6 * Version 2.9.3 (unreleased)
8 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
9 The new APIs are gnutls_session_ticket_enable_client,
10 gnutls_session_ticket_enable_server, and
11 gnutls_session_ticket_key_generate.
13 ** gnutls-cli, gnutls-serv: New parameter --noticket to disable TLS tickets.
15 ** API and ABI modifications:
16 gnutls_session_ticket_key_generate: ADDED.
17 gnutls_session_ticket_enable_client: ADDED.
18 gnutls_session_ticket_enable_server: ADDED.
20 * Version 2.9.2 (released 2009-08-14)
22 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
23 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
24 into 1) not printing the entire CN/SAN field value when printing a
25 certificate and 2) cause incorrect positive matches when matching a
26 hostname against a certificate. Some CAs apparently have poor
27 checking of CN/SAN values and issue these (arguable invalid)
28 certificates. Combined, this can be used by attackers to become a
29 MITM on server-authenticated TLS sessions. The problem is mitigated
30 since attackers needs to get one certificate per site they want to
31 attack, and the attacker reveals his tracks by applying for a
32 certificate at the CA. It does not apply to client authenticated TLS
33 sessions. Research presented independently by Dan Kaminsky and Moxie
34 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
35 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
37 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
38 The function may fail incorrectly when an earlier certificate was
39 imported to the same gnutls_x509_crt_t structure.
41 ** minitasn1: Internal copy updated to libtasn1 v2.3.
43 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
44 Before it always returned false. Reported by Peter Hendrickson
46 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3668>.
48 ** libgnutls: Fix off-by-one size computation error in unknown DN printing.
49 The error resulted in truncated strings when printing unknown OIDs in
50 X.509 certificate DNs. Reported by Tim Kosse
51 <tim.kosse@filezilla-project.org> in
52 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3651>.
54 ** libgnutls: Fix PKCS#12 decryption from password.
55 The encryption key derived from the password was incorrect for (on
56 average) 1 in every 128 input for random inputs. Reported by "Kukosa,
57 Tomas" <tomas.kukosa@siemens-enterprise.com> in
58 <http://permalink.gmane.org/gmane.network.gnutls.general/1663>.
60 ** libgnutls: Return correct bit lengths of some MPIs.
61 gnutls_dh_get_prime_bits, gnutls_rsa_export_get_modulus_bits, and
62 gnutls_dh_get_peers_public_bits. Before the reported value was
63 overestimated. Reported by Peter Hendrickson <pdh@wiredyne.com> in
64 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3607>.
66 ** libgnutls: Avoid internal error when invoked after GNUTLS_E_AGAIN.
67 Report and patch by Tim Kosse <tim.kosse@filezilla-project.org> in
68 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3671>
70 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3670>.
72 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
73 Before we required that the runtime library used the same (or more
74 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
75 that the runtime usage is above the minimum required. Reported by
76 Marco d'Itri <md@linux.it> via Andreas Metzler
77 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.
79 ** tests: Added new self-test pkcs12_s2k_pem to detect MPI bit length error.
81 ** tests: Improved test vectors in self-test pkcs12_s2k.
83 ** tests: Added new self-test dn2 to detect off-by-one size error.

110 No changes since last version.
112 * Version 2.8.3 (released 2009-08-13)
114 ** libgnutls: Fix patch for NUL in CN/SAN in last release.
115 Code intended to be removed would lead to an read-out-bound error in
116 some situations. Reported by Tomas Hoger <thoger@redhat.com>. A CVE
117 code have been allocated for the vulnerability: [CVE-2009-2730].
119 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
120 The function may fail incorrectly when an earlier certificate was
121 imported to the same gnutls_x509_crt_t structure.
123 ** libgnutls-extra, libgnutls-openssl: Fix MinGW cross-compiling build error.
125 ** tests: Made self-test mini-eagain take less time.

308 No offically supported interfaces have been modified or removed. The
309 library should be completely backwards compatible on both the source
312 The shared library no longer exports some symbols that have never been
313 officially supported, i.e., not mentioned in any of the header files.
319 Normally when symbols are removed, the shared library version has to
320 be incremented. This leads to a significant cost for everyone using
321 the library. Because none of the above symbols have ever been
322 intended for use by well-behaved applications, we decided that the it
323 would be better for those applications to pay the price rather than
324 incurring problems on the majority of applications.
326 If it turns out that applications have been using unofficial
327 interfaces, we will need to release a follow-on release on the v2.8
328 branch to exports additional interfaces. However, initial testing
329 suggests that few if any applications have been using any of the
332 Although not a new change compared to 2.6.x, we'd like to remind you
333 interfaces have been modified so that X.509 chain verification now
334 also checks activation/expiration times on certificates. The affected
337 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
338 gnutls_certificate_verify_peers: Likewise.
339 gnutls_certificate_verify_peers2: Likewise.
340 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
341 GNUTLS_CERT_EXPIRED: ADDED.
342 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
344 This change in behaviour was made during the GnuTLS 2.6.x cycle, and
345 we gave our rationale for it in earlier release notes.
347 The following symbols have been added to the library:
349 gnutls_certificate_set_x509_simple_pkcs12_mem: ADDED
350 gnutls_x509_crl_get_authority_key_id: ADDED

509 Merged from stable branch. Reported by Romain Francoise
510 <romain@orebokech.com>. This changes the semantics of
511 gnutls_x509_crt_list_verify, which in turn is used by
512 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
513 We add two new gnutls_certificate_status_t codes for reporting the new
514 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
515 We also add a new gnutls_certificate_verify_flags flag,
516 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
517 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
519 ** lib: Linker version scripts reduces number of exported symbols.
520 The linker version script now lists all exported ABIs explicitly, to
521 avoid accidentally exporting unintended functions. Compared to
522 before, most symbols beginning with _gnutls* are no longer exported.
523 These functions have never been intended for use by applications, and
524 there were no prototypes for these function in the public header
525 files. Thus we believe it is possible to do this without incrementing
526 the library ABI version which normally has to be done when removing an
529 ** lib: Limit exported symbols on systems without LD linker scripts.
530 Before all symbols were exported. Now we limit the exported symbols
531 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
532 _gnutls*. This is a superset of the actual supported ABI, but still
533 an improvement compared to before. This is implemented using Libtool
534 -export-symbols-regex. It is more portable than linker version
537 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
538 This should have been done in the last release.
540 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
541 Reported by Peter Hendrickson <pdh@wiredyne.com> in
542 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
544 ** doc: Improved sections for the info manual.
545 We now follow the advice given by the texinfo manual on which
546 directory categories to use. In particular, libgnutls moved from the
547 'GNU Libraries' section to the 'Software libraries' and the command
548 line tools moved from 'Network Applications' to 'System
551 ** API and ABI modifications:
552 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
553 gnutls_certificate_verify_peers: Likewise.
554 gnutls_certificate_verify_peers2: Likewise.
555 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
556 GNUTLS_CERT_EXPIRED: ADDED.
557 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
559 * Version 2.7.7 (released 2009-04-20)
561 ** libgnutls: Applied patch by Cedric Bail to add functions
562 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
564 ** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.
565 Reported by Andreas Metzler <ametzler@downhill.at.eu.org> in
566 <http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3467>.
568 ** minitasn1: Internal copy updated to libtasn1 v1.8.
569 GnuTLS is also internally ready to be used with libtasn1 v2.0.
571 ** doc: Fix build failure of errcodes/printlist.
572 Reported by Roman Bogorodskiy <novel@FreeBSD.org> in
573 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3435>.
575 ** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
576 It is currently only used by the core library. This will enable a new
577 domain 'gnutls' for translations of the command line tools.
579 ** Corrected possible memory corruption on signature verification failure.
580 Reported by Miroslav Kratochvil <exa.exa@gmail.com>
582 ** API and ABI modifications:
583 gnutls_x509_crt_verify_hash: ADDED
584 gnutls_x509_crt_get_verify_algorithm: ADDED
586 * Version 2.7.6 (released 2009-02-27)
588 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
589 This applies both to generating certificates and certificate requests.
591 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
593 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
594 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
595 be used for chain verification.
597 ** gnutls-serv: No longer disable MAC padding by default.
598 Use --priority NORMAL:%COMPAT to disable MAC padding again.
600 ** gnutls-cli: Certificate information output format changed.
601 The tool now uses libgnutls' functions to print certificate
602 information. This avoids code duplication.
604 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
605 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
606 They can be used to override the default certificate chain validation
609 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
610 specify the client hello message record version. Used to overcome buggy
611 TLS servers. Report by Martin von Gagern.
613 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
615 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
617 ** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
619 ** API and ABI modifications:
620 No changes since last version.
622 * Version 2.7.5 (released 2009-02-06)
624 ** libgnutls: Accept chains where intermediary certs are trusted.
625 Before GnuTLS needed to validate the entire chain back to a
626 self-signed certificate. GnuTLS will now stop looking when it has
627 found an intermediary trusted certificate. The new behaviour is
628 useful when chains, for example, contains a top-level CA, an
629 intermediary CA signed using RSA-MD5, and an end-entity certificate.
630 To avoid chain validation errors due to the RSA-MD5 cert, you can
631 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
632 The signature on trusted certificates are not checked, so the chain
633 has a chance to validate correctly. Reported by "Douglas E. Engert"
634 <deengert@anl.gov> in
635 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
637 ** libgnutls: result_size in gnutls_hex_encode now holds
638 the size of the result. Report by John Brooks <special@dereferenced.net>.
640 ** libgnutls: gnutls_handshake when sending client hello during a
641 rehandshake, will not offer a version number larger than the current.
642 Reported by Tristan Hill <stan@saticed.me.uk>.
644 ** libgnutls: Permit V1 Certificate Authorities properly.
645 Before they were mistakenly rejected even though
646 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
647 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
648 "Douglas E. Engert" <deengert@anl.gov> in
649 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
651 ** API and ABI modifications:
652 No changes since last version.
654 * Version 2.7.4 (released 2009-01-07)
656 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
657 This is a bugfix -- the previous attempt to do this from internal x509
658 certificate verification procedures did not return the correct value
659 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
660 <dkg@fifthhorseman.net> in
661 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
662 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
663 Gillmor <dkg@fifthhorseman.net>.
665 ** libgnutls: New interface to get key id for certificate requests.
666 Patch from David MarÃn Carreño <davefx@gmail.com> in
667 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
669 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
671 ** certtool: --verify-chain now prints results of using library verification.
672 Earlier, certtool --verify-chain used its own validation algorithm
673 which wasn't guaranteed to give the same result as the libgnutls
674 internal validation algorithm. Now this command print a new final
675 line with header 'Chain verification output:' that contains the result
676 from using the internal verification algorithm on the same chain.
678 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
680 ** API and ABI modifications:
681 gnutls_x509_crq_get_key_id: ADDED.
683 * Version 2.7.3 (released 2008-12-10)
685 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
686 Reported by Michael Kiefer <Michael-Kiefer@web.de> in

688 Andreas Metzler <ametzler@downhill.at.eu.org> in
689 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
691 ** libgnutls: Libgcrypt initialization changed.
692 If libgcrypt has not already been initialized, GnuTLS will now
693 initialize libgcrypt with disabled secure memory. Initialize
694 libgcrypt explicitly in your application if you want to enable secure
695 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
696 allocation functions, which doesn't use secure memory, so there is no
697 real change in behaviour.
699 ** libgnutls: Fix memory leak in PSK authentication.
700 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
701 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
703 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
705 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
706 It needs to be invoked before libgcrypt is initialized.
708 ** gnutls-cli: Return non-zero exit code on error conditions.
710 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
712 ** tests: Added chainverify self-test that tests X.509 chain verifications.
714 ** API and ABI modifications:
715 No changes since last version.
717 * Version 2.7.2 (released 2008-11-18)
719 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
720 The flaw makes it possible for man in the middle attackers (i.e.,
721 active attackers) to assume any name and trick GNU TLS clients into
722 trusting that name. Thanks for report and analysis from Martin von
723 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
725 Any updates with more details about this vulnerability will be added
726 to <http://www.gnu.org/software/gnutls/security.html>

729 The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
730 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
731 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
732 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
733 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
734 work but are deprecated.
736 ** certtool: allow setting arbitrary key purpose object identifiers.

854 ** libgnutls: Corrected double free on signature verification failure.
855 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
856 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
858 ** libgnutls: Fix DSA key generation.
859 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
860 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
861 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
863 ** libgnutls: Check expiration/activation time on untrusted certificates.
864 Reported by Romain Francoise <romain@orebokech.com>. Before the
865 library did not check activation/expiration times on certificates, and
866 was documented as not doing so. We have realized that many
867 applications that use libgnutls, including gnutls-cli, fail to perform
868 proper checks. Implementing similar logic in all applications leads
869 to code duplication. Hence, we decided to check whether the current
870 time (as reported by the time function) is within the
871 activation/expiration period of certificates when verifying untrusted
874 This changes the semantics of gnutls_x509_crt_list_verify, which in
875 turn is used by gnutls_certificate_verify_peers and
876 gnutls_certificate_verify_peers2. We add two new
877 gnutls_certificate_status_t codes for reporting the new error
878 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
879 add a new gnutls_certificate_verify_flags flag,
880 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new

903 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
904 specify the client hello message record version. Used to overcome buggy
905 TLS servers. Report by Martin von Gagern.
907 ** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
908 Libtasn1 0.3.4 or later is required. This is to align with the
909 upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.

912 No changes since last version.
914 * Version 2.6.4 (released 2009-02-06)
916 ** libgnutls: Accept chains where intermediary certs are trusted.
917 Before GnuTLS needed to validate the entire chain back to a
918 self-signed certificate. GnuTLS will now stop looking when it has
919 found an intermediary trusted certificate. The new behaviour is
920 useful when chains, for example, contains a top-level CA, an
921 intermediary CA signed using RSA-MD5, and an end-entity certificate.
922 To avoid chain validation errors due to the RSA-MD5 cert, you can
923 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
924 The signature on trusted certificates are not checked, so the chain
925 has a chance to validate correctly. Reported by "Douglas E. Engert"

932 ** libgnutls: gnutls_handshake when sending client hello during a
933 rehandshake, will not offer a version number larger than the current.
934 Reported by Tristan Hill <stan@saticed.me.uk>.
936 ** libgnutls: Permit V1 Certificate Authorities properly.
937 Before they were mistakenly rejected even though
938 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or

994 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
995 The flaw makes it possible for man in the middle attackers (i.e.,
996 active attackers) to assume any name and trick GNU TLS clients into
997 trusting that name. Thanks for report and analysis from Martin von
998 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
1000 Any updates with more details about this vulnerability will be added
1001 to <http://www.gnu.org/software/gnutls/security.html>
1003 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.

1027 ** libgnutls-openssl: fix out of bounds access.
1028 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
1029 from Thomas Viehmann <tv@beamnet.de>.
1031 ** certtool: Use inet_pton for parsing IPv6 addresses.
1033 ** Major changes compared to the v2.4 branch:
1035 *** Added API to replace and update the crypto backend.
1037 *** certtool: can add several subject alternative names via template file.
1039 *** opencdk: Parse (but not decrypt) encrypted secret keys.
1041 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
1042 either set or append alternative names. It can also handle binary structures
1043 such as IP addresses.
1045 *** libgnutls: New function to set minimum acceptable SRP bits.
1046 The function is gnutls_srp_set_prime_bits.
1048 *** libgnutls: Add interface to deal with public key and signature algorithms.
1049 The functions are called gnutls_pk_list, gnutls_pk_get_id,
1050 gnutls_sign_list, and gnutls_sign_get_id.
1052 *** libgnutls: New interfaces to get name of public key and signing algorithms.
1053 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
1055 *** libgnutls: New API to get a string corresponding to a error symbol.
1056 The function is gnutls_strerror_name.
1058 *** libgnutls: New API to set the public parameters in a certificate request
1059 *** from a private key.
1060 The function is gnutls_x509_crq_set_key_rsa_raw.
1062 *** libgnutls: New API to set a callback to extract TLS Finished data.
1063 The function to register is gnutls_session_set_finished_function and
1064 it takes a callback of the gnutls_finished_callback_func type.
1066 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
1068 *** libgnutls: New interface to register a new TLS extension handler.
1069 The new function gnutls_ext_register can be used to register handlers
1070 for specific TLS extension types. The callback functions have the new
1071 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
1072 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
1075 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
1076 The function is gnutls_register_md5_handler. When libgcrypt is in
1077 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
1080 *** API/ABI changes in GnuTLS 2.6
1081 No functions have been removed or modified. The library should be
1082 fully backwards compatible on both the source and binary level.
1084 A new header file <gnutls/crypto.h> have been added. It contains
1085 definitions related to replacing the internal crypto functionality.
1086 All definitions and the header itself is experimental but supported.
1088 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
1089 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
1090 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
1092 The following functions have been added to libgnutls:
1096 gnutls_crypto_bigint_register2
1097 gnutls_crypto_cipher_register2
1098 gnutls_crypto_digest_register2
1099 gnutls_crypto_mac_register2

1132 Report and patch by Jonathan Manktelow.
1134 ** libgnutls: crypto.h gnutls_pk_params_st changes allocation strategy.
1135 The parameters are now allocated in the structure itself.
1137 ** doc: Texinfo HTML manual uses a stylesheet to improve readability.
1139 ** tests: Scripts now use EXEEXT properly.
1140 Modern libtool doesn't create wrapper script, so the self tests need
1141 to invoke certtool.exe under MinGW32+Wine.
1143 ** Uses autoconf 2.63, automake 1.10.1, libtool 2.2.6a.
1144 Automake warnings are now also enabled.
1146 ** API and ABI modifications:
1147 gnutls_pk_params_st: MODIFIED
1149 * Version 2.5.8 (released 2008-09-21)
1151 ** certtool: updated so it can add several subject alternative names using
1154 ** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
1155 either set or append alternative names. It can also handle binary structures
1156 such as IP addresses.
1158 ** libgnutls: Fix crash in hashing code when using non-libgcrypt handlers.
1160 ** libgnutls: New function to set minimum acceptable SRP bits.
1161 The function is gnutls_srp_set_prime_bits. Tiny patch by Kevin Quick
1162 <quick@sparq.org> in <https://savannah.gnu.org/support/index.php?106454>.
1164 ** libgnutls: Check for overflows in gnutls_calloc and gnutls_secure_calloc.
1165 Also fix overflows in calls to those functions. Reported by Werner
1166 Koch <wk@gnupg.org>.
1168 ** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.

1234 * Version 2.5.5 (released 2008-08-29)
1236 ** libgnutls: New API to get a string corresponding to a error symbol.
1237 The function is gnutls_strerror_name.
1239 ** libgnutls: Fix include paths so that building with internal libtasn1 works.
1240 Reported by "jth.net ApS" <info@jth.net>.
1242 ** libgnutls: Fix segmentation fault when generating private keys.
1243 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
1245 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
1246 The code has not worked since v0.9.0 and apparently nobody has missed
1247 it, so we decided to remove the code rather than fix it. If you have
1248 old certificate chains stored in PKCS#7 format, you can convert them
1249 to a list of PEM certificates by using 'certtool --p7-info'. Reported
1250 by Christian Grothoff <christian@grothoff.org>.
1252 ** opencdk: Parse (but not decrypt) encrypted secret keys.
1253 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.

1275 No changes since last version.
1277 * Version 2.5.3 (released 2008-08-14)
1279 ** libgnutls: New API to set the public parameters in a certificate request
1280 ** from a private key.
1281 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
1282 discussion with "Zach C." <fxchip@gmail.com>.
1284 ** libgnutls: New API to set a callback to extract TLS Finished data.
1285 The function to register is gnutls_session_set_finished_function and
1286 it takes a callback of the gnutls_finished_callback_func type.
1288 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
1289 Reported in <https://savannah.gnu.org/support/?106453>.
1291 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
1292 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
1293 names are mapped to the new names in compat.h. These mappings will
1294 likely be removed more quickly than other mappings in that file due to
1295 the namespace violation.
1297 ** libgnutlsxx: Make it build when SRP is disabled.
1299 ** doc: Add doxygen files in doc/doxygen/.
1301 ** API and ABI modifications:

1306 GNUTLS_RANDOM_SIZE: ADDED
1307 TLS_MASTER_SIZE: DEPRECATED
1308 TLS_RANDOM_SIZE: DEPRECATED
1310 * Version 2.5.2 (released 2008-07-08)
1312 ** libgnutls: Fix bug in gnutls_dh_params_generate2.
1313 The prime and generator was swapped.
1315 ** libgnutls: New interface to register a new TLS extension handler.
1316 The new function gnutls_ext_register can be used to register handlers
1317 for specific TLS extension types. The callback functions have the new
1318 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
1319 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
1322 ** Move more code for TLS/IA extension from libgnutls to libgnutls-extra.
1323 This was made possible by using the new gnutls_ext_register interface.
1324 The TLS/IA functionality has only been supported through the
1325 libgnutls-extra library, so it makes sense for the code to belong

1338 ** API and ABI modifications:
1339 No changes since last version.
1341 * Version 2.5.0 (released 2008-07-02)
1343 ** Port fixes from v2.4.1 release, see below.
1345 ** Added API to replace and update the crypto backend.
1346 The header gnutls/crypto.h is now officially supported, and declares
1349 ** Rewritten opencdk crypto backend, to use the gnutls internal one.
1351 ** Update gnulib and translations.
1352 The gnulib gc crypto code has been removed since it was never finished
1353 and is no longer even used. An internal non-libgcrypt crypto
1354 implementation may be added in the future, but we'll decide that later

1368 * Version 2.4.3 (released 2009-02-06)
1370 ** libgnutls: Accept chains where intermediary certs are trusted.
1371 Before GnuTLS needed to validate the entire chain back to a
1372 self-signed certificate. GnuTLS will now stop looking when it has
1373 found an intermediary trusted certificate. The new behaviour is
1374 useful when chains, for example, contains a top-level CA, an
1375 intermediary CA signed using RSA-MD5, and an end-entity certificate.
1376 To avoid chain validation errors due to the RSA-MD5 cert, you can
1377 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
1378 The signature on trusted certificates are not checked, so the chain
1379 has a chance to validate correctly. Reported by "Douglas E. Engert"
1380 <deengert@anl.gov> in
1381 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
1383 ** libgnutls: Permit V1 Certificate Authorities properly.
1384 Before they were mistakenly rejected even though
1385 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
1386 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
1387 "Douglas E. Engert" <deengert@anl.gov> in
1388 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
1390 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
1391 This is a bugfix -- the previous attempt to do this from internal x509
1392 certificate verification procedures did not return the correct value
1393 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
1394 <dkg@fifthhorseman.net> in
1395 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,

1454 If the gnutls_handshake function is called for a normal session, which

1480 * Version 2.4.0 (released 2008-06-19)
1482 ** Major changes compared to the v2.2 branch:
1484 *** The OpenPGP sub-system has been improved and now supports subkeys.
1486 *** The PSK sub-system has been improved and now supports password
1487 *** derivation and PSK identity hints.
1488 The password derivation algorithms support is documented in
1489 draft-ietf-netconf-tls-02.txt.
1491 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
1492 This aligns terminology with OpenPGP, which doesn't use DER encoding.
1493 The old parameters will continue to work for some time.
1495 *** Certtool now confirm passwords and changes permissions of private key files.
1497 *** The default handshake size limit has been increased to 48kb.
1498 It appears as if some valid handshakes are large due to sending many
1499 CA certificates. (The earlier limit was 16kb.)
1501 *** LZO compression is now disabled by default.
1502 The main reason is that LZO compression in TLS is not standardized,
1503 but license compatiblity issues with minilzo triggered us to make this
1506 *** Improvements for cross-compilation to Windows and OpenWRT.
1508 *** The look of the GTK-DOC manual has been improved.
1509 Major developer visible changes compared to the v2.2 branch:
1511 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
1513 *** New APIs to access the raw X.509 Subject and Issuer DN's and
1514 *** elements from the certificate credentials structure.
1515 Thanks to Joe Orton.
1517 *** New APIs to improve working with username/passwords and PSK.
1519 *** Names of constants to affect certificate printing changed.
1520 The constants are used for OpenPGP too, which the names didn't
1521 reflect, so the following name change has been made:
1524 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
1525 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
1526 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
1528 The old names will be mapped to the new names for some time.
1530 *** The function gnutls_openpgp_privkey_get_id has been renamed to
1531 *** gnutls_openpgp_privkey_get_key_id.
1532 A compatibility mapping exists to avoid breaking API backwards
1535 *** Replaced all uses of alloca with malloc and free.
1537 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
1538 We have been unable to find a documented rationale for this practice.
1540 *** Of course, many smaller fixes have been made, see the ChangeLog file.
1542 *** API/ABI changes in GnuTLS 2.4
1543 All OpenPGP related functions have been moved from libgnutls-extra to
1544 libgnutls, and several new functions have been added (see below).
1545 Before making the release, we discussed whether moving functions from
1546 libgnutls-extra to libgnutls would require us to increment the ABI
1547 version, but the general opinion was that this would not be required.
1548 All older functions continue to work the same. We are open to the
1549 possibility that this decision will lead to problem on some platform,
1550 and if it turns out that the Right Thing should have been to increment
1551 the shared library version, we would need to release an update within
1552 the 2.4.x branch that increments the shared library version.
1554 This release adds the following functions:
1556 gnutls_psk_client_get_hint
1557 gnutls_psk_set_server_credentials_hint
1558 gnutls_psk_netconf_derive_key
1560 Used to get/set the PSK identity hint, and derive PSK keys from
1561 passwords a'la netconf.
1563 gnutls_x509_dn_deinit
1564 gnutls_x509_dn_export
1565 gnutls_x509_dn_import
1568 Used to handle X.509 Certificate DN's directly.
1572 Converts a data buffer to hex. Useful for handling PSK/SRP shared
1575 gnutls_certificate_get_x509_cas
1576 gnutls_certificate_get_x509_crls
1577 gnutls_certificate_get_openpgp_keyring
1579 Functions for direct access to credential elements.
1581 gnutls_openpgp_crt_get_auth_subkey
1582 gnutls_openpgp_crt_get_key_id
1583 gnutls_openpgp_crt_get_pk_dsa_raw

1619 gnutls_openpgp_privkey_get_subkey_revoked_status
1620 gnutls_openpgp_privkey_set_preferred_key_id
1622 New OpenPGP related functions.
1624 The function gnutls_openpgp_crt_get_key_id is the same as the old
1625 from gnutls_openpgp_crt_get_id, see above.
1627 The release also adds a new header file 'gnutls/crypto.h', however it
1628 is currently not used.
1630 ** libgnutls [OpenPGP]: New APIs to retrieve fingerprint from OpenPGP subkeys.
1631 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
1633 ** API and ABI modifications:
1634 gnutls_openpgp_crt_get_subkey_fingerprint: ADDED.
1635 gnutls_openpgp_privkey_get_subkey_fingerprint: ADDED.
1637 * Version 2.3.15 (released 2008-06-15)
1639 ** Disable the openpgp-certs self-tests.
1640 It results in failure under Wine and doesn't work on Debian buildds.
1642 ** API and ABI modifications:
1643 No changes since last version.
1645 * Version 2.3.14 (released 2008-06-11)
1647 ** libgnutls [OpenPGP]: Changed OpenPGP verification behaviour.
1648 An OpenPGP certificate is now only considered verified if all the user
1651 ** Examples: Make C++ example compile.
1652 Earlier it may have failed with an unresolved reference to strlen.
1654 ** Documentation: Doc fix for gnutls_x509_crt_get_extension_oid.
1655 Reported by Sam Varshavchik <mrsam@courier-mta.com>.
1657 ** API and ABI modifications:
1658 No changes since last version.
1660 * Version 2.3.13 (released 2008-06-07)
1662 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
1664 ** doc/: Add psktool to info index. Some minor cleanups.
1666 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
1668 ** tests/: Added libgcrypt.supp which can be used with valgrind.
1669 The file suppresses the known libgcrypt memory leaks, so they aren't
1670 printed when you run valgrind on the gnutls self-tests. Use it as
1671 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add
1672 '--suppressions=/home/you/src/gnutls/tests/libgcrypt.supp' to your
1675 ** tests/: Reduce amount of debugging output by default.
1676 Use --verbose for each test to get the full output.
1678 ** tests/: Fix memory leaks in several self-tests.
1679 None of the self tests should be leaking memory when running valgrind
1680 or similar tools. (Known exceptions are dhepskself, pskself, and
1681 set_pkcs12_cred, which appear likely to be due to memory leaks in the
1684 ** API and ABI modifications:
1685 No changes since last version.
1687 * Version 2.3.12 (released 2008-06-04)
1689 ** Merge gnutls_with_netconf branch.
1691 *** libgnutls [PSK]: New API to retrieve PSK identity hint in client.
1692 The function is gnutls_psk_client_get_hint.
1694 *** libgnutls [PSK]: New API to set PSK identity hint in server.
1695 The function is gnutls_psk_set_server_credentials_hint.
1697 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
1698 In the client, the message is parsed and the application can use
1699 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
1700 message is sent if the application has specified a PSK identity hint
1701 using gnutls_psk_set_server_credentials_hint.
1703 *** libgnutls [PSK]: Support Netconf PSK key derivation.
1704 The function gnutls_psk_netconf_derive_key supports the PSK key
1705 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
1708 *** psktool: Support new --netconf-hint to generate PSK key from password.
1709 Uses the Netconf algorithm to derive PSK key from password.
1711 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
1713 *** gnutls-cli: Always support PSK modes, through a callback.
1714 The callback will derive a PSK key using Netconf algorithm. It will
1715 print the PSK identity hint to help the user.
1717 *** New PSK example client and server.
1718 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
1720 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.
1721 The code didn't work properly on platforms where 'char' is unsigned,
1722 when you set version 0. Reported by Laurence Withers
1723 <l@lwithers.me.uk> in
1724 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2825>.
1726 ** libgnutls-openssl: added RAND_pseudo_bytes API.
1727 Patch from Robert Millan <rmh@aybabtu.com>.
1729 ** API and ABI modifications:
1730 RAND_pseudo_bytes: ADDED to libgnutls-openssl.
1731 gnutls_psk_client_get_hint: ADDED.
1732 gnutls_psk_set_server_credentials_hint: ADDED.
1733 gnutls_psk_netconf_derive_key: ADDED
1735 * Version 2.3.11 (released 2008-05-20)
1737 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
1738 The flaw would result in incorrectly terminated sessions with the
1739 error "Decryption has failed" when the server sends a small packet
1740 (typically when the session is closed). Reported by Andreas Metzler
1741 <ametzler@downhill.at.eu.org> in
1742 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
1744 ** Don't use gnulib headers when building C++ library.
1745 Fixes builds under Windows.
1747 ** Make umask a requirement.
1748 We don't know of any system that lacks it, even GNU CoreUtils use it
1751 ** Update gnulib files.
1752 Fixes a problem where it pulled in a replacement for memcmp under
1753 MinGW, which caused the C++ example to fail to build.
1755 ** API and ABI modifications:
1756 No changes since last version.
1758 * Version 2.3.10 (released 2008-05-19)
1760 ** Added wide wildcard hostname matching.
1761 Tiny patch by Jean-Philippe Garcia Ballester.
1763 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
1764 Thanks to CERT-FI for finding the bugs and providing detailed reports,
1765 which allowed the bugs to be reproduced and fixed easily. Patches
1766 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
1767 with more details about these vulnerabilities will be added to
1768 <http://www.gnu.org/software/gnutls/security.html>
1770 *** [GNUTLS-SA-2008-1-1]
1771 *** libgnutls: Fix crash when sending invalid server name.
1772 The crash can be triggered remotely before authentication, which can
1773 lead to a Daniel of Service attack to disable the server. The bug
1774 cause gnutls to store more session resumption data than what was
1775 allocated for, thus overwriting unallocated memory.
1777 *** [GNUTLS-SA-2008-1-2]
1778 *** libgnutls: Fix crash when sending repeated client hellos.
1779 The crash can be triggered remotely before authentication, which can
1780 lead to a Daniel of Service attack to disable the server. The bug
1781 triggers a null-pointer dereference.
1783 *** [GNUTLS-SA-2008-1-3]
1784 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
1785 The crash can be triggered remotely before authentication, which can
1786 lead to a Daniel of Service attack to disable the server. The bug
1787 cause gnutls to read memory beyond the end of the received record.
1789 ** libgnutlsxx: Updated API according to patches from Eduardo
1790 Villanueva Che (discussion at
1791 <http://lists.gnu.org/archive/html/gnutls-devel/2007-02/msg00017.html>)
1793 ** Use umask to restrict permissions to owner before creating a file.
1795 ** API and ABI modifications:
1796 No changes since last version.
1798 * Version 2.3.9 (released 2008-05-16)
1800 ** libgnutls: Fix build failures if SRP/OpenPGP is disabled.
1801 Based on report and tiny patches from
1802 <jared.jennings.ctr@eglin.af.mil>, see
1803 <https://savannah.gnu.org/support/index.php?106342>.
1805 ** libgnutls: Translation fixes.
1807 ** gnutls-cli: Fix so that PSK authentication works.
1808 Also improve manual to give example for gnutls-cli PSK authentication.
1810 ** certtool: Encrypting a private key now require a confirmed password.
1811 Before './certtool -k -8' would merely ask for a password once.
1812 Reported by Daniel 'NebuchadnezzaR' Dehennin
1813 <nebuchadnezzar@asgardr.info> see
1814 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
1816 ** certtool: When writing private keys to files, change permissions of file.
1817 Now the file which the private key is saved to is chmod'ed 0600.
1818 Reported by martin f krafft <madduck@debian.org> see
1819 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
1821 ** guile: Fix -fgnu89-inline test.
1823 ** Removed --enable-profile-mode.
1824 The code linked gnutls with the libfc project (Function Check) which
1825 appears to have been stalled since around 2002.
1827 ** Clean up header file checks by ./configure.
1829 ** Update of gnulib files.
1831 ** API and ABI modifications:
1832 No changes since last version.
1834 * Version 2.3.8 (released 2008-04-29)
1836 ** libgnutls: Increase default handshake packet size limit to 48kb.
1837 The old limit was 16kb and some servers send huge list of trusted CAs,
1838 thus running into the limit. FYI, applications can further increase
1839 this limit using gnutls_handshake_set_max_packet_length. Thanks to
1840 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
1841 <marc@mclemente.net> for reporting and providing test servers.
1843 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
1844 Returned when the handshake data size is too large. Before
1845 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
1848 ** libgnutls: Hide definitions in crypto.h.
1849 We have decided that the APIs defined in crypto.h are not stable
1850 enough for v2.4, so don't use any of those functions.
1852 ** gnutls-cli: exit when hostname doesn't match certificate.
1853 Use --insecure to avoid hostname comparison.
1855 ** certtool: --inder and --outder replaced by --inraw and --outraw.
1856 The reason is to align terminology with OpenPGP, which doesn't use
1857 DER. The old parameters will continue to work for some time.
1859 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
1861 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
1863 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
1864 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
1865 vasprintf symbol from the libgcrypt library which caused problems.
1867 ** Update of gnulib files.
1869 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
1871 ** API and ABI modifications:
1872 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
1874 * Version 2.3.7 (released 2008-04-21)
1876 ** opencdk now properly sets the key usage bits into openpgp keys.
1878 ** gnutls-cli: Fix crash on TLS handshake failures.
1879 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
1880 This is similar to <http://bugs.debian.org/429183>.
1882 ** certtool: with --generate-request and newly generated keys, print the key.
1884 ** Build fixes for MinGW.
1885 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
1886 with -lws2_32 when needed. Use ASCII only isprint() when printing
1887 X.509 certificate information, to avoid non-ASCII but printable
1888 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
1891 ** Update internal copy of libtasn1 to version 1.4.
1893 ** API and ABI modifications:
1894 No changes since last version.
1896 * Version 2.3.6 (released 2008-04-17)
1898 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
1899 ** Improve documentation for gnutls_x509_crq_sign2.
1900 Based on report from "John Brooks" <aspecialj@gmail.com> in
1901 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
1903 ** tests/pathlen: run diff without parameters to improve portability.
1904 Based on HPUX build hints in
1905 <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>.

1908 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
1909 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
1911 ** Remove all uses of gnutls_alloca/gnutls_afree.
1912 Use normal gnutls_malloc instead. One reason is increased portability
1913 to Windows, the other is that several of the uses may be unsafe
1914 because the size of data allocated could be large. Reported by
1915 Massimo Gaspari <massimo.gaspari@alice.it> in
1916 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
1918 ** Build Guile code with -fgnu89-inline only when supported.
1919 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
1920 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
1922 ** Several GTK-DOC related fixes.
1924 ** Clean up OpenCDK related code.
1925 GnuTLS now requires its internal OpenCDK code rather than the external
1926 GPL library OpenCDK. Unfortunately, we don't have resources to
1927 maintain an external library (help welcome).
1929 ** API and ABI modifications:
1930 No changes since last version.
1932 * Version 2.3.5 (released 2008-04-14)
1934 ** Build fix for MinGW and --disable-shared.

1938 ** Document how to generate CRLs.
1939 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
1941 ** Documented the --priority option to gnutls-cli and gnutls-serv.
1943 ** Several minor fixes in the OpenPGP interface.
1944 Thanks to Daniel Kahn Gillmor.
1946 ** Fix fopen file descriptor leak in PSK server code.
1947 Thanks to Laurence Withers <l@lwithers.me.uk>, see
1948 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
1950 ** Translations files not stored directly in git to avoid merge conflicts.
1952 ** New APIs to let applications replace the RNG used.
1953 Update all RNG callers in the code to use the new interface.
1955 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
1957 ** Update gnulib files.
1959 ** API and ABI modifications:
1960 gnutls_crypto_rnd_register: ADDED
1961 gnutls_rnd_level_t: ADDED
1962 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
1963 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
1964 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
1965 gnutls_crypto_rnd_st: ADDED
1966 GNUTLS_DIG_SHA224: ADDED
1967 GNUTLS_SIGN_RSA_SHA224: ADDED
1968 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
1970 * Version 2.3.4 (released 2008-03-19)
1972 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
1973 They weren't renamed in the public header file.
1975 ** Added functions to register a cipher/mac/digest. This allows to
1976 override the included ones.
1978 ** Fix a bunch of compiler warnings.
1980 ** API and ABI modifications:
1981 gnutls_crypto_cipher_st: ADDED
1982 gnutls_crypto_mac_st: ADDED
1983 gnutls_crypto_digest_st: ADDED
1984 gnutls_crypto_cipher_register: ADDED
1985 gnutls_crypto_mac_register: ADDED
1986 gnutls_crypto_digest_register: ADDED
1987 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
1989 * Version 2.3.3 (released 2008-03-10)
1991 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
1992 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
1994 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
1995 We could not find any modern justification for enabling these flags by
1996 default. If you know of some platform that needs one of the flags to
1997 work properly, please let us know. (Actually introduced in v2.3.0 but
1998 not documented until now.)
2000 ** Importing many CA certificates are now considerably faster.
2001 This affect gnutls_certificate_set_x509_trust_mem,
2002 gnutls_certificate_set_x509_trust, and
2003 gnutls_certificate_set_x509_trust_file. The complexity was reduced
2004 from O(2*n^2) to O(n). When adding 206 files containing 408
2005 certificates, using gnutls_certificate_set_x509_trust_file, the time
2006 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
2007 to trigger the problem. See also
2008 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
2010 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
2011 ** to be explicit that it takes zero terminated data.
2013 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.

2134 GNUTLS_CRT_PRINT_UNSIGNED_FULL: ADDED, same as
2135 old GNUTLS_X509_CRT_UNSIGNED_FULL.
2137 * Version 2.3.0 (released 2008-01-08)
2139 ** LZO compression is now disabled by default.
2140 The reason is that LZO compression is not standardized in TLS. If you
2141 wish to experiment with it, you will have to supply --with-lzo when
2142 invoking ./configure. The internal copy of minilzo is no longer
2143 included with GnuTLS, so you will need to install liblzo or liblzo2 on
2144 your system to have --with-lzo to be effective.
2146 ** More than one server name field is now sent to the server properly.
2147 Thanks to mark.phillips@virgin.net.
2149 ** Fixes the post_client_hello_function(). The extensions are now parsed
2150 in a callback friendly way.
2152 ** Fix for certificate selection in servers with certificate callbacks.
2154 ** Updated translations.
2156 ** Update gnulib files.
2158 ** API and ABI modifications:
2159 No changes since last version.
2161 * Version 2.2.5 (released 2008-05-19)
2163 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
2164 The flaw would result in incorrectly terminated sessions with the
2165 error "Decryption has failed" when the server sends a small packet
2166 (typically when the session is closed). Reported by Andreas Metzler
2167 <ametzler@downhill.at.eu.org> in
2168 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
2170 ** API and ABI modifications:
2171 No changes since last version.
2173 * Version 2.2.4 (released 2008-05-19)
2175 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
2176 Thanks to CERT-FI for finding the bugs and providing detailed reports,
2177 which allowed the bugs to be reproduced and fixed easily. Patches
2178 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
2179 with more details about these vulnerabilities will be added to
2180 <http://www.gnu.org/software/gnutls/security.html>
2182 *** [GNUTLS-SA-2008-1-1]
2183 *** libgnutls: Fix crash when sending invalid server name.
2184 The crash can be triggered remotely before authentication, which can
2185 lead to a Daniel of Service attack to disable the server. The bug
2186 cause gnutls to store more session resumption data than what was
2187 allocated for, thus overwriting unallocated memory.
2189 *** [GNUTLS-SA-2008-1-2]
2190 *** libgnutls: Fix crash when sending repeated client hellos.
2191 The crash can be triggered remotely before authentication, which can
2192 lead to a Daniel of Service attack to disable the server. The bug
2193 triggers a null-pointer dereference.
2195 *** [GNUTLS-SA-2008-1-3]
2196 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
2197 The crash can be triggered remotely before authentication, which can
2198 lead to a Daniel of Service attack to disable the server. The bug
2199 cause gnutls to read memory beyond the end of the received record.
2201 ** API and ABI modifications:
2202 No changes since last version.
2204 * Version 2.2.3 (released 2008-05-06)
2206 ** Increase default handshake packet size limit to 48kb.
2207 The old limit was 16kb and some servers send huge list of trusted CAs,
2208 thus running into the limit. FYI, applications can further increase
2209 this limit using gnutls_handshake_set_max_packet_length. Thanks to
2210 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
2211 <marc@mclemente.net> for reporting and providing test servers.
2213 ** Fix compilation error related to __FUNCTION__ on some systems.
2214 Reported by Tim Mooney, see
2215 <https://savannah.gnu.org/support/?106267>.
2217 ** Documented the --priority option to gnutls-cli and gnutls-serv.
2219 ** Fix fopen file descriptor leak in PSK server code.
2220 Thanks to Laurence Withers <l@lwithers.me.uk>, see
2221 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
2223 ** Build Guile code with -fgnu89-inline only when supported.
2224 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
2225 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
2227 ** Make Camellia encryption work.
2228 Reported by Yoshisato YANAGISAWA <yanagisawa@csg.is.titech.ac.jp> in
2229 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2746>.
2231 ** API and ABI modifications:
2232 No changes since last version.
2234 * Version 2.2.2 (released 2008-02-21)
2236 ** Cipher priority string handling now handle strings that starts with NULL.
2237 Thanks to Laurence Withers <l@lwithers.me.uk>.
2239 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
2242 ** Increased the default certificate verification chain limits and allowed
2243 for checks without limitation.
2245 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
2246 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
2247 strings and return the proper size.
2249 ** API and ABI modifications:
2250 No changes since last version.
2252 * Version 2.2.1 (released 2008-01-17)
2254 ** Prevent linking libextra against previously installed libgnutls.
2255 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
2256 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
2258 ** Fixes the post_client_hello_function(). The extensions are now parsed
2259 in a callback friendly way.
2261 ** Fix for certificate selection in servers with certificate callbacks.
2263 ** API and ABI modifications:
2264 No changes since last version.
2266 * Version 2.2.0 (released 2007-12-14)
2268 ** Update internal copy of libtasn1 to version 1.2.
2270 ** Certtool --verify-chain now handle inputs larger than 64kb.
2271 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
2272 recent versions of libgcrypt. The problem was that Wine with the
2273 libgcrypt RNG generates huge amounts of debugging output.
2275 ** Translation updates.
2276 Added Dutch translation. Updated Polish and Swedish translation.
2278 ** Major changes compared to the v2.0 branch:
2280 *** SRP support aligned with newly published RFC 5054.
2282 *** OpenPGP support aligned with newly published RFC 5081.
2284 *** Support for DSA2 keys.
2286 *** Support for Camellia cipher.
2288 *** Support for Opaque PRF Input extension.
2290 *** PKCS#8 parser now handle DSA keys.
2292 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
2293 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
2294 versions, such as 2.01 which is included with GnuTLS, is available
2295 under GPLv2 or later. If this incompatibility causes problems, we
2296 recommend you to disable LZO using --without-lzo. LZO compression is
2297 not a standard TLS compression algorithm, so the impact should be
2300 *** Functions for disabling record protocol padding.
2301 Works around bugs on Nokia/Ericsson phones.
2303 *** New functions gnutls_priority_set() for setting cipher priorities easily.
2304 Priorities like "COMPAT" also enables other work arounds, such as
2307 *** Other minor improvements and bug fixes.
2309 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
2310 To adapt to changes in the TLS extension specifications for OpenPGP
2311 and SRP, the GnuTLS API had to be modified. This means breaking the
2312 API and ABI backwards compatibility. That is something we try to
2313 avoid unless it is necessary. We decided to also remove the already
2314 deprecated stub functions for X.509 to XML conversion and TLS
2315 authorization (see below) when we had the opportunity.
2317 Generally, most applications does not need to be modified. Just
2318 re-compile them against the latest GnuTLS release, and it should work
2321 Applications that use the OpenPGP or SRP features needs to be
2322 modified. Below is a list of the modified APIs and discussion of what
2323 the minimal things you need to modify in your application to make it
2324 work with GnuTLS 2.2.
2326 Note that GnuTLS 2.2 also introduces new APIs -- such as
2327 gnutls_set_priority() that is superior to
2328 gnutls_set_default_priority() -- that you may want to start using.
2329 However, using those new APIs is not required to use GnuTLS 2.2 since
2330 the old functions continue are still supported. This text only
2331 discuss what you minimally have to modify.
2333 *** XML related changes
2334 The function `gnutls_x509_crt_to_xml' has been removed. It has been
2335 deprecated and only returned an error code since GnuTLS version
2336 1.2.11. Nobody has complained, so users doesn't seem to miss the
2337 functionality. We don't know of any other library to convert X.509
2338 certificates into XML format, but we decided (long ago) that GnuTLS
2339 isn't the right place for this kind of functionality. If you want
2340 help to find some other library to use here, please explain and
2341 discuss your use case on help-gnutls@gnu.org.
2343 *** TLS Authorization related changes
2344 Everything related to TLS authorizations have been removed, they were
2345 only stub functions that returned an error code:
2347 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
2348 gnutls_authz_data_format_type_t
2349 gnutls_authz_recv_callback_func
2350 gnutls_authz_send_callback_func
2352 gnutls_authz_send_x509_attr_cert
2353 gnutls_authz_send_saml_assertion
2354 gnutls_authz_send_x509_attr_cert_url
2355 gnutls_authz_send_saml_assertion_url
2357 *** SRP related changes
2358 The callback gnutls_srp_client_credentials_function has a new
2359 prototype, and its semantic has changed. You need to rewrite the
2360 callback, see the updated function documentation and SRP example code
2361 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
2364 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
2365 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
2366 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
2367 used. There are #define's to map the old names to the new. You may
2368 run into problems if you have a switch-case with cases for both SRP
2369 alerts, since they are now mapped to the same value. The solution is
2370 to drop the SRP alerts from such switch cases, as they are now
2371 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
2373 *** OpenPGP related changes
2374 The function `gnutls_certificate_set_openpgp_keyserver' have been
2375 removed. There is no replacement functionality inside GnuTLS. If you
2376 need keyserver functionality, consider using the GnuPG tools.
2378 All functions, types, and error codes related to OpenPGP trustdb
2379 format have been removed. The trustdb format is a non-standard
2380 GnuPG-specific format, and we recommend you to use key rings instead.
2381 The following have been removed:
2383 gnutls_certificate_set_openpgp_trustdb
2384 gnutls_openpgp_trustdb_init
2385 gnutls_openpgp_trustdb_deinit
2386 gnutls_openpgp_trustdb_import
2387 gnutls_openpgp_key_verify_trustdb
2388 gnutls_openpgp_trustdb_t
2389 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
2391 The following functions has an added parameter of the (new) type
2392 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
2393 (binary or base64). The functions are:
2394 gnutls_certificate_set_openpgp_key_file
2395 gnutls_certificate_set_openpgp_key_mem
2396 gnutls_certificate_set_openpgp_keyring_mem
2397 gnutls_certificate_set_openpgp_keyring_file
2399 To improve terminology and align with the X.509 interface, some
2400 functions have been renamed. Compatibility mappings exists. The old
2401 and new names of the affected functions and types are:
2404 gnutls_openpgp_key_t gnutls_openpgp_crt_t
2405 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
2406 gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
2407 GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
2408 GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
2409 gnutls_openpgp_key_init gnutls_openpgp_crt_init
2410 gnutls_openpgp_key_deinit gnutls_openpgp_crt_deinit

2505 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
2506 documented. This caused some problems (e.g., debian #450854). To
2507 avoid backwards compatibility problems, this release revert this
2508 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
2509 done in GnuTLS 2.0.x and earlier, and add a new error code
2510 GNUTLS_E_UNKNOWN_ALGORITHM.
2512 ** Fixes several gtk-doc warnings.
2514 ** API and ABI modifications:
2515 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
2516 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
2517 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
2519 * Version 2.1.5 (released 2007-11-01)
2521 ** Fix PKCS#3 parameter export problem.
2523 ** Improve certtool queries, they now print the default value.
2527 ** Update gnulib files.
2529 ** API and ABI modifications:
2530 No changes since last version.
2532 * Version 2.1.4 (released 2007-10-27)
2534 ** Added the --v1 option to certtool, to allow generating X.509
2535 version 1 certificates.
2537 ** certtool: Add option --disable-quick-random to enable the old behaviour
2538 of using /dev/random to generate keys.
2540 ** Added priority functions that accept strings.
2542 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
2543 priorities preferences.
2545 ** Added gnutls_record_disable_padding() to allow servers talking to
2546 buggy clients that complain if the TLS 1.0 record protocol padding is
2549 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
2550 all supported compatibility options (like disabling padding).
2552 ** The gnutls_certificate_set_openpgp_* functions were modified to include
2553 the format. This makes the interface consistent with the x509 functions.
2555 ** Internal copy of OpenCDK upgraded to version 0.6.5.

2594 * Version 2.1.3 (released 2007-10-17)
2596 ** TLS authorization support removed.
2597 This technique may be patented in the future, and it is not of crucial
2598 importance for the Internet community. After deliberation we have
2599 concluded that the best thing we can do in this situation is to
2600 encourage society not to adopt this technique. We have decided to
2601 lead the way with our own actions.
2603 ** Re-enabled the 256 bit ciphers in the default priorities.
2605 ** Corrected bugs in openpgp key verification using a keyring (both in

2618 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
2619 gnutls_supplemental_data_format_type_t enum type becomes empty.
2621 * Version 2.1.2 (released 2007-10-14)
2623 ** Removed all the trustdb code from openpgp authentication.
2624 We now use only the well-specified keyrings.
2626 ** The 256 bit ciphers are not enabled in the default priorities.
2628 ** Added support for DSA2 using libgcrypt 1.3.0.
2630 ** certtool: Fixed data corruption when using --outder.
2632 ** Removed all the xml related stubs and functions.
2634 ** Added capability to set a callback after the client hello is received
2635 by the server in order to adjust parameters before the handshake.
2637 ** SRP was corrected to adhere to the latest draft (published soon as RFC)
2639 ** Corrected bug which did not allow a server to run without supporting

2663 * Version 2.1.1 (released 2007-09-24)
2665 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
2666 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
2667 compiled with Camellia support. See the libgcrypt documentation on
2668 how to enable it. Unconditionally disable it using the configure
2669 option --disable-camellia. Fixes #1.
2671 ** Properly document in the NEWS file the API change in the last release.
2673 ** API and ABI modifications:
2674 No changes since last version.
2676 * Version 2.1.0 (released 2007-09-20)
2678 ** Support for draft-rescorla-tls-opaque-prf-input-00.txt.
2679 The support is disabled by default. Since no value has been allocated
2680 by the IANA for this extension yet, you will need to provide one
2681 yourself by invoking './configure --enable-opaque-prf-input=42'.
2684 ** Example code: Fix compilation flaw under MinGW.
2686 ** API and ABI modifications:
2687 gnutls_oprfi_callback_func: ADD, new typedef function prototype.
2688 gnutls_oprfi_enable_client: ADD, new function.
2689 gnutls_oprfi_enable_server: ADD, new function.
2691 * Version 2.0.4 (released 2007-11-16)
2693 ** Corrected bug in decompression of expanded compression data.
2695 ** API and ABI modifications:
2696 No changes since last version.
2698 * Version 2.0.3 (released 2007-11-10)
2700 ** This version backports several fixes from the 2.1.x branch.
2702 ** Fixed PKCS #3 parameter export.
2704 ** Added gnutls_record_disable_padding() to allow servers talking to
2705 buggy clients that complain if the TLS 1.0 record protocol padding is

2716 gnutls_record_disable_padding: ADDED
2718 * Version 2.0.2 (released 2007-10-17)
2720 ** TLS authorization support removed.
2721 This technique may be patented in the future, and it is not of crucial
2722 importance for the Internet community. After deliberation we have
2723 concluded that the best thing we can do in this situation is to
2724 encourage society not to adopt this technique. We have decided to
2725 lead the way with our own actions.
2727 ** certtool: Fixed data corruption when using --outder.
2729 ** Fix configure-time Guile detection.
2731 ** API and ABI modifications:
2732 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
2733 gnutls_supplemental_data_format_type_t enum type becomes empty.
2735 * Version 2.0.1 (released 2007-09-20)
2737 ** New directory doc/credentials/ with test credentials.
2738 This collects the test credentials from the web page and from src/.
2739 The script gnutls-http-serv has also been moved to that directory.
2741 ** Update SRP extension type and cipher suite with official IANA values.
2742 This breaks backwards compatibility with SRP in older versions of
2743 GnuTLS, but this is intentional to speed up the adoption of the
2744 official values. The old values we used were incorrect.
2746 ** Guile: Fix `x509-certificate-dn-oid'
2748 ** API and ABI modifications:
2749 No changes since last version.
2751 * Version 2.0.0 (released 2007-09-04)
2753 ** Included copy of Libtasn1 upgraded to version 1.1.
2755 ** Disable building of some examples if anonymous ciphers are disabled.
2757 ** Don't build examples for disabled features.
2759 ** API and ABI modifications:
2760 No changes since last version.
2762 * Version 1.7.19 (released 2007-08-27)
2764 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
2765 This solves connection problems in mutt, see
2766 <http://bugs.debian.org/439640>.
2768 ** Update gnulib files.
2769 In particular, the getpass module -- with its dependencies on getline,
2770 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
2771 library) directory to the gl/ directory (only used by the command line
2772 tools). The reason is that getpass is now only used by the
2773 command-line tools, and reducing the number of gnulib modules linked
2774 to the core library helps portability and reduces size.
2778 ** Disable building of PGP examples if PGP is disabled.
2780 ** Included copy of OpenCDK upgraded to version 0.6.4.
2782 ** API and ABI modifications:
2783 No changes since last version.
2785 * Version 1.7.18 (released 2007-08-16)
2787 ** Install images for the info manual.
2788 This has a side effect of renaming the images. See
2789 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
2790 discussions on the approach chosen.
2792 ** Fix pointer mix to variables of different size.
2793 Patch extracted from
2794 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
2796 ** Fix warnings during build.
2797 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
2799 ** API and ABI modifications:
2800 No changes since last version.
2802 * Version 1.7.17 (released 2007-08-15)
2804 ** New functions to perform external signing.
2805 Set the signing callback function (of the gnutls_sign_func prototype)
2806 using the gnutls_sign_callback_set function. In the callback, you may
2807 find the new functions gnutls_x509_privkey_sign_hash and
2808 gnutls_openpgp_privkey_sign_hash useful. A new function
2809 gnutls_sign_callback_get is also added, to retrieve the function
2810 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
2811 comments and testing.
2813 ** New self test of client and server authenticated X.509 TLS sessions.
2814 See tests/x509self.c and tests/x509signself.c. The latter also tests
2815 the new external signing callback interface.
2817 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
2818 These two actually describe the outer limits of a range of error codes
2819 reserved to the application. All of the errors are treated as fatal
2820 by the library (it has to since it doesn't know the semantics of the
2821 error codes). This can be useful in callbacks, to signal some
2822 application-specific error condition, which will usually eventually
2823 cause some gnutls API to return the same error code as the callback,
2824 which then can be inspected by the application. Note that error codes
2827 ** gnutls_set_default_priority now disable TLS 1.2 by default.
2828 The RFC is not released yet, and we're approaching a major release so
2829 let's not enable it just yet.
2831 ** Fix namespace so that gnutls_*_t is used consistently.
2832 Before, many places in the GnuTLS code used the old deprecated type
2833 names without the '_t' suffix.
2835 ** Build fixes for Guile code.
2836 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
2838 ** More documentation fixes.
2839 In particular, the section headings were modified for casing. By
2840 Ludovic Courtes <ludovic.courtes@laas.fr>.
2842 ** Updated Polish and Swedish translations.
2843 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
2844 <po@danielnylander.se>.
2846 ** API and ABI modifications:
2847 gnutls_sign_func: ADD, new type for sign callback.
2848 gnutls_sign_callback_set: ADD, new function to set sign callback.
2849 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
2850 gnutls_x509_privkey_sign_hash,
2851 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
2852 GNUTLS_E_APPLICATION_ERROR_MIN,
2853 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
2855 * Version 1.7.16 (released 2007-08-07)
2857 ** Fix sanity checks and return values in certificate selection.
2858 In some cases, GnuTLS omitted to report suitable error codes when no
2859 suitable certificate was found.
2861 ** Fix gnutls-cli starttls EOF on Mac OS X.
2862 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
2864 ** Documentation fixes.
2865 In particular, the section headings were modified for casing. By
2866 Ludovic Courtes <ludovic.courtes@laas.fr>.
2868 ** Update gnulib files.
2870 ** API and ABI modifications:
2871 No changes since last version.
2873 * Version 1.7.15 (released 2007-07-02)
2875 ** Fix self-tests key-id under mingw32.
2877 ** Test that the Guile header files are recent enough to work.
2878 Before we just tested that the command line tool 'guile' was recent
2879 enough, which may not be sufficient if you still have an old
2880 libguile.h header installed.
2882 ** Guile bindings are now installed under $prefix by default.
2883 Use --without-guile-site-dir to install it under $pkgdatadir/site/
2884 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
2885 Use --with-guile-site-dir=/your/own/path to specify the path manually.
2886 The default, --with-guile-site-dir, will install the Guile bindings
2887 under $datadir/guile/site. There is a new section 'Guile
2888 Preparations' in the manual that discuss these issues.
2890 ** Fix run-time library path ordering in linking the Guile bindings.
2892 ** Improved manual on downloading, installing, getting help, bug reports etc.
2893 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
2895 ** Add Malay message translations.

2903 ** Don't enable Guile bindings unless we have Guile 1.8 or later.
2904 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
2906 ** Fix memory leak during DSA signature verification.
2907 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.

2933 ** Build fixes for GnuTLS Guile bindings.
2934 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
2936 ** Build fix for GTK-DOC manual.

2943 * Version 1.7.12 (released 2007-06-08)
2945 ** Guile bindings for GnuTLS have been included.
2946 Contributed by Ludovic Courtès <ludovic.courtes@laas.fr>. There is a
2947 new chapter 'Guile Bindings' in the manual.
2949 ** Have PKCS8 parser return better error codes.

2952 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
2954 ** Fix mem leak for sessions with client authentication via certificates.
2955 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
2956 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
2959 Reported by Dennis Vshivkov <walrus@amur.ru>, see
2960 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333050>. Added
2961 self-test tests/parse_ca.c to test regressions.
2963 ** Fix build failures related to missing images in manual.
2964 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.

2968 ** API and ABI modifications:
2969 No changes since last version.
2971 * Version 1.7.11 (released 2007-05-26)
2973 ** Include opencdk.h in the release.
2974 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
2976 ** API and ABI modifications:
2977 No changes since last version.
2979 * Version 1.7.10 (released 2007-05-25)
2981 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
2982 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
2984 ** Update of gnulib files.
2986 ** GnuTLS is now developed in GIT instead of CVS.
2987 See <http://repo.or.cz/w/gnutls.git> for a public repository.
2989 ** API and ABI modifications:
2990 gnutls_x509_crt_get_raw_issuer_dn: ADD.
2991 gnutls_x509_crt_get_raw_dn: ADD.
2993 * Version 1.7.9 (released 2007-05-12)
2995 ** X.509 certificates are preferred over OpenPGP keys.
2996 This is a change in the semantics of gnutls_set_default_priority.
2998 ** The included copy of OpenCDK has been updated to 0.6.1.
2999 There has been some API changes in OpenCDK, and the GnuTLS layer have
3000 been modified as well. Note that while there are API/ABI incompatible
3001 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
3002 its API/ABI have not changed. From this version on, GnuTLS requires
3003 OpenCDK 0.6.0 or later.
3005 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
3007 ** Change certtool's default serial number from 0 to a time-based value.
3009 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
3010 Before, we remove the parameters field, which resulted in a slightly
3011 different DER encoding which in turn caused signature verification
3012 failures of GnuTLS-generated RSA certificates in some other
3013 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
3014 you read, this may or may not be correct, but our new behaviour appear
3015 to be consistent with other widely used implementations.
3017 ** Fix mem leaks in gnutls_x509_crt_print.
3019 ** API and ABI modifications:
3020 No changes since last version.
3022 * Version 1.7.8 (released 2007-04-16)
3024 ** Added examples for the authorization extension.
3025 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
3027 ** The examples only use gnutls_set_default_priority().
3028 The exception is when DH_ANON is needed.
3030 ** Improve gnutls_set_default_priority() priorities.
3031 The new approach is for it to try and negotiate all secure and
3032 standard mechanisms available. Currently, DH_ANON ciphersuites and
3033 LZO compressions are not enabled by default, because they are,
3034 respectively, insecure and non-standardized. Note that TLS 1.2 will
3035 not be enabled by default in non-experimental release until it has
3036 been approved by the IETF.
3038 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
3039 This means that to get DH_ANON and LZO compression, you'll need to
3040 specify that manually using '--kx anon' or '--comp lzo'.
3042 ** Minor fixes to the human display format of X.509 certificates.
3044 ** New APIs to extract Distinguished Name's from X.509 certificates.
3045 Based on patch from Howard Chu <hyc@symas.com>.
3047 ** Improved library searching for opencdk.
3048 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
3049 The deprecated opencdk.m4 is no longer used.
3051 ** New APIs to list supported algorithms in the library.
3052 The APIs are gnutls_cipher_list, gnutls_mac_list,
3053 gnutls_compression_list, gnutls_protocol_list,
3054 gnutls_certificate_type_list, gnutls_kx_list, and
3055 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
3057 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
3059 ** New configure option --disable-tls-authorization to disable tls-authz.
3061 ** Fix prototype for `gnutls_psk_set_client_credentials'.
3062 The last parameter was renamed from 'flags' to 'format' and the type
3063 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
3064 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
3067 ** Fix allocation in gnutls_certificate_set_openpgp_key.
3068 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
3070 ** API and ABI modifications:
3071 gnutls_x509_dn_t: ADD.
3072 gnutls_x509_ava_st: ADD.
3073 gnutls_x509_crt_get_subject,
3074 gnutls_x509_crt_get_issuer: ADD.
3075 gnutls_x509_dn_get_rdn_ava: ADD.
3076 gnutls_cipher_list: ADD.
3077 gnutls_mac_list: ADD.
3078 gnutls_compression_list: ADD.
3079 gnutls_protocol_list: ADD.
3080 gnutls_certificate_type_list: ADD.
3081 gnutls_kx_list: ADD.
3082 gnutls_cipher_suite_info: ADD.
3084 * Version 1.7.7 (released 2007-02-22)
3086 ** Support for supplemental handshake messages and authorization data.
3087 Supplemental data is described in RFC 4680 and the authorization
3088 extensions in draft-housley-tls-authz-extns-07.
3090 ** Support for authorization data in gnutls-cli and gnutls-serv.
3091 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
3093 ** Fix for gnutls_x509_crt_check_hostname.
3094 Before it would have reported that the certificate matched a hostname
3095 when it did not have any dNSName or any CN field. Report and tiny
3096 patch from "Richard W.M. Jones" <rjones@redhat.com>.
3098 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
3099 Tests regressions of the bug, and several other features.
3101 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
3102 Before there were no support for iPAddress SAN's during comparison.
3104 ** New API to print information about CRL's.
3105 The function is gnutls_x509_crl_print.
3107 ** New API to extract signature value from CRL's.
3108 The function is gnutls_x509_crl_get_signature.
3110 ** Support for directoryName Subject Alternative Name's.
3111 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
3112 string in the provided buffer.
3114 ** Internal improvements to certtool.
3115 It uses gnutls_x509_crl_print to print CRL information. It uses some
3116 more gnulib modules to simplify error handling.
3118 ** API and ABI modifications:
3119 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
3120 gnutls_supplemental_data_format_type_t: ADD.
3121 gnutls_authz_data_format_type_t: ADD.
3122 gnutls_supplemental_get_name: ADD.
3123 gnutls_authz_recv_callback_func,
3124 gnutls_authz_send_callback_func: ADD, callback prototypes.
3125 gnutls_authz_enable: ADD.
3126 gnutls_authz_send_x509_attr_cert,
3127 gnutls_authz_send_saml_assertion,
3128 gnutls_authz_send_x509_attr_cert_url,
3129 gnutls_authz_send_saml_assertion_url: ADD.
3130 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
3131 gnutls_x509_crl_print: ADD.
3132 gnutls_x509_crl_get_signature: ADD.
3134 * Version 1.7.6 (released 2007-02-12)
3136 ** Support for 'otherName' Subject Alternative Names.
3137 The existing API gnutls_x509_crt_get_subject_alt_name may now return
3138 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
3139 To find out the otherName OID (necessary for proper parsing of the
3140 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
3141 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
3142 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
3143 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
3145 ** Certtool can print otherName SAN values for certificates.
3146 For known otherName OIDs (currently only id-on-xmppAddr as defined by
3147 RFC 3920), it will also print the name.
3149 ** Fix TLS 1.2 RSA signing in servers.
3150 Before it used the old-style MD5+SHA1 signature, but the TLS
3151 signatures should be normal PKCS#1 signatures. FYI, we use and
3152 require that DigestInfo parameters are present and NULL for TLS 1.2.
3154 ** Add APIs to access X.509 extensions sequentially.
3155 The existing APIs gnutls_x509_crt_get_extension_oid() and
3156 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
3157 inspect the extensions in the order defined by the certificate.
3159 ** Add API to extract signature value from X.509 certificates.
3160 The function is gnutls_x509_crt_get_signature.
3162 ** Fix crash when generating proxy certificates in batch mode.
3163 If you don't specify a proxy policy in batch mode, it will use
3166 ** Add API to print information about X.509 certificates.
3167 The function is gnutls_x509_crt_print.
3169 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
3170 One consequence of this is that the output syntax has changed
3171 slightly. Some more fields are printed.
3175 ** API and ABI modifications:
3176 gnutls_x509_crt_print: ADD
3177 gnutls_certificate_print_formats_t: ADD, new enum.
3178 gnutls_x509_crt_get_signature: ADD.
3179 gnutls_x509_crt_get_extension_data: ADD.
3180 gnutls_x509_crt_get_extension_info: ADD.
3181 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
3182 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
3183 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
3185 * Version 1.7.5 (released 2007-02-06)
3187 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
3190 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
3192 ** Fix --list output for gnutls-cli and gnutls-serv.
3193 Mention TLS1.2, SHA512 etc.
3195 ** Manual contains new section on setting up a test HTTP server.
3196 A server set up following those descriptions are available online via
3197 <http://www.gnutls.org/server.html>.
3199 ** Update of gnulib files.
3201 ** API and ABI modifications:
3202 No changes since last version.
3204 * Version 1.7.4 (released 2007-02-05)
3206 ** Support for RSA signing using SHA-256/384/512.
3207 A new self test "sha2" tries to build a long X.509 certificate chain
3208 testing all new hashes.
3210 ** The gnutls-serv tool now use static DH parameters if none are supplied.
3212 ** Discuss proxy certificates in the manual.
3214 ** Improve bibliographical citations in the manual.
3216 ** Update of gnulib files.
3218 ** Fix certtool template handling of pathLenConstraints.
3219 It now defaults to -1 instead of 0, which causes the field to be
3220 missing unless the template specify it.
3222 ** API and ABI modifications:
3225 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
3228 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
3229 GNUTLS_SIGN_RSA_SHA256,
3230 GNUTLS_SIGN_RSA_SHA384,
3231 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
3233 * Version 1.7.3 (released 2007-02-01)
3235 ** New option to certtool: --generate-proxy.
3236 This will generate a Proxy Certificate from an end entity certificate.
3237 Proxy Certificates are documented in RFC 3820. You will need to
3238 specify the proxy certificate's private key with --load-privkey, the
3239 user certificate with --load-certificate and the private key used to
3240 sign the new proxy certificate with --load-ca-privkey. Certtool will
3241 query for proxy path length and the policy language OID. Currently
3242 only OIDs that have an empty policy are supported (which includes the
3243 two OIDs defined by RFC 3820).
3245 ** Certtool --certificate-info now prints information for Proxy Certificates.
3246 Before the proxy extension was just printed as DER encoded data.
3248 ** New APIs to set proxy subject names and get/set proxy cert extension.
3250 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
3252 ** Added self-test to test for regressions of pathLenConstraint bug.
3253 Incidentally, this also test (some) other regressions or changes in
3254 the output from certtool --certificate-info.
3256 ** When certtool generates CA certificates, pressing enter on the path
3257 ** length constraint query will now remove the field.
3258 Before it set the path length constraint to 0, which is a rather poor
3261 ** Certtool now print times in UTC when printing certificate/CRL info.
3263 ** Add better fix to work around C++ compiler bug on Mac OS X.
3264 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
3266 ** Fix import of ASCII armored OpenPGP keys.
3267 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
3269 ** Update of gnulib files.
3271 ** API and ABI modifications:
3272 gnutls_x509_crt_set_proxy_dn: ADD.
3273 gnutls_x509_crt_set_proxy: ADD.
3274 gnutls_x509_crt_get_proxy: ADD.
3276 * Version 1.7.2 (released 2007-01-14)
3278 ** Certtool now print the value of the pathLenConstraints field for certs.
3280 ** Certtool now query for path length constraints when generating CA certs.
3281 For batch uses, the certtool configuration name is "path_len".
3282 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
3284 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
3285 The new functions gnutls_x509_crt_get_basic_constraints and
3286 gnutls_x509_crt_set_basic_constraints provide a superset of the
3287 functionality in the old gnutls_x509_crt_get_ca_status and
3288 gnutls_x509_crt_set_ca_status (respectively), but the old functions
3289 will continue to be supported.
3291 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
3292 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
3293 OpenCDK release with this patch will be made soon, which should bump
3294 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
3296 ** Certtool --to-p12 can now store more than one certificate in the blob.
3297 Before it could only store one certificate, but now it will read and
3298 store as many certificate there are from the --load-certificate file.
3299 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
3301 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
3302 In particular, the OpenPGP function variables are no longer part of
3303 the exported libgnutls interface, and no header files from
3304 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
3305 were never intended for non-internal purposes, and thus this does not
3306 imply a change in the external API/ABI.
3308 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
3309 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
3311 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
3312 Before these parameters were set to make GnuTLS build under mingw32,
3313 however, they appear to no longer be necessary.
3315 ** A minor fix to the C++ library to make it build.
3316 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
3318 ** Update of gnulib files.
3320 ** API and ABI modifications:
3321 gnutls_x509_crt_get_basic_constraints: ADD.
3322 gnutls_x509_crt_set_basic_constraints: ADD.
3323 cdk_pubkey_to_sexp: ADD (in opencdk).
3324 cdk_seckey_to_sexp: ADD (in opencdk).
3326 * Version 1.7.1 (released 2006-12-28)
3328 ** TLS 1.2 server side fix.
3329 The Certificate Request sent did not contain the list of supported
3330 hashes field, thus violating the protocol. It will now contain an
3331 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
3333 ** TLS 1.2 DSA signature verification fix.
3334 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
3336 ** Fix the list of trusted CAs that server's send to clients.
3337 Before, the list contained issuer DN's instead of subject DN's of the
3338 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
3340 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
3341 Also added a self-test in tests/certificate_set_x509_crl.c to test the
3342 function. Reported by Max Kellermann <max@duempel.org>.
3344 ** Encode UID fields in DN's as DirectoryString.
3345 Before GnuTLS encoded and parsed UID fields as IA5String. This was
3346 incorrect, it should have used DirectoryString. Now it will use
3347 DirectoryString for the UID field, but for backwards compatibility it
3348 will also accept IA5String UID's. Reported by Max Kellermann
3351 ** Improve out-of-sourcedir builds from CVS.
3352 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
3354 ** Bootstrap tools changed.
3355 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
3356 building GnuTLS from CVS. Libtool 1.5.22 is used.
3358 ** Fixed a syntax error in lib/gnutls.asn.
3359 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
3361 ** Added German translation of GnuTLS messages.
3363 ** Update of gnulib files.
3365 ** API and ABI modifications:
3366 No changes since last version.
3368 * Version 1.7.0 (released 2006-11-29)
3370 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
3371 The details is that the protocol priority set by
3372 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
3373 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
3375 ** Preliminary support for TLS 1.2.
3376 The client has been successfully tested against
3377 https://www.mikestoolbox.org:4433/.
3379 ** Anonself test now print a lot of debugging info, including TLS version.
3381 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
3383 ** Update of gnulib files.
3385 ** API and ABI modifications:
3386 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
3388 *** Pulled up from stable 1.6.x branch:
3390 ** Fix ./configure failure with non-GCC compilers.
3391 This fixes the following error message:
3392 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
3393 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
3395 * Version 1.6.3 (released 2007-05-26)
3397 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
3398 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
3399 from the 1.7.x branch, see
3400 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
3402 ** Have PKCS8 parser return better error codes.
3403 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
3404 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
3405 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
3407 ** Fix mem leak for sessions with client authentication via certificates.
3408 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
3409 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
3411 ** Fix building of 'tlsia' self test.
3412 Earlier some gcc are known to build tlsia linking to
3413 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
3414 the build directory, even though command line parameters look OK.
3415 Changing order of some parameters fixes it.
3417 ** API and ABI modifications:
3418 gnutls_x509_crt_get_raw_issuer_dn: ADD.
3419 gnutls_x509_crt_get_raw_dn: ADD.
3421 * Version 1.6.2 (released 2007-04-18)
3423 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
3424 Before, we remove the parameters field, which resulted in a slightly
3425 different DER encoding which in turn caused signature verification
3426 failures of GnuTLS-generated RSA certificates in some other
3427 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
3428 you read, this may or may not be correct, but our new behaviour appear
3429 to be consistent with other widely used implementations.
3431 ** Regenerate the PKIX ASN.1 syntax tree.
3432 For some reason, after changing the ASN.1 type of ldap-UID in the last
3433 release, the generated C file built from the ASN.1 schema was not
3434 refreshed. This can cause problems when reading/writing UID
3435 components inside X.500 Distinguished Names. Reported by devel
3436 <dev001@pas-world.com>.
3438 ** Updated translations.
3440 ** API and ABI modifications:
3441 No changes since last version.
3443 * Version 1.6.1 (released 2006-12-28)
3445 ** Fix the list of trusted CAs that server's send to clients.
3446 Before, the list contained issuer DN's instead of subject DN's of the
3447 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
3449 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
3450 Reported by Max Kellermann <max@duempel.org>.
3452 ** Encode UID fields in DN's as DirectoryString.
3453 Before GnuTLS encoded and parsed UID fields as IA5String. This was
3454 incorrect, it should have used DirectoryString. Now it will use
3455 DirectoryString for the UID field, but for backwards compatibility it
3456 will also accept IA5String UID's. Reported by Max Kellermann
3459 ** Fix ./configure failure with non-GCC compilers.
3460 This fixes the following error message:
3461 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
3462 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
3464 ** API and ABI modifications:
3465 No changes since last version.
3467 * Version 1.6.0 (released 2006-11-17)
3469 ** No changes since 1.5.5.
3470 The major changes compared to the 1.4.x branch are:
3472 *** A GnuTLS C++ library is part of the official distribution.
3473 Currently there are no examples or documentation, but hopefully this
3474 will change. See gnutlsxx.h for the API.
3476 *** Windows is a supported platform.
3477 There are, however, two know bugs. One is related to select() in
3478 command line tools (not, nota bene, in the library), the other is a
3479 problem with libgcrypt that causes delays. Help is needed to resolve
3480 those issues, so we feel we can't delay the release because of this.
3482 *** New APIs for custom push/pull function error reporting.
3483 The new APIs are gnutls_transport_set_errno and
3484 gnutls_transport_set_global_errno. See the release notes for version
3485 1.5.4 for more information.
3487 *** Self tests are run under valgrind, if available. See --disable-valgrind.
3489 * Version 1.5.5 (released 2006-11-16)
3491 ** Correctly bump shared library version after adding new APIs.
3492 This was forgotten in the last release.
3494 ** Fix unsigned vs signed problem in ex-x509-info.c example.
3495 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
3497 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
3499 ** Update of gnulib files.
3501 ** API and ABI modifications:
3502 No changes since last version.
3504 * Version 1.5.4 (released 2006-11-07)
3506 ** New API functions to set errno in push/pull functions.
3507 Under Windows, setting the errno variable in a push/pull replacement
3508 may end up setting the wrong errno variable, and GnuTLS send/recv
3509 functions become confused about the real errno returned from a failed
3510 push/pull function. Therefor, we have added two APIs to set the errno
3511 variable used by GnuTLS. The APIs can also help to keep things
3512 thread-safe, by avoiding potentially global variables. Typically,
3513 instead of setting errno in your push/pull function, you will call one
3514 of these functions. It is recommended to use
3515 gnutls_transport_set_errno, but if you don't have the session variable
3516 easily accessible in the push/pull replacement function, you can use
3517 gnutls_transport_set_global_errno. Suggested by Tim Kosse
3518 <tim.kosse@filezilla-project.org>.
3520 void gnutls_transport_set_errno (gnutls_session_t session, int err);
3521 void gnutls_transport_set_global_errno (int err);
3523 ** When calling `recv' or `send' Windows errors are handled properly.
3524 The Windows recv/send functions doesn't use errno, and GnuTLS now use
3525 WSAGetLastError to access the error condition instead.
3527 ** Several OpenPGP API fixes.
3528 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
3529 important fix is to change the return value of
3530 gnutls_openpgp_privkey_get_pk_algorithm and
3531 gnutls_openpgp_key_get_pk_algorithm from 'int' to
3532 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
3533 compatible with 'int').
3535 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
3536 ** version, try to negotiate the highest version support by the GnuTLS server,
3537 ** instead of the lowest.
3538 Reported by <Pasi.Eronen@nokia.com>.
3540 ** Replace old constructs with use of gnulib modules.
3541 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
3542 the code. If the headers doesn't exist on the target system, gnulib
3543 will make sure its replacement header files are used instead.
3545 ** Fix SOVERSION computation for *.def files.
3546 This fixes build errors similar to "No rule to make target
3547 `libgnutls-`expr', needed by `all-am'." when building for Windows.
3549 ** gnutls_check-version uses strverscmp from gnulib.
3551 ** Update of gnulib files.
3553 ** API and ABI modifications:
3554 gnutls_transport_set_errno: ADD
3555 gnutls_transport_set_global_errno: ADD
3557 * Version 1.5.3 (released 2006-10-26)
3559 ** Add new self-test of RSA-MD5 signature chains.
3560 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
3561 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
3562 and is based on the work by Marc Stevens et al, see
3563 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
3565 ** Re-factor self tests.
3567 ** The include copy of Libtasn1 is updated to version 0.3.7.
3569 ** The included copy of OpenCDK is updated to version 0.5.11.
3571 ** Fix the filename of the *.def file on Windows after library version bump.
3573 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
3574 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
3575 gnulib modules. Earlier we could only use the LGPL'ed module from
3576 gnulib, because two gnulib directories in the same project didn't
3579 ** API and ABI modifications:
3580 No changes since last version.
3582 * Version 1.5.2 (released 2006-10-03)
3584 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
3585 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
3586 shared library version than this version, so you'll have to remove
3587 them and possibly relink your applications. The reason for this is
3588 that no API/ABI changes have been made since the 1.4.x branch, and
3589 that incrementing the shared library version was a mistake. Reported
3590 by Andreas Metzler <ametzler@downhill.at.eu.org>.
3592 ** Fix off-by-one error when computing length to malloc.
3593 The code is used by gnutls_openpgp_add_keyring_file and
3594 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
3595 <agl@imperialviolet.org>.
3597 ** Add version script for the GnuTLS C++ library.
3598 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
3600 ** Fix the C++ compiler detection logic.
3601 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
3603 ** Update of gnulib files.
3605 ** API and ABI modifications:
3606 No changes since last version.
3608 * Version 1.5.1 (released 2006-09-21)
3610 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
3611 ** Crypto 06 rump session attack.
3612 In particular, we check that the digestAlgorithm.parameters field is
3613 missing or empty, to avoid that it can contain "garbage" that may be
3614 used to alter the numeric properties of the signature. See
3615 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
3616 not exactly the same as the problem we fix here). Reported by Yutaka
3617 OIWA <y.oiwa@aist.go.jp>.
3619 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
3620 up to date information.
3622 ** Add self test to test for above flaw.
3624 ** Fix gnutls-cli-debug regarding resume support detection.
3625 Earlier, if the session-id from the server had a length of 0, it would
3626 indicate that the server supports resumption, which isn't the case.
3627 Reported by Kataja Kai <kai.kataja@op.fi>.
3629 ** Fix building of examples on FreeBSD by including netinet/in.h.
3630 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
3632 ** Fix certtool bug that caused the private key to not be loaded when
3633 generating a certificate with --load-request, which in turn triggered
3634 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
3635 by Sascha Ziemann <sascha.ziemann@secunet.com>.
3637 ** gnutls-cli and gnutls-serv works on Windows.
3638 The problem was the select() call that doesn't work on file
3639 descriptors (stdin) on Windows. We borrowed some code from plibc to
3640 solve this. It appears to be somewhat unreliable though.
3642 ** Autoconf 2.60 is now used.
3644 ** API and ABI modifications:
3645 No changes since last version.
3647 * Version 1.5.0 (released 2006-08-13)
3649 ** Change SRP and Cert-Type extensions to match IANA registry.
3651 ** Fixed bug in OpenPGP authentication handshake.
3653 ** Improvements for building under MinGW.
3654 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
3655 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
3656 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
3657 at run-time from ws2_32.dll, and falls back on a simple replacement if
3658 it is not available. Builds the library with -mms-bitfields
3659 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
3660 create *.def files, which are installed.
3662 ** The examples now (conditionally) include config.h and link to gnulib.
3663 No other source changes were necessary, so the examples should
3664 continue to be possible to use stand-alone without any autoconf or
3667 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
3668 You may unconditionally disable it with --disable-cxx. See
3669 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
3672 ** Made command line tool '--version' behave according to GNU Standards.
3673 This enables 'make distcheck' to succeed.
3675 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
3677 ** Make --without-included-libtasn1 work.
3678 Reported by Daniel Black <dragonheart@gentoo.org>.
3680 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.

3703 ** Relax the test that caught signatures that exploit the variant of
3704 ** Bleichenbacher's Crypto 06 rump session attack on our
3705 ** verification logic flaw.
3706 In particular, we now permit the digestAlgorithm.parameters field to
3707 be present but empty, whereas in 1.4.3 we actually checked that the
3710 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
3711 The messages are only printed in debug mode, which is not recommended
3712 for normal use, and thus logging this situation cannot be abused as an
3713 oracle in typical recommended situations.
3715 ** API and ABI modifications:
3716 No changes since last version.
3718 * Version 1.4.3 (released 2006-09-08)
3720 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
3721 ** Crypto 06 rump session attack.
3722 In particular, we check that the digestAlgorithm.parameters field is
3723 empty, to avoid that it can contain "garbage" that may be used to

3744 * Version 1.4.2 (released 2006-08-12)
3746 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
3747 This can happen if you call gnutls_certificate_verify_peers2 and have
3748 a certain mix of local CA certificates and the peer send special
3749 certificates, that together trigger certain behaviour. It is not
3750 known at this point whether the crash can be triggered without the
3751 special local CA certificate, and thus turn this into a remote crash
3752 of clients that verify server certificates when they talk to a server
3753 with the special server certificate. See GNUTLS-SA-2006-2 on
3754 http://www.gnu.org/software/gnutls/security.html for more up to date
3755 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
3757 ** Change SRP and Cert-Type extensions to match IANA registry.
3759 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
3761 ** Make --without-included-libtasn1 work.
3762 Reported by Daniel Black <dragonheart@gentoo.org>.
3764 ** API and ABI modifications:
3765 No changes since last version.
3767 * Version 1.4.1 (released 2006-06-14)
3769 ** Replaced inactive ifdefs to enable openpgp support in test programs.
3771 ** Fixed bug in OpenPGP authentication handshake.
3773 ** Fixed typographical in man pages.
3775 ** Build fixes of the manual.
3777 ** Added Swedish translation.
3779 ** API and ABI modifications:
3780 No changes since last version.
3782 * Version 1.4.0 (released 2006-05-15)
3784 ** Remove GnuTLS 0.8.x compatibility functions.
3786 ** The libgcrypt RNG is initialized in gnutls_global_init().
3788 ** TLS/IA API changes from Emile van Bergen.
3789 A dummy credential structure is not needed now, if you wish to use the
3790 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
3793 ** The self-tests are now run under valgrind, if it is installed.
3795 ** Libtasn1 is updated to 0.3.4, and that version is now required.
3797 ** The command line tools now use getaddrinfo and support IPv6.
3799 ** API and ABI modifications:
3800 _gnutls_x509_get_raw_crt_activation_time,
3801 _gnutls_x509_get_raw_crt_expiration_time: Removed.
3802 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
3803 gnutls_ia_enable: Added.
3805 * Version 1.3.5 (released 2006-03-08)
3807 ** Error messages are now translated using GNU Gettext.
3809 ** The function gnutls_x509_crt_to_xml now return an internal error.
3810 This means that the code to convert X.509 certificates to XML format
3811 does not work any more. The reason is that the function called
3812 libtasn1 internal functions. It seems unclean for libtasn1 to export
3813 the APIs needed here. Instead it would be better to implement XML
3814 support inside libtasn1 properly. If you need this functionality
3815 strongly, please consider looking into implementing this suggested
3816 approach instead. As a workaround, you may also modify lib/x509/xml.c
3817 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
3819 ** Libraries are now built with libtool's -no-undefined.
3820 This helps producing libraries for Windows using mingw32.
3822 ** Doc fixes to explain that gnutls_record_send can block.
3824 ** Libtasn1 0.3.1 or later is now required.
3825 The include copy has been updated too.
3827 ** gnutls-cli can now recognize services and port numbers with the -p option.
3829 ** API and ABI modifications:
3830 No changes since last version.
3832 * Version 1.3.4 (released 2006-02-09)
3834 ** Fix read of out bounds bug in DER parser.
3835 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
3836 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
3837 previous bug fix. The included libtasn1 version in GnuTLS has been
3840 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
3841 longer invalidate a session if the underlying send fails, but it will
3842 prevent future writes. That is to allow reading the already received data.
3843 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
3845 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
3846 gnutls_certificate_set_x509_trust(), that caused memory corruption if
3847 more than one certificates were added. Report and patch by Max Kellermann.
3849 ** Fix build problems of OpenCDK on AIX.
3850 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
3852 ** API and ABI modifications:
3853 No changes since last version.
3855 * Version 1.3.3 (released 2006-01-12)
3857 ** New API to access the TLS master secret.
3858 When possible, you should use the TLS PRF functions instead.
3859 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
3861 ** Improved handling when multiple libraries use GnuTLS at the same time.
3862 Now gnutls_global_init() can be called multiple times, and
3863 gnutls_global_deinit() will only deallocate the structure when it has
3864 been called as many times as gnutls_global_init() was called.
3866 ** Added a self test of TLS resume functionality.
3868 ** Fix crash in TLS resume code, caused by TLS/IA changes.
3870 ** Documentation fixes about thread unsafety, prompted by
3871 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
3872 In particular, gnutls_global_init() and gnutls_global_deinit() are not
3873 thread safe. Careful callers may want to protect the call using a
3874 mutex. The problem could also be ignored, which would cause a memory
3875 leak under rare conditions when two threads invoke the function
3876 roughly at the same time.
3878 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
3880 ** The code was indented again, including the external header files.
3882 ** API and ABI modifications:
3883 New functions to retrieve the master secret value:
3884 gnutls_session_get_master_secret
3886 Add a 'const' keyword to existing API:
3887 gnutls_x509_crq_get_challenge_password
3889 * Version 1.3.2 (released 2005-12-15)
3891 ** GnuTLS now support TLS Inner application (TLS/IA).
3892 This is per draft-funk-tls-inner-application-extension-01. This
3893 functionality is added to libgnutls-extra, so it is licensed under the
3894 GNU General Public License.
3896 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
3897 The PRF is used by some protocols building on TLS, such as EAP-PEAP
3898 and EAP-TTLS. One function to access the raw PRF and one to access
3899 the PRF seeded with the client/server random fields are provided.
3900 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
3902 ** New APIs to acceess the client and server random fields in a session.
3903 These fields can be useful by protocols using TLS. Note that these
3904 fields are typically used as input to the TLS PRF, and if this is your
3905 intended use, you should use the TLS PRF API that use the
3906 client/server random field directly. Suggested by Jouni Malinen
3907 <jkmaline@cc.hut.fi>.
3909 ** Internal type cleanups.
3910 The uint8, uint16, uint32 types have been replaced by uint8_t,
3911 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
3912 correct types on platforms that lack them. The uint type have been
3913 replaced by unsigned.
3915 ** API and ABI modifications:
3916 New functions to invoke the TLS Pseudo-Random-Function (PRF):
3920 New functions to retrieve the session's client and server random values:
3921 gnutls_session_get_server_random
3922 gnutls_session_get_client_random
3924 New function, to perform TLS/IA handshake:
3927 New function to decide whether to do a TLS/IA handshake:

3932 gnutls_ia_free_client_credentials
3933 gnutls_ia_allocate_server_credentials

3941 gnutls_ia_set_server_avp_ptr
3942 gnutls_ia_get_server_avp_ptr
3944 New functions, to toggle TLS/IA application phases:
3945 gnutls_ia_require_inner_phase
3947 New function to mix session keys with inner secret:
3948 gnutls_ia_permute_inner_secret
3950 Low-level API (used internally by gnutls_ia_handshake):
3951 gnutls_ia_endphase_send
3955 New functions that can be used after successful TLS/IA negotiation:
3956 gnutls_ia_generate_challenge
3957 gnutls_ia_extract_inner_secret
3959 Enum type with TLS/IA modes:
3962 Enum type with TLS/IA packet types:
3965 Enum values for TLS/IA alerts:
3966 GNUTLS_A_INNER_APPLICATION_FAILURE
3967 GNUTLS_A_INNER_APPLICATION_VERIFICATION
3969 New error codes, to signal when an application phase has finished:
3970 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
3971 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
3973 New error code to signal TLS/IA verify failure:
3974 GNUTLS_E_IA_VERIFY_FAILED
3976 * Version 1.3.1 (released 2005-12-08)
3978 ** Support for DHE-PSK cipher suites has been added.
3979 This method offers perfect forward secrecy.
3981 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
3982 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
3984 ** Corrected a bug in certtool for 64 bit machines. Reported
3985 by Max Kellermann <max@duempel.org>.
3987 ** New function to set a X.509 private key and certificate pairs, and/or
3988 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
3989 <emile@e-advies.nl>.
3991 The integrity of the PKCS#12 file is protected through a password
3992 based MAC; public-key based signatures for integrity protection are
3993 not supported. PKCS#12 bags may be encrypted using password derived
3994 symmetric keys, public-key based encryption is not supported. The
3995 PKCS#8 keys may be encrypted using passwords. The API use the same
3996 password for all operations. We believe that any more flexibility
3997 create too much complexity that would hurt overall security, but may
3998 add more PKCS#12 related APIs if real-world experience indicate
4001 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
4002 reported by Emile van Bergen <emile@e-advies.nl>.
4003 This will enable "certtool -k -8" to parse those keys.
4005 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
4006 Use "certtool -p -8" and press press enter at the prompt. Earlier,
4007 certtool would have encrypted the key using an empty password.
4009 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
4010 Earlier it would have prompted the user for it, even if --password was
4013 ** Added self test of PKCS#8 parsing.
4014 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
4015 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
4018 ** API and ABI modifications:
4019 New function to set X.509 credentials from a PKCS#12 file:
4020 gnutls_certificate_set_x509_simple_pkcs12_file
4022 New gnutls_kx_algorithm_t enum type:
4025 New API to return session data (basically same as gnutls_session_get_data):
4026 gnutls_session_get_data2
4028 New API to set PSK Diffie-Hellman parameters:
4029 gnutls_psk_set_server_dh_params
4031 * Version 1.3.0 (2005-11-15)
4033 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
4034 This add several new APIs, see below. Read the updated manual for
4035 more information. A new self test "pskself" has been added, that will
4036 test this functionality.
4038 ** The session resumption data are now system independent.
4040 ** The code has been re-indented to conform to the GNU coding style.
4042 ** Removed the RIPEMD ciphersuites.
4044 ** Added a discussion of the internals of gnutls in manual.

4097 * Version 1.2.11 (2006-05-11)
4098 - The function gnutls_x509_crt_to_xml is not supported any more, and
4099 return an internal error. The reason is that the function called
4100 internal libtasn1 functions which are no longer exported from
4102 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
4103 - Updated gnulib compatibility files.
4104 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
4105 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
4106 - API and ABI modifications:
4107 No changes since last version.
4109 * Version 1.2.10 (2006-02-09)
4110 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
4111 <admin@gleg.net>, and debugging help from Protover SSL.
4112 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
4113 The included version has been updated too.
4114 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
4115 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
4116 - Corrected a bug in certtool for 64 bit machines. Reported
4117 by Max Kellermann <max@duempel.org>.
4118 - Corrected bugs in gnutls_certificate_set_x509_crl() and
4119 gnutls_certificate_set_x509_trust(), that caused memory corruption if
4120 more than one certificates were added. Report and patch by Max Kellermann.
4121 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
4122 longer invalidate a session if the underlying send fails, but it will
4123 prevent future writes. That is to allow reading the already received data.
4124 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
4126 * Version 1.2.9 (2005-11-07)
4127 - Documentation was updated and improved.
4128 - RSA-MD2 is now supported for verifying digital signatures.
4129 - Due to cryptographic advances, verifying untrusted X.509
4130 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
4131 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
4132 applications that must remain interoperable, you can use the
4133 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
4134 flags when verifying certificates. Naturally, this is not
4135 recommended default behaviour for applications. To enable the
4136 broken algorithms, call gnutls_certificate_set_verify_flags with the
4137 proper flag, to change the verification mode used by
4138 gnutls_certificate_verify_peers2.
4139 - Make it possible to send empty data through gnutls_record_send,
4140 to align with the send(2) API.
4141 - Some changes in the certificate receiving part of handshake to prevent
4142 some possible errors with non-blocking servers.
4143 - Added numeric version symbols to permit simple CPP-based feature
4144 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
4145 - The (experimental) low-level crypto alternative to libgcrypt used
4146 earlier (Nettle) has been replaced with crypto code from gnulib.
4147 This leads to easier re-use of these components in other projects,
4148 leading to more review and simpler maintenance. The new configure
4149 parameter --with-builtin-crypto replace the old --with-nettle, and
4150 must be used if you wish to enable this functionality. See README
4151 under "Experimental" for more information. Internally, GnuTLS has
4152 been updated to use the new "Generic Crypto" API in gl/gc.h. The
4153 API is similar to the old crypto/gc.h, because the gnulib code were
4154 based on GnuTLS's gc.h.
4155 - Fix compiler warning in the "anonself" self test.
4156 - API and ABI modifications:
4157 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
4158 This doesn't reflect a change in behaviour,
4159 so we don't break backwards compatibility.
4160 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
4161 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
4162 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
4163 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
4165 gnutls_x509_crt_list_verify,
4166 gnutls_x509_crt_verify, or
4167 gnutls_certificate_set_verify_flags.
4168 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
4169 used when broken signature algorithms
4170 is used (currently RSA-MD2/MD5).
4171 LIBGNUTLS_VERSION_MAJOR,
4172 LIBGNUTLS_VERSION_MINOR,
4173 LIBGNUTLS_VERSION_PATCH,
4174 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
4175 version number, can be used for feature existence
4178 * Version 1.2.8 (2005-10-07)
4179 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
4180 - Don't install the auxilliary libexamples library used by the
4181 examples in doc/examples/ on "make install", report and tiny patch
4182 from Thomas Klausner <tk@giga.or.at>.
4183 - If you pass a X.509 CA or PGP trust database to the command line
4184 tool, it will now abort the connection if the server certificate
4185 validation fails. Use the parameter --insecure to continue even
4186 after certificate validation failures. Inspired from discussion
4187 with Alexander Kotelnikov <sacha@myxomop.com>.
4188 - The test for socklen_t has been moved to gnulib.

4276 function prototypes during compile time.
4277 - API and ABI modifications:
4278 No changes since last version. At least not intentional, but due
4279 to the include header changes, there may be inadvertant changes,
4280 please let us know if you find any.

4287 - Added warning to certtool when MD5 is being used for digital
4289 - Optimizations ("-O2 -finline-functions") are not enabled by default,
4290 instead the standard autoconf defaults are used. Use `./configure
4291 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
4292 - Added the option --get-dh-params to certtool, in order to get the
4293 parameters included in the library primes and generators.

4329 gnutls_x509_rdn_get now set *sizeof_buf to the buffer length that is
4330 required, instead of the string length. That is, the value has been
4331 incremented by 1 to account for the terminating zero. Reported by
4332 Martin Lambers <marlam@web.de>.
