications:
4868 No changes since last version.
4870 * Version 1.4.1 (released 2006-06-14)
4872 ** Replaced inactive ifdefs to enable openpgp support in test programs.
4874 ** Fixed bug in OpenPGP authentication handshake.
4876 ** Fixed typographical in man pages.
4878 ** Build fixes of the manual.

4887 ** Remove GnuTLS 0.8.x compatibility functions.
4889 ** The libgcrypt RNG is initialized in gnutls_global_init().
4891 ** TLS/IA API changes from Emile van Bergen.
4892 A dummy credential structure is not needed now, if you wish to use the
4893 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
4896 ** The self-tests are now run under valgrind, if it is installed.
4898 ** Libtasn1 is updated to 0.3.4, and that version is now required.
4900 ** The command line tools now use getaddrinfo and support IPv6.
4902 ** API and ABI modifications:
4903 _gnutls_x509_get_raw_crt_activation_time,
4904 _gnutls_x509_get_raw_crt_expiration_time: Removed.
4905 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
4906 gnutls_ia_enable: Added.
4908 * Version 1.3.5 (released 2006-03-08)
4910 ** Error messages are now translated using GNU Gettext.
4912 ** The function gnutls_x509_crt_to_xml now return an internal error.
4913 This means that the code to convert X.509 certificates to XML format
4914 does not work any more. The reason is that the function called
4915 libtasn1 internal functions. It seems unclean for libtasn1 to export
4916 the APIs needed here. Instead it would be better to implement XML
4917 support inside libtasn1 properly. If you need this functionality
4918 strongly, please consider looking into implementing this suggested
4919 approach instead. As a workaround, you may also modify lib/x509/xml.c
4920 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
4922 ** Libraries are now built with libtool's -no-undefined.
4923 This helps producing libraries for Windows using mingw32.
4925 ** Doc fixes to explain that gnutls_record_send can block.
4927 ** Libtasn1 0.3.1 or later is now required.
4928 The include copy has been updated too.
4930 ** gnutls-cli can now recognize services and port numbers with the -p option.
4932 ** API and ABI modifications:
4933 No changes since last version.
4935 * Version 1.3.4 (released 2006-02-09)
4937 ** Fix read of out bounds bug in DER parser.
4938 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
4939 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
4940 previous bug fix. The included libtasn1 version in GnuTLS has been
4943 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
4944 longer invalidate a session if the underlying send fails, but it will
4945 prevent future writes. That is to allow reading the already received data.
4946 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
4948 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
4949 gnutls_certificate_set_x509_trust(), that caused memory corruption if
4950 more than one certificates were added. Report and patch by Max Kellermann.
4952 ** Fix build problems of OpenCDK on AIX.
4953 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
4955 ** API and ABI modifications:
4956 No changes since last version.
4958 * Version 1.3.3 (released 2006-01-12)
4960 ** New API to access the TLS master secret.
4961 When possible, you should use the TLS PRF functions instead.
4962 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
4964 ** Improved handling when multiple libraries use GnuTLS at the same time.
4965 Now gnutls_global_init() can be called multiple times, and
4966 gnutls_global_deinit() will only deallocate the structure when it has
4967 been called as many times as gnutls_global_init() was called.
4969 ** Added a self test of TLS resume functionality.
4971 ** Fix crash in TLS resume code, caused by TLS/IA changes.
4973 ** Documentation fixes about thread unsafety, prompted by
4974 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
4975 In particular, gnutls_global_init() and gnutls_global_deinit() are not
4976 thread safe. Careful callers may want to protect the call using a
4977 mutex. The problem could also be ignored, which would cause a memory
4978 leak under rare conditions when two threads invoke the function
4979 roughly at the same time.
4981 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
4983 ** The code was indented again, including the external header files.
4985 ** API and ABI modifications:
4986 New functions to retrieve the master secret value:
4987 gnutls_session_get_master_secret
4989 Add a 'const' keyword to existing API:
4990 gnutls_x509_crq_get_challenge_password
4992 * Version 1.3.2 (released 2005-12-15)
4994 ** GnuTLS now support TLS Inner application (TLS/IA).
4995 This is per draft-funk-tls-inner-application-extension-01. This
4996 functionality is added to libgnutls-extra, so it is licensed under the
4997 GNU General Public License.
4999 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
5000 The PRF is used by some protocols building on TLS, such as EAP-PEAP
5001 and EAP-TTLS. One function to access the raw PRF and one to access
5002 the PRF seeded with the client/server random fields are provided.
5003 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5005 ** New APIs to acceess the client and server random fields in a session.
5006 These fields can be useful by protocols using TLS. Note that these
5007 fields are typically used as input to the TLS PRF, and if this is your
5008 intended use, you should use the TLS PRF API that use the
5009 client/server random field directly. Suggested by Jouni Malinen
5010 <jkmaline@cc.hut.fi>.
5012 ** Internal type cleanups.
5013 The uint8, uint16, uint32 types have been replaced by uint8_t,
5014 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
5015 correct types on platforms that lack them. The uint type have been
5016 replaced by unsigned.
5018 ** API and ABI modifications:
5019 New functions to invoke the TLS Pseudo-Random-Function (PRF):
5023 New functions to retrieve the session's client and server random values:
5024 gnutls_session_get_server_random
5025 gnutls_session_get_client_random
5027 New function, to perform TLS/IA handshake:
5030 New function to decide whether to do a TLS/IA handshake:
5031 gnutls_ia_handshake_p
5033 New functions to allocate a TLS/IA credential:
5034 gnutls_ia_allocate_client_credentials
5035 gnutls_ia_free_client_credentials
5036 gnutls_ia_allocate_server_credentials
5037 gnutls_ia_free_server_credentials
5039 New functions to handle the AVP callback:
5040 gnutls_ia_set_client_avp_function
5041 gnutls_ia_set_client_avp_ptr
5042 gnutls_ia_get_client_avp_ptr
5043 gnutls_ia_set_server_avp_function
5044 gnutls_ia_set_server_avp_ptr
5045 gnutls_ia_get_server_avp_ptr
5047 New functions, to toggle TLS/IA application phases:
5048 gnutls_ia_require_inner_phase
5050 New function to mix session keys with inner secret:
5051 gnutls_ia_permute_inner_secret
5053 Low-level API (used internally by gnutls_ia_handshake):
5054 gnutls_ia_endphase_send
5058 New functions that can be used after successful TLS/IA negotiation:
5059 gnutls_ia_generate_challenge
5060 gnutls_ia_extract_inner_secret
5062 Enum type with TLS/IA modes:
5065 Enum type with TLS/IA packet types:
5068 Enum values for TLS/IA alerts:
5069 GNUTLS_A_INNER_APPLICATION_FAILURE
5070 GNUTLS_A_INNER_APPLICATION_VERIFICATION
5072 New error codes, to signal when an application phase has finished:
5073 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
5074 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
5076 New error code to signal TLS/IA verify failure:
5077 GNUTLS_E_IA_VERIFY_FAILED
5079 * Version 1.3.1 (released 2005-12-08)
5081 ** Support for DHE-PSK cipher suites has been added.
5082 This method offers perfect forward secrecy.
5084 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5085 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5087 ** Corrected a bug in certtool for 64 bit machines. Reported
5088 by Max Kellermann <max@duempel.org>.
5090 ** New function to set a X.509 private key and certificate pairs, and/or
5091 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
5092 <emile@e-advies.nl>.
5094 The integrity of the PKCS#12 file is protected through a password
5095 based MAC; public-key based signatures for integrity protection are
5096 not supported. PKCS#12 bags may be encrypted using password derived
5097 symmetric keys, public-key based encryption is not supported. The
5098 PKCS#8 keys may be encrypted using passwords. The API use the same
5099 password for all operations. We believe that any more flexibility
5100 create too much complexity that would hurt overall security, but may
5101 add more PKCS#12 related APIs if real-world experience indicate
5104 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
5105 reported by Emile van Bergen <emile@e-advies.nl>.
5106 This will enable "certtool -k -8" to parse those keys.
5108 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
5109 Use "certtool -p -8" and press press enter at the prompt. Earlier,
5110 certtool would have encrypted the key using an empty password.
5112 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.

5200 * Version 1.2.11 (2006-05-11)
5201 - The function gnutls_x509_crt_to_xml is not supported any more, and
5202 return an internal error. The reason is that the function called
5203 internal libtasn1 functions which are no longer exported from
5205 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
5206 - Updated gnulib compatibility files.
5207 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
5208 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
5209 - API and ABI modifications:
5210 No changes since last version.
5212 * Version 1.2.10 (2006-02-09)
5213 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
5214 <admin@gleg.net>, and debugging help from Protover SSL.
5215 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
5216 The included version has been updated too.
5217 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5218 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5219 - Corrected a bug in certtool for 64 bit machines. Reported
5220 by Max Kellermann <max@duempel.org>.
5221 - Corrected bugs in gnutls_certificate_set_x509_crl() and
5222 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5223 more than one certificates were added. Report and patch by Max Kellermann.
5224 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5225 longer invalidate a session if the underlying send fails, but it will
5226 prevent future writes. That is to allow reading the already received data.
5227 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5229 * Version 1.2.9 (2005-11-07)
5230 - Documentation was updated and improved.
5231 - RSA-MD2 is now supported for verifying digital signatures.
5232 - Due to cryptographic advances, verifying untrusted X.509
5233 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
5234 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
5235 applications that must remain interoperable, you can use the
5236 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
5237 flags when verifying certificates. Naturally, this is not
5238 recommended default behaviour for applications. To enable the
5239 broken algorithms, call gnutls_certificate_set_verify_flags with the
5240 proper flag, to change the verification mode used by
5241 gnutls_certificate_verify_peers2.
5242 - Make it possible to send empty data through gnutls_record_send,
5243 to align with the send(2) API.
5244 - Some changes in the certificate receiving part of handshake to prevent
5245 some possible errors with non-blocking servers.
5246 - Added numeric version symbols to permit simple CPP-based feature
5247 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
5248 - The (experimental) low-level crypto alternative to libgcrypt used
5249 earlier (Nettle) has been replaced with crypto code from gnulib.
5250 This leads to easier re-use of these components in other projects,
5251 leading to more review and simpler maintenance. The new configure
5252 parameter --with-builtin-crypto replace the old --with-nettle, and
5253 must be used if you wish to enable this functionality. See README
5254 under "Experimental" for more information. Internally, GnuTLS has
5255 been updated to use the new "Generic Crypto" API in gl/gc.h. The
5256 API is similar to the old crypto/gc.h, because the gnulib code were
5257 based on GnuTLS's gc.h.
5258 - Fix compiler warning in the "anonself" self test.
5259 - API and ABI modifications:
5260 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
5261 This doesn't reflect a change in behaviour,
5262 so we don't break backwards compatibility.
5263 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
5264 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
5265 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
5266 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
5268 gnutls_x509_crt_list_verify,
5269 gnutls_x509_crt_verify, or
5270 gnutls_certificate_set_verify_flags.
5271 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
5272 used when broken signature algorithms
5273 is used (currently RSA-MD2/MD5).
5274 LIBGNUTLS_VERSION_MAJOR,
5275 LIBGNUTLS_VERSION_MINOR,
5276 LIBGNUTLS_VERSION_PATCH,
5277 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
5278 version number, can be used for feature existence
5281 * Version 1.2.8 (2005-10-07)
5282 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
5283 - Don't install the auxilliary libexamples library used by the
5284 examples in doc/examples/ on "make install", report and tiny patch
5285 from Thomas Klausner <tk@giga.or.at>.
5286 - If you pass a X.509 CA or PGP trust database to the command line
5287 tool, it will now abort the connection if the server certificate
5288 validation fails. Use the parameter --insecure to continue even
5289 after certificate validation failures. Inspired from discussion
5290 with Alexander Kotelnikov <sacha@myxomop.com>.
5291 - The test for socklen_t has been moved to gnulib.

5353 - Introduced the --fix-key option to certtool, which can be used to
5354 regenerate the (optional) parameters in a private key. It should
5355 be used together with --key-info.

5378 and made source code include external include file, to check
5379 function prototypes during compile time.
5380 - API and ABI modifications:
5381 No changes since last version. At least not intentional, but due
5382 to the include header changes, there may be inadvertant changes,
5383 please let us know if you find any.

5390 - Added warning to certtool when MD5 is being used for digital
5392 - Optimizations ("-O2 -finline-functions") are not enabled by default,
5393 instead the standard autoconf defaults are used. Use `./configure
5394 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
5395 - Added the option --get-dh-params to certtool, in order to get the
5396 parameters included in the library primes and generators.

5432 gnutls_x509_rdn_get now set *sizeof_buf to the buffer length that is
5433 required, instead of the string length. That is, the value has been
5434 incremented by 1 to account for the terminating zero. Reported by
5435 Martin Lambers <marlam@web.de>.
5436 - Debug output shouldn't crash on platforms that doesn't handle NULL
