160 and only try to verify the correct part. Patch by David Woodhouse
162 ** libgnutls: Restored the behavior of gnutls_x509_privkey_import_pkcs8()
163 which now may (again) accept a NULL password.

180 GNUTLS_E_LARGE_PACKET instead of being truncated.
182 ** libgnutls: gnutls_dtls_get_data_mtu() is more precise. Based
183 on patch by David Woodhouse.
185 ** libgnutls: Fixed memory leak in PKCS #8 key import.
187 ** libgnutls: Added support for an old version of the DTLS protocol
188 used by openconnect vpn client for compatibility with Cisco's AnyConnect
189 SSL VPN. It is marked as GNUTLS_DTLS0_9. Do not use it for newer protocols
192 ** libgnutls: Corrected bug that prevented resolving PKCS #11 URLs
193 if only the label is specified. Patch by David Woodhouse.

233 ** libgnutls: When decoding a PKCS #11 URL the pin-source field
234 is assumed to be a file that stores the pin. Based on patch
237 ** libgnutls: gnutls_record_check_pending() no longer
238 returns unprocessed data, and thus ensure the non-blocking
239 of the next call to gnutls_record_recv().
241 ** libgnutls: Added strict tests in Diffie-Hellman and
242 SRP key exchange public keys.
244 ** libgnutls: in ECDSA and DSA TLS 1.2 authentication be less

430 There is a new header file gnutls/ocsp.h and a set of new functions
431 under the gnutls_ocsp namespace. Currently the functionality provided
432 is to parse and extract information from OCSP requests/responses, to
433 generate OCSP requests and to verify OCSP responses. See the manual
434 for more information. Run ./configure with --disable-ocsp to build
435 GnuTLS without OCSP support.
437 This work was sponsored by Smoothwall <http://smoothwall.net/>.

515 in Linux as well as in BSD.
517 ** gnutls-cli: Fixed reading from windows terminals.
519 ** libgnutls: When GNUTLS_OPENPGP_FMT_BASE64 is specified
520 the stream is assumed to be base64 encoded (previously
521 the encoding was auto-detected). This avoids a decoding
522 issue in windows systems.
524 ** libgnutls: Corrected ciphersuite GNUTLS_ECDHE_PSK_AES_256_CBC_SHA384
526 ** libgnutls: Added ciphersuites: GNUTLS_PSK_WITH_AES_256_GCM_SHA384

544 it will only list the ciphersuites that are enabled by the given
547 ** libgnutls: Added new priority string %SERVER_PRECEDENCE, which
548 changes the ciphersuite selection procedure. If specified the server
549 priorities will be used for selection instead of the client's.
551 ** libgnutls: Optimizations in Diffie-Hellman parameters generation
554 ** libgnutls: When session tickets are negotiated and used in a
555 session, a server will not store that session data into its cache.

559 ** libgnutls: Added gnutls_priority_get_cipher_suite_index() to
560 allow listing the ciphersuites enabled in a priority structure.
561 It outputs an index to be used in gnutls_get_cipher_suite_info().
563 ** libgnutls: Optimizations in the elliptic curve code --timing
564 attacks resistant code is only used in ECDSA private key operations.
566 ** doc: man pages for API functions generation was fixed and are
567 now added again in the distribution.

583 ** libgnutls: Provide less timing information when decoding
584 TLS/DTLS record packets.
586 ** doc: man pages for API functions were removed.
587 The reason was that the code that auto-generated the man pages missed
588 many APIs and we couldn't fix it (volunteers welcome). See the info
589 manual or the GTK-DOC manual instead.

1224 * Version 2.11.6 (released 2010-12-06)
1226 ** libgnutls: Record version of Client Hellos is now set by default to
1227 SSL 3.0. To restore the previous default behavior use %LATEST_RECORD_VERSION
1230 ** libgnutls: Use ASN1_NULL when writing parameters for RSA signatures.
1231 This makes us comply with RFC3279. Reported by Michael Rommel.
1233 ** gnutls-serv: Corrected a buffer overflow. Reported and patch by Tomas Mraz.
1235 ** API and ABI modifications:
1236 No changes since last version.
1238 * Version 2.11.5 (released 2010-12-01)
1240 ** libgnutls: Reverted default behavior for verification and
1241 introduced GNUTLS_VERIFY_DO_NOT_ALLOW_X509_V1_CA_CRT. Thus by default
1242 V1 trusted CAs are allowed, unless the new flag is specified.
1244 ** libgnutls: Correctly add leading zero to PKCS #8 encoded DSA key.
1245 Reported by Jeffrey Walton.
1247 ** libgnutls: Added SIGN-ALL, CTYPE-ALL, COMP-ALL, and VERS-TLS-ALL
1248 as priority strings. Those allow to set all the supported algorithms
1251 ** p11tool: Introduced. It allows manipulating pkcs 11 tokens.
1253 ** gnutls-cli: Print channel binding only in verbose mode.
1254 Before it printed it after the 'Compression:' output, thus breaking
1255 Emacs starttls.el string searches.
1257 ** API and ABI modifications:
1258 gnutls_pkcs11_token_init: New function
1259 gnutls_pkcs11_token_set_pin: New function
1261 * Version 2.11.4 (released 2010-10-15)
1263 ** libgnutls: Add new API gnutls_session_channel_binding.
1264 The function is used to get the channel binding data. Currently only
1265 the "tls-unique" (RFC 5929) channel binding type is supported, through
1266 the GNUTLS_CB_TLS_UNIQUE type. See new section "Channel Bindings" in
1269 ** gnutls-cli, gnutls-serv: Print 'tls-unique' Channel Bindings.
1271 ** doc: Added pkcs11.h header file to GTK-DOC manual.
1273 ** build: Update gnulib files.
1275 ** i18n: Update translations.
1277 ** tests: Add self tests gendh.c. Speed up Guile self checks.
1279 ** API and ABI modifications:
1280 gnutls_session_channel_binding: New function.
1281 gnutls_channel_binding_t: New enumeration.
1282 GNUTLS_CB_TLS_UNIQUE: New gnutls_channel_binding_t enum member.
1283 GNUTLS_E_CHANNEL_BINDING_NOT_AVAILABLE: New error code.
1285 * Version 2.11.3 (released 2010-10-14)
1287 ** Indent code to follow the GNU Coding Standard.
1288 You should be able to unpack the 2.11.2 release and run 'make indent'
1289 twice to get exactly the same content as 2.11.3 except for generated
1290 files. Using GNU Indent 2.2.11.
1292 ** API and ABI modifications:
1293 No changes since last version.
1295 * Version 2.11.2 (released 2010-10-08)
1297 ** libgnutls: Several bug fixes on session resumption
1298 and session tickets support.
1300 ** libgnutls: Add new extended key usage ipsecIKE.
1302 ** certtool: Renamed PKCS #11 options to: --p11-provider,
1303 --p11-export-url, --p11-list-certs, --p11-list-certs,
1304 --p11-list-privkeys, --p11-list-trusted, --p11-list-all-certs,
1305 --p11-list-all, --p11-list-tokens, --p11-login, --p11-write,
1306 --p11-write-label, --p11-write-trusted, --p11-detailed-url,
1309 ** libgnutls: Corrected bug that caused importing DSA keys as RSA,
1310 introduced with the new nettle code.
1312 ** libgnutls: Corrected advertizing issue for session tickets.
1314 ** API and ABI modifications:
1315 gnutls_x509_crt_get_subject_unique_id: ADDED.
1316 gnutls_x509_crt_get_issuer_unique_id: ADDED.
1318 * Version 2.11.1 (released 2010-09-14)
1320 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
1321 to use the libgcrypt back end.
1323 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
1324 backend crypto library.
1326 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
1328 ** libgnutls: Several updates in the buffering internal interface.
1330 ** libgnutls: Is now more liberal in the PEM decoding. That is spaces and
1331 tabs are being skipped.
1333 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
1335 ** libgnutls: The %COMPAT flag now allows larger records that violate the
1338 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
1339 system calls. Applications that depended on it being 1 should explicitly call
1340 gnutls_transport_set_lowat().
1342 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
1343 to ECRYPT II recommendations. Mappings were moved to a single location
1344 and DSA keys are handled differently (since DSA2 allows for 1024,2048
1345 and 3072 keys only).
1347 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1348 gnutls_x509_privkey_import_pkcs8() without a password, if it
1349 is unable to decode the key.
1351 ** libgnutls: HMAC-MD5 no longer used by default.
1353 ** API and ABI modifications:
1354 gnutls_openpgp_privkey_sec_param: ADDED
1355 gnutls_x509_privkey_sec_param: ADDED
1357 * Version 2.11.0 (released 2010-07-22)
1359 ** libgnutls: support scattered write using writev(). This takes
1360 advantage of the new buffering layer and allows queuing of packets
1361 and flushing them. This is currently used for handshake messages
1364 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
1365 alternative locking procedures. By default the system available
1366 locking is used. In *NIX pthreads are used and in windows the
1367 critical section API. This follows a different approach than the
1368 previous versions that depended on libgcrypt initialization. The
1369 locks are now set by default in systems that support it. Programs
1370 that used gcry_control() to set thread locks should insert it into
1372 #if GNUTLS_VERSION_NUMBER <= 0x020b00
1376 ** libgnutls: Added support for reading DN from EV-certificates.
1378 jurisdictionOfIncorporationLocalityName,
1379 jurisdictionOfIncorporationStateOrProvinceName,
1380 jurisdictionOfIncorporationCountryName
1382 ** libgnutls: Added support for DSA signing/verifying with bit
1385 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
1386 has to be called to register any required md5 handlers.
1388 ** libgnutls: Internal buffering code was replaced by simpler
1389 code contributed by Jonathan Bastien-Filiatrault.
1391 ** libgnutls: Internal API for extensions augmented to allow
1392 safe storing and loading of data on resumption. This allows writing
1393 self-contained extensions (when possible). As a side effect
1394 the OPRFI extension was removed.
1396 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
1398 ** libgnutls: Added PKCS #11 support and an API to access objects in
1399 gnutls/pkcs11.h. Currently certificates and public keys can be
1400 imported from tokens, and operations can be performed on private keys.
1402 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
1404 ** libgnutls: Added initial support for the nettle library. It uses
1405 the system's random generator for seeding. That is /dev/urandom in Linux,
1406 system calls in Win32 and EGD on other systems.
1408 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
1409 works even when resuming a session.
1411 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
1412 similar gnutls_certificate_set_server_retrieve_function() and
1413 gnutls_certificate_set_client_retrieve_function(). In addition it support
1414 PKCS #11 private keys.
1416 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
1417 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
1419 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
1420 sizes for private keys using a human understandable scale.
1422 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
1423 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
1424 --pkcs11-delete-url, --pkcs11-write
1426 certtool: The --pkcs-cipher is taken into account when generating a
1427 private key. The default cipher used now is aes-128. The old behavior can
1428 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1430 certtool: Added --certificate-pubkey to print the public key of the
1433 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
1434 can now accept a PKCS #11 URL in addition to a file. This will allow for
1435 example to use the Gnome-keyring trusted certificate list to verify
1436 connections using a url such as:
1437 pkcs11:token=Root%20CA%20Certificates;serial=1%3AROOTS%3ADEFAULT;model=1%2E0;manufacturer=Gnome%20Keyring

1518 * Version 2.10.1 (released 2010-07-25)
1520 ** libgnutls: Added support for broken certificates that indicate RSA
1523 ** gnutls-cli: Allow verification using V1 CAs.
1525 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1526 gnutls_x509_privkey_import_pkcs8() without a password, if it
1527 is unable to decode the key.
1529 ** libgnutls: Correctly deinitialize crypto API functions to prevent
1530 a memory leak. Reported by Mads Kiilerich.
1532 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
1533 issue a warning, that the output key might not be working everywhere.
1535 ** certtool: The --pkcs-cipher is taken into account when generating a
1536 private key. The default cipher used now is aes-128. The old behavior
1537 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1539 ** API and ABI modifications:
1540 No changes since last version.
1542 * Version 2.10.0 (released 2010-06-25)
1544 ** API and ABI modifications:
1545 No changes since last version.
1547 * Version 2.9.12 (released 2010-06-17)
1549 ** gnutls-cli: Make --starttls work again.
1550 Problem introduced in patch to use read() instead of fgets() committed
1553 ** API and ABI modifications:
1554 No changes since last version.
1556 * Version 2.9.11 (released 2010-06-07)
1558 ** libgnutls: Removed two APIs related to safe renegotiation.
1559 Use priority strings instead. The APIs were
1560 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
1561 (Remember that we don't promise ABI stability during development
1562 series, so this doesn't cause an shared library ABI increment.)
1564 ** tests: More self testing of safe renegotiation extension.
1565 See tests/safe-renegotiation/README for more information.
1567 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
1569 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
1571 ** API and ABI modifications:
1572 gnutls_safe_negotiation_set_initial: REMOVED.
1573 gnutls_safe_renegotiation_set: REMOVED.
1575 * Version 2.9.10 (released 2010-04-22)
1577 ** libgnutls: Time verification extended to trusted certificate list.
1578 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
1581 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
1582 Based on patch by Pavan Konjarla. Adds new constant
1583 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
1585 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
1586 Solves the issue discussed in:
1587 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
1588 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
1589 Note that to allow connecting to unpatched servers the full protection
1590 is only enabled if the priority string %SAFE_RENEGOTIATION is
1591 specified. You can check whether protection is in place by querying
1592 gnutls_safe_renegotiation_status(). New error codes
1593 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
1594 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
1596 ** libgnutls: When checking openpgp self signature also check the signatures
1598 Ilari Liusvaara noticed and reported the issue and provided test
1601 ** libgnutls: Added cryptodev support (/dev/crypto).
1602 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
1603 benchmark utility for AES. Adds new error codes
1604 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
1606 ** libgnutls: Exported API to access encryption and hash algorithms.
1607 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
1608 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
1609 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
1610 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
1611 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
1612 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
1613 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
1615 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
1616 verification of certificate upon receipt rather than waiting until the
1617 end of the handshake.
1619 ** libgnutls: Don't send alerts during handshake.
1620 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
1622 ** certtool: Corrected two issues that affected certificate request generation.
1623 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
1624 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
1625 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
1626 those parameters there since other implementations don't do either and having
1627 them does not seem to offer anything (anyway you need the signer's certificate
1628 to verify thus public key will be available). Found thanks to Boyan Kasarov.
1629 This however has the side-effect that public key IDs shown by certtool are
1630 now different than previous gnutls releases.
1631 (3) the option --pgp-certificate-info will verify self signatures
1633 ** certtool: Allow exporting of Certificate requests on DER format.
1635 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
1637 ** gnutls-cli: Handle reading binary data from server.
1638 Reported by and tiny patch from Vitaly Mayatskikh
1639 <v.mayatskih@gmail.com> in
1640 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/4096>.
1642 ** minitasn1: Upgraded to libtasn1 version 2.6.
1644 ** i18n: Updated Czech, Dutch, French, Polish, Swedish translation.

1705 Reported by Tang Tong.
1707 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
1708 ** extension and certificate verify field.
1709 This requires changes for TLS 1.2 servers and clients that use
1710 callbacks for certificate retrieval. They are now required to check
1711 with gnutls_sign_algorithm_get_requested() whether the certificate
1712 they send complies with the peer's preferences in signature
1715 ** libgnutls: In server side when resuming a session do not overwrite the
1716 ** initial session data with the resumed session data.
1718 ** libgnutls: Added support for AES-128, AES-192 and AES-256 in PKCS #8
1720 This affects also PKCS #12 encoded files. This adds the following new
1721 enums: GNUTLS_CIPHER_AES_192_CBC, GNUTLS_PKCS_USE_PBES2_AES_128,
1722 GNUTLS_PKCS_USE_PBES2_AES_192, GNUTLS_PKCS_USE_PBES2_AES_256.
1724 ** libgnutls: Fix PKCS#12 encoding.

1772 * Version 2.9.5 (released 2009-09-10)
1774 ** libgnutls: Add new functions to extract X.509 Issuer Alternative Names.
1775 The new functions are gnutls_x509_crt_get_issuer_alt_name2,
1776 gnutls_x509_crt_get_issuer_alt_name, and
1777 gnutls_x509_crt_get_issuer_alt_othername_oid. Contributed by Brad

1788 The new supported ciphersuites are AES-128/256 in CBC mode with
1789 ANON-DH/RSA/DHE-DSS/DHE-RSA. Contributed by Daiki Ueno. Further,
1790 SHA-256 is now the preferred default MAC (however it is only used with
1793 ** libgnutls: Make OpenPGP hostname checking work again.
1794 The patch to resolve the X.509 CN/SAN issue accidentally broken
1795 OpenPGP hostname comparison.
1797 ** libgnutls: When printing X.509 certificates, handle XMPP SANs better.
1798 Reported by Howard Chu <hyc@symas.com> in
1799 <https://savannah.gnu.org/support/?106975>.
1801 ** Fix use of deprecated types internally.
1802 Use of deprecated types in GnuTLS from now on will lead to a compile
1803 error, to prevent this from happening again.
1805 ** API and ABI modifications:
1806 No changes since last version.
1808 * Version 2.9.3 (released 2009-08-19)
1810 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
1811 The new APIs are gnutls_session_ticket_enable_client,
1812 gnutls_session_ticket_enable_server, and
1813 gnutls_session_ticket_key_generate.
1815 ** gnutls-cli, gnutls-serv: New parameter --noticket to disable TLS tickets.

1822 * Version 2.9.2 (released 2009-08-14)
1824 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
1825 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
1826 into 1) not printing the entire CN/SAN field value when printing a
1827 certificate and 2) cause incorrect positive matches when matching a
1828 hostname against a certificate. Some CAs apparently have poor
1829 checking of CN/SAN values and issue these (arguable invalid)
1830 certificates. Combined, this can be used by attackers to become a
1831 MITM on server-authenticated TLS sessions. The problem is mitigated
1832 since attackers needs to get one certificate per site they want to
1833 attack, and the attacker reveals his tracks by applying for a
1834 certificate at the CA. It does not apply to client authenticated TLS
1835 sessions. Research presented independently by Dan Kaminsky and Moxie
1836 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
1837 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
1839 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
1840 The function may fail incorrectly when an earlier certificate was
1841 imported to the same gnutls_x509_crt_t structure.
1843 ** minitasn1: Internal copy updated to libtasn1 v2.3.
1845 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
1846 Before it always returned false. Reported by Peter Hendrickson
1847 <pdh@wiredyne.com> in
1848 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3668>.
1850 ** libgnutls: Fix off-by-one size computation error in unknown DN printing.
1851 The error resulted in truncated strings when printing unknown OIDs in
1852 X.509 certificate DNs. Reported by Tim Kosse
1853 <tim.kosse@filezilla-project.org> in
1854 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3651>.
1856 ** libgnutls: Fix PKCS#12 decryption from password.
1857 The encryption key derived from the password was incorrect for (on
1858 average) 1 in every 128 input for random inputs. Reported by "Kukosa,
1859 Tomas" <tomas.kukosa@siemens-enterprise.com> in
1860 <http://permalink.gmane.org/gmane.network.gnutls.general/1663>.
1862 ** libgnutls: Return correct bit lengths of some MPIs.
1863 gnutls_dh_get_prime_bits, gnutls_rsa_export_get_modulus_bits, and
1864 gnutls_dh_get_peers_public_bits. Before the reported value was
1865 overestimated. Reported by Peter Hendrickson <pdh@wiredyne.com> in
1866 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3607>.
1868 ** libgnutls: Avoid internal error when invoked after GNUTLS_E_AGAIN.

1870 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3671>
1872 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3670>.
1874 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
1875 Before we required that the runtime library used the same (or more
1876 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
1877 that the runtime usage is above the minimum required. Reported by
1878 Marco d'Itri <md@linux.it> via Andreas Metzler
1879 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.
1881 ** tests: Added new self-test pkcs12_s2k_pem to detect MPI bit length error.
1883 ** tests: Improved test vectors in self-test pkcs12_s2k.
1885 ** tests: Added new self-test dn2 to detect off-by-one size error.

1916 ** libgnutls: For CSRs, don't null pad integers for RSA/DSA value.
1917 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
1918 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
1920 Note: As a side effect of this change, the "public key identifier"
1921 value computed for a certificate using this version of GnuTLS will be
1922 different from values computed using earlier versions of GnuTLS.
1924 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
1925 ** optional SignatureAlgorithm parameter field.
1926 VeriSign rejected these CSRs. They are stricly speaking not needed
1927 since you need the signer's certificate to verify the certificate
1928 signature anyway. Reported by Wilankar Trupti
1929 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
1931 ** libgnutls: When checking openpgp self signature also check the signatures

2188 No offically supported interfaces have been modified or removed. The
2189 library should be completely backwards compatible on both the source
2192 The shared library no longer exports some symbols that have never been
2193 officially supported, i.e., not mentioned in any of the header files.
2199 Normally when symbols are removed, the shared library version has to
2200 be incremented. This leads to a significant cost for everyone using
2201 the library. Because none of the above symbols have ever been
2202 intended for use by well-behaved applications, we decided that the it
2203 would be better for those applications to pay the price rather than
2204 incurring problems on the majority of applications.
2206 If it turns out that applications have been using unofficial
2207 interfaces, we will need to release a follow-on release on the v2.8
2208 branch to exports additional interfaces. However, initial testing
2209 suggests that few if any applications have been using any of the
2212 Although not a new change compared to 2.6.x, we'd like to remind you
2213 interfaces have been modified so that X.509 chain verification now
2214 also checks activation/expiration times on certificates. The affected

2224 This change in behaviour was made during the GnuTLS 2.6.x cycle, and
2225 we gave our rationale for it in earlier release notes.

2381 No changes since last version.
2383 * Version 2.7.8 (released 2009-05-03)
2385 ** libgnutls: Fix DSA key generation.
2386 Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2388 ** libgnutls: Check expiration/activation time on untrusted certificates.
2389 Merged from stable branch. Reported by Romain Francoise
2390 <romain@orebokech.com>. This changes the semantics of
2391 gnutls_x509_crt_list_verify, which in turn is used by
2392 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
2393 We add two new gnutls_certificate_status_t codes for reporting the new
2394 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
2395 We also add a new gnutls_certificate_verify_flags flag,
2396 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2397 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
2399 ** lib: Linker version scripts reduces number of exported symbols.
2400 The linker version script now lists all exported ABIs explicitly, to
2401 avoid accidentally exporting unintended functions. Compared to
2402 before, most symbols beginning with _gnutls* are no longer exported.
2403 These functions have never been intended for use by applications, and
2404 there were no prototypes for these function in the public header
2405 files. Thus we believe it is possible to do this without incrementing
2406 the library ABI version which normally has to be done when removing an
2409 ** lib: Limit exported symbols on systems without LD linker scripts.
2410 Before all symbols were exported. Now we limit the exported symbols
2411 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
2412 _gnutls*. This is a superset of the actual supported ABI, but still
2413 an improvement compared to before. This is implemented using Libtool
2414 -export-symbols-regex. It is more portable than linker version
2417 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
2418 This should have been done in the last release.
2420 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
2421 Reported by Peter Hendrickson <pdh@wiredyne.com> in
2422 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
2424 ** doc: Improved sections for the info manual.
2425 We now follow the advice given by the texinfo manual on which
2426 directory categories to use. In particular, libgnutls moved from the
2427 'GNU Libraries' section to the 'Software libraries' and the command
2428 line tools moved from 'Network Applications' to 'System

2439 * Version 2.7.7 (released 2009-04-20)
2441 ** libgnutls: Applied patch by Cedric Bail to add functions
2442 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
2444 ** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.

2455 ** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
2456 It is currently only used by the core library. This will enable a new
2457 domain 'gnutls' for translations of the command line tools.
2459 ** Corrected possible memory corruption on signature verification failure.
2460 Reported by Miroslav Kratochvil <exa.exa@gmail.com>
2462 ** API and ABI modifications:
2463 gnutls_x509_crt_verify_hash: ADDED
2464 gnutls_x509_crt_get_verify_algorithm: ADDED
2466 * Version 2.7.6 (released 2009-02-27)
2468 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
2469 This applies both to generating certificates and certificate requests.
2471 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
2473 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
2474 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
2475 be used for chain verification.
2477 ** gnutls-serv: No longer disable MAC padding by default.
2478 Use --priority NORMAL:%COMPAT to disable MAC padding again.
2480 ** gnutls-cli: Certificate information output format changed.
2481 The tool now uses libgnutls' functions to print certificate
2482 information. This avoids code duplication.
2484 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
2485 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
2486 They can be used to override the default certificate chain validation
2489 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2490 specify the client hello message record version. Used to overcome buggy
2491 TLS servers. Report by Martin von Gagern.
2493 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
2495 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
2497 ** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
2499 ** API and ABI modifications:
2500 No changes since last version.
2502 * Version 2.7.5 (released 2009-02-06)
2504 ** libgnutls: Accept chains where intermediary certs are trusted.
2505 Before GnuTLS needed to validate the entire chain back to a
2506 self-signed certificate. GnuTLS will now stop looking when it has
2507 found an intermediary trusted certificate. The new behaviour is
2508 useful when chains, for example, contains a top-level CA, an
2509 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2510 To avoid chain validation errors due to the RSA-MD5 cert, you can
2511 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2512 The signature on trusted certificates are not checked, so the chain
2513 has a chance to validate correctly. Reported by "Douglas E. Engert"
2514 <deengert@anl.gov> in
2515 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2517 ** libgnutls: result_size in gnutls_hex_encode now holds
2518 the size of the result. Report by John Brooks <special@dereferenced.net>.
2520 ** libgnutls: gnutls_handshake when sending client hello during a
2521 rehandshake, will not offer a version number larger than the current.
2522 Reported by Tristan Hill <stan@saticed.me.uk>.
2524 ** libgnutls: Permit V1 Certificate Authorities properly.
2525 Before they were mistakenly rejected even though
2526 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2527 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2528 "Douglas E. Engert" <deengert@anl.gov> in
2529 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2531 ** API and ABI modifications:
2532 No changes since last version.
2534 * Version 2.7.4 (released 2009-01-07)
2536 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2537 This is a bugfix -- the previous attempt to do this from internal x509
2538 certificate verification procedures did not return the correct value
2539 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2540 <dkg@fifthhorseman.net> in
2541 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2542 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
2543 Gillmor <dkg@fifthhorseman.net>.
2545 ** libgnutls: New interface to get key id for certificate requests.
2546 Patch from David Marín Carreño <davefx@gmail.com> in
2547 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
2549 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
2551 ** certtool: --verify-chain now prints results of using library verification.
2552 Earlier, certtool --verify-chain used its own validation algorithm
2553 which wasn't guaranteed to give the same result as the libgnutls
2554 internal validation algorithm. Now this command print a new final
2555 line with header 'Chain verification output:' that contains the result
2556 from using the internal verification algorithm on the same chain.
2558 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
2560 ** API and ABI modifications:
2561 gnutls_x509_crq_get_key_id: ADDED.
2563 * Version 2.7.3 (released 2008-12-10)
2565 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
2566 Reported by Michael Kiefer <Michael-Kiefer@web.de> in
2567 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507633> forwarded by
2568 Andreas Metzler <ametzler@downhill.at.eu.org> in
2569 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
2571 ** libgnutls: Libgcrypt initialization changed.
2572 If libgcrypt has not already been initialized, GnuTLS will now
2573 initialize libgcrypt with disabled secure memory. Initialize
2574 libgcrypt explicitly in your application if you want to enable secure
2575 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
2576 allocation functions, which doesn't use secure memory, so there is no
2577 real change in behaviour.
2579 ** libgnutls: Fix memory leak in PSK authentication.
2580 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
2581 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
2583 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
2585 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
2586 It needs to be invoked before libgcrypt is initialized.
2588 ** gnutls-cli: Return non-zero exit code on error conditions.
2590 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
2592 ** tests: Added chainverify self-test that tests X.509 chain verifications.
2594 ** API and ABI modifications:
2595 No changes since last version.
2597 * Version 2.7.2 (released 2008-11-18)
2599 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
2600 The flaw makes it possible for man in the middle attackers (i.e.,
2601 active attackers) to assume any name and trick GnuTLS clients into
2602 trusting that name. Thanks for report and analysis from Martin von
2603 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
2605 Any updates with more details about this vulnerability will be added
2606 to <http://www.gnu.org/software/gnutls/security.html>
2608 ** libgnutls: Fix namespace issue with version symbols.
2609 The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
2610 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
2611 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
2612 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
2613 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
2614 work but are deprecated.
2616 ** certtool: allow setting arbitrary key purpose object identifiers.
2618 ** libgnutls: Fix detection of C99 macros, to make debug logging work again.
2620 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
2621 Reported by Kevin Quick <quick@sparq.org> in
2622 <https://savannah.gnu.org/support/index.php?106454>.

2629 ** libgnutls: Change detection of when to use a linker version script.
2630 Use --enable-ld-version-script or --disable-ld-version-script to
2631 override auto-detection logic.
2633 ** doc: Change license on the manual to GFDLv1.3+.

2732 * Version 2.6.6 (released 2009-04-30)
2734 ** libgnutls: Corrected double free on signature verification failure.
2735 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
2736 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
2738 ** libgnutls: Fix DSA key generation.
2739 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
2740 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
2741 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2743 ** libgnutls: Check expiration/activation time on untrusted certificates.
2744 Reported by Romain Francoise <romain@orebokech.com>. Before the
2745 library did not check activation/expiration times on certificates, and
2746 was documented as not doing so. We have realized that many
2747 applications that use libgnutls, including gnutls-cli, fail to perform
2748 proper checks. Implementing similar logic in all applications leads
2749 to code duplication. Hence, we decided to check whether the current
2750 time (as reported by the time function) is within the
2751 activation/expiration period of certificates when verifying untrusted
2754 This changes the semantics of gnutls_x509_crt_list_verify, which in
2755 turn is used by gnutls_certificate_verify_peers and
2756 gnutls_certificate_verify_peers2. We add two new
2757 gnutls_certificate_status_t codes for reporting the new error
2758 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
2759 add a new gnutls_certificate_verify_flags flag,
2760 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2763 More details about the vulnerabilities will be posted at
2764 <http://www.gnu.org/software/gnutls/security.html>.
2766 ** gnutls-cli, gnutls-cli-debug: Fix AIX build problem.
2767 Reported by LAUPRETRE François (P) <francois.laupretre@ratp.fr> in
2768 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3468>.
2770 ** tests: Fix linking of tests/openpgp/keyring self-test.
2771 Reported by Daniel Black in <https://savannah.gnu.org/support/?106543>.
2773 ** API and ABI modifications:
2774 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2775 gnutls_certificate_verify_peers: Likewise.
2776 gnutls_certificate_verify_peers2: Likewise.
2777 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
2778 GNUTLS_CERT_EXPIRED: ADDED.
2779 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2781 * Version 2.6.5 (released 2009-04-11)
2783 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2784 specify the client hello message record version. Used to overcome buggy
2785 TLS servers. Report by Martin von Gagern.
2787 ** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
2788 Libtasn1 0.3.4 or later is required. This is to align with the
2789 upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.
2791 ** API and ABI modifications:
2792 No changes since last version.
2794 * Version 2.6.4 (released 2009-02-06)
2796 ** libgnutls: Accept chains where intermediary certs are trusted.
2797 Before GnuTLS needed to validate the entire chain back to a
2798 self-signed certificate. GnuTLS will now stop looking when it has
2799 found an intermediary trusted certificate. The new behaviour is
2800 useful when chains, for example, contains a top-level CA, an
2801 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2802 To avoid chain validation errors due to the RSA-MD5 cert, you can
2803 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2804 The signature on trusted certificates are not checked, so the chain
2805 has a chance to validate correctly. Reported by "Douglas E. Engert"
2806 <deengert@anl.gov> in
2807 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2809 ** libgnutls: result_size in gnutls_hex_encode now holds
2810 the size of the result. Report by John Brooks <special@dereferenced.net>.
2812 ** libgnutls: gnutls_handshake when sending client hello during a
2813 rehandshake, will not offer a version number larger than the current.
2814 Reported by Tristan Hill <stan@saticed.me.uk>.
2816 ** libgnutls: Permit V1 Certificate Authorities properly.
2817 Before they were mistakenly rejected even though
2818 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2819 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2820 "Douglas E. Engert" <deengert@anl.gov> in
2821 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2823 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2824 This is a bugfix -- the previous attempt to do this from internal x509
2825 certificate verification procedures did not return the correct value
2826 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2827 <dkg@fifthhorseman.net> in
2828 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2829 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
2830 Gillmor <dkg@fifthhorseman.net>.

2844 Andreas Metzler <ametzler@downhill.at.eu.org> in
2845 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
2847 ** libgnutls: Fix memory leak in PSK authentication.
2848 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
2849 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
2851 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
2852 It needs to be invoked before libgcrypt is initialized.
2854 ** gnutls-cli: Return non-zero exit code on error conditions.
2856 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
2858 ** API and ABI modifications:
2859 No changes since last version.
2861 * Version 2.6.2 (released 2008-11-12)
2863 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
2864 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
2865 problem for certificate chains that contained just one self-signed
2866 certificate. Reported by Michael Meskes <meskes@debian.org> in
2867 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505279>.
2869 ** API and ABI modifications:
2870 No changes since last version.
2872 * Version 2.6.1 (released 2008-11-10)
2874 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
2875 The flaw makes it possible for man in the middle attackers (i.e.,
2876 active attackers) to assume any name and trick GnuTLS clients into
2877 trusting that name. Thanks for report and analysis from Martin von
2878 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
2880 Any updates with more details about this vulnerability will be added
2881 to <http://www.gnu.org/software/gnutls/security.html>
2883 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
2884 Reported by Kevin Quick <quick@sparq.org> in
2885 <https://savannah.gnu.org/support/index.php?106454>.

2893 Thanks to Thomas Viehmann <tv@beamnet.de> for report.
2895 ** certtool: Print a PKCS #8 key even if it is not encrypted.
2897 ** tests: Make tests compile when using internal libtasn1.
2898 Patch by ludo@gnu.org (Ludovic Courtès).

2905 ** libgnutls: Correct printing and parsing of IPv6 addresses.
2907 ** libgnutls-openssl: fix out of bounds access.
2908 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
2909 from Thomas Viehmann <tv@beamnet.de>.
2911 ** certtool: Use inet_pton for parsing IPv6 addresses.
2913 ** Major changes compared to the v2.4 branch:
2915 *** Added API to replace and update the crypto backend.
2917 *** certtool: can add several subject alternative names via template file.
2919 *** opencdk: Parse (but not decrypt) encrypted secret keys.
2921 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
2922 either set or append alternative names. It can also handle binary structures
2923 such as IP addresses.
2925 *** libgnutls: New function to set minimum acceptable SRP bits.
2926 The function is gnutls_srp_set_prime_bits.
2928 *** libgnutls: Add interface to deal with public key and signature algorithms.
2929 The functions are called gnutls_pk_list, gnutls_pk_get_id,
2930 gnutls_sign_list, and gnutls_sign_get_id.
2932 *** libgnutls: New interfaces to get name of public key and signing algorithms.
2933 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
2935 *** libgnutls: New API to get a string corresponding to a error symbol.
2936 The function is gnutls_strerror_name.
2938 *** libgnutls: New API to set the public parameters in a certificate request
2939 *** from a private key.
2940 The function is gnutls_x509_crq_set_key_rsa_raw.
2942 *** libgnutls: New API to set a callback to extract TLS Finished data.
2943 The function to register is gnutls_session_set_finished_function and
2944 it takes a callback of the gnutls_finished_callback_func type.
2946 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
2948 *** libgnutls: New interface to register a new TLS extension handler.
2949 The new function gnutls_ext_register can be used to register handlers
2950 for specific TLS extension types. The callback functions have the new
2951 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
2952 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
2955 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
2956 The function is gnutls_register_md5_handler. When libgcrypt is in
2957 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
2960 *** API/ABI changes in GnuTLS 2.6
2961 No functions have been removed or modified. The library should be
2962 fully backwards compatible on both the source and binary level.
2964 A new header file <gnutls/crypto.h> have been added. It contains
2965 definitions related to replacing the internal crypto functionality.
2966 All definitions and the header itself is experimental but supported.
2968 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
2969 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
2970 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
2972 The following functions have been added to libgnutls:
2976 gnutls_crypto_bigint_register2
2977 gnutls_crypto_cipher_register2
2978 gnutls_crypto_digest_register2

3015 The parameters are now allocated in the structure itself.
3017 ** doc: Texinfo HTML manual uses a stylesheet to improve readability.
3019 ** tests: Scripts now use EXEEXT properly.
3020 Modern libtool doesn't create wrapper script, so the self tests need
3021 to invoke certtool.exe under MinGW32+Wine.
3023 ** Uses autoconf 2.63, automake 1.10.1, libtool 2.2.6a.
3024 Automake warnings are now also enabled.

3027 gnutls_pk_params_st: MODIFIED
3029 * Version 2.5.8 (released 2008-09-21)
3031 ** certtool: updated so it can add several subject alternative names using
3034 ** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
3035 either set or append alternative names. It can also handle binary structures
3036 such as IP addresses.
3038 ** libgnutls: Fix crash in hashing code when using non-libgcrypt handlers.
3040 ** libgnutls: New function to set minimum acceptable SRP bits.
3041 The function is gnutls_srp_set_prime_bits. Tiny patch by Kevin Quick
3042 <quick@sparq.org> in <https://savannah.gnu.org/support/index.php?106454>.
3044 ** libgnutls: Check for overflows in gnutls_calloc and gnutls_secure_calloc.
3045 Also fix overflows in calls to those functions. Reported by Werner
3046 Koch <wk@gnupg.org>.

3089 The functions are called gnutls_pk_list, gnutls_pk_get_id,
3090 gnutls_sign_list, and gnutls_sign_get_id. Suggested by Sam
3091 Varshavchik <mrsam@courier-mta.com>.
3093 ** libgnutls: Refactor and clean up some code.
3095 ** libgnutls: Fix compile error with Sun CC.

3120 Reported by "jth.net ApS" <info@jth.net>.
3122 ** libgnutls: Fix segmentation fault when generating private keys.
3123 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
3125 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
3126 The code has not worked since v0.9.0 and apparently nobody has missed
3127 it, so we decided to remove the code rather than fix it. If you have
3128 old certificate chains stored in PKCS#7 format, you can convert them
3129 to a list of PEM certificates by using 'certtool --p7-info'. Reported
3130 by Christian Grothoff <christian@grothoff.org>.

3154 ** API and ABI modifications:
3155 No changes since last version.
3157 * Version 2.5.3 (released 2008-08-14)
3159 ** libgnutls: New API to set the public parameters in a certificate request
3160 ** from a private key.
3161 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
3162 discussion with "Zach C." <fxchip@gmail.com>.
3164 ** libgnutls: New API to set a callback to extract TLS Finished data.
3165 The function to register is gnutls_session_set_finished_function and
3166 it takes a callback of the gnutls_finished_callback_func type.
3168 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
3169 Reported in <https://savannah.gnu.org/support/?106453>.
3171 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
3172 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
3173 names are mapped to the new names in compat.h. These mappings will
3174 likely be removed more quickly than other mappings in that file due to
3175 the namespace violation.

3192 ** libgnutls: Fix bug in gnutls_dh_params_generate2.
3193 The prime and generator was swapped.
3195 ** libgnutls: New interface to register a new TLS extension handler.
3196 The new function gnutls_ext_register can be used to register handlers
3197 for specific TLS extension types. The callback functions have the new
3198 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
3199 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
3202 ** Move more code for TLS/IA extension from libgnutls to libgnutls-extra.
3203 This was made possible by using the new gnutls_ext_register interface.
3204 The TLS/IA functionality has only been supported through the
3205 libgnutls-extra library, so it makes sense for the code to belong
3208 ** API and ABI modifications:
3209 gnutls_ext_recv_func: ADDED
3210 gnutls_ext_send_func: ADDED
3211 gnutls_ext_parse_type_t: ADDED

3218 ** API and ABI modifications:
3219 No changes since last version.
3221 * Version 2.5.0 (released 2008-07-02)
3223 ** Port fixes from v2.4.1 release, see below.
3225 ** Added API to replace and update the crypto backend.
3226 The header gnutls/crypto.h is now officially supported, and declares
3229 ** Rewritten opencdk crypto backend, to use the gnutls internal one.
3231 ** Update gnulib and translations.
3232 The gnulib gc crypto code has been removed since it was never finished
3233 and is no longer even used. An internal non-libgcrypt crypto
3234 implementation may be added in the future, but we'll decide that later
3237 ** API and ABI modifications:
3238 gnutls_crypto_bigint_register2: ADDED.
3239 gnutls_crypto_cipher_register2: ADDED.
3240 gnutls_crypto_digest_register2: ADDED.
3241 gnutls_crypto_mac_register2: ADDED.
3242 gnutls_crypto_pk_register2: ADDED.

3245 gnutls_crypto_single_digest_register2: ADDED.
3246 gnutls_crypto_single_mac_register2: ADDED.
3248 * Version 2.4.3 (released 2009-02-06)
3250 ** libgnutls: Accept chains where intermediary certs are trusted.
3251 Before GnuTLS needed to validate the entire chain back to a
3252 self-signed certificate. GnuTLS will now stop looking when it has
3253 found an intermediary trusted certificate. The new behaviour is
3254 useful when chains, for example, contains a top-level CA, an
3255 intermediary CA signed using RSA-MD5, and an end-entity certificate.
3256 To avoid chain validation errors due to the RSA-MD5 cert, you can
3257 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
3258 The signature on trusted certificates are not checked, so the chain
3259 has a chance to validate correctly. Reported by "Douglas E. Engert"
3260 <deengert@anl.gov> in
3261 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3263 ** libgnutls: Permit V1 Certificate Authorities properly.
3264 Before they were mistakenly rejected even though
3265 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
3266 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
3267 "Douglas E. Engert" <deengert@anl.gov> in
3268 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3270 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
3271 This is a bugfix -- the previous attempt to do this from internal x509
3272 certificate verification procedures did not return the correct value
3273 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
3274 <dkg@fifthhorseman.net> in
3275 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,

3357 ** API and ABI modifications:
3358 No changes since last version.
3360 * Version 2.4.0 (released 2008-06-19)
3362 ** Major changes compared to the v2.2 branch:
3364 *** The OpenPGP sub-system has been improved and now supports subkeys.
3366 *** The PSK sub-system has been improved and now supports password
3367 *** derivation and PSK identity hints.
3368 The password derivation algorithms support is documented in
3369 draft-ietf-netconf-tls-02.txt.
3371 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
3372 This aligns terminology with OpenPGP, which doesn't use DER encoding.
3373 The old parameters will continue to work for some time.
3375 *** Certtool now confirm passwords and changes permissions of private key files.
3377 *** The default handshake size limit has been increased to 48kb.
3378 It appears as if some valid handshakes are large due to sending many
3379 CA certificates. (The earlier limit was 16kb.)
3381 *** LZO compression is now disabled by default.
3382 The main reason is that LZO compression in TLS is not standardized,
3383 but license compatiblity issues with minilzo triggered us to make this
3386 *** Improvements for cross-compilation to Windows and OpenWRT.
3388 *** The look of the GTK-DOC manual has been improved.
3389 Major developer visible changes compared to the v2.2 branch:
3391 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
3393 *** New APIs to access the raw X.509 Subject and Issuer DN's and
3394 *** elements from the certificate credentials structure.
3395 Thanks to Joe Orton.
3397 *** New APIs to improve working with username/passwords and PSK.
3399 *** Names of constants to affect certificate printing changed.
3400 The constants are used for OpenPGP too, which the names didn't
3401 reflect, so the following name change has been made:
3404 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
3405 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
3406 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
3408 The old names will be mapped to the new names for some time.
3410 *** The function gnutls_openpgp_privkey_get_id has been renamed to
3411 *** gnutls_openpgp_privkey_get_key_id.
3412 A compatibility mapping exists to avoid breaking API backwards
3415 *** Replaced all uses of alloca with malloc and free.
3417 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
3418 We have been unable to find a documented rationale for this practice.
3420 *** Of course, many smaller fixes have been made, see the ChangeLog file.
3422 *** API/ABI changes in GnuTLS 2.4
3423 All OpenPGP related functions have been moved from libgnutls-extra to
3424 libgnutls, and several new functions have been added (see below).
3425 Before making the release, we discussed whether moving functions from
3426 libgnutls-extra to libgnutls would require us to increment the ABI
3427 version, but the general opinion was that this would not be required.
3428 All older functions continue to work the same. We are open to the
3429 possibility that this decision will lead to problem on some platform,
3430 and if it turns out that the Right Thing should have been to increment
3431 the shared library version, we would need to release an update within
3432 the 2.4.x branch that increments the shared library version.
3434 This release adds the following functions:
3436 gnutls_psk_client_get_hint
3437 gnutls_psk_set_server_credentials_hint
3438 gnutls_psk_netconf_derive_key
3440 Used to get/set the PSK identity hint, and derive PSK keys from
3441 passwords a'la netconf.
3443 gnutls_x509_dn_deinit
3444 gnutls_x509_dn_export
3445 gnutls_x509_dn_import
3448 Used to handle X.509 Certificate DN's directly.
3452 Converts a data buffer to hex. Useful for handling PSK/SRP shared
3455 gnutls_certificate_get_x509_cas
3456 gnutls_certificate_get_x509_crls
3457 gnutls_certificate_get_openpgp_keyring
3459 Functions for direct access to credential elements.

3500 gnutls_openpgp_privkey_set_preferred_key_id
3502 New OpenPGP related functions.
3504 The function gnutls_openpgp_crt_get_key_id is the same as the old
3505 from gnutls_openpgp_crt_get_id, see above.
3507 The release also adds a new header file 'gnutls/crypto.h', however it
3508 is currently not used.

3542 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
3544 ** doc/: Add psktool to info index. Some minor cleanups.
3546 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
3548 ** tests/: Added libgcrypt.supp which can be used with valgrind.
3549 The file suppresses the known libgcrypt memory leaks, so they aren't
3550 printed when you run valgrind on the gnutls self-tests. Use it as
3551 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add

3575 The function is gnutls_psk_set_server_credentials_hint.
3577 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
3578 In the client, the message is parsed and the application can use
3579 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
3580 message is sent if the application has specified a PSK identity hint
3581 using gnutls_psk_set_server_credentials_hint.
3583 *** libgnutls [PSK]: Support Netconf PSK key derivation.
3584 The function gnutls_psk_netconf_derive_key supports the PSK key
3585 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
3588 *** psktool: Support new --netconf-hint to generate PSK key from password.
3589 Uses the Netconf algorithm to derive PSK key from password.
3591 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
3593 *** gnutls-cli: Always support PSK modes, through a callback.
3594 The callback will derive a PSK key using Netconf algorithm. It will
3595 print the PSK identity hint to help the user.

3650 *** [GNUTLS-SA-2008-1-1]
3651 *** libgnutls: Fix crash when sending invalid server name.
3652 The crash can be triggered remotely before authentication, which can
3653 lead to a Daniel of Service attack to disable the server. The bug
3654 cause gnutls to store more session resumption data than what was
3655 allocated for, thus overwriting unallocated memory.
3657 *** [GNUTLS-SA-2008-1-2]
3658 *** libgnutls: Fix crash when sending repeated client hellos.
3659 The crash can be triggered remotely before authentication, which can
3660 lead to a Daniel of Service attack to disable the server. The bug
3661 triggers a null-pointer dereference.
3663 *** [GNUTLS-SA-2008-1-3]
3664 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3665 The crash can be triggered remotely before authentication, which can
3666 lead to a Daniel of Service attack to disable the server. The bug
3667 cause gnutls to read memory beyond the end of the received record.
3669 ** libgnutlsxx: Updated API according to patches from Eduardo
3670 Villanueva Che (discussion at
3671 <http://lists.gnu.org/archive/html/gnutls-devel/2007-02/msg00017.html>)
3673 ** Use umask to restrict permissions to owner before creating a file.
3675 ** API and ABI modifications:
3676 No changes since last version.
3678 * Version 2.3.9 (released 2008-05-16)
3680 ** libgnutls: Fix build failures if SRP/OpenPGP is disabled.
3681 Based on report and tiny patches from
3682 <jared.jennings.ctr@eglin.af.mil>, see
3683 <https://savannah.gnu.org/support/index.php?106342>.
3685 ** libgnutls: Translation fixes.
3687 ** gnutls-cli: Fix so that PSK authentication works.
3688 Also improve manual to give example for gnutls-cli PSK authentication.
3690 ** certtool: Encrypting a private key now require a confirmed password.
3691 Before './certtool -k -8' would merely ask for a password once.
3692 Reported by Daniel 'NebuchadnezzaR' Dehennin
3693 <nebuchadnezzar@asgardr.info> see
3694 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
3696 ** certtool: When writing private keys to files, change permissions of file.
3697 Now the file which the private key is saved to is chmod'ed 0600.
3698 Reported by martin f krafft <madduck@debian.org> see
3699 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
3701 ** guile: Fix -fgnu89-inline test.
3703 ** Removed --enable-profile-mode.
3704 The code linked gnutls with the libfc project (Function Check) which
3705 appears to have been stalled since around 2002.
3707 ** Clean up header file checks by ./configure.
3709 ** Update of gnulib files.
3711 ** API and ABI modifications:
3712 No changes since last version.
3714 * Version 2.3.8 (released 2008-04-29)
3716 ** libgnutls: Increase default handshake packet size limit to 48kb.
3717 The old limit was 16kb and some servers send huge list of trusted CAs,
3718 thus running into the limit. FYI, applications can further increase
3719 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3720 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3721 <marc@mclemente.net> for reporting and providing test servers.
3723 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
3724 Returned when the handshake data size is too large. Before
3725 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
3728 ** libgnutls: Hide definitions in crypto.h.
3729 We have decided that the APIs defined in crypto.h are not stable
3730 enough for v2.4, so don't use any of those functions.
3732 ** gnutls-cli: exit when hostname doesn't match certificate.
3733 Use --insecure to avoid hostname comparison.
3735 ** certtool: --inder and --outder replaced by --inraw and --outraw.
3736 The reason is to align terminology with OpenPGP, which doesn't use
3737 DER. The old parameters will continue to work for some time.
3739 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
3741 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
3743 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
3744 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
3745 vasprintf symbol from the libgcrypt library which caused problems.
3747 ** Update of gnulib files.
3749 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
3751 ** API and ABI modifications:
3752 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
3754 * Version 2.3.7 (released 2008-04-21)
3756 ** opencdk now properly sets the key usage bits into openpgp keys.
3758 ** gnutls-cli: Fix crash on TLS handshake failures.
3759 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
3760 This is similar to <http://bugs.debian.org/429183>.
3762 ** certtool: with --generate-request and newly generated keys, print the key.
3764 ** Build fixes for MinGW.
3765 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
3766 with -lws2_32 when needed. Use ASCII only isprint() when printing
3767 X.509 certificate information, to avoid non-ASCII but printable
3768 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
3771 ** Update internal copy of libtasn1 to version 1.4.
3773 ** API and ABI modifications:
3774 No changes since last version.
3776 * Version 2.3.6 (released 2008-04-17)
3778 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
3779 ** Improve documentation for gnutls_x509_crq_sign2.
3780 Based on report from "John Brooks" <aspecialj@gmail.com> in
3781 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
3783 ** tests/pathlen: run diff without parameters to improve portability.
3784 Based on HPUX build hints in
3785 <http://hpux.cs.utah.edu/hppd/cgi-bin/wwwtar?/hpux/Gnu/gnutls-2.3.4/gnutls-2.3.4-src-11.11.tar.gz+gnutls-2.3.4/HPUX.Install+text>.
3787 ** Don't use %e specifier with strftime, it doesn't work under Windows.
3788 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3789 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3791 ** Remove all uses of gnutls_alloca/gnutls_afree.
3792 Use normal gnutls_malloc instead. One reason is increased portability
3793 to Windows, the other is that several of the uses may be unsafe
3794 because the size of data allocated could be large. Reported by
3795 Massimo Gaspari <massimo.gaspari@alice.it> in
3796 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3798 ** Build Guile code with -fgnu89-inline only when supported.
3799 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
3800 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
3802 ** Several GTK-DOC related fixes.
3804 ** Clean up OpenCDK related code.
3805 GnuTLS now requires its internal OpenCDK code rather than the external
3806 GPL library OpenCDK. Unfortunately, we don't have resources to
3807 maintain an external library (help welcome).
3809 ** API and ABI modifications:
3810 No changes since last version.
3812 * Version 2.3.5 (released 2008-04-14)
3814 ** Build fix for MinGW and --disable-shared.
3815 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3816 <http://permalink.gmane.org/gmane.network.gnutls.general/1145>.
3818 ** Document how to generate CRLs.
3819 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
3821 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3823 ** Several minor fixes in the OpenPGP interface.
3824 Thanks to Daniel Kahn Gillmor.
3826 ** Fix fopen file descriptor leak in PSK server code.
3827 Thanks to Laurence Withers <l@lwithers.me.uk>, see
3828 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
3830 ** Translations files not stored directly in git to avoid merge conflicts.
3832 ** New APIs to let applications replace the RNG used.
3833 Update all RNG callers in the code to use the new interface.
3835 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
3837 ** Update gnulib files.
3839 ** API and ABI modifications:
3840 gnutls_crypto_rnd_register: ADDED
3841 gnutls_rnd_level_t: ADDED
3842 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
3843 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
3844 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
3845 gnutls_crypto_rnd_st: ADDED
3846 GNUTLS_DIG_SHA224: ADDED
3847 GNUTLS_SIGN_RSA_SHA224: ADDED
3848 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
3850 * Version 2.3.4 (released 2008-03-19)
3852 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
3853 They weren't renamed in the public header file.
3855 ** Added functions to register a cipher/mac/digest. This allows to
3856 override the included ones.
3858 ** Fix a bunch of compiler warnings.
3860 ** API and ABI modifications:
3861 gnutls_crypto_cipher_st: ADDED
3862 gnutls_crypto_mac_st: ADDED
3863 gnutls_crypto_digest_st: ADDED
3864 gnutls_crypto_cipher_register: ADDED
3865 gnutls_crypto_mac_register: ADDED
3866 gnutls_crypto_digest_register: ADDED
3867 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
3869 * Version 2.3.3 (released 2008-03-10)
3871 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
3872 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
3874 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
3875 We could not find any modern justification for enabling these flags by
3876 default. If you know of some platform that needs one of the flags to
3877 work properly, please let us know. (Actually introduced in v2.3.0 but
3878 not documented until now.)
3880 ** Importing many CA certificates are now considerably faster.
3881 This affect gnutls_certificate_set_x509_trust_mem,
3882 gnutls_certificate_set_x509_trust, and
3883 gnutls_certificate_set_x509_trust_file. The complexity was reduced
3884 from O(2*n^2) to O(n). When adding 206 files containing 408
3885 certificates, using gnutls_certificate_set_x509_trust_file, the time
3886 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
3887 to trigger the problem. See also
3888 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
3890 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
3891 ** to be explicit that it takes zero terminated data.
3893 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.
3895 ** Documentation fixes for the GTK-DOC manual.
3897 ** Fix compilation error related to __FUNCTION__ on some systems.
3898 Reported by Tim Mooney, see
3899 <https://savannah.gnu.org/support/?106267>.
3901 ** Updated translations.
3903 ** Update gnulib files.
3905 ** API and ABI modifications:
3906 gnutls_hex2bin: MODIFIED, uses size_t instead of int for string length,
3907 and char* instead of void* for output buffer.
3909 * Version 2.3.2 (released 2008-02-26)
3911 ** Fix srcdir!=objdir failure in openpgpself test.
3913 ** Improved API documentation output from GTK-DOC.
3915 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
3917 ** Renamed gnutls_certificate_export_x509_cas and friends.
3918 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.
3920 ** Internal header files cleanup.
3922 ** API and ABI modifications:
3923 gnutls_certificate_export_x509_cas: RENAMED to gnutls_certificate_get_x509_cas
3924 gnutls_certificate_export_x509_crls: RENAMED to gnutls_certificate_get_x509_crls
3925 gnutls_certificate_export_openpgp_keyring: RENAMED to gnutls_certificate_get_openpgp_keyring
3926 gnutls_x509_dn_export: ADDED
3928 * Version 2.3.1 (released 2008-02-21)
3930 ** OpenPGP support merged into libgnutls and is now licensed under LGPL.
3931 The included copy of OpenCDK has been stripped down and re-licensed
3934 ** Cipher priority string handling now handle strings that starts with NULL.
3935 Thanks to Laurence Withers <l@lwithers.me.uk>.
3937 ** gnutls-cli: When -d is used, also prints RNG information from libgcrypt.
3939 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
3942 ** Increased the default certificate verification chain limits and allowed
3943 for checks without limitation.
3945 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
3946 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
3947 strings and return the proper size.
3949 ** Add section 'On Record Padding' to the manual.
3950 This collects all problems related to record padding with
3951 Nokia/Sony-Ericsson phones that we know about.
3953 ** Several improvements in the OpenPGP authentication.
3954 Now subkeys can be used for authentication, according to
3955 draft-mavrogiannopoulos-rfc5081bis-00.txt.
3957 ** certtool can print information on OpenPGP certificates and keys.
3959 ** Added gnutls_x509_dn_import/init/deinit() to access raw DER DN.
3962 ** Added gnutls_certificate_export_x509_cas and other functions to
3963 export elements from the certificate credentials structure. Based on
3964 suggestion from Joe Orton.
3967 Clarify that srp_base64 is not the same as normal base64.
3969 ** Fix non-portable use of brace expansion in makefiles.
3971 ** API and ABI modifications:
3972 gnutls_certificate_export_x509_cas: ADDED
3973 gnutls_certificate_export_x509_crls: ADDED
3974 gnutls_certificate_export_openpgp_keyring: ADDED
3975 gnutls_openpgp_keyid_t: ADDED, instead of hard-coded 'unsigned char[8]'.
3976 gnutls_openpgp_crt_get_key_id: ADDED, obsoletes gnutls_openpgp_crt_get_id.
3977 gnutls_openpgp_crt_get_revoked_status: ADDED
3978 gnutls_openpgp_crt_get_subkey_count: ADDED
3979 gnutls_openpgp_crt_get_subkey_idx: ADDED
3980 gnutls_openpgp_crt_get_subkey_revoked_status: ADDED
3981 gnutls_openpgp_crt_get_subkey_pk_algorithm: ADDED
3982 gnutls_openpgp_crt_get_subkey_creation_time: ADDED
3983 gnutls_openpgp_crt_get_subkey_expiration_time: ADDED
3984 gnutls_openpgp_crt_get_subkey_id: ADDED
3985 gnutls_openpgp_crt_get_subkey_usage: ADDED
3986 gnutls_openpgp_privkey_get_fingerprint: ADDED
3987 gnutls_openpgp_privkey_get_key_id: ADDED

4013 GNUTLS_CRT_PRINT_ONELINE: ADDED, same as old GNUTLS_X509_CRT_ONELINE.
4014 GNUTLS_CRT_PRINT_UNSIGNED_FULL: ADDED, same as
4015 old GNUTLS_X509_CRT_UNSIGNED_FULL.
4017 * Version 2.3.0 (released 2008-01-08)
4019 ** LZO compression is now disabled by default.
4020 The reason is that LZO compression is not standardized in TLS. If you
4021 wish to experiment with it, you will have to supply --with-lzo when
4022 invoking ./configure. The internal copy of minilzo is no longer
4023 included with GnuTLS, so you will need to install liblzo or liblzo2 on
4024 your system to have --with-lzo to be effective.
4026 ** More than one server name field is now sent to the server properly.
4027 Thanks to mark.phillips@virgin.net.
4029 ** Fixes the post_client_hello_function(). The extensions are now parsed
4030 in a callback friendly way.
4032 ** Fix for certificate selection in servers with certificate callbacks.
4034 ** Updated translations.
4036 ** Update gnulib files.
4038 ** API and ABI modifications:
4039 No changes since last version.
4041 * Version 2.2.5 (released 2008-05-19)
4043 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
4044 The flaw would result in incorrectly terminated sessions with the
4045 error "Decryption has failed" when the server sends a small packet
4046 (typically when the session is closed). Reported by Andreas Metzler
4047 <ametzler@downhill.at.eu.org> in
4048 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
4050 ** API and ABI modifications:
4051 No changes since last version.
4053 * Version 2.2.4 (released 2008-05-19)
4055 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]

4136 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
4138 ** Fixes the post_client_hello_function(). The extensions are now parsed
4139 in a callback friendly way.
4141 ** Fix for certificate selection in servers with certificate callbacks.
4143 ** API and ABI modifications:
4144 No changes since last version.
4146 * Version 2.2.0 (released 2007-12-14)
4148 ** Update internal copy of libtasn1 to version 1.2.
4150 ** Certtool --verify-chain now handle inputs larger than 64kb.
4151 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
4152 recent versions of libgcrypt. The problem was that Wine with the
4153 libgcrypt RNG generates huge amounts of debugging output.
4155 ** Translation updates.
4156 Added Dutch translation. Updated Polish and Swedish translation.
4158 ** Major changes compared to the v2.0 branch:
4160 *** SRP support aligned with newly published RFC 5054.
4162 *** OpenPGP support aligned with newly published RFC 5081.
4164 *** Support for DSA2 keys.
4166 *** Support for Camellia cipher.
4168 *** Support for Opaque PRF Input extension.
4170 *** PKCS#8 parser now handle DSA keys.
4172 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
4173 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
4174 versions, such as 2.01 which is included with GnuTLS, is available
4175 under GPLv2 or later. If this incompatibility causes problems, we
4176 recommend you to disable LZO using --without-lzo. LZO compression is
4177 not a standard TLS compression algorithm, so the impact should be
4180 *** Functions for disabling record protocol padding.
4181 Works around bugs on Nokia/Ericsson phones.
4183 *** New functions gnutls_priority_set() for setting cipher priorities easily.
4184 Priorities like "COMPAT" also enables other work arounds, such as
4187 *** Other minor improvements and bug fixes.
4189 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
4190 To adapt to changes in the TLS extension specifications for OpenPGP
4191 and SRP, the GnuTLS API had to be modified. This means breaking the
4192 API and ABI backwards compatibility. That is something we try to
4193 avoid unless it is necessary. We decided to also remove the already
4194 deprecated stub functions for X.509 to XML conversion and TLS
4195 authorization (see below) when we had the opportunity.
4197 Generally, most applications does not need to be modified. Just
4198 re-compile them against the latest GnuTLS release, and it should work
4201 Applications that use the OpenPGP or SRP features needs to be
4202 modified. Below is a list of the modified APIs and discussion of what
4203 the minimal things you need to modify in your application to make it
4204 work with GnuTLS 2.2.
4206 Note that GnuTLS 2.2 also introduces new APIs -- such as
4207 gnutls_set_priority() that is superior to
4208 gnutls_set_default_priority() -- that you may want to start using.
4209 However, using those new APIs is not required to use GnuTLS 2.2 since
4210 the old functions continue are still supported. This text only
4211 discuss what you minimally have to modify.
4213 *** XML related changes
4214 The function `gnutls_x509_crt_to_xml' has been removed. It has been
4215 deprecated and only returned an error code since GnuTLS version
4216 1.2.11. Nobody has complained, so users doesn't seem to miss the
4217 functionality. We don't know of any other library to convert X.509
4218 certificates into XML format, but we decided (long ago) that GnuTLS
4219 isn't the right place for this kind of functionality. If you want
4220 help to find some other library to use here, please explain and
4221 discuss your use case on help-gnutls@gnu.org.
4223 *** TLS Authorization related changes
4224 Everything related to TLS authorizations have been removed, they were
4225 only stub functions that returned an error code:
4227 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
4228 gnutls_authz_data_format_type_t
4229 gnutls_authz_recv_callback_func
4230 gnutls_authz_send_callback_func
4232 gnutls_authz_send_x509_attr_cert
4233 gnutls_authz_send_saml_assertion
4234 gnutls_authz_send_x509_attr_cert_url
4235 gnutls_authz_send_saml_assertion_url
4237 *** SRP related changes
4238 The callback gnutls_srp_client_credentials_function has a new
4239 prototype, and its semantic has changed. You need to rewrite the
4240 callback, see the updated function documentation and SRP example code
4241 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
4244 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
4245 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
4246 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
4247 used. There are #define's to map the old names to the new. You may
4248 run into problems if you have a switch-case with cases for both SRP
4249 alerts, since they are now mapped to the same value. The solution is
4250 to drop the SRP alerts from such switch cases, as they are now
4251 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
4253 *** OpenPGP related changes
4254 The function `gnutls_certificate_set_openpgp_keyserver' have been
4255 removed. There is no replacement functionality inside GnuTLS. If you
4256 need keyserver functionality, consider using the GnuPG tools.
4258 All functions, types, and error codes related to OpenPGP trustdb
4259 format have been removed. The trustdb format is a non-standard
4260 GnuPG-specific format, and we recommend you to use key rings instead.
4261 The following have been removed:
4263 gnutls_certificate_set_openpgp_trustdb
4264 gnutls_openpgp_trustdb_init
4265 gnutls_openpgp_trustdb_deinit
4266 gnutls_openpgp_trustdb_import
4267 gnutls_openpgp_key_verify_trustdb
4268 gnutls_openpgp_trustdb_t
4269 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
4271 The following functions has an added parameter of the (new) type
4272 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
4273 (binary or base64). The functions are:
4274 gnutls_certificate_set_openpgp_key_file
4275 gnutls_certificate_set_openpgp_key_mem
4276 gnutls_certificate_set_openpgp_keyring_mem
4277 gnutls_certificate_set_openpgp_keyring_file
4279 To improve terminology and align with the X.509 interface, some
4280 functions have been renamed. Compatibility mappings exists. The old
4281 and new names of the affected functions and types are:
4284 gnutls_openpgp_key_t gnutls_openpgp_crt_t
4285 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
4286 gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
4287 GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
4288 GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
4289 gnutls_openpgp_key_init gnutls_openpgp_crt_init
4290 gnutls_openpgp_key_deinit gnutls_openpgp_crt_deinit
4291 gnutls_openpgp_key_import gnutls_openpgp_crt_import
4292 gnutls_openpgp_key_export gnutls_openpgp_crt_export
4293 gnutls_openpgp_key_get_key_usage gnutls_openpgp_crt_get_key_usage
4294 gnutls_openpgp_key_get_fingerprint gnutls_openpgp_crt_get_fingerprint
4295 gnutls_openpgp_key_get_pk_algorithm gnutls_openpgp_crt_get_pk_algorithm
4296 gnutls_openpgp_key_get_name gnutls_openpgp_crt_get_name
4297 gnutls_openpgp_key_get_version gnutls_openpgp_crt_get_version
4298 gnutls_openpgp_key_get_creation_time gnutls_openpgp_crt_get_creation_time
4299 gnutls_openpgp_key_get_expiration_time gnutls_openpgp_crt_get_expiration_time
4300 gnutls_openpgp_key_get_id gnutls_openpgp_crt_get_id
4301 gnutls_openpgp_key_check_hostname gnutls_openpgp_crt_check_hostname
4302 gnutls_openpgp_send_key gnutls_openpgp_send_cert
4304 ** API and ABI modifications:
4305 No changes since last version.
4307 * Version 2.1.8 (released 2007-12-10)
4309 ** The GPL version has been changed from version 2 to version 3.
4310 This affects the self-tests, command-line tools, the libgnutls-extra
4311 library, the relevant guile parts, and the build environment.
4313 ** Added gnutls_x509_crt_get_subject_alt_name2().
4315 ** Corrected a segfault when setting an empty gnutls_priority_t
4316 at gnutls_priority_set().
4318 ** Use gettext 0.17 which updates m4/lib-*.m4 macros.
4319 Fixes a problem with spurious -L/usr/lib additions.
4321 ** API and ABI modifications:
4322 gnutls_x509_crt_get_subject_alt_name2: ADD.
4324 * Version 2.1.7 (released 2007-11-29)
4326 ** PKCS #8 parser can now encode/decode DSA keys.
4328 ** Updated gnutls_set_default_priority2() now renamed to
4329 gnutls_priority_set() and gnutls_priority_set_direct() which
4330 accept a string to indicate preferences of ciphersuite parameters.
4332 ** gnutls-cli and gnutls-serv now have a --priority option to set
4333 the priority string.
4335 ** The gnutls_*_convert_priority() functions were deprecated by
4336 the gnutls_priority_set() and gnutls_priority_set_direct().
4338 ** Internal copy of OpenCDK upgraded to version 0.6.6.
4340 ** API and ABI modifications:

4371 * Version 2.1.6 (released 2007-11-15)
4373 ** Corrected bug in decompression of expanded compression data.
4375 ** Added the --to-p8 option to certtool to convert private keys
4378 ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code.
4380 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
4383 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
4384 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
4385 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
4386 documented. This caused some problems (e.g., debian #450854). To
4387 avoid backwards compatibility problems, this release revert this
4388 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
4389 done in GnuTLS 2.0.x and earlier, and add a new error code
4390 GNUTLS_E_UNKNOWN_ALGORITHM.
4392 ** Fixes several gtk-doc warnings.
4394 ** API and ABI modifications:
4395 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
4396 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
4397 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
4399 * Version 2.1.5 (released 2007-11-01)
4401 ** Fix PKCS#3 parameter export problem.
4403 ** Improve certtool queries, they now print the default value.
4407 ** Update gnulib files.
4409 ** API and ABI modifications:
4410 No changes since last version.
4412 * Version 2.1.4 (released 2007-10-27)
4414 ** Added the --v1 option to certtool, to allow generating X.509
4415 version 1 certificates.
4417 ** certtool: Add option --disable-quick-random to enable the old behaviour
4418 of using /dev/random to generate keys.
4420 ** Added priority functions that accept strings.
4422 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
4423 priorities preferences.
4425 ** Added gnutls_record_disable_padding() to allow servers talking to
4426 buggy clients that complain if the TLS 1.0 record protocol padding is
4429 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
4430 all supported compatibility options (like disabling padding).
4432 ** The gnutls_certificate_set_openpgp_* functions were modified to include
4433 the format. This makes the interface consistent with the x509 functions.
4435 ** Internal copy of OpenCDK upgraded to version 0.6.5.

4476 ** TLS authorization support removed.
4477 This technique may be patented in the future, and it is not of crucial
4478 importance for the Internet community. After deliberation we have
4479 concluded that the best thing we can do in this situation is to
4480 encourage society not to adopt this technique. We have decided to
4481 lead the way with our own actions.

4501 * Version 2.1.2 (released 2007-10-14)
4503 ** Removed all the trustdb code from openpgp authentication.
4504 We now use only the well-specified keyrings.
4506 ** The 256 bit ciphers are not enabled in the default priorities.

4545 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
4546 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
4547 compiled with Camellia support. See the libgcrypt documentation on
4548 how to enable it. Unconditionally disable it using the configure
4549 option --disable-camellia. Fixes #1.

4558 ** Support for draft-rescorla-tls-opaque-prf-input-00.txt.
4559 The support is disabled by default. Since no value has been allocated
4560 by the IANA for this extension yet, you will need to provide one
4561 yourself by invoking './configure --enable-opaque-prf-input=42'.

4617 ** New directory doc/credentials/ with test credentials.
4618 This collects the test credentials from the web page and from src/.
4619 The script gnutls-http-serv has also been moved to that directory.
4621 ** Update SRP extension type and cipher suite with official IANA values.
4622 This breaks backwards compatibility with SRP in older versions of
4623 GnuTLS, but this is intentional to speed up the adoption of the
4624 official values. The old values we used were incorrect.

4645 This solves connection problems in mutt, see
4646 <http://bugs.debian.org/439640>.
4648 ** Update gnulib files.
4649 In particular, the getpass module -- with its dependencies on getline,
4650 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
4651 library) directory to the gl/ directory (only used by the command line
4652 tools). The reason is that getpass is now only used by the
4653 command-line tools, and reducing the number of gnulib modules linked
4654 to the core library helps portability and reduces size.
4658 ** Disable building of PGP examples if PGP is disabled.
4660 ** Included copy of OpenCDK upgraded to version 0.6.4.
4662 ** API and ABI modifications:
4663 No changes since last version.
4665 * Version 1.7.18 (released 2007-08-16)
4667 ** Install images for the info manual.
4668 This has a side effect of renaming the images. See
4669 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
4670 discussions on the approach chosen.
4672 ** Fix pointer mix to variables of different size.
4673 Patch extracted from
4674 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
4676 ** Fix warnings during build.
4677 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
4679 ** API and ABI modifications:
4680 No changes since last version.
4682 * Version 1.7.17 (released 2007-08-15)
4684 ** New functions to perform external signing.
4685 Set the signing callback function (of the gnutls_sign_func prototype)
4686 using the gnutls_sign_callback_set function. In the callback, you may
4687 find the new functions gnutls_x509_privkey_sign_hash and
4688 gnutls_openpgp_privkey_sign_hash useful. A new function
4689 gnutls_sign_callback_get is also added, to retrieve the function
4690 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
4691 comments and testing.
4693 ** New self test of client and server authenticated X.509 TLS sessions.
4694 See tests/x509self.c and tests/x509signself.c. The latter also tests
4695 the new external signing callback interface.
4697 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
4698 These two actually describe the outer limits of a range of error codes
4699 reserved to the application. All of the errors are treated as fatal
4700 by the library (it has to since it doesn't know the semantics of the
4701 error codes). This can be useful in callbacks, to signal some
4702 application-specific error condition, which will usually eventually
4703 cause some gnutls API to return the same error code as the callback,
4704 which then can be inspected by the application. Note that error codes
4707 ** gnutls_set_default_priority now disable TLS 1.2 by default.
4708 The RFC is not released yet, and we're approaching a major release so
4709 let's not enable it just yet.
4711 ** Fix namespace so that gnutls_*_t is used consistently.
4712 Before, many places in the GnuTLS code used the old deprecated type
4713 names without the '_t' suffix.
4715 ** Build fixes for Guile code.
4716 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
4718 ** More documentation fixes.
4719 In particular, the section headings were modified for casing. By
4720 Ludovic Courtes <ludovic.courtes@laas.fr>.
4722 ** Updated Polish and Swedish translations.
4723 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
4724 <po@danielnylander.se>.
4726 ** API and ABI modifications:
4727 gnutls_sign_func: ADD, new type for sign callback.
4728 gnutls_sign_callback_set: ADD, new function to set sign callback.
4729 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
4730 gnutls_x509_privkey_sign_hash,
4731 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
4732 GNUTLS_E_APPLICATION_ERROR_MIN,
4733 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
4735 * Version 1.7.16 (released 2007-08-07)
4737 ** Fix sanity checks and return values in certificate selection.
4738 In some cases, GnuTLS omitted to report suitable error codes when no
4739 suitable certificate was found.
4741 ** Fix gnutls-cli starttls EOF on Mac OS X.
4742 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
4744 ** Documentation fixes.
4745 In particular, the section headings were modified for casing. By
4746 Ludovic Courtes <ludovic.courtes@laas.fr>.
4748 ** Update gnulib files.
4750 ** API and ABI modifications:
4751 No changes since last version.
4753 * Version 1.7.15 (released 2007-07-02)
4755 ** Fix self-tests key-id under mingw32.
4757 ** Test that the Guile header files are recent enough to work.
4758 Before we just tested that the command line tool 'guile' was recent
4759 enough, which may not be sufficient if you still have an old
4760 libguile.h header installed.
4762 ** Guile bindings are now installed under $prefix by default.
4763 Use --without-guile-site-dir to install it under $pkgdatadir/site/
4764 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
4765 Use --with-guile-site-dir=/your/own/path to specify the path manually.
4766 The default, --with-guile-site-dir, will install the Guile bindings
4767 under $datadir/guile/site. There is a new section 'Guile
4768 Preparations' in the manual that discuss these issues.
4770 ** Fix run-time library path ordering in linking the Guile bindings.
4772 ** Improved manual on downloading, installing, getting help, bug reports etc.
4773 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
4775 ** Add Malay message translations.
4776 Thanks to Sharuzzaman Ahmat Raslan <sharuzzaman@myrealbox.com>.
4778 ** API and ABI modifications:
4779 No changes since last version.
4781 * Version 1.7.14 (released 2007-06-26)
4783 ** Don't enable Guile bindings unless we have Guile 1.8 or later.
4784 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4786 ** Fix memory leak during DSA signature verification.
4787 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.

4795 Patch from Timo Schulz <twoaday@freakmail.de> and Ludovic Courtès
4796 <ludovic.courtes@laas.fr>.
4798 ** Fix off-by-one in TLS 1.2 handshake.
4799 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4801 ** Minor Guile binding self-test cleanup.
4802 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.

4807 No changes since last version.
4809 * Version 1.7.13 (released 2007-06-11)
4811 ** OpenCDK copy updated to version 0.6.3.
4813 ** Build fixes for GnuTLS Guile bindings.
4814 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4816 ** Build fix for GTK-DOC manual.
4818 ** Update gnulib files.
4820 ** API and ABI modifications:
4821 No changes since last version.
4823 * Version 1.7.12 (released 2007-06-08)
4825 ** Guile bindings for GnuTLS have been included.
4826 Contributed by Ludovic Courtès <ludovic.courtes@laas.fr>. There is a
4827 new chapter 'Guile Bindings' in the manual.
4829 ** Have PKCS8 parser return better error codes.
4830 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
4831 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
4832 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
4834 ** Fix mem leak for sessions with client authentication via certificates.
4835 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
4836 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
4839 Reported by Dennis Vshivkov <walrus@amur.ru>, see
4840 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333050>. Added
4841 self-test tests/parse_ca.c to test regressions.
4843 ** Fix build failures related to missing images in manual.
4844 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
4846 ** Update gnulib files.
4848 ** API and ABI modifications:
4849 No changes since last version.
4851 * Version 1.7.11 (released 2007-05-26)
4853 ** Include opencdk.h in the release.
4854 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
4856 ** API and ABI modifications:
4857 No changes since last version.
4859 * Version 1.7.10 (released 2007-05-25)
4861 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
4862 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
4864 ** Update of gnulib files.
4866 ** GnuTLS is now developed in GIT instead of CVS.
4867 See <http://repo.or.cz/w/gnutls.git> for a public repository.
4869 ** API and ABI modifications:
4870 gnutls_x509_crt_get_raw_issuer_dn: ADD.
4871 gnutls_x509_crt_get_raw_dn: ADD.
4873 * Version 1.7.9 (released 2007-05-12)
4875 ** X.509 certificates are preferred over OpenPGP keys.
4876 This is a change in the semantics of gnutls_set_default_priority.
4878 ** The included copy of OpenCDK has been updated to 0.6.1.
4879 There has been some API changes in OpenCDK, and the GnuTLS layer have
4880 been modified as well. Note that while there are API/ABI incompatible
4881 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
4882 its API/ABI have not changed. From this version on, GnuTLS requires
4883 OpenCDK 0.6.0 or later.
4885 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
4887 ** Change certtool's default serial number from 0 to a time-based value.
4889 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
4890 Before, we remove the parameters field, which resulted in a slightly
4891 different DER encoding which in turn caused signature verification
4892 failures of GnuTLS-generated RSA certificates in some other
4893 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
4894 you read, this may or may not be correct, but our new behaviour appear
4895 to be consistent with other widely used implementations.
4897 ** Fix mem leaks in gnutls_x509_crt_print.
4899 ** API and ABI modifications:
4900 No changes since last version.
4902 * Version 1.7.8 (released 2007-04-16)
4904 ** Added examples for the authorization extension.
4905 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
4907 ** The examples only use gnutls_set_default_priority().
4908 The exception is when DH_ANON is needed.
4910 ** Improve gnutls_set_default_priority() priorities.
4911 The new approach is for it to try and negotiate all secure and
4912 standard mechanisms available. Currently, DH_ANON ciphersuites and
4913 LZO compressions are not enabled by default, because they are,
4914 respectively, insecure and non-standardized. Note that TLS 1.2 will
4915 not be enabled by default in non-experimental release until it has
4916 been approved by the IETF.
4918 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
4919 This means that to get DH_ANON and LZO compression, you'll need to
4920 specify that manually using '--kx anon' or '--comp lzo'.
4922 ** Minor fixes to the human display format of X.509 certificates.
4924 ** New APIs to extract Distinguished Name's from X.509 certificates.
4925 Based on patch from Howard Chu <hyc@symas.com>.
4927 ** Improved library searching for opencdk.
4928 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
4929 The deprecated opencdk.m4 is no longer used.
4931 ** New APIs to list supported algorithms in the library.
4932 The APIs are gnutls_cipher_list, gnutls_mac_list,
4933 gnutls_compression_list, gnutls_protocol_list,
4934 gnutls_certificate_type_list, gnutls_kx_list, and
4935 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
4937 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
4939 ** New configure option --disable-tls-authorization to disable tls-authz.
4941 ** Fix prototype for `gnutls_psk_set_client_credentials'.
4942 The last parameter was renamed from 'flags' to 'format' and the type
4943 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
4944 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
4947 ** Fix allocation in gnutls_certificate_set_openpgp_key.
4948 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
4950 ** API and ABI modifications:
4951 gnutls_x509_dn_t: ADD.
4952 gnutls_x509_ava_st: ADD.
4953 gnutls_x509_crt_get_subject,
4954 gnutls_x509_crt_get_issuer: ADD.
4955 gnutls_x509_dn_get_rdn_ava: ADD.
4956 gnutls_cipher_list: ADD.
4957 gnutls_mac_list: ADD.
4958 gnutls_compression_list: ADD.
4959 gnutls_protocol_list: ADD.
4960 gnutls_certificate_type_list: ADD.
4961 gnutls_kx_list: ADD.
4962 gnutls_cipher_suite_info: ADD.
4964 * Version 1.7.7 (released 2007-02-22)
4966 ** Support for supplemental handshake messages and authorization data.
4967 Supplemental data is described in RFC 4680 and the authorization
4968 extensions in draft-housley-tls-authz-extns-07.
4970 ** Support for authorization data in gnutls-cli and gnutls-serv.
4971 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
4973 ** Fix for gnutls_x509_crt_check_hostname.
4974 Before it would have reported that the certificate matched a hostname
4975 when it did not have any dNSName or any CN field. Report and tiny
4976 patch from "Richard W.M. Jones" <rjones@redhat.com>.
4978 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
4979 Tests regressions of the bug, and several other features.
4981 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
4982 Before there were no support for iPAddress SAN's during comparison.
4984 ** New API to print information about CRL's.
4985 The function is gnutls_x509_crl_print.
4987 ** New API to extract signature value from CRL's.
4988 The function is gnutls_x509_crl_get_signature.
4990 ** Support for directoryName Subject Alternative Name's.
4991 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
4992 string in the provided buffer.
4994 ** Internal improvements to certtool.
4995 It uses gnutls_x509_crl_print to print CRL information. It uses some
4996 more gnulib modules to simplify error handling.
4998 ** API and ABI modifications:
4999 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
5000 gnutls_supplemental_data_format_type_t: ADD.
5001 gnutls_authz_data_format_type_t: ADD.
5002 gnutls_supplemental_get_name: ADD.
5003 gnutls_authz_recv_callback_func,
5004 gnutls_authz_send_callback_func: ADD, callback prototypes.
5005 gnutls_authz_enable: ADD.
5006 gnutls_authz_send_x509_attr_cert,
5007 gnutls_authz_send_saml_assertion,
5008 gnutls_authz_send_x509_attr_cert_url,
5009 gnutls_authz_send_saml_assertion_url: ADD.
5010 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
5011 gnutls_x509_crl_print: ADD.
5012 gnutls_x509_crl_get_signature: ADD.
5014 * Version 1.7.6 (released 2007-02-12)
5016 ** Support for 'otherName' Subject Alternative Names.
5017 The existing API gnutls_x509_crt_get_subject_alt_name may now return
5018 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
5019 To find out the otherName OID (necessary for proper parsing of the
5020 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
5021 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
5022 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
5023 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
5025 ** Certtool can print otherName SAN values for certificates.
5026 For known otherName OIDs (currently only id-on-xmppAddr as defined by
5027 RFC 3920), it will also print the name.
5029 ** Fix TLS 1.2 RSA signing in servers.
5030 Before it used the old-style MD5+SHA1 signature, but the TLS
5031 signatures should be normal PKCS#1 signatures. FYI, we use and
5032 require that DigestInfo parameters are present and NULL for TLS 1.2.
5034 ** Add APIs to access X.509 extensions sequentially.
5035 The existing APIs gnutls_x509_crt_get_extension_oid() and
5036 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
5037 inspect the extensions in the order defined by the certificate.
5039 ** Add API to extract signature value from X.509 certificates.
5040 The function is gnutls_x509_crt_get_signature.
5042 ** Fix crash when generating proxy certificates in batch mode.
5043 If you don't specify a proxy policy in batch mode, it will use
5046 ** Add API to print information about X.509 certificates.
5047 The function is gnutls_x509_crt_print.
5049 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
5050 One consequence of this is that the output syntax has changed
5051 slightly. Some more fields are printed.
5055 ** API and ABI modifications:
5056 gnutls_x509_crt_print: ADD
5057 gnutls_certificate_print_formats_t: ADD, new enum.
5058 gnutls_x509_crt_get_signature: ADD.
5059 gnutls_x509_crt_get_extension_data: ADD.
5060 gnutls_x509_crt_get_extension_info: ADD.
5061 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
5062 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
5063 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
5065 * Version 1.7.5 (released 2007-02-06)
5067 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
5070 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
5072 ** Fix --list output for gnutls-cli and gnutls-serv.
5073 Mention TLS1.2, SHA512 etc.
5075 ** Manual contains new section on setting up a test HTTP server.
5076 A server set up following those descriptions are available online via
5077 <http://www.gnutls.org/server.html>.
5079 ** Update of gnulib files.
5081 ** API and ABI modifications:
5082 No changes since last version.
5084 * Version 1.7.4 (released 2007-02-05)
5086 ** Support for RSA signing using SHA-256/384/512.
5087 A new self test "sha2" tries to build a long X.509 certificate chain
5088 testing all new hashes.
5090 ** The gnutls-serv tool now use static DH parameters if none are supplied.
5092 ** Discuss proxy certificates in the manual.
5094 ** Improve bibliographical citations in the manual.
5096 ** Update of gnulib files.
5098 ** Fix certtool template handling of pathLenConstraints.
5099 It now defaults to -1 instead of 0, which causes the field to be
5100 missing unless the template specify it.
5102 ** API and ABI modifications:
5105 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
5108 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
5109 GNUTLS_SIGN_RSA_SHA256,
5110 GNUTLS_SIGN_RSA_SHA384,
5111 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
5113 * Version 1.7.3 (released 2007-02-01)
5115 ** New option to certtool: --generate-proxy.
5116 This will generate a Proxy Certificate from an end entity certificate.
5117 Proxy Certificates are documented in RFC 3820. You will need to
5118 specify the proxy certificate's private key with --load-privkey, the
5119 user certificate with --load-certificate and the private key used to
5120 sign the new proxy certificate with --load-ca-privkey. Certtool will
5121 query for proxy path length and the policy language OID. Currently
5122 only OIDs that have an empty policy are supported (which includes the
5123 two OIDs defined by RFC 3820).
5125 ** Certtool --certificate-info now prints information for Proxy Certificates.
5126 Before the proxy extension was just printed as DER encoded data.
5128 ** New APIs to set proxy subject names and get/set proxy cert extension.
5130 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
5132 ** Added self-test to test for regressions of pathLenConstraint bug.
5133 Incidentally, this also test (some) other regressions or changes in
5134 the output from certtool --certificate-info.
5136 ** When certtool generates CA certificates, pressing enter on the path
5137 ** length constraint query will now remove the field.
5138 Before it set the path length constraint to 0, which is a rather poor
5141 ** Certtool now print times in UTC when printing certificate/CRL info.
5143 ** Add better fix to work around C++ compiler bug on Mac OS X.
5144 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
5146 ** Fix import of ASCII armored OpenPGP keys.
5147 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
5149 ** Update of gnulib files.
5151 ** API and ABI modifications:
5152 gnutls_x509_crt_set_proxy_dn: ADD.
5153 gnutls_x509_crt_set_proxy: ADD.
5154 gnutls_x509_crt_get_proxy: ADD.
5156 * Version 1.7.2 (released 2007-01-14)
5158 ** Certtool now print the value of the pathLenConstraints field for certs.
5160 ** Certtool now query for path length constraints when generating CA certs.
5161 For batch uses, the certtool configuration name is "path_len".
5162 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5164 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
5165 The new functions gnutls_x509_crt_get_basic_constraints and
5166 gnutls_x509_crt_set_basic_constraints provide a superset of the
5167 functionality in the old gnutls_x509_crt_get_ca_status and
5168 gnutls_x509_crt_set_ca_status (respectively), but the old functions
5169 will continue to be supported.
5171 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
5172 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
5173 OpenCDK release with this patch will be made soon, which should bump
5174 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
5176 ** Certtool --to-p12 can now store more than one certificate in the blob.
5177 Before it could only store one certificate, but now it will read and
5178 store as many certificate there are from the --load-certificate file.
5179 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5181 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
5182 In particular, the OpenPGP function variables are no longer part of
5183 the exported libgnutls interface, and no header files from
5184 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
5185 were never intended for non-internal purposes, and thus this does not
5186 imply a change in the external API/ABI.
5188 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
5189 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5191 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
5192 Before these parameters were set to make GnuTLS build under mingw32,
5193 however, they appear to no longer be necessary.
5195 ** A minor fix to the C++ library to make it build.
5196 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
5198 ** Update of gnulib files.
5200 ** API and ABI modifications:
5201 gnutls_x509_crt_get_basic_constraints: ADD.
5202 gnutls_x509_crt_set_basic_constraints: ADD.
5203 cdk_pubkey_to_sexp: ADD (in opencdk).
5204 cdk_seckey_to_sexp: ADD (in opencdk).
5206 * Version 1.7.1 (released 2006-12-28)
5208 ** TLS 1.2 server side fix.
5209 The Certificate Request sent did not contain the list of supported
5210 hashes field, thus violating the protocol. It will now contain an
5211 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5213 ** TLS 1.2 DSA signature verification fix.
5214 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5216 ** Fix the list of trusted CAs that server's send to clients.
5217 Before, the list contained issuer DN's instead of subject DN's of the
5218 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5220 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5221 Also added a self-test in tests/certificate_set_x509_crl.c to test the
5222 function. Reported by Max Kellermann <max@duempel.org>.
5224 ** Encode UID fields in DN's as DirectoryString.
5225 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5226 incorrect, it should have used DirectoryString. Now it will use
5227 DirectoryString for the UID field, but for backwards compatibility it
5228 will also accept IA5String UID's. Reported by Max Kellermann
5231 ** Improve out-of-sourcedir builds from CVS.
5232 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5234 ** Bootstrap tools changed.
5235 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
5236 building GnuTLS from CVS. Libtool 1.5.22 is used.
5238 ** Fixed a syntax error in lib/gnutls.asn.
5239 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
5241 ** Added German translation of GnuTLS messages.
5243 ** Update of gnulib files.
5245 ** API and ABI modifications:
5246 No changes since last version.
5248 * Version 1.7.0 (released 2006-11-29)
5250 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
5251 The details is that the protocol priority set by
5252 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
5253 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
5255 ** Preliminary support for TLS 1.2.
5256 The client has been successfully tested against
5257 https://www.mikestoolbox.org:4433/.
5259 ** Anonself test now print a lot of debugging info, including TLS version.
5261 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
5263 ** Update of gnulib files.
5265 ** API and ABI modifications:
5266 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
5268 *** Pulled up from stable 1.6.x branch:
5270 ** Fix ./configure failure with non-GCC compilers.
5271 This fixes the following error message:
5272 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5273 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5275 * Version 1.6.3 (released 2007-05-26)
5277 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
5278 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
5279 from the 1.7.x branch, see
5280 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
5282 ** Have PKCS8 parser return better error codes.
5283 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
5284 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
5285 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
5287 ** Fix mem leak for sessions with client authentication via certificates.
5288 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
5289 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
5291 ** Fix building of 'tlsia' self test.
5292 Earlier some gcc are known to build tlsia linking to
5293 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
5294 the build directory, even though command line parameters look OK.
5295 Changing order of some parameters fixes it.
5297 ** API and ABI modifications:
5298 gnutls_x509_crt_get_raw_issuer_dn: ADD.
5299 gnutls_x509_crt_get_raw_dn: ADD.
5301 * Version 1.6.2 (released 2007-04-18)
5303 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
5304 Before, we remove the parameters field, which resulted in a slightly
5305 different DER encoding which in turn caused signature verification
5306 failures of GnuTLS-generated RSA certificates in some other
5307 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
5308 you read, this may or may not be correct, but our new behaviour appear
5309 to be consistent with other widely used implementations.
5311 ** Regenerate the PKIX ASN.1 syntax tree.
5312 For some reason, after changing the ASN.1 type of ldap-UID in the last
5313 release, the generated C file built from the ASN.1 schema was not
5314 refreshed. This can cause problems when reading/writing UID
5315 components inside X.500 Distinguished Names. Reported by devel
5316 <dev001@pas-world.com>.
5318 ** Updated translations.
5320 ** API and ABI modifications:
5321 No changes since last version.
5323 * Version 1.6.1 (released 2006-12-28)
5325 ** Fix the list of trusted CAs that server's send to clients.
5326 Before, the list contained issuer DN's instead of subject DN's of the
5327 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5329 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5330 Reported by Max Kellermann <max@duempel.org>.
5332 ** Encode UID fields in DN's as DirectoryString.
5333 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5334 incorrect, it should have used DirectoryString. Now it will use
5335 DirectoryString for the UID field, but for backwards compatibility it
5336 will also accept IA5String UID's. Reported by Max Kellermann
5339 ** Fix ./configure failure with non-GCC compilers.
5340 This fixes the following error message:
5341 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5342 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5344 ** API and ABI modifications:
5345 No changes since last version.
5347 * Version 1.6.0 (released 2006-11-17)
5349 ** No changes since 1.5.5.
5350 The major changes compared to the 1.4.x branch are:
5352 *** A GnuTLS C++ library is part of the official distribution.
5353 Currently there are no examples or documentation, but hopefully this
5354 will change. See gnutlsxx.h for the API.
5356 *** Windows is a supported platform.
5357 There are, however, two know bugs. One is related to select() in
5358 command line tools (not, nota bene, in the library), the other is a
5359 problem with libgcrypt that causes delays. Help is needed to resolve
5360 those issues, so we feel we can't delay the release because of this.
5362 *** New APIs for custom push/pull function error reporting.
5363 The new APIs are gnutls_transport_set_errno and
5364 gnutls_transport_set_global_errno. See the release notes for version
5365 1.5.4 for more information.
5367 *** Self tests are run under valgrind, if available. See --disable-valgrind.
5369 * Version 1.5.5 (released 2006-11-16)
5371 ** Correctly bump shared library version after adding new APIs.
5372 This was forgotten in the last release.
5374 ** Fix unsigned vs signed problem in ex-x509-info.c example.
5375 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
5377 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
5379 ** Update of gnulib files.
5381 ** API and ABI modifications:
5382 No changes since last version.
5384 * Version 1.5.4 (released 2006-11-07)
5386 ** New API functions to set errno in push/pull functions.
5387 Under Windows, setting the errno variable in a push/pull replacement
5388 may end up setting the wrong errno variable, and GnuTLS send/recv
5389 functions become confused about the real errno returned from a failed
5390 push/pull function. Therefor, we have added two APIs to set the errno
5391 variable used by GnuTLS. The APIs can also help to keep things
5392 thread-safe, by avoiding potentially global variables. Typically,
5393 instead of setting errno in your push/pull function, you will call one
5394 of these functions. It is recommended to use
5395 gnutls_transport_set_errno, but if you don't have the session variable
5396 easily accessible in the push/pull replacement function, you can use
5397 gnutls_transport_set_global_errno. Suggested by Tim Kosse
5398 <tim.kosse@filezilla-project.org>.
5400 void gnutls_transport_set_errno (gnutls_session_t session, int err);
5401 void gnutls_transport_set_global_errno (int err);
5403 ** When calling `recv' or `send' Windows errors are handled properly.
5404 The Windows recv/send functions doesn't use errno, and GnuTLS now use
5405 WSAGetLastError to access the error condition instead.
5407 ** Several OpenPGP API fixes.
5408 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
5409 important fix is to change the return value of
5410 gnutls_openpgp_privkey_get_pk_algorithm and
5411 gnutls_openpgp_key_get_pk_algorithm from 'int' to
5412 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
5413 compatible with 'int').
5415 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5416 ** version, try to negotiate the highest version support by the GnuTLS server,
5417 ** instead of the lowest.
5418 Reported by <Pasi.Eronen@nokia.com>.
5420 ** Replace old constructs with use of gnulib modules.
5421 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
5422 the code. If the headers doesn't exist on the target system, gnulib
5423 will make sure its replacement header files are used instead.
5425 ** Fix SOVERSION computation for *.def files.
5426 This fixes build errors similar to "No rule to make target
5427 `libgnutls-`expr', needed by `all-am'." when building for Windows.
5429 ** gnutls_check-version uses strverscmp from gnulib.
5431 ** Update of gnulib files.
5433 ** API and ABI modifications:
5434 gnutls_transport_set_errno: ADD
5435 gnutls_transport_set_global_errno: ADD
5437 * Version 1.5.3 (released 2006-10-26)
5439 ** Add new self-test of RSA-MD5 signature chains.
5440 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
5441 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
5442 and is based on the work by Marc Stevens et al, see
5443 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
5445 ** Re-factor self tests.
5447 ** The include copy of Libtasn1 is updated to version 0.3.7.
5449 ** The included copy of OpenCDK is updated to version 0.5.11.
5451 ** Fix the filename of the *.def file on Windows after library version bump.
5453 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
5454 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
5455 gnulib modules. Earlier we could only use the LGPL'ed module from
5456 gnulib, because two gnulib directories in the same project didn't
5459 ** API and ABI modifications:
5460 No changes since last version.
5462 * Version 1.5.2 (released 2006-10-03)
5464 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
5465 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
5466 shared library version than this version, so you'll have to remove
5467 them and possibly relink your applications. The reason for this is
5468 that no API/ABI changes have been made since the 1.4.x branch, and
5469 that incrementing the shared library version was a mistake. Reported
5470 by Andreas Metzler <ametzler@downhill.at.eu.org>.
5472 ** Fix off-by-one error when computing length to malloc.
5473 The code is used by gnutls_openpgp_add_keyring_file and
5474 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
5475 <agl@imperialviolet.org>.
5477 ** Add version script for the GnuTLS C++ library.
5478 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5480 ** Fix the C++ compiler detection logic.
5481 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5483 ** Update of gnulib files.
5485 ** API and ABI modifications:
5486 No changes since last version.
5488 * Version 1.5.1 (released 2006-09-21)
5490 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5491 ** Crypto 06 rump session attack.
5492 In particular, we check that the digestAlgorithm.parameters field is
5493 missing or empty, to avoid that it can contain "garbage" that may be
5494 used to alter the numeric properties of the signature. See
5495 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
5496 not exactly the same as the problem we fix here). Reported by Yutaka
5497 OIWA <y.oiwa@aist.go.jp>.
5499 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
5500 up to date information.
5502 ** Add self test to test for above flaw.
5504 ** Fix gnutls-cli-debug regarding resume support detection.
5505 Earlier, if the session-id from the server had a length of 0, it would
5506 indicate that the server supports resumption, which isn't the case.
5507 Reported by Kataja Kai <kai.kataja@op.fi>.
5509 ** Fix building of examples on FreeBSD by including netinet/in.h.
5510 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
5512 ** Fix certtool bug that caused the private key to not be loaded when
5513 generating a certificate with --load-request, which in turn triggered
5514 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
5515 by Sascha Ziemann <sascha.ziemann@secunet.com>.
5517 ** gnutls-cli and gnutls-serv works on Windows.
5518 The problem was the select() call that doesn't work on file
5519 descriptors (stdin) on Windows. We borrowed some code from plibc to
5520 solve this. It appears to be somewhat unreliable though.
5522 ** Autoconf 2.60 is now used.
5524 ** API and ABI modifications:
5525 No changes since last version.
5527 * Version 1.5.0 (released 2006-08-13)
5529 ** Change SRP and Cert-Type extensions to match IANA registry.
5531 ** Fixed bug in OpenPGP authentication handshake.
5533 ** Improvements for building under MinGW.
5534 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
5535 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
5536 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
5537 at run-time from ws2_32.dll, and falls back on a simple replacement if
5538 it is not available. Builds the library with -mms-bitfields
5539 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
5540 create *.def files, which are installed.
5542 ** The examples now (conditionally) include config.h and link to gnulib.
5543 No other source changes were necessary, so the examples should
5544 continue to be possible to use stand-alone without any autoconf or
5547 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
5548 You may unconditionally disable it with --disable-cxx. See
5549 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
5552 ** Made command line tool '--version' behave according to GNU Standards.
5553 This enables 'make distcheck' to succeed.
5555 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5557 ** Make --without-included-libtasn1 work.
5558 Reported by Daniel Black <dragonheart@gentoo.org>.
5560 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5561 See http://www.gnu.org/software/gnutls/security.html regardging
5562 GNUTLS-SA-2006-2 for more up to date information. Reported by
5563 satyakumar <satyam_kkd@hyd.hellosoft.com>.
5565 ** API and ABI modifications:
5566 No changes since last version.
5568 * Version 1.4.5 (released 2006-11-06)
5570 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5571 ** version, try to negotiate the highest version support by the GnuTLS server,
5572 ** instead of the lowest.
5573 Reported by <Pasi.Eronen@nokia.com>.

5576 Reported by Adam Langley" <agl@imperialviolet.org>.
5578 ** API and ABI modifications:
5579 No changes since last version.
5581 * Version 1.4.4 (released 2006-09-12)
5583 ** Relax the test that caught signatures that exploit the variant of
5584 ** Bleichenbacher's Crypto 06 rump session attack on our
5585 ** verification logic flaw.
5586 In particular, we now permit the digestAlgorithm.parameters field to
5587 be present but empty, whereas in 1.4.3 we actually checked that the
5590 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
5591 The messages are only printed in debug mode, which is not recommended
5592 for normal use, and thus logging this situation cannot be abused as an
5593 oracle in typical recommended situations.
5595 ** API and ABI modifications:
5596 No changes since last version.
5598 * Version 1.4.3 (released 2006-09-08)
5600 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5601 ** Crypto 06 rump session attack.
5602 In particular, we check that the digestAlgorithm.parameters field is
5603 empty, to avoid that it can contain "garbage" that may be used to
5604 alter the numeric properties of the signature. See
5605 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is

5621 ** API and ABI modifications:
5622 No changes since last version.
5624 * Version 1.4.2 (released 2006-08-12)
5626 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5627 This can happen if you call gnutls_certificate_verify_peers2 and have
5628 a certain mix of local CA certificates and the peer send special
5629 certificates, that together trigger certain behaviour. It is not
5630 known at this point whether the crash can be triggered without the
5631 special local CA certificate, and thus turn this into a remote crash
5632 of clients that verify server certificates when they talk to a server
5633 with the special server certificate. See GNUTLS-SA-2006-2 on
5634 http://www.gnu.org/software/gnutls/security.html for more up to date
5635 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
5637 ** Change SRP and Cert-Type extensions to match IANA registry.
5639 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5641 ** Make --without-included-libtasn1 work.
5642 Reported by Daniel Black <dragonheart@gentoo.org>.
5644 ** API and ABI modifications:
5645 No changes since last version.
5647 * Version 1.4.1 (released 2006-06-14)
5649 ** Replaced inactive ifdefs to enable openpgp support in test programs.
5651 ** Fixed bug in OpenPGP authentication handshake.
5653 ** Fixed typographical in man pages.
5655 ** Build fixes of the manual.
5657 ** Added Swedish translation.

5660 No changes since last version.
5662 * Version 1.4.0 (released 2006-05-15)
5664 ** Remove GnuTLS 0.8.x compatibility functions.
5666 ** The libgcrypt RNG is initialized in gnutls_global_init().
5668 ** TLS/IA API changes from Emile van Bergen.
5669 A dummy credential structure is not needed now, if you wish to use the
5670 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
5673 ** The self-tests are now run under valgrind, if it is installed.
5675 ** Libtasn1 is updated to 0.3.4, and that version is now required.
5677 ** The command line tools now use getaddrinfo and support IPv6.
5679 ** API and ABI modifications:
5680 _gnutls_x509_get_raw_crt_activation_time,
5681 _gnutls_x509_get_raw_crt_expiration_time: Removed.
5682 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
5683 gnutls_ia_enable: Added.
5685 * Version 1.3.5 (released 2006-03-08)
5687 ** Error messages are now translated using GNU Gettext.
5689 ** The function gnutls_x509_crt_to_xml now return an internal error.
5690 This means that the code to convert X.509 certificates to XML format
5691 does not work any more. The reason is that the function called
5692 libtasn1 internal functions. It seems unclean for libtasn1 to export
5693 the APIs needed here. Instead it would be better to implement XML
5694 support inside libtasn1 properly. If you need this functionality
5695 strongly, please consider looking into implementing this suggested
5696 approach instead. As a workaround, you may also modify lib/x509/xml.c
5697 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
5699 ** Libraries are now built with libtool's -no-undefined.
5700 This helps producing libraries for Windows using mingw32.
5702 ** Doc fixes to explain that gnutls_record_send can block.
5704 ** Libtasn1 0.3.1 or later is now required.
5705 The include copy has been updated too.
5707 ** gnutls-cli can now recognize services and port numbers with the -p option.
5709 ** API and ABI modifications:
5710 No changes since last version.
5712 * Version 1.3.4 (released 2006-02-09)
5714 ** Fix read of out bounds bug in DER parser.
5715 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
5716 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
5717 previous bug fix. The included libtasn1 version in GnuTLS has been
5720 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5721 longer invalidate a session if the underlying send fails, but it will
5722 prevent future writes. That is to allow reading the already received data.
5723 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5725 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
5726 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5727 more than one certificates were added. Report and patch by Max Kellermann.
5729 ** Fix build problems of OpenCDK on AIX.
5730 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
5732 ** API and ABI modifications:
5733 No changes since last version.
5735 * Version 1.3.3 (released 2006-01-12)
5737 ** New API to access the TLS master secret.
5738 When possible, you should use the TLS PRF functions instead.
5739 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5741 ** Improved handling when multiple libraries use GnuTLS at the same time.
5742 Now gnutls_global_init() can be called multiple times, and
5743 gnutls_global_deinit() will only deallocate the structure when it has
5744 been called as many times as gnutls_global_init() was called.
5746 ** Added a self test of TLS resume functionality.
5748 ** Fix crash in TLS resume code, caused by TLS/IA changes.
5750 ** Documentation fixes about thread unsafety, prompted by
5751 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
5752 In particular, gnutls_global_init() and gnutls_global_deinit() are not
5753 thread safe. Careful callers may want to protect the call using a
5754 mutex. The problem could also be ignored, which would cause a memory
5755 leak under rare conditions when two threads invoke the function
5756 roughly at the same time.
5758 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
5760 ** The code was indented again, including the external header files.
5762 ** API and ABI modifications:
5763 New functions to retrieve the master secret value:
5764 gnutls_session_get_master_secret
5766 Add a 'const' keyword to existing API:
5767 gnutls_x509_crq_get_challenge_password
5769 * Version 1.3.2 (released 2005-12-15)
5771 ** GnuTLS now support TLS Inner application (TLS/IA).
5772 This is per draft-funk-tls-inner-application-extension-01. This
5773 functionality is added to libgnutls-extra, so it is licensed under the
5774 GNU General Public License.
5776 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
5777 The PRF is used by some protocols building on TLS, such as EAP-PEAP
5778 and EAP-TTLS. One function to access the raw PRF and one to access
5779 the PRF seeded with the client/server random fields are provided.
5780 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5782 ** New APIs to acceess the client and server random fields in a session.
5783 These fields can be useful by protocols using TLS. Note that these
5784 fields are typically used as input to the TLS PRF, and if this is your
5785 intended use, you should use the TLS PRF API that use the
5786 client/server random field directly. Suggested by Jouni Malinen
5787 <jkmaline@cc.hut.fi>.
5789 ** Internal type cleanups.
5790 The uint8, uint16, uint32 types have been replaced by uint8_t,
5791 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
5792 correct types on platforms that lack them. The uint type have been
5793 replaced by unsigned.
5795 ** API and ABI modifications:
5796 New functions to invoke the TLS Pseudo-Random-Function (PRF):
5800 New functions to retrieve the session's client and server random values:
5801 gnutls_session_get_server_random
5802 gnutls_session_get_client_random
5804 New function, to perform TLS/IA handshake:
5807 New function to decide whether to do a TLS/IA handshake:
5808 gnutls_ia_handshake_p
5810 New functions to allocate a TLS/IA credential:
5811 gnutls_ia_allocate_client_credentials
5812 gnutls_ia_free_client_credentials
5813 gnutls_ia_allocate_server_credentials
5814 gnutls_ia_free_server_credentials
5816 New functions to handle the AVP callback:
5817 gnutls_ia_set_client_avp_function
5818 gnutls_ia_set_client_avp_ptr
5819 gnutls_ia_get_client_avp_ptr
5820 gnutls_ia_set_server_avp_function
5821 gnutls_ia_set_server_avp_ptr
5822 gnutls_ia_get_server_avp_ptr
5824 New functions, to toggle TLS/IA application phases:
5825 gnutls_ia_require_inner_phase
5827 New function to mix session keys with inner secret:
5828 gnutls_ia_permute_inner_secret
5830 Low-level API (used internally by gnutls_ia_handshake):
5831 gnutls_ia_endphase_send
5835 New functions that can be used after successful TLS/IA negotiation:
5836 gnutls_ia_generate_challenge
5837 gnutls_ia_extract_inner_secret
5839 Enum type with TLS/IA modes:
5842 Enum type with TLS/IA packet types:
5845 Enum values for TLS/IA alerts:
5846 GNUTLS_A_INNER_APPLICATION_FAILURE
5847 GNUTLS_A_INNER_APPLICATION_VERIFICATION
5849 New error codes, to signal when an application phase has finished:
5850 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
5851 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
5853 New error code to signal TLS/IA verify failure:
5854 GNUTLS_E_IA_VERIFY_FAILED
5856 * Version 1.3.1 (released 2005-12-08)
5858 ** Support for DHE-PSK cipher suites has been added.
5859 This method offers perfect forward secrecy.
5861 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5862 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5864 ** Corrected a bug in certtool for 64 bit machines. Reported
5865 by Max Kellermann <max@duempel.org>.
5867 ** New function to set a X.509 private key and certificate pairs, and/or
5868 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
5869 <emile@e-advies.nl>.
5871 The integrity of the PKCS#12 file is protected through a password
5872 based MAC; public-key based signatures for integrity protection are
5873 not supported. PKCS#12 bags may be encrypted using password derived
5874 symmetric keys, public-key based encryption is not supported. The
5875 PKCS#8 keys may be encrypted using passwords. The API use the same
5876 password for all operations. We believe that any more flexibility
5877 create too much complexity that would hurt overall security, but may
5878 add more PKCS#12 related APIs if real-world experience indicate
5881 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
5882 reported by Emile van Bergen <emile@e-advies.nl>.
5883 This will enable "certtool -k -8" to parse those keys.
5885 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
5886 Use "certtool -p -8" and press press enter at the prompt. Earlier,
5887 certtool would have encrypted the key using an empty password.
5889 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
5890 Earlier it would have prompted the user for it, even if --password was
5893 ** Added self test of PKCS#8 parsing.
5894 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
5895 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
5898 ** API and ABI modifications:
5899 New function to set X.509 credentials from a PKCS#12 file:
5900 gnutls_certificate_set_x509_simple_pkcs12_file
5902 New gnutls_kx_algorithm_t enum type:
5905 New API to return session data (basically same as gnutls_session_get_data):
5906 gnutls_session_get_data2
5908 New API to set PSK Diffie-Hellman parameters:
5909 gnutls_psk_set_server_dh_params
5911 * Version 1.3.0 (2005-11-15)
5913 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
5914 This add several new APIs, see below. Read the updated manual for
5915 more information. A new self test "pskself" has been added, that will
5916 test this functionality.
5918 ** The session resumption data are now system independent.
5920 ** The code has been re-indented to conform to the GNU coding style.
5922 ** Removed the RIPEMD ciphersuites.
5924 ** Added a discussion of the internals of gnutls in manual.
5926 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
5928 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
5930 ** Make sure config.h is included first in a few files, from Albert Chin.
5932 ** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
5934 ** Don't install SRP programs and man pages if --disable-srp-authentication,
5937 ** API and ABI modifications:
5938 New gnutls_kx_algorithm_t key exchange type: GNUTLS_KX_PSK
5940 New gnutls_credentials_type_t credential type:
5943 New credential types:
5944 gnutls_psk_server_credentials_t
5945 gnutls_psk_client_credentials_t
5947 New functions to allocate PSK credentials:
5948 gnutls_psk_allocate_client_credentials
5949 gnutls_psk_free_client_credentials
5950 gnutls_psk_free_server_credentials
5951 gnutls_psk_allocate_server_credentials
5953 New enum type for PSK key flags:
5954 gnutls_psk_key_flags
5956 New function prototypes for credential callback:
5957 gnutls_psk_client_credentials_function
5958 gnutls_psk_server_credentials_function
5960 New function to set PSK username and key:
5961 gnutls_psk_set_client_credentials
5963 New function to set PSK passwd file:
5964 gnutls_psk_set_server_credentials_file
5966 New function to extract PSK user in server:
5967 gnutls_psk_server_get_username
5969 New functions to set PSK callback:
5970 gnutls_psk_set_server_credentials_function
5971 gnutls_psk_set_client_credentials_function
5973 Use size_t instead of int for output size parameter:
5974 gnutls_srp_base64_encode
5975 gnutls_srp_base64_decode
5977 * Version 1.2.11 (2006-05-11)
5978 - The function gnutls_x509_crt_to_xml is not supported any more, and
5979 return an internal error. The reason is that the function called
5980 internal libtasn1 functions which are no longer exported from
5982 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
5983 - Updated gnulib compatibility files.
5984 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
5985 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
5986 - API and ABI modifications:
5987 No changes since last version.
5989 * Version 1.2.10 (2006-02-09)
5990 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
5991 <admin@gleg.net>, and debugging help from Protover SSL.
5992 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
5993 The included version has been updated too.
5994 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5995 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5996 - Corrected a bug in certtool for 64 bit machines. Reported
5997 by Max Kellermann <max@duempel.org>.
5998 - Corrected bugs in gnutls_certificate_set_x509_crl() and
5999 gnutls_certificate_set_x509_trust(), that caused memory corruption if
6000 more than one certificates were added. Report and patch by Max Kellermann.
6001 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
6002 longer invalidate a session if the underlying send fails, but it will
6003 prevent future writes. That is to allow reading the already received data.
6004 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
6006 * Version 1.2.9 (2005-11-07)
6007 - Documentation was updated and improved.
6008 - RSA-MD2 is now supported for verifying digital signatures.
6009 - Due to cryptographic advances, verifying untrusted X.509
6010 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
6011 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
6012 applications that must remain interoperable, you can use the
6013 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
6014 flags when verifying certificates. Naturally, this is not
6015 recommended default behaviour for applications. To enable the
6016 broken algorithms, call gnutls_certificate_set_verify_flags with the
6017 proper flag, to change the verification mode used by
6018 gnutls_certificate_verify_peers2.
6019 - Make it possible to send empty data through gnutls_record_send,
6020 to align with the send(2) API.
6021 - Some changes in the certificate receiving part of handshake to prevent
6022 some possible errors with non-blocking servers.
6023 - Added numeric version symbols to permit simple CPP-based feature
6024 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
6025 - The (experimental) low-level crypto alternative to libgcrypt used
6026 earlier (Nettle) has been replaced with crypto code from gnulib.
6027 This leads to easier re-use of these components in other projects,
6028 leading to more review and simpler maintenance. The new configure
6029 parameter --with-builtin-crypto replace the old --with-nettle, and
6030 must be used if you wish to enable this functionality. See README
6031 under "Experimental" for more information. Internally, GnuTLS has
6032 been updated to use the new "Generic Crypto" API in gl/gc.h. The
6033 API is similar to the old crypto/gc.h, because the gnulib code were
6034 based on GnuTLS's gc.h.
6035 - Fix compiler warning in the "anonself" self test.
6036 - API and ABI modifications:
6037 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
6038 This doesn't reflect a change in behaviour,
6039 so we don't break backwards compatibility.
6040 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
6041 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
6042 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
6043 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
6045 gnutls_x509_crt_list_verify,
6046 gnutls_x509_crt_verify, or
6047 gnutls_certificate_set_verify_flags.
6048 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
6049 used when broken signature algorithms
6050 is used (currently RSA-MD2/MD5).
6051 LIBGNUTLS_VERSION_MAJOR,
6052 LIBGNUTLS_VERSION_MINOR,
6053 LIBGNUTLS_VERSION_PATCH,
6054 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
6055 version number, can be used for feature existence
6058 * Version 1.2.8 (2005-10-07)
6059 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
6060 - Don't install the auxilliary libexamples library used by the
6061 examples in doc/examples/ on "make install", report and tiny patch
6062 from Thomas Klausner <tk@giga.or.at>.
6063 - If you pass a X.509 CA or PGP trust database to the command line
6064 tool, it will now abort the connection if the server certificate
6065 validation fails. Use the parameter --insecure to continue even
6066 after certificate validation failures. Inspired from discussion
6067 with Alexander Kotelnikov <sacha@myxomop.com>.
6068 - The test for socklen_t has been moved to gnulib.
6069 - Link failures for duplicate or missing "program_name" symbol has been fixed,
6070 patch from Martin Lambers <marlam@marlam.de>.
6071 - The command line tool and the examples no longer uses mmap or bzero,
6072 to make them more portable, patch from Martin Lambers
6074 - Made the PKCS #12 API handle null passwords. Based on patch by
6075 Anton Altaparmakov <aia21@cam.ac.uk>.
6076 - The GTK-DOC manual should build with current released tools.
6077 (But a copy of the output is included, so the tools are not required.)
6078 - The inet_ntop function is now used through gnulib.
6079 - API and ABI modifications:
6080 No changes since last version.
6082 * Version 1.2.7 (2005-09-09)
6083 - The GnuTLS and GnuTLS-extra libraries are now built with versioned symbols.
6084 - Certtool now complains when reading out-of-range X.509 serial
6085 numbers, suggested by Fran <e_agf@yahoo.es>.
6086 - Certtool now uses the readline library (when available) when reading
6087 X.509 serial numbers.
6088 - Fixed build problems in getpass on uClibc and Mingw32 platforms.
6089 - Fixed compile warning regarding socklen_t on Mingw32, reported by
6090 Martin Lambers <marlam@marlam.de>.
6091 - Fixed examples in doc/examples/, suggested by Fran <e_agf@yahoo.es>.
6092 - Gnulib is now used for the core library, enabling future code cleanups.
6093 - The gnutls-cli tool now use gnutls_certificate_verify_peers2,
6094 suggested by Daniel Stenberg <daniel@haxx.se>.
6095 - Doc fixes for gnutls_transport_set_push and gnutls_transport_set_pull.
6096 - Minilibtasn1 is now 0.2.17 (removed optional use of C99 macros).
6097 - Disable zlib support if zlib.h is not present.
6098 - A number of internal cleanups.
6099 - API and ABI modifications:
6100 No changes since last version.
6102 * Version 1.2.6 (2005-07-16)
6103 - MiniLZO updated to version 2.01 and moved to separate directory.
6104 - Collision between system LZO header files and MiniLZO header file
6105 fixed, reported by Matthias Urlichs <smurf@smurf.noris.de>.
6106 - Will now test for liblzo functionality in liblzo2 too, reported by
6107 Thomas Klausner <tk@giga.or.at>.
6108 - Minilibtasn1 is now 0.2.14 (no code changes).
6109 - Some code changes to avoid GTK-DOC warnings.
6110 - API and ABI modifications:
6111 No changes since last version.
6113 * Version 1.2.5 (2005-07-03)
6114 - More builddir != srcdir fixes, reported by Mike Castle
6115 <dalgoda@ix.netcom.com>.
6116 - Fixed off-by-one bug in the size parameter of gnutls_x509_crt_get*_dn,
6117 reported by Adam Langley <alangley@gmail.com>.
6118 - Corrected some stuff in minilzo detection. Pointed out by
6120 - MiniLZO updated to version 2.00.
6121 - gnutls_x509_crt_list_import now accept a DER formatted CRL.
6122 - API and ABI modifications:
6123 No changes since last version.
6125 * Version 1.2.4 (2005-05-28)
6126 - Corrected some bugs that could affect 64 bit systems.
6127 - Some corrections in the header files to include the prototype
6128 of memmem properly (affected 64 bit systems). Report and patch
6129 by Yoann Vandoorselaere <yoann@prelude-ids.org>.
6130 - Introduced the --fix-key option to certtool, which can be used to
6131 regenerate the (optional) parameters in a private key. It should
6132 be used together with --key-info.
6133 - Corrected a bug in certificate chain verification that could lead
6134 to marking a trusted chain as non trusted, if the last certificate in
6135 the chain was a self signed one.
6136 - Gnulib portability files were updated.
6137 - License were updated to reflect new FSF address.
6138 - API and ABI modifications:
6139 No changes since last version.
6141 * Version 1.2.3 (2005-04-28)
6142 - Corrected bug in record packet parsing that could lead
6143 to a denial of service attack.
6144 - Corrected bug in RSA key export. Previously exported keys
6145 can be fixed using certtool. Use certtool -k <infile >outfile
6146 - API and ABI modifications:
6147 gnutls_x509_privkey_fix(): Add.
6149 * Version 1.2.2 (2005-04-25)
6150 - gnutls_error_to_alert() now considers
6151 GNUTLS_E_UNEXPECTED_HANDSHAKE_PACKET.
6152 - Fixed error in session resuming that could cause a crash in a session.
6153 - Fixed pkcs12 friendly name and local key identifier decoding.
6154 - Internal cleanups, removed duplicate typedef/struct definitions,
6155 and made source code include external include file, to check
6156 function prototypes during compile time.
6157 - API and ABI modifications:
6158 No changes since last version. At least not intentional, but due
6159 to the include header changes, there may be inadvertant changes,
6160 please let us know if you find any.
6162 * Version 1.2.1 (2005-04-04)
6163 - gnutls_bye() will no longer fail when RDWR is used and application
6164 data are available for reading.
6165 - Added more strict checks for the SRP parameters (g,n), when they
6166 are not in the included list.
6167 - Added warning to certtool when MD5 is being used for digital
6169 - Optimizations ("-O2 -finline-functions") are not enabled by default,
6170 instead the standard autoconf defaults are used. Use `./configure
6171 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
