259 under the gnutls_ocsp namespace. Currently the functionality provided
260 is to parse and extract information from OCSP requests/responses, to
261 generate OCSP requests and to verify OCSP responses. See the manual
262 for more information. Run ./configure with --disable-ocsp to build
263 GnuTLS without OCSP support.
265 This work was sponsored by Smoothwall <http://smoothwall.net/>.

377 priorities will be used for selection instead of the client's.
379 ** libgnutls: Optimizations in Diffie-Hellman parameters generation
382 ** libgnutls: When session tickets are negotiated and used in a

388 allow listing the ciphersuites enabled in a priority structure.
389 It outputs an index to be used in gnutls_get_cipher_suite_info().
391 ** libgnutls: Optimizations in the elliptic curve code --timing
392 attacks resistant code is only used in ECDSA private key operations.
394 ** doc: man pages for API functions generation was fixed and are
395 now added again in the distribution.

696 keep the data until handshake is over and hash them on request.
697 This uses more memory but eliminates issues with TLS 1.2 and
700 ** libgnutls: Added AES-GCM optimizations using the PCLMULQDQ
701 instruction. Uses Andy Polyakov's assembly code.
703 ** libgnutls: Added gnutls_x509_trust_list_add_named_crt() and
704 gnutls_x509_trust_list_verify_named_crt() that allow having a

1142 ** API and ABI modifications:
1143 gnutls_x509_crt_get_subject_unique_id: ADDED.
1144 gnutls_x509_crt_get_issuer_unique_id: ADDED.
1146 * Version 2.11.1 (released 2010-09-14)
1148 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
1149 to use the libgcrypt back end.
1151 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
1152 backend crypto library.
1154 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
1156 ** libgnutls: Several updates in the buffering internal interface.
1158 ** libgnutls: Is now more liberal in the PEM decoding. That is spaces and
1159 tabs are being skipped.
1161 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
1163 ** libgnutls: The %COMPAT flag now allows larger records that violate the
1166 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
1167 system calls. Applications that depended on it being 1 should explicitly call
1168 gnutls_transport_set_lowat().
1170 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
1171 to ECRYPT II recommendations. Mappings were moved to a single location
1172 and DSA keys are handled differently (since DSA2 allows for 1024,2048
1173 and 3072 keys only).
1175 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1176 gnutls_x509_privkey_import_pkcs8() without a password, if it
1177 is unable to decode the key.
1179 ** libgnutls: HMAC-MD5 no longer used by default.
1181 ** API and ABI modifications:
1182 gnutls_openpgp_privkey_sec_param: ADDED
1183 gnutls_x509_privkey_sec_param: ADDED
1185 * Version 2.11.0 (released 2010-07-22)
1187 ** libgnutls: support scattered write using writev(). This takes
1188 advantage of the new buffering layer and allows queuing of packets
1189 and flushing them. This is currently used for handshake messages
1192 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
1193 alternative locking procedures. By default the system available
1194 locking is used. In *NIX pthreads are used and in windows the
1195 critical section API. This follows a different approach than the
1196 previous versions that depended on libgcrypt initialization. The
1197 locks are now set by default in systems that support it. Programs
1198 that used gcry_control() to set thread locks should insert it into
1200 #if GNUTLS_VERSION_NUMBER <= 0x020b00
1204 ** libgnutls: Added support for reading DN from EV-certificates.
1206 jurisdictionOfIncorporationLocalityName,
1207 jurisdictionOfIncorporationStateOrProvinceName,
1208 jurisdictionOfIncorporationCountryName
1210 ** libgnutls: Added support for DSA signing/verifying with bit
1213 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
1214 has to be called to register any required md5 handlers.
1216 ** libgnutls: Internal buffering code was replaced by simpler
1217 code contributed by Jonathan Bastien-Filiatrault.
1219 ** libgnutls: Internal API for extensions augmented to allow
1220 safe storing and loading of data on resumption. This allows writing
1221 self-contained extensions (when possible). As a side effect
1222 the OPRFI extension was removed.
1224 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
1226 ** libgnutls: Added PKCS #11 support and an API to access objects in
1227 gnutls/pkcs11.h. Currently certificates and public keys can be
1228 imported from tokens, and operations can be performed on private keys.
1230 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
1232 ** libgnutls: Added initial support for the nettle library. It uses
1233 the system's random generator for seeding. That is /dev/urandom in Linux,
1234 system calls in Win32 and EGD on other systems.
1236 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
1237 works even when resuming a session.
1239 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
1240 similar gnutls_certificate_set_server_retrieve_function() and
1241 gnutls_certificate_set_client_retrieve_function(). In addition it support
1242 PKCS #11 private keys.
1244 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
1245 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
1247 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
1248 sizes for private keys using a human understandable scale.
1250 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
1251 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
1252 --pkcs11-delete-url, --pkcs11-write
1254 certtool: The --pkcs-cipher is taken into account when generating a
1255 private key. The default cipher used now is aes-128. The old behavior can
1256 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1258 certtool: Added --certificate-pubkey to print the public key of the
1261 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
1262 can now accept a PKCS #11 URL in addition to a file. This will allow for
1263 example to use the Gnome-keyring trusted certificate list to verify
1264 connections using a url such as:
1265 pkcs11:token=Root%20CA%20Certificates;serial=1%3AROOTS%3ADEFAULT;model=1%2E0;manufacturer=Gnome%20Keyring

1346 * Version 2.10.1 (released 2010-07-25)
1348 ** libgnutls: Added support for broken certificates that indicate RSA
1351 ** gnutls-cli: Allow verification using V1 CAs.
1353 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1354 gnutls_x509_privkey_import_pkcs8() without a password, if it
1355 is unable to decode the key.
1357 ** libgnutls: Correctly deinitialize crypto API functions to prevent
1358 a memory leak. Reported by Mads Kiilerich.
1360 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
1361 issue a warning, that the output key might not be working everywhere.
1363 ** certtool: The --pkcs-cipher is taken into account when generating a
1364 private key. The default cipher used now is aes-128. The old behavior
1365 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1367 ** API and ABI modifications:
1368 No changes since last version.
1370 * Version 2.10.0 (released 2010-06-25)
1372 ** API and ABI modifications:
1373 No changes since last version.
1375 * Version 2.9.12 (released 2010-06-17)
1377 ** gnutls-cli: Make --starttls work again.
1378 Problem introduced in patch to use read() instead of fgets() committed
1381 ** API and ABI modifications:
1382 No changes since last version.
1384 * Version 2.9.11 (released 2010-06-07)
1386 ** libgnutls: Removed two APIs related to safe renegotiation.
1387 Use priority strings instead. The APIs were
1388 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
1389 (Remember that we don't promise ABI stability during development
1390 series, so this doesn't cause an shared library ABI increment.)
1392 ** tests: More self testing of safe renegotiation extension.
1393 See tests/safe-renegotiation/README for more information.
1395 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
1397 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
1399 ** API and ABI modifications:
1400 gnutls_safe_negotiation_set_initial: REMOVED.
1401 gnutls_safe_renegotiation_set: REMOVED.
1403 * Version 2.9.10 (released 2010-04-22)
1405 ** libgnutls: Time verification extended to trusted certificate list.
1406 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
1409 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
1410 Based on patch by Pavan Konjarla. Adds new constant
1411 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
1413 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
1414 Solves the issue discussed in:
1415 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
1416 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
1417 Note that to allow connecting to unpatched servers the full protection
1418 is only enabled if the priority string %SAFE_RENEGOTIATION is
1419 specified. You can check whether protection is in place by querying
1420 gnutls_safe_renegotiation_status(). New error codes
1421 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
1422 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
1424 ** libgnutls: When checking openpgp self signature also check the signatures
1426 Ilari Liusvaara noticed and reported the issue and provided test
1429 ** libgnutls: Added cryptodev support (/dev/crypto).
1430 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
1431 benchmark utility for AES. Adds new error codes
1432 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
1434 ** libgnutls: Exported API to access encryption and hash algorithms.
1435 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
1436 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
1437 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
1438 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
1439 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
1440 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
1441 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
1443 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
1444 verification of certificate upon receipt rather than waiting until the
1445 end of the handshake.
1447 ** libgnutls: Don't send alerts during handshake.
1448 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
1450 ** certtool: Corrected two issues that affected certificate request generation.
1451 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
1452 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
1453 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
1454 those parameters there since other implementations don't do either and having
1455 them does not seem to offer anything (anyway you need the signer's certificate
1456 to verify thus public key will be available). Found thanks to Boyan Kasarov.
1457 This however has the side-effect that public key IDs shown by certtool are
1458 now different than previous gnutls releases.
1459 (3) the option --pgp-certificate-info will verify self signatures
1461 ** certtool: Allow exporting of Certificate requests on DER format.
1463 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
1465 ** gnutls-cli: Handle reading binary data from server.

1528 No changes since last version.
1530 * Version 2.9.8 (released 2009-11-05)
1532 ** libgnutls: Fix for memory leaks on interrupted handshake.
1533 Reported by Tang Tong.
1535 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
1536 ** extension and certificate verify field.
1537 This requires changes for TLS 1.2 servers and clients that use
1538 callbacks for certificate retrieval. They are now required to check
1539 with gnutls_sign_algorithm_get_requested() whether the certificate
1540 they send complies with the peer's preferences in signature
1543 ** libgnutls: In server side when resuming a session do not overwrite the
1544 ** initial session data with the resumed session data.
1546 ** libgnutls: Added support for AES-128, AES-192 and AES-256 in PKCS #8
1548 This affects also PKCS #12 encoded files. This adds the following new
1549 enums: GNUTLS_CIPHER_AES_192_CBC, GNUTLS_PKCS_USE_PBES2_AES_128,
1550 GNUTLS_PKCS_USE_PBES2_AES_192, GNUTLS_PKCS_USE_PBES2_AES_256.
1552 ** libgnutls: Fix PKCS#12 encoding.
1553 The error you would get was "The OID is not supported.". Problem
1554 introduced for the v2.8.x branch in 2.7.6.
1556 ** certtool: Added the --pkcs-cipher option.
1557 To explicitely specify the encryption algorithm to use.
1559 ** tests: Added "pkcs12_encode" self-test to check PKCS#12 functions.
1561 ** tests: Fix time bomb in chainverify self-test.
1562 Reported by Andreas Metzler <ametzler@downhill.at.eu.org> in
1563 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3925>.
1565 ** tests: Fix expired cert in chainverify self-test.
1567 ** i18n: Vietnamese translation updated.

1616 The new supported ciphersuites are AES-128/256 in CBC mode with
1617 ANON-DH/RSA/DHE-DSS/DHE-RSA. Contributed by Daiki Ueno. Further,
1618 SHA-256 is now the preferred default MAC (however it is only used with
1621 ** libgnutls: Make OpenPGP hostname checking work again.
1622 The patch to resolve the X.509 CN/SAN issue accidentally broken
1623 OpenPGP hostname comparison.
1625 ** libgnutls: When printing X.509 certificates, handle XMPP SANs better.
1626 Reported by Howard Chu <hyc@symas.com> in
1627 <https://savannah.gnu.org/support/?106975>.
1629 ** Fix use of deprecated types internally.
1630 Use of deprecated types in GnuTLS from now on will lead to a compile
1631 error, to prevent this from happening again.
1633 ** API and ABI modifications:
1634 No changes since last version.
1636 * Version 2.9.3 (released 2009-08-19)
1638 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
1639 The new APIs are gnutls_session_ticket_enable_client,
1640 gnutls_session_ticket_enable_server, and
1641 gnutls_session_ticket_key_generate.
1643 ** gnutls-cli, gnutls-serv: New parameter --noticket to disable TLS tickets.
1645 ** API and ABI modifications:
1646 gnutls_session_ticket_key_generate: ADDED.
1647 gnutls_session_ticket_enable_client: ADDED.
1648 gnutls_session_ticket_enable_server: ADDED.
1650 * Version 2.9.2 (released 2009-08-14)
1652 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
1653 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
1654 into 1) not printing the entire CN/SAN field value when printing a
1655 certificate and 2) cause incorrect positive matches when matching a
1656 hostname against a certificate. Some CAs apparently have poor
1657 checking of CN/SAN values and issue these (arguable invalid)
1658 certificates. Combined, this can be used by attackers to become a
1659 MITM on server-authenticated TLS sessions. The problem is mitigated
1660 since attackers needs to get one certificate per site they want to
1661 attack, and the attacker reveals his tracks by applying for a
1662 certificate at the CA. It does not apply to client authenticated TLS
1663 sessions. Research presented independently by Dan Kaminsky and Moxie
1664 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
1665 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
1667 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
1668 The function may fail incorrectly when an earlier certificate was
1669 imported to the same gnutls_x509_crt_t structure.
1671 ** minitasn1: Internal copy updated to libtasn1 v2.3.
1673 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.

1685 The encryption key derived from the password was incorrect for (on
1686 average) 1 in every 128 input for random inputs. Reported by "Kukosa,

1702 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
1703 Before we required that the runtime library used the same (or more
1704 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
1705 that the runtime usage is above the minimum required. Reported by
1706 Marco d'Itri <md@linux.it> via Andreas Metzler
1707 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.
1709 ** tests: Added new self-test pkcs12_s2k_pem to detect MPI bit length error.
1711 ** tests: Improved test vectors in self-test pkcs12_s2k.

1745 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
1746 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
1748 Note: As a side effect of this change, the "public key identifier"
1749 value computed for a certificate using this version of GnuTLS will be
1750 different from values computed using earlier versions of GnuTLS.
1752 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
1753 ** optional SignatureAlgorithm parameter field.
1754 VeriSign rejected these CSRs. They are stricly speaking not needed
1755 since you need the signer's certificate to verify the certificate
1756 signature anyway. Reported by Wilankar Trupti

2016 No offically supported interfaces have been modified or removed. The
2017 library should be completely backwards compatible on both the source
2020 The shared library no longer exports some symbols that have never been
2021 officially supported, i.e., not mentioned in any of the header files.
2027 Normally when symbols are removed, the shared library version has to
2028 be incremented. This leads to a significant cost for everyone using
2029 the library. Because none of the above symbols have ever been
2030 intended for use by well-behaved applications, we decided that the it
2031 would be better for those applications to pay the price rather than
2032 incurring problems on the majority of applications.
2034 If it turns out that applications have been using unofficial
2035 interfaces, we will need to release a follow-on release on the v2.8
2036 branch to exports additional interfaces. However, initial testing
2037 suggests that few if any applications have been using any of the
2040 Although not a new change compared to 2.6.x, we'd like to remind you
2041 interfaces have been modified so that X.509 chain verification now
2042 also checks activation/expiration times on certificates. The affected
2045 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2046 gnutls_certificate_verify_peers: Likewise.
2047 gnutls_certificate_verify_peers2: Likewise.
2048 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
2049 GNUTLS_CERT_EXPIRED: ADDED.
2050 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2052 This change in behaviour was made during the GnuTLS 2.6.x cycle, and
2053 we gave our rationale for it in earlier release notes.
2055 The following symbols have been added to the library:

2213 ** libgnutls: Fix DSA key generation.
2214 Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2216 ** libgnutls: Check expiration/activation time on untrusted certificates.
2217 Merged from stable branch. Reported by Romain Francoise
2218 <romain@orebokech.com>. This changes the semantics of
2219 gnutls_x509_crt_list_verify, which in turn is used by
2220 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
2221 We add two new gnutls_certificate_status_t codes for reporting the new
2222 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
2223 We also add a new gnutls_certificate_verify_flags flag,
2224 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2225 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
2227 ** lib: Linker version scripts reduces number of exported symbols.
2228 The linker version script now lists all exported ABIs explicitly, to
2229 avoid accidentally exporting unintended functions. Compared to
2230 before, most symbols beginning with _gnutls* are no longer exported.
2231 These functions have never been intended for use by applications, and
2232 there were no prototypes for these function in the public header
2233 files. Thus we believe it is possible to do this without incrementing
2234 the library ABI version which normally has to be done when removing an
2237 ** lib: Limit exported symbols on systems without LD linker scripts.
2238 Before all symbols were exported. Now we limit the exported symbols
2239 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
2240 _gnutls*. This is a superset of the actual supported ABI, but still
2241 an improvement compared to before. This is implemented using Libtool
2242 -export-symbols-regex. It is more portable than linker version
2245 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
2246 This should have been done in the last release.
2248 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
2249 Reported by Peter Hendrickson <pdh@wiredyne.com> in
2250 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
2252 ** doc: Improved sections for the info manual.
2253 We now follow the advice given by the texinfo manual on which
2254 directory categories to use. In particular, libgnutls moved from the
2255 'GNU Libraries' section to the 'Software libraries' and the command
2256 line tools moved from 'Network Applications' to 'System
2259 ** API and ABI modifications:
2260 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2261 gnutls_certificate_verify_peers: Likewise.
2262 gnutls_certificate_verify_peers2: Likewise.
2263 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
2264 GNUTLS_CERT_EXPIRED: ADDED.
2265 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2267 * Version 2.7.7 (released 2009-04-20)
2269 ** libgnutls: Applied patch by Cedric Bail to add functions
2270 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
2272 ** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.

2274 <http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3467>.
2276 ** minitasn1: Internal copy updated to libtasn1 v1.8.
2277 GnuTLS is also internally ready to be used with libtasn1 v2.0.
2279 ** doc: Fix build failure of errcodes/printlist.
2280 Reported by Roman Bogorodskiy <novel@FreeBSD.org> in
2281 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3435>.
2283 ** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
2284 It is currently only used by the core library. This will enable a new
2285 domain 'gnutls' for translations of the command line tools.
2287 ** Corrected possible memory corruption on signature verification failure.
2288 Reported by Miroslav Kratochvil <exa.exa@gmail.com>
2290 ** API and ABI modifications:
2291 gnutls_x509_crt_verify_hash: ADDED
2292 gnutls_x509_crt_get_verify_algorithm: ADDED
2294 * Version 2.7.6 (released 2009-02-27)
2296 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
2297 This applies both to generating certificates and certificate requests.
2299 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
2301 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
2302 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
2303 be used for chain verification.
2305 ** gnutls-serv: No longer disable MAC padding by default.
2306 Use --priority NORMAL:%COMPAT to disable MAC padding again.
2308 ** gnutls-cli: Certificate information output format changed.
2309 The tool now uses libgnutls' functions to print certificate
2310 information. This avoids code duplication.
2312 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
2313 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
2314 They can be used to override the default certificate chain validation
2317 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2318 specify the client hello message record version. Used to overcome buggy
2319 TLS servers. Report by Martin von Gagern.
2321 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
2323 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
2325 ** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
2327 ** API and ABI modifications:
2328 No changes since last version.
2330 * Version 2.7.5 (released 2009-02-06)
2332 ** libgnutls: Accept chains where intermediary certs are trusted.
2333 Before GnuTLS needed to validate the entire chain back to a
2334 self-signed certificate. GnuTLS will now stop looking when it has
2335 found an intermediary trusted certificate. The new behaviour is
2336 useful when chains, for example, contains a top-level CA, an
2337 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2338 To avoid chain validation errors due to the RSA-MD5 cert, you can
2339 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2340 The signature on trusted certificates are not checked, so the chain
2341 has a chance to validate correctly. Reported by "Douglas E. Engert"
2342 <deengert@anl.gov> in
2343 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2345 ** libgnutls: result_size in gnutls_hex_encode now holds
2346 the size of the result. Report by John Brooks <special@dereferenced.net>.
2348 ** libgnutls: gnutls_handshake when sending client hello during a
2349 rehandshake, will not offer a version number larger than the current.
2350 Reported by Tristan Hill <stan@saticed.me.uk>.
2352 ** libgnutls: Permit V1 Certificate Authorities properly.
2353 Before they were mistakenly rejected even though
2354 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2355 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2356 "Douglas E. Engert" <deengert@anl.gov> in
2357 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2359 ** API and ABI modifications:
2360 No changes since last version.
2362 * Version 2.7.4 (released 2009-01-07)
2364 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2365 This is a bugfix -- the previous attempt to do this from internal x509
2366 certificate verification procedures did not return the correct value
2367 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2368 <dkg@fifthhorseman.net> in
2369 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2370 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
2371 Gillmor <dkg@fifthhorseman.net>.
2373 ** libgnutls: New interface to get key id for certificate requests.
2374 Patch from David MarÃn Carreño <davefx@gmail.com> in
2375 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
2377 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
2379 ** certtool: --verify-chain now prints results of using library verification.
2380 Earlier, certtool --verify-chain used its own validation algorithm
2381 which wasn't guaranteed to give the same result as the libgnutls
2382 internal validation algorithm. Now this command print a new final
2383 line with header 'Chain verification output:' that contains the result
2384 from using the internal verification algorithm on the same chain.
2386 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
2388 ** API and ABI modifications:
2389 gnutls_x509_crq_get_key_id: ADDED.
2391 * Version 2.7.3 (released 2008-12-10)
2393 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
2394 Reported by Michael Kiefer <Michael-Kiefer@web.de> in

2396 Andreas Metzler <ametzler@downhill.at.eu.org> in
2397 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
2399 ** libgnutls: Libgcrypt initialization changed.
2400 If libgcrypt has not already been initialized, GnuTLS will now
2401 initialize libgcrypt with disabled secure memory. Initialize
2402 libgcrypt explicitly in your application if you want to enable secure
2403 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
2404 allocation functions, which doesn't use secure memory, so there is no
2405 real change in behaviour.
2407 ** libgnutls: Fix memory leak in PSK authentication.
2408 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
2409 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
2411 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
2413 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
2414 It needs to be invoked before libgcrypt is initialized.
2416 ** gnutls-cli: Return non-zero exit code on error conditions.
2418 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
2420 ** tests: Added chainverify self-test that tests X.509 chain verifications.
2422 ** API and ABI modifications:
2423 No changes since last version.
2425 * Version 2.7.2 (released 2008-11-18)
2427 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
2428 The flaw makes it possible for man in the middle attackers (i.e.,
2429 active attackers) to assume any name and trick GnuTLS clients into
2430 trusting that name. Thanks for report and analysis from Martin von
2431 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
2433 Any updates with more details about this vulnerability will be added
2434 to <http://www.gnu.org/software/gnutls/security.html>
2436 ** libgnutls: Fix namespace issue with version symbols.
2437 The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
2438 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
2439 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
2440 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
2441 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
2442 work but are deprecated.
2444 ** certtool: allow setting arbitrary key purpose object identifiers.
2446 ** libgnutls: Fix detection of C99 macros, to make debug logging work again.
2448 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
2449 Reported by Kevin Quick <quick@sparq.org> in
2450 <https://savannah.gnu.org/support/index.php?106454>.

2455 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3194>.
2457 ** libgnutls: Change detection of when to use a linker version script.
2458 Use --enable-ld-version-script or --disable-ld-version-script to
2459 override auto-detection logic.
2461 ** doc: Change license on the manual to GFDLv1.3+.
2463 ** doc: GTK-DOC fixes for new splitted configuration system.

2493 ** certtool: print a PKCS #8 key even if it is not encrypted.
2495 ** Old libgnutls.m4 and libgnutls-config scripts removed.
2496 Please use pkg-config instead.
2498 ** Configuration system modified.
2499 There is now a configure script in lib/ and libextra/ as well, because
2500 gnulib works better with a config.h per gnulib directory.

2528 Patch by ludo@gnu.org (Ludovic Courtès).
2530 ** Changed detection of libtasn1 and libgcrypt to avoid depending on *-config.
2531 We now require a libgcrypt that has Camellia constants declared in
2532 gcrypt.h, which means v1.3.0 or later.

2563 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
2564 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
2566 ** libgnutls: Fix DSA key generation.
2567 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
2568 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
2569 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2571 ** libgnutls: Check expiration/activation time on untrusted certificates.
2572 Reported by Romain Francoise <romain@orebokech.com>. Before the
2573 library did not check activation/expiration times on certificates, and
2574 was documented as not doing so. We have realized that many
2575 applications that use libgnutls, including gnutls-cli, fail to perform
2576 proper checks. Implementing similar logic in all applications leads
2577 to code duplication. Hence, we decided to check whether the current
2578 time (as reported by the time function) is within the
2579 activation/expiration period of certificates when verifying untrusted
2582 This changes the semantics of gnutls_x509_crt_list_verify, which in
2583 turn is used by gnutls_certificate_verify_peers and
2584 gnutls_certificate_verify_peers2. We add two new
2585 gnutls_certificate_status_t codes for reporting the new error
2586 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
2587 add a new gnutls_certificate_verify_flags flag,
2588 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2591 More details about the vulnerabilities will be posted at

2594 ** gnutls-cli, gnutls-cli-debug: Fix AIX build problem.
2595 Reported by LAUPRETRE François (P) <francois.laupretre@ratp.fr> in
2596 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3468>.
2598 ** tests: Fix linking of tests/openpgp/keyring self-test.
2599 Reported by Daniel Black in <https://savannah.gnu.org/support/?106543>.
2601 ** API and ABI modifications:
2602 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2603 gnutls_certificate_verify_peers: Likewise.
2604 gnutls_certificate_verify_peers2: Likewise.
2605 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
2606 GNUTLS_CERT_EXPIRED: ADDED.
2607 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2609 * Version 2.6.5 (released 2009-04-11)
2611 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2612 specify the client hello message record version. Used to overcome buggy
2613 TLS servers. Report by Martin von Gagern.
2615 ** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
2616 Libtasn1 0.3.4 or later is required. This is to align with the
2617 upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.
2619 ** API and ABI modifications:
2620 No changes since last version.
2622 * Version 2.6.4 (released 2009-02-06)
2624 ** libgnutls: Accept chains where intermediary certs are trusted.
2625 Before GnuTLS needed to validate the entire chain back to a
2626 self-signed certificate. GnuTLS will now stop looking when it has
2627 found an intermediary trusted certificate. The new behaviour is
2628 useful when chains, for example, contains a top-level CA, an
2629 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2630 To avoid chain validation errors due to the RSA-MD5 cert, you can
2631 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2632 The signature on trusted certificates are not checked, so the chain
2633 has a chance to validate correctly. Reported by "Douglas E. Engert"
2634 <deengert@anl.gov> in
2635 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2637 ** libgnutls: result_size in gnutls_hex_encode now holds
2638 the size of the result. Report by John Brooks <special@dereferenced.net>.
2640 ** libgnutls: gnutls_handshake when sending client hello during a
2641 rehandshake, will not offer a version number larger than the current.
2642 Reported by Tristan Hill <stan@saticed.me.uk>.
2644 ** libgnutls: Permit V1 Certificate Authorities properly.
2645 Before they were mistakenly rejected even though
2646 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2647 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2648 "Douglas E. Engert" <deengert@anl.gov> in
2649 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2651 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2652 This is a bugfix -- the previous attempt to do this from internal x509
2653 certificate verification procedures did not return the correct value
2654 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2655 <dkg@fifthhorseman.net> in
2656 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2657 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn

2676 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
2677 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
2679 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
2680 It needs to be invoked before libgcrypt is initialized.
2682 ** gnutls-cli: Return non-zero exit code on error conditions.
2684 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
2686 ** API and ABI modifications:
2687 No changes since last version.
2689 * Version 2.6.2 (released 2008-11-12)
2691 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
2692 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
2693 problem for certificate chains that contained just one self-signed
2694 certificate. Reported by Michael Meskes <meskes@debian.org> in
2695 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505279>.
2697 ** API and ABI modifications:
2698 No changes since last version.
2700 * Version 2.6.1 (released 2008-11-10)
2702 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
2703 The flaw makes it possible for man in the middle attackers (i.e.,
2704 active attackers) to assume any name and trick GnuTLS clients into
2705 trusting that name. Thanks for report and analysis from Martin von
2706 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
2708 Any updates with more details about this vulnerability will be added
2709 to <http://www.gnu.org/software/gnutls/security.html>
2711 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.

2716 Fixes problem when linking certtool statically. Tiny patch from Aaron
2717 Ucko <ucko@ncbi.nlm.nih.gov>.
2719 ** libgnutls-openssl: Fix patch against X509_get_issuer_name.
2720 It incorrectly returned the subject DN instead of issuer DN in v2.6.0.
2721 Thanks to Thomas Viehmann <tv@beamnet.de> for report.
2723 ** certtool: Print a PKCS #8 key even if it is not encrypted.
2725 ** tests: Make tests compile when using internal libtasn1.
2726 Patch by ludo@gnu.org (Ludovic Courtès).
2728 ** API and ABI modifications:
2729 No changes since last version.
2731 * Version 2.6.0 (released 2008-10-06)
2733 ** libgnutls: Correct printing and parsing of IPv6 addresses.
2735 ** libgnutls-openssl: fix out of bounds access.
2736 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
2737 from Thomas Viehmann <tv@beamnet.de>.
2739 ** certtool: Use inet_pton for parsing IPv6 addresses.
2741 ** Major changes compared to the v2.4 branch:
2743 *** Added API to replace and update the crypto backend.
2745 *** certtool: can add several subject alternative names via template file.
2747 *** opencdk: Parse (but not decrypt) encrypted secret keys.
2749 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
2750 either set or append alternative names. It can also handle binary structures
2751 such as IP addresses.
2753 *** libgnutls: New function to set minimum acceptable SRP bits.
2754 The function is gnutls_srp_set_prime_bits.
2756 *** libgnutls: Add interface to deal with public key and signature algorithms.
2757 The functions are called gnutls_pk_list, gnutls_pk_get_id,
2758 gnutls_sign_list, and gnutls_sign_get_id.
2760 *** libgnutls: New interfaces to get name of public key and signing algorithms.
2761 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
2763 *** libgnutls: New API to get a string corresponding to a error symbol.
2764 The function is gnutls_strerror_name.
2766 *** libgnutls: New API to set the public parameters in a certificate request
2767 *** from a private key.
2768 The function is gnutls_x509_crq_set_key_rsa_raw.
2770 *** libgnutls: New API to set a callback to extract TLS Finished data.
2771 The function to register is gnutls_session_set_finished_function and
2772 it takes a callback of the gnutls_finished_callback_func type.
2774 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
2776 *** libgnutls: New interface to register a new TLS extension handler.
2777 The new function gnutls_ext_register can be used to register handlers
2778 for specific TLS extension types. The callback functions have the new
2779 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
2780 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
2783 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
2784 The function is gnutls_register_md5_handler. When libgcrypt is in
2785 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
2788 *** API/ABI changes in GnuTLS 2.6
2789 No functions have been removed or modified. The library should be
2790 fully backwards compatible on both the source and binary level.
2792 A new header file <gnutls/crypto.h> have been added. It contains
2793 definitions related to replacing the internal crypto functionality.
2794 All definitions and the header itself is experimental but supported.
2796 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
2797 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
2798 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
2800 The following functions have been added to libgnutls:
2804 gnutls_crypto_bigint_register2
2805 gnutls_crypto_cipher_register2
2806 gnutls_crypto_digest_register2
2807 gnutls_crypto_mac_register2

2840 Report and patch by Jonathan Manktelow.
2842 ** libgnutls: crypto.h gnutls_pk_params_st changes allocation strategy.
2843 The parameters are now allocated in the structure itself.
2845 ** doc: Texinfo HTML manual uses a stylesheet to improve readability.
2847 ** tests: Scripts now use EXEEXT properly.
2848 Modern libtool doesn't create wrapper script, so the self tests need
2849 to invoke certtool.exe under MinGW32+Wine.
2851 ** Uses autoconf 2.63, automake 1.10.1, libtool 2.2.6a.
2852 Automake warnings are now also enabled.
2854 ** API and ABI modifications:
2855 gnutls_pk_params_st: MODIFIED
2857 * Version 2.5.8 (released 2008-09-21)
2859 ** certtool: updated so it can add several subject alternative names using
2862 ** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
2863 either set or append alternative names. It can also handle binary structures
2864 such as IP addresses.
2866 ** libgnutls: Fix crash in hashing code when using non-libgcrypt handlers.
2868 ** libgnutls: New function to set minimum acceptable SRP bits.
2869 The function is gnutls_srp_set_prime_bits. Tiny patch by Kevin Quick
2870 <quick@sparq.org> in <https://savannah.gnu.org/support/index.php?106454>.
2872 ** libgnutls: Check for overflows in gnutls_calloc and gnutls_secure_calloc.
2873 Also fix overflows in calls to those functions. Reported by Werner
2874 Koch <wk@gnupg.org>.

2942 * Version 2.5.5 (released 2008-08-29)
2944 ** libgnutls: New API to get a string corresponding to a error symbol.
2945 The function is gnutls_strerror_name.
2947 ** libgnutls: Fix include paths so that building with internal libtasn1 works.
2948 Reported by "jth.net ApS" <info@jth.net>.
2950 ** libgnutls: Fix segmentation fault when generating private keys.
2951 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
2953 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
2954 The code has not worked since v0.9.0 and apparently nobody has missed
2955 it, so we decided to remove the code rather than fix it. If you have
2956 old certificate chains stored in PKCS#7 format, you can convert them
2957 to a list of PEM certificates by using 'certtool --p7-info'. Reported
2958 by Christian Grothoff <christian@grothoff.org>.
2960 ** opencdk: Parse (but not decrypt) encrypted secret keys.
2961 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
2963 ** libgnutls: Fix many warnings.
2965 ** Included copy of libtasn1 is upgraded to version 1.5.
2967 ** Add French translation, thanks to Nicolas Provost.
2969 ** API and ABI modifications:
2970 gnutls_strerror_name: ADDED
2972 * Version 2.5.4 (released 2008-08-19)
2974 ** Fix secure memory initialization of libgcrypt.
2975 Reported by Joe Orton <joe@manyfish.co.uk> in
2976 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2992>.
2979 Reference to NIST SP 800-57 in the manual on key size recommendations.
2980 Added 'Since:' tags to new APIs for gtk-doc.
2982 ** API and ABI modifications:
2983 No changes since last version.
2985 * Version 2.5.3 (released 2008-08-14)
2987 ** libgnutls: New API to set the public parameters in a certificate request
2988 ** from a private key.
2989 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
2990 discussion with "Zach C." <fxchip@gmail.com>.
2992 ** libgnutls: New API to set a callback to extract TLS Finished data.
2993 The function to register is gnutls_session_set_finished_function and
2994 it takes a callback of the gnutls_finished_callback_func type.
2996 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
2997 Reported in <https://savannah.gnu.org/support/?106453>.
2999 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
3000 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
3001 names are mapped to the new names in compat.h. These mappings will
3002 likely be removed more quickly than other mappings in that file due to
3003 the namespace violation.
3005 ** libgnutlsxx: Make it build when SRP is disabled.
3007 ** doc: Add doxygen files in doc/doxygen/.
3009 ** API and ABI modifications:
3010 gnutls_x509_crq_set_key_rsa_raw: ADDED

3013 GNUTLS_MASTER_SIZE: ADDED
3014 GNUTLS_RANDOM_SIZE: ADDED
3015 TLS_MASTER_SIZE: DEPRECATED
3016 TLS_RANDOM_SIZE: DEPRECATED
3018 * Version 2.5.2 (released 2008-07-08)
3020 ** libgnutls: Fix bug in gnutls_dh_params_generate2.
3021 The prime and generator was swapped.
3023 ** libgnutls: New interface to register a new TLS extension handler.
3024 The new function gnutls_ext_register can be used to register handlers
3025 for specific TLS extension types. The callback functions have the new
3026 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
3027 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
3030 ** Move more code for TLS/IA extension from libgnutls to libgnutls-extra.
3031 This was made possible by using the new gnutls_ext_register interface.
3032 The TLS/IA functionality has only been supported through the
3033 libgnutls-extra library, so it makes sense for the code to belong
3036 ** API and ABI modifications:
3037 gnutls_ext_recv_func: ADDED
3038 gnutls_ext_send_func: ADDED
3039 gnutls_ext_parse_type_t: ADDED
3040 gnutls_ext_register: ADDED
3042 * Version 2.5.1 (released 2008-07-02)
3046 ** API and ABI modifications:
3047 No changes since last version.
3049 * Version 2.5.0 (released 2008-07-02)
3051 ** Port fixes from v2.4.1 release, see below.
3053 ** Added API to replace and update the crypto backend.
3054 The header gnutls/crypto.h is now officially supported, and declares
3057 ** Rewritten opencdk crypto backend, to use the gnutls internal one.
3059 ** Update gnulib and translations.
3060 The gnulib gc crypto code has been removed since it was never finished
3061 and is no longer even used. An internal non-libgcrypt crypto
3062 implementation may be added in the future, but we'll decide that later
3065 ** API and ABI modifications:
3066 gnutls_crypto_bigint_register2: ADDED.
3067 gnutls_crypto_cipher_register2: ADDED.

3074 gnutls_crypto_single_mac_register2: ADDED.
3076 * Version 2.4.3 (released 2009-02-06)
3078 ** libgnutls: Accept chains where intermediary certs are trusted.
3079 Before GnuTLS needed to validate the entire chain back to a
3080 self-signed certificate. GnuTLS will now stop looking when it has
3081 found an intermediary trusted certificate. The new behaviour is
3082 useful when chains, for example, contains a top-level CA, an
3083 intermediary CA signed using RSA-MD5, and an end-entity certificate.
3084 To avoid chain validation errors due to the RSA-MD5 cert, you can
3085 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
3086 The signature on trusted certificates are not checked, so the chain
3087 has a chance to validate correctly. Reported by "Douglas E. Engert"
3088 <deengert@anl.gov> in
3089 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3091 ** libgnutls: Permit V1 Certificate Authorities properly.

3185 ** API and ABI modifications:
3186 No changes since last version.
3188 * Version 2.4.0 (released 2008-06-19)
3190 ** Major changes compared to the v2.2 branch:
3192 *** The OpenPGP sub-system has been improved and now supports subkeys.
3194 *** The PSK sub-system has been improved and now supports password
3195 *** derivation and PSK identity hints.
3196 The password derivation algorithms support is documented in
3197 draft-ietf-netconf-tls-02.txt.
3199 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
3200 This aligns terminology with OpenPGP, which doesn't use DER encoding.
3201 The old parameters will continue to work for some time.
3203 *** Certtool now confirm passwords and changes permissions of private key files.
3205 *** The default handshake size limit has been increased to 48kb.
3206 It appears as if some valid handshakes are large due to sending many
3207 CA certificates. (The earlier limit was 16kb.)
3209 *** LZO compression is now disabled by default.
3210 The main reason is that LZO compression in TLS is not standardized,
3211 but license compatiblity issues with minilzo triggered us to make this
3214 *** Improvements for cross-compilation to Windows and OpenWRT.
3216 *** The look of the GTK-DOC manual has been improved.
3217 Major developer visible changes compared to the v2.2 branch:
3219 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
3221 *** New APIs to access the raw X.509 Subject and Issuer DN's and
3222 *** elements from the certificate credentials structure.
3223 Thanks to Joe Orton.
3225 *** New APIs to improve working with username/passwords and PSK.
3227 *** Names of constants to affect certificate printing changed.
3228 The constants are used for OpenPGP too, which the names didn't
3229 reflect, so the following name change has been made:
3232 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
3233 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
3234 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
3236 The old names will be mapped to the new names for some time.
3238 *** The function gnutls_openpgp_privkey_get_id has been renamed to
3239 *** gnutls_openpgp_privkey_get_key_id.
3240 A compatibility mapping exists to avoid breaking API backwards
3243 *** Replaced all uses of alloca with malloc and free.
3245 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
3246 We have been unable to find a documented rationale for this practice.
3248 *** Of course, many smaller fixes have been made, see the ChangeLog file.
3250 *** API/ABI changes in GnuTLS 2.4
3251 All OpenPGP related functions have been moved from libgnutls-extra to
3252 libgnutls, and several new functions have been added (see below).
3253 Before making the release, we discussed whether moving functions from
3254 libgnutls-extra to libgnutls would require us to increment the ABI
3255 version, but the general opinion was that this would not be required.
3256 All older functions continue to work the same. We are open to the
3257 possibility that this decision will lead to problem on some platform,
3258 and if it turns out that the Right Thing should have been to increment
3259 the shared library version, we would need to release an update within
3260 the 2.4.x branch that increments the shared library version.
3262 This release adds the following functions:
3264 gnutls_psk_client_get_hint
3265 gnutls_psk_set_server_credentials_hint
3266 gnutls_psk_netconf_derive_key
3268 Used to get/set the PSK identity hint, and derive PSK keys from
3269 passwords a'la netconf.
3271 gnutls_x509_dn_deinit
3272 gnutls_x509_dn_export
3273 gnutls_x509_dn_import
3276 Used to handle X.509 Certificate DN's directly.
3280 Converts a data buffer to hex. Useful for handling PSK/SRP shared
3283 gnutls_certificate_get_x509_cas
3284 gnutls_certificate_get_x509_crls
3285 gnutls_certificate_get_openpgp_keyring
3287 Functions for direct access to credential elements.
3289 gnutls_openpgp_crt_get_auth_subkey
3290 gnutls_openpgp_crt_get_key_id
3291 gnutls_openpgp_crt_get_pk_dsa_raw
3292 gnutls_openpgp_crt_get_pk_rsa_raw

3310 gnutls_openpgp_privkey_export
3311 gnutls_openpgp_privkey_export_dsa_raw
3312 gnutls_openpgp_privkey_export_rsa_raw

3326 gnutls_openpgp_privkey_get_subkey_pk_algorithm
3327 gnutls_openpgp_privkey_get_subkey_revoked_status
3328 gnutls_openpgp_privkey_set_preferred_key_id
3330 New OpenPGP related functions.
3332 The function gnutls_openpgp_crt_get_key_id is the same as the old
3333 from gnutls_openpgp_crt_get_id, see above.
3335 The release also adds a new header file 'gnutls/crypto.h', however it
3336 is currently not used.
3338 ** libgnutls [OpenPGP]: New APIs to retrieve fingerprint from OpenPGP subkeys.
3339 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
3341 ** API and ABI modifications:
3342 gnutls_openpgp_crt_get_subkey_fingerprint: ADDED.
3343 gnutls_openpgp_privkey_get_subkey_fingerprint: ADDED.
3345 * Version 2.3.15 (released 2008-06-15)
3347 ** Disable the openpgp-certs self-tests.
3348 It results in failure under Wine and doesn't work on Debian buildds.

3351 No changes since last version.
3353 * Version 2.3.14 (released 2008-06-11)
3355 ** libgnutls [OpenPGP]: Changed OpenPGP verification behaviour.
3356 An OpenPGP certificate is now only considered verified if all the user
3359 ** Examples: Make C++ example compile.
3360 Earlier it may have failed with an unresolved reference to strlen.
3362 ** Documentation: Doc fix for gnutls_x509_crt_get_extension_oid.
3363 Reported by Sam Varshavchik <mrsam@courier-mta.com>.
3365 ** API and ABI modifications:
3366 No changes since last version.
3368 * Version 2.3.13 (released 2008-06-07)
3370 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
3372 ** doc/: Add psktool to info index. Some minor cleanups.
3374 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
3376 ** tests/: Added libgcrypt.supp which can be used with valgrind.
3377 The file suppresses the known libgcrypt memory leaks, so they aren't
3378 printed when you run valgrind on the gnutls self-tests. Use it as
3379 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add
3380 '--suppressions=/home/you/src/gnutls/tests/libgcrypt.supp' to your
3383 ** tests/: Reduce amount of debugging output by default.
3384 Use --verbose for each test to get the full output.
3386 ** tests/: Fix memory leaks in several self-tests.
3387 None of the self tests should be leaking memory when running valgrind
3388 or similar tools. (Known exceptions are dhepskself, pskself, and
3389 set_pkcs12_cred, which appear likely to be due to memory leaks in the
3392 ** API and ABI modifications:
3393 No changes since last version.
3395 * Version 2.3.12 (released 2008-06-04)
3397 ** Merge gnutls_with_netconf branch.
3399 *** libgnutls [PSK]: New API to retrieve PSK identity hint in client.
3400 The function is gnutls_psk_client_get_hint.
3402 *** libgnutls [PSK]: New API to set PSK identity hint in server.
3403 The function is gnutls_psk_set_server_credentials_hint.
3405 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
3406 In the client, the message is parsed and the application can use
3407 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
3408 message is sent if the application has specified a PSK identity hint
3409 using gnutls_psk_set_server_credentials_hint.
3411 *** libgnutls [PSK]: Support Netconf PSK key derivation.
3412 The function gnutls_psk_netconf_derive_key supports the PSK key
3413 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
3416 *** psktool: Support new --netconf-hint to generate PSK key from password.
3417 Uses the Netconf algorithm to derive PSK key from password.
3419 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
3421 *** gnutls-cli: Always support PSK modes, through a callback.
3422 The callback will derive a PSK key using Netconf algorithm. It will
3423 print the PSK identity hint to help the user.
3425 *** New PSK example client and server.
3426 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
3428 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.
3429 The code didn't work properly on platforms where 'char' is unsigned,
3430 when you set version 0. Reported by Laurence Withers
3431 <l@lwithers.me.uk> in
3432 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2825>.
3434 ** libgnutls-openssl: added RAND_pseudo_bytes API.
3435 Patch from Robert Millan <rmh@aybabtu.com>.
3437 ** API and ABI modifications:
3438 RAND_pseudo_bytes: ADDED to libgnutls-openssl.
3439 gnutls_psk_client_get_hint: ADDED.
3440 gnutls_psk_set_server_credentials_hint: ADDED.
3441 gnutls_psk_netconf_derive_key: ADDED
3443 * Version 2.3.11 (released 2008-05-20)
3445 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
3446 The flaw would result in incorrectly terminated sessions with the
3447 error "Decryption has failed" when the server sends a small packet
3448 (typically when the session is closed). Reported by Andreas Metzler
3449 <ametzler@downhill.at.eu.org> in

3452 ** Don't use gnulib headers when building C++ library.
3453 Fixes builds under Windows.
3455 ** Make umask a requirement.
3456 We don't know of any system that lacks it, even GNU CoreUtils use it
3459 ** Update gnulib files.
3460 Fixes a problem where it pulled in a replacement for memcmp under
3461 MinGW, which caused the C++ example to fail to build.
3463 ** API and ABI modifications:
3464 No changes since last version.
3466 * Version 2.3.10 (released 2008-05-19)
3468 ** Added wide wildcard hostname matching.
3469 Tiny patch by Jean-Philippe Garcia Ballester.
3471 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
3472 Thanks to CERT-FI for finding the bugs and providing detailed reports,
3473 which allowed the bugs to be reproduced and fixed easily. Patches
3474 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
3475 with more details about these vulnerabilities will be added to

3478 *** [GNUTLS-SA-2008-1-1]
3479 *** libgnutls: Fix crash when sending invalid server name.
3480 The crash can be triggered remotely before authentication, which can
3481 lead to a Daniel of Service attack to disable the server. The bug
3482 cause gnutls to store more session resumption data than what was
3483 allocated for, thus overwriting unallocated memory.
3485 *** [GNUTLS-SA-2008-1-2]
3486 *** libgnutls: Fix crash when sending repeated client hellos.
3487 The crash can be triggered remotely before authentication, which can
3488 lead to a Daniel of Service attack to disable the server. The bug
3489 triggers a null-pointer dereference.
3491 *** [GNUTLS-SA-2008-1-3]
3492 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3493 The crash can be triggered remotely before authentication, which can
3494 lead to a Daniel of Service attack to disable the server. The bug
3495 cause gnutls to read memory beyond the end of the received record.
3497 ** libgnutlsxx: Updated API according to patches from Eduardo
3498 Villanueva Che (discussion at
3499 <http://lists.gnu.org/archive/html/gnutls-devel/2007-02/msg00017.html>)
3501 ** Use umask to restrict permissions to owner before creating a file.
3503 ** API and ABI modifications:
3504 No changes since last version.
3506 * Version 2.3.9 (released 2008-05-16)
3508 ** libgnutls: Fix build failures if SRP/OpenPGP is disabled.
3509 Based on report and tiny patches from
3510 <jared.jennings.ctr@eglin.af.mil>, see
3511 <https://savannah.gnu.org/support/index.php?106342>.
3513 ** libgnutls: Translation fixes.
3515 ** gnutls-cli: Fix so that PSK authentication works.
3516 Also improve manual to give example for gnutls-cli PSK authentication.
3518 ** certtool: Encrypting a private key now require a confirmed password.
3519 Before './certtool -k -8' would merely ask for a password once.
3520 Reported by Daniel 'NebuchadnezzaR' Dehennin
3521 <nebuchadnezzar@asgardr.info> see
3522 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
3524 ** certtool: When writing private keys to files, change permissions of file.
3525 Now the file which the private key is saved to is chmod'ed 0600.
3526 Reported by martin f krafft <madduck@debian.org> see
3527 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
3529 ** guile: Fix -fgnu89-inline test.
3531 ** Removed --enable-profile-mode.
3532 The code linked gnutls with the libfc project (Function Check) which
3533 appears to have been stalled since around 2002.
3535 ** Clean up header file checks by ./configure.
3537 ** Update of gnulib files.
3539 ** API and ABI modifications:
3540 No changes since last version.
3542 * Version 2.3.8 (released 2008-04-29)
3544 ** libgnutls: Increase default handshake packet size limit to 48kb.
3545 The old limit was 16kb and some servers send huge list of trusted CAs,
3546 thus running into the limit. FYI, applications can further increase
3547 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3548 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3549 <marc@mclemente.net> for reporting and providing test servers.
3551 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
3552 Returned when the handshake data size is too large. Before
3553 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
3556 ** libgnutls: Hide definitions in crypto.h.
3557 We have decided that the APIs defined in crypto.h are not stable
3558 enough for v2.4, so don't use any of those functions.
3560 ** gnutls-cli: exit when hostname doesn't match certificate.
3561 Use --insecure to avoid hostname comparison.
3563 ** certtool: --inder and --outder replaced by --inraw and --outraw.
3564 The reason is to align terminology with OpenPGP, which doesn't use
3565 DER. The old parameters will continue to work for some time.
3567 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
3569 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
3571 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
3572 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
3573 vasprintf symbol from the libgcrypt library which caused problems.
3575 ** Update of gnulib files.
3577 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
3579 ** API and ABI modifications:
3580 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
3582 * Version 2.3.7 (released 2008-04-21)
3584 ** opencdk now properly sets the key usage bits into openpgp keys.
3586 ** gnutls-cli: Fix crash on TLS handshake failures.
3587 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
3588 This is similar to <http://bugs.debian.org/429183>.
3590 ** certtool: with --generate-request and newly generated keys, print the key.
3592 ** Build fixes for MinGW.
3593 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
3594 with -lws2_32 when needed. Use ASCII only isprint() when printing
3595 X.509 certificate information, to avoid non-ASCII but printable
3596 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for

3602 No changes since last version.
3604 * Version 2.3.6 (released 2008-04-17)
3606 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
3607 ** Improve documentation for gnutls_x509_crq_sign2.
3608 Based on report from "John Brooks" <aspecialj@gmail.com> in
3609 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
3611 ** tests/pathlen: run diff without parameters to improve portability.
3612 Based on HPUX build hints in
3613 <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>.
3615 ** Don't use %e specifier with strftime, it doesn't work under Windows.
3616 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3617 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3619 ** Remove all uses of gnutls_alloca/gnutls_afree.
3620 Use normal gnutls_malloc instead. One reason is increased portability
3621 to Windows, the other is that several of the uses may be unsafe
3622 because the size of data allocated could be large. Reported by
3623 Massimo Gaspari <massimo.gaspari@alice.it> in
3624 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3626 ** Build Guile code with -fgnu89-inline only when supported.
3627 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
3628 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
3630 ** Several GTK-DOC related fixes.
3632 ** Clean up OpenCDK related code.
3633 GnuTLS now requires its internal OpenCDK code rather than the external
3634 GPL library OpenCDK. Unfortunately, we don't have resources to
3635 maintain an external library (help welcome).
3637 ** API and ABI modifications:
3638 No changes since last version.
3640 * Version 2.3.5 (released 2008-04-14)
3642 ** Build fix for MinGW and --disable-shared.
3643 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3644 <http://permalink.gmane.org/gmane.network.gnutls.general/1145>.
3646 ** Document how to generate CRLs.
3647 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
3649 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3651 ** Several minor fixes in the OpenPGP interface.
3652 Thanks to Daniel Kahn Gillmor.
3654 ** Fix fopen file descriptor leak in PSK server code.
3655 Thanks to Laurence Withers <l@lwithers.me.uk>, see
3656 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
3658 ** Translations files not stored directly in git to avoid merge conflicts.
3660 ** New APIs to let applications replace the RNG used.
3661 Update all RNG callers in the code to use the new interface.
3663 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
3665 ** Update gnulib files.
3667 ** API and ABI modifications:
3668 gnutls_crypto_rnd_register: ADDED
3669 gnutls_rnd_level_t: ADDED
3670 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
3671 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
3672 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
3673 gnutls_crypto_rnd_st: ADDED
3674 GNUTLS_DIG_SHA224: ADDED
3675 GNUTLS_SIGN_RSA_SHA224: ADDED
3676 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
3678 * Version 2.3.4 (released 2008-03-19)
3680 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
3681 They weren't renamed in the public header file.
3683 ** Added functions to register a cipher/mac/digest. This allows to
3684 override the included ones.
3686 ** Fix a bunch of compiler warnings.
3688 ** API and ABI modifications:
3689 gnutls_crypto_cipher_st: ADDED
3690 gnutls_crypto_mac_st: ADDED
3691 gnutls_crypto_digest_st: ADDED
3692 gnutls_crypto_cipher_register: ADDED
3693 gnutls_crypto_mac_register: ADDED
3694 gnutls_crypto_digest_register: ADDED
3695 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
3697 * Version 2.3.3 (released 2008-03-10)
3699 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
3700 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
3702 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
3703 We could not find any modern justification for enabling these flags by
3704 default. If you know of some platform that needs one of the flags to
3705 work properly, please let us know. (Actually introduced in v2.3.0 but
3706 not documented until now.)
3708 ** Importing many CA certificates are now considerably faster.
3709 This affect gnutls_certificate_set_x509_trust_mem,
3710 gnutls_certificate_set_x509_trust, and
3711 gnutls_certificate_set_x509_trust_file. The complexity was reduced
3712 from O(2*n^2) to O(n). When adding 206 files containing 408
3713 certificates, using gnutls_certificate_set_x509_trust_file, the time
3714 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
3715 to trigger the problem. See also
3716 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
3718 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
3719 ** to be explicit that it takes zero terminated data.
3721 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.
3723 ** Documentation fixes for the GTK-DOC manual.
3725 ** Fix compilation error related to __FUNCTION__ on some systems.
3726 Reported by Tim Mooney, see
3727 <https://savannah.gnu.org/support/?106267>.
3729 ** Updated translations.
3731 ** Update gnulib files.
3733 ** API and ABI modifications:
3734 gnutls_hex2bin: MODIFIED, uses size_t instead of int for string length,
3735 and char* instead of void* for output buffer.
3737 * Version 2.3.2 (released 2008-02-26)
3739 ** Fix srcdir!=objdir failure in openpgpself test.
3741 ** Improved API documentation output from GTK-DOC.
3743 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
3745 ** Renamed gnutls_certificate_export_x509_cas and friends.
3746 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.
3748 ** Internal header files cleanup.
3750 ** API and ABI modifications:
3751 gnutls_certificate_export_x509_cas: RENAMED to gnutls_certificate_get_x509_cas
3752 gnutls_certificate_export_x509_crls: RENAMED to gnutls_certificate_get_x509_crls
3753 gnutls_certificate_export_openpgp_keyring: RENAMED to gnutls_certificate_get_openpgp_keyring
3754 gnutls_x509_dn_export: ADDED
3756 * Version 2.3.1 (released 2008-02-21)
3758 ** OpenPGP support merged into libgnutls and is now licensed under LGPL.
3759 The included copy of OpenCDK has been stripped down and re-licensed
3762 ** Cipher priority string handling now handle strings that starts with NULL.
3763 Thanks to Laurence Withers <l@lwithers.me.uk>.
3765 ** gnutls-cli: When -d is used, also prints RNG information from libgcrypt.
3767 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
3770 ** Increased the default certificate verification chain limits and allowed
3771 for checks without limitation.
3773 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
3774 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
3775 strings and return the proper size.
3777 ** Add section 'On Record Padding' to the manual.
3778 This collects all problems related to record padding with
3779 Nokia/Sony-Ericsson phones that we know about.
3781 ** Several improvements in the OpenPGP authentication.
3782 Now subkeys can be used for authentication, according to
3783 draft-mavrogiannopoulos-rfc5081bis-00.txt.
3785 ** certtool can print information on OpenPGP certificates and keys.
3787 ** Added gnutls_x509_dn_import/init/deinit() to access raw DER DN.
3790 ** Added gnutls_certificate_export_x509_cas and other functions to
3791 export elements from the certificate credentials structure. Based on
3792 suggestion from Joe Orton.
3795 Clarify that srp_base64 is not the same as normal base64.
3797 ** Fix non-portable use of brace expansion in makefiles.
3799 ** API and ABI modifications:
3800 gnutls_certificate_export_x509_cas: ADDED
3801 gnutls_certificate_export_x509_crls: ADDED
3802 gnutls_certificate_export_openpgp_keyring: ADDED
3803 gnutls_openpgp_keyid_t: ADDED, instead of hard-coded 'unsigned char[8]'.
3804 gnutls_openpgp_crt_get_key_id: ADDED, obsoletes gnutls_openpgp_crt_get_id.
3805 gnutls_openpgp_crt_get_revoked_status: ADDED
3806 gnutls_openpgp_crt_get_subkey_count: ADDED
3807 gnutls_openpgp_crt_get_subkey_idx: ADDED
3808 gnutls_openpgp_crt_get_subkey_revoked_status: ADDED
3809 gnutls_openpgp_crt_get_subkey_pk_algorithm: ADDED
3810 gnutls_openpgp_crt_get_subkey_creation_time: ADDED
3811 gnutls_openpgp_crt_get_subkey_expiration_time: ADDED
3812 gnutls_openpgp_crt_get_subkey_id: ADDED
3813 gnutls_openpgp_crt_get_subkey_usage: ADDED
3814 gnutls_openpgp_privkey_get_fingerprint: ADDED
3815 gnutls_openpgp_privkey_get_key_id: ADDED
3816 gnutls_openpgp_privkey_get_subkey_count: ADDED

3818 gnutls_openpgp_privkey_get_subkey_revoked_status: ADDED
3819 gnutls_openpgp_privkey_get_revoked_status: ADDED
3820 gnutls_openpgp_privkey_get_subkey_pk_algorithm: ADDED
3821 gnutls_openpgp_privkey_get_subkey_expiration_time: ADDED
3822 gnutls_openpgp_privkey_get_subkey_id: ADDED

3824 gnutls_openpgp_crt_get_subkey_pk_dsa_raw: ADDED
3825 gnutls_openpgp_crt_get_subkey_pk_rsa_raw: ADDED
3826 gnutls_openpgp_crt_get_pk_dsa_raw: ADDED

3828 gnutls_openpgp_privkey_export_subkey_dsa_raw: ADDED
3829 gnutls_openpgp_privkey_export_subkey_rsa_raw: ADDED
3830 gnutls_openpgp_privkey_export_dsa_raw: ADDED

3839 gnutls_hex2bin: ADDED
3840 GNUTLS_CRT_PRINT_FULL: ADDED, same as old GNUTLS_X509_CRT_FULL.
3841 GNUTLS_CRT_PRINT_ONELINE: ADDED, same as old GNUTLS_X509_CRT_ONELINE.
3842 GNUTLS_CRT_PRINT_UNSIGNED_FULL: ADDED, same as
3843 old GNUTLS_X509_CRT_UNSIGNED_FULL.
3845 * Version 2.3.0 (released 2008-01-08)
3847 ** LZO compression is now disabled by default.
3848 The reason is that LZO compression is not standardized in TLS. If you
3849 wish to experiment with it, you will have to supply --with-lzo when
3850 invoking ./configure. The internal copy of minilzo is no longer
3851 included with GnuTLS, so you will need to install liblzo or liblzo2 on
3852 your system to have --with-lzo to be effective.
3854 ** More than one server name field is now sent to the server properly.
3855 Thanks to mark.phillips@virgin.net.
3857 ** Fixes the post_client_hello_function(). The extensions are now parsed
3858 in a callback friendly way.
3860 ** Fix for certificate selection in servers with certificate callbacks.
3862 ** Updated translations.
3864 ** Update gnulib files.
3866 ** API and ABI modifications:
3867 No changes since last version.
3869 * Version 2.2.5 (released 2008-05-19)
3871 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
3872 The flaw would result in incorrectly terminated sessions with the
3873 error "Decryption has failed" when the server sends a small packet
3874 (typically when the session is closed). Reported by Andreas Metzler
3875 <ametzler@downhill.at.eu.org> in
3876 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
3878 ** API and ABI modifications:
3879 No changes since last version.
3881 * Version 2.2.4 (released 2008-05-19)
3883 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
3884 Thanks to CERT-FI for finding the bugs and providing detailed reports,
3885 which allowed the bugs to be reproduced and fixed easily. Patches
3886 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
3887 with more details about these vulnerabilities will be added to
3888 <http://www.gnu.org/software/gnutls/security.html>
3890 *** [GNUTLS-SA-2008-1-1]
3891 *** libgnutls: Fix crash when sending invalid server name.
3892 The crash can be triggered remotely before authentication, which can
3893 lead to a Daniel of Service attack to disable the server. The bug
3894 cause gnutls to store more session resumption data than what was
3895 allocated for, thus overwriting unallocated memory.
3897 *** [GNUTLS-SA-2008-1-2]
3898 *** libgnutls: Fix crash when sending repeated client hellos.
3899 The crash can be triggered remotely before authentication, which can
3900 lead to a Daniel of Service attack to disable the server. The bug
3901 triggers a null-pointer dereference.
3903 *** [GNUTLS-SA-2008-1-3]
3904 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3905 The crash can be triggered remotely before authentication, which can
3906 lead to a Daniel of Service attack to disable the server. The bug
3907 cause gnutls to read memory beyond the end of the received record.
3909 ** API and ABI modifications:
3910 No changes since last version.
3912 * Version 2.2.3 (released 2008-05-06)
3914 ** Increase default handshake packet size limit to 48kb.
3915 The old limit was 16kb and some servers send huge list of trusted CAs,
3916 thus running into the limit. FYI, applications can further increase
3917 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3918 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3919 <marc@mclemente.net> for reporting and providing test servers.
3921 ** Fix compilation error related to __FUNCTION__ on some systems.
3922 Reported by Tim Mooney, see
3923 <https://savannah.gnu.org/support/?106267>.
3925 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3927 ** Fix fopen file descriptor leak in PSK server code.
3928 Thanks to Laurence Withers <l@lwithers.me.uk>, see
3929 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
3931 ** Build Guile code with -fgnu89-inline only when supported.
3932 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
3933 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
3935 ** Make Camellia encryption work.
3936 Reported by Yoshisato YANAGISAWA <yanagisawa@csg.is.titech.ac.jp> in
3937 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2746>.
3939 ** API and ABI modifications:
3940 No changes since last version.
3942 * Version 2.2.2 (released 2008-02-21)
3944 ** Cipher priority string handling now handle strings that starts with NULL.
3945 Thanks to Laurence Withers <l@lwithers.me.uk>.
3947 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
3950 ** Increased the default certificate verification chain limits and allowed
3951 for checks without limitation.
3953 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
3954 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
3955 strings and return the proper size.
3957 ** API and ABI modifications:
3958 No changes since last version.
3960 * Version 2.2.1 (released 2008-01-17)
3962 ** Prevent linking libextra against previously installed libgnutls.
3963 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
3964 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
3966 ** Fixes the post_client_hello_function(). The extensions are now parsed
3967 in a callback friendly way.
3969 ** Fix for certificate selection in servers with certificate callbacks.
3971 ** API and ABI modifications:
3972 No changes since last version.
3974 * Version 2.2.0 (released 2007-12-14)
3976 ** Update internal copy of libtasn1 to version 1.2.
3978 ** Certtool --verify-chain now handle inputs larger than 64kb.
3979 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
3980 recent versions of libgcrypt. The problem was that Wine with the
3981 libgcrypt RNG generates huge amounts of debugging output.
3983 ** Translation updates.
3984 Added Dutch translation. Updated Polish and Swedish translation.
3986 ** Major changes compared to the v2.0 branch:
3988 *** SRP support aligned with newly published RFC 5054.
3990 *** OpenPGP support aligned with newly published RFC 5081.
3992 *** Support for DSA2 keys.
3994 *** Support for Camellia cipher.
3996 *** Support for Opaque PRF Input extension.
3998 *** PKCS#8 parser now handle DSA keys.
4000 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
4001 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
4002 versions, such as 2.01 which is included with GnuTLS, is available
4003 under GPLv2 or later. If this incompatibility causes problems, we
4004 recommend you to disable LZO using --without-lzo. LZO compression is
4005 not a standard TLS compression algorithm, so the impact should be
4008 *** Functions for disabling record protocol padding.
4009 Works around bugs on Nokia/Ericsson phones.
4011 *** New functions gnutls_priority_set() for setting cipher priorities easily.
4012 Priorities like "COMPAT" also enables other work arounds, such as
4015 *** Other minor improvements and bug fixes.
4017 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
4018 To adapt to changes in the TLS extension specifications for OpenPGP
4019 and SRP, the GnuTLS API had to be modified. This means breaking the
4020 API and ABI backwards compatibility. That is something we try to
4021 avoid unless it is necessary. We decided to also remove the already
4022 deprecated stub functions for X.509 to XML conversion and TLS
4023 authorization (see below) when we had the opportunity.
4025 Generally, most applications does not need to be modified. Just
4026 re-compile them against the latest GnuTLS release, and it should work
4029 Applications that use the OpenPGP or SRP features needs to be
4030 modified. Below is a list of the modified APIs and discussion of what
4031 the minimal things you need to modify in your application to make it
4032 work with GnuTLS 2.2.
4034 Note that GnuTLS 2.2 also introduces new APIs -- such as
4035 gnutls_set_priority() that is superior to
4036 gnutls_set_default_priority() -- that you may want to start using.
4037 However, using those new APIs is not required to use GnuTLS 2.2 since
4038 the old functions continue are still supported. This text only
4039 discuss what you minimally have to modify.
4041 *** XML related changes
4042 The function `gnutls_x509_crt_to_xml' has been removed. It has been
4043 deprecated and only returned an error code since GnuTLS version
4044 1.2.11. Nobody has complained, so users doesn't seem to miss the
4045 functionality. We don't know of any other library to convert X.509
4046 certificates into XML format, but we decided (long ago) that GnuTLS
4047 isn't the right place for this kind of functionality. If you want
4048 help to find some other library to use here, please explain and
4049 discuss your use case on help-gnutls@gnu.org.
4051 *** TLS Authorization related changes
4052 Everything related to TLS authorizations have been removed, they were
4053 only stub functions that returned an error code:
4055 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
4056 gnutls_authz_data_format_type_t
4057 gnutls_authz_recv_callback_func
4058 gnutls_authz_send_callback_func
4060 gnutls_authz_send_x509_attr_cert
4061 gnutls_authz_send_saml_assertion
4062 gnutls_authz_send_x509_attr_cert_url
4063 gnutls_authz_send_saml_assertion_url
4065 *** SRP related changes
4066 The callback gnutls_srp_client_credentials_function has a new
4067 prototype, and its semantic has changed. You need to rewrite the
4068 callback, see the updated function documentation and SRP example code
4069 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
4072 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
4073 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
4074 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
4075 used. There are #define's to map the old names to the new. You may
4076 run into problems if you have a switch-case with cases for both SRP
4077 alerts, since they are now mapped to the same value. The solution is
4078 to drop the SRP alerts from such switch cases, as they are now
4079 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
4081 *** OpenPGP related changes
4082 The function `gnutls_certificate_set_openpgp_keyserver' have been
4083 removed. There is no replacement functionality inside GnuTLS. If you
4084 need keyserver functionality, consider using the GnuPG tools.
4086 All functions, types, and error codes related to OpenPGP trustdb
4087 format have been removed. The trustdb format is a non-standard
4088 GnuPG-specific format, and we recommend you to use key rings instead.
4089 The following have been removed:
4091 gnutls_certificate_set_openpgp_trustdb
4092 gnutls_openpgp_trustdb_init
4093 gnutls_openpgp_trustdb_deinit
4094 gnutls_openpgp_trustdb_import

4099 The following functions has an added parameter of the (new) type
4100 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
4101 (binary or base64). The functions are:
4102 gnutls_certificate_set_openpgp_key_file
4103 gnutls_certificate_set_openpgp_key_mem
4104 gnutls_certificate_set_openpgp_keyring_mem
4105 gnutls_certificate_set_openpgp_keyring_file
4107 To improve terminology and align with the X.509 interface, some
4108 functions have been renamed. Compatibility mappings exists. The old
4109 and new names of the affected functions and types are:
4112 gnutls_openpgp_key_t gnutls_openpgp_crt_t
4113 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t

4132 ** API and ABI modifications:
4133 No changes since last version.
4135 * Version 2.1.8 (released 2007-12-10)
4137 ** The GPL version has been changed from version 2 to version 3.
4138 This affects the self-tests, command-line tools, the libgnutls-extra
4139 library, the relevant guile parts, and the build environment.
4141 ** Added gnutls_x509_crt_get_subject_alt_name2().
4143 ** Corrected a segfault when setting an empty gnutls_priority_t
4144 at gnutls_priority_set().
4146 ** Use gettext 0.17 which updates m4/lib-*.m4 macros.
4147 Fixes a problem with spurious -L/usr/lib additions.
4149 ** API and ABI modifications:
4150 gnutls_x509_crt_get_subject_alt_name2: ADD.
4152 * Version 2.1.7 (released 2007-11-29)
4154 ** PKCS #8 parser can now encode/decode DSA keys.
4156 ** Updated gnutls_set_default_priority2() now renamed to
4157 gnutls_priority_set() and gnutls_priority_set_direct() which
4158 accept a string to indicate preferences of ciphersuite parameters.
4160 ** gnutls-cli and gnutls-serv now have a --priority option to set
4161 the priority string.
4163 ** The gnutls_*_convert_priority() functions were deprecated by
4164 the gnutls_priority_set() and gnutls_priority_set_direct().
4166 ** Internal copy of OpenCDK upgraded to version 0.6.6.
4168 ** API and ABI modifications:
4169 gnutls_priority_init: ADD.
4170 gnutls_priority_deinit: ADD.
4171 gnutls_priority_set: ADD.
4172 gnutls_priority_set_direct: ADD.

4180 gnutls_set_default_priority: UNDEPRECATED
4181 gnutls_set_default_priority_export: UNDEPRECATED
4183 ** Undocumented API and ABI modifications earlier in the 2.1.x series:
4184 GNUTLS_CIPHER_UNKNOWN: ADD.
4185 GNUTLS_CIPHER_CAMELLIA_128_CBC: ADD.
4186 GNUTLS_CIPHER_CAMELLIA_256_CBC: ADD.

4197 gnutls_certificate_send_x509_rdn_sequence: ADD prototype to gnutls.h.in.
4199 * Version 2.1.6 (released 2007-11-15)
4201 ** Corrected bug in decompression of expanded compression data.
4203 ** Added the --to-p8 option to certtool to convert private keys
4206 ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code.
4208 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
4211 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
4212 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
4213 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
4214 documented. This caused some problems (e.g., debian #450854). To
4215 avoid backwards compatibility problems, this release revert this
4216 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
4217 done in GnuTLS 2.0.x and earlier, and add a new error code
4218 GNUTLS_E_UNKNOWN_ALGORITHM.
4220 ** Fixes several gtk-doc warnings.
4222 ** API and ABI modifications:
4223 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
4224 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
4225 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
4227 * Version 2.1.5 (released 2007-11-01)
4229 ** Fix PKCS#3 parameter export problem.
4231 ** Improve certtool queries, they now print the default value.
4235 ** Update gnulib files.
4237 ** API and ABI modifications:
4238 No changes since last version.
4240 * Version 2.1.4 (released 2007-10-27)
4242 ** Added the --v1 option to certtool, to allow generating X.509
4243 version 1 certificates.
4245 ** certtool: Add option --disable-quick-random to enable the old behaviour
4246 of using /dev/random to generate keys.
4248 ** Added priority functions that accept strings.
4250 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
4251 priorities preferences.
4253 ** Added gnutls_record_disable_padding() to allow servers talking to
4254 buggy clients that complain if the TLS 1.0 record protocol padding is
4257 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
4258 all supported compatibility options (like disabling padding).
4260 ** The gnutls_certificate_set_openpgp_* functions were modified to include
4261 the format. This makes the interface consistent with the x509 functions.
4263 ** Internal copy of OpenCDK upgraded to version 0.6.5.
4265 ** Update gnulib files.

4302 * Version 2.1.3 (released 2007-10-17)
4304 ** TLS authorization support removed.
4305 This technique may be patented in the future, and it is not of crucial
4306 importance for the Internet community. After deliberation we have
4307 concluded that the best thing we can do in this situation is to
4308 encourage society not to adopt this technique. We have decided to
4309 lead the way with our own actions.
4311 ** Re-enabled the 256 bit ciphers in the default priorities.
4313 ** Corrected bugs in openpgp key verification using a keyring (both in

4326 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
4327 gnutls_supplemental_data_format_type_t enum type becomes empty.
4329 * Version 2.1.2 (released 2007-10-14)
4331 ** Removed all the trustdb code from openpgp authentication.
4332 We now use only the well-specified keyrings.
4334 ** The 256 bit ciphers are not enabled in the default priorities.
4336 ** Added support for DSA2 using libgcrypt 1.3.0.
4338 ** certtool: Fixed data corruption when using --outder.
4340 ** Removed all the xml related stubs and functions.
4342 ** Added capability to set a callback after the client hello is received
4343 by the server in order to adjust parameters before the handshake.
4345 ** SRP was corrected to adhere to the latest draft (published soon as RFC)
4347 ** Corrected bug which did not allow a server to run without supporting
4350 ** Updated the DN parser which now prints wrongly decoded values as hex
4353 ** certtool: Add option --quick-random.

4369 GNUTLS_A_UNKNOWN_SRP_USERNAME: DEPRECATED
4371 * Version 2.1.1 (released 2007-09-24)
4373 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
4374 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
4375 compiled with Camellia support. See the libgcrypt documentation on
4376 how to enable it. Unconditionally disable it using the configure
4377 option --disable-camellia. Fixes #1.
4379 ** Properly document in the NEWS file the API change in the last release.
4381 ** API and ABI modifications:
4382 No changes since last version.
4384 * Version 2.1.0 (released 2007-09-20)
4386 ** Support for draft-rescorla-tls-opaque-prf-input-00.txt.
4387 The support is disabled by default. Since no value has been allocated
4388 by the IANA for this extension yet, you will need to provide one
4389 yourself by invoking './configure --enable-opaque-prf-input=42'.
4392 ** Example code: Fix compilation flaw under MinGW.
4394 ** API and ABI modifications:
4395 gnutls_oprfi_callback_func: ADD, new typedef function prototype.
4396 gnutls_oprfi_enable_client: ADD, new function.

4428 ** TLS authorization support removed.
4429 This technique may be patented in the future, and it is not of crucial
4430 importance for the Internet community. After deliberation we have
4431 concluded that the best thing we can do in this situation is to
4432 encourage society not to adopt this technique. We have decided to
4433 lead the way with our own actions.
4435 ** certtool: Fixed data corruption when using --outder.
4437 ** Fix configure-time Guile detection.
4439 ** API and ABI modifications:
4440 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
4441 gnutls_supplemental_data_format_type_t enum type becomes empty.
4443 * Version 2.0.1 (released 2007-09-20)
4445 ** New directory doc/credentials/ with test credentials.
4446 This collects the test credentials from the web page and from src/.
4447 The script gnutls-http-serv has also been moved to that directory.
4449 ** Update SRP extension type and cipher suite with official IANA values.
4450 This breaks backwards compatibility with SRP in older versions of
4451 GnuTLS, but this is intentional to speed up the adoption of the
4452 official values. The old values we used were incorrect.
4454 ** Guile: Fix `x509-certificate-dn-oid'
4456 ** API and ABI modifications:
4457 No changes since last version.
4459 * Version 2.0.0 (released 2007-09-04)
4461 ** Included copy of Libtasn1 upgraded to version 1.1.
4463 ** Disable building of some examples if anonymous ciphers are disabled.
4465 ** Don't build examples for disabled features.
4467 ** API and ABI modifications:
4468 No changes since last version.
4470 * Version 1.7.19 (released 2007-08-27)
4472 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
4473 This solves connection problems in mutt, see
4474 <http://bugs.debian.org/439640>.
4476 ** Update gnulib files.
4477 In particular, the getpass module -- with its dependencies on getline,
4478 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
4479 library) directory to the gl/ directory (only used by the command line
4480 tools). The reason is that getpass is now only used by the
4481 command-line tools, and reducing the number of gnulib modules linked
4482 to the core library helps portability and reduces size.
4486 ** Disable building of PGP examples if PGP is disabled.
4488 ** Included copy of OpenCDK upgraded to version 0.6.4.
4490 ** API and ABI modifications:
4491 No changes since last version.
4493 * Version 1.7.18 (released 2007-08-16)
4495 ** Install images for the info manual.
4496 This has a side effect of renaming the images. See
4497 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
4498 discussions on the approach chosen.
4500 ** Fix pointer mix to variables of different size.
4501 Patch extracted from
4502 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
4504 ** Fix warnings during build.
4505 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
4507 ** API and ABI modifications:
4508 No changes since last version.
4510 * Version 1.7.17 (released 2007-08-15)
4512 ** New functions to perform external signing.
4513 Set the signing callback function (of the gnutls_sign_func prototype)
4514 using the gnutls_sign_callback_set function. In the callback, you may
4515 find the new functions gnutls_x509_privkey_sign_hash and
4516 gnutls_openpgp_privkey_sign_hash useful. A new function
4517 gnutls_sign_callback_get is also added, to retrieve the function
4518 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
4519 comments and testing.
4521 ** New self test of client and server authenticated X.509 TLS sessions.
4522 See tests/x509self.c and tests/x509signself.c. The latter also tests
4523 the new external signing callback interface.
4525 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
4526 These two actually describe the outer limits of a range of error codes
4527 reserved to the application. All of the errors are treated as fatal
4528 by the library (it has to since it doesn't know the semantics of the
4529 error codes). This can be useful in callbacks, to signal some
4530 application-specific error condition, which will usually eventually
4531 cause some gnutls API to return the same error code as the callback,
4532 which then can be inspected by the application. Note that error codes
4535 ** gnutls_set_default_priority now disable TLS 1.2 by default.
4536 The RFC is not released yet, and we're approaching a major release so
4537 let's not enable it just yet.
4539 ** Fix namespace so that gnutls_*_t is used consistently.
4540 Before, many places in the GnuTLS code used the old deprecated type
4541 names without the '_t' suffix.
4543 ** Build fixes for Guile code.
4544 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
4546 ** More documentation fixes.
4547 In particular, the section headings were modified for casing. By
4548 Ludovic Courtes <ludovic.courtes@laas.fr>.
4550 ** Updated Polish and Swedish translations.
4551 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
4552 <po@danielnylander.se>.
4554 ** API and ABI modifications:
4555 gnutls_sign_func: ADD, new type for sign callback.
4556 gnutls_sign_callback_set: ADD, new function to set sign callback.
4557 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
4558 gnutls_x509_privkey_sign_hash,
4559 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
4560 GNUTLS_E_APPLICATION_ERROR_MIN,
4561 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
4563 * Version 1.7.16 (released 2007-08-07)
4565 ** Fix sanity checks and return values in certificate selection.
4566 In some cases, GnuTLS omitted to report suitable error codes when no
4567 suitable certificate was found.
4569 ** Fix gnutls-cli starttls EOF on Mac OS X.
4570 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
4572 ** Documentation fixes.
4573 In particular, the section headings were modified for casing. By
4574 Ludovic Courtes <ludovic.courtes@laas.fr>.
4576 ** Update gnulib files.
4578 ** API and ABI modifications:
4579 No changes since last version.
4581 * Version 1.7.15 (released 2007-07-02)
4583 ** Fix self-tests key-id under mingw32.
4585 ** Test that the Guile header files are recent enough to work.
4586 Before we just tested that the command line tool 'guile' was recent
4587 enough, which may not be sufficient if you still have an old
4588 libguile.h header installed.
4590 ** Guile bindings are now installed under $prefix by default.
4591 Use --without-guile-site-dir to install it under $pkgdatadir/site/
4592 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
4593 Use --with-guile-site-dir=/your/own/path to specify the path manually.
4594 The default, --with-guile-site-dir, will install the Guile bindings
4595 under $datadir/guile/site. There is a new section 'Guile
4596 Preparations' in the manual that discuss these issues.
4598 ** Fix run-time library path ordering in linking the Guile bindings.
4600 ** Improved manual on downloading, installing, getting help, bug reports etc.

4682 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
4684 ** API and ABI modifications:
4685 No changes since last version.
4687 * Version 1.7.10 (released 2007-05-25)
4689 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
4690 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
4692 ** Update of gnulib files.
4694 ** GnuTLS is now developed in GIT instead of CVS.
4695 See <http://repo.or.cz/w/gnutls.git> for a public repository.
4697 ** API and ABI modifications:
4698 gnutls_x509_crt_get_raw_issuer_dn: ADD.
4699 gnutls_x509_crt_get_raw_dn: ADD.
4701 * Version 1.7.9 (released 2007-05-12)
4703 ** X.509 certificates are preferred over OpenPGP keys.
4704 This is a change in the semantics of gnutls_set_default_priority.
4706 ** The included copy of OpenCDK has been updated to 0.6.1.
4707 There has been some API changes in OpenCDK, and the GnuTLS layer have
4708 been modified as well. Note that while there are API/ABI incompatible
4709 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
4710 its API/ABI have not changed. From this version on, GnuTLS requires
4711 OpenCDK 0.6.0 or later.
4713 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
4715 ** Change certtool's default serial number from 0 to a time-based value.
4717 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
4718 Before, we remove the parameters field, which resulted in a slightly
4719 different DER encoding which in turn caused signature verification
4720 failures of GnuTLS-generated RSA certificates in some other
4721 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
4722 you read, this may or may not be correct, but our new behaviour appear
4723 to be consistent with other widely used implementations.
4725 ** Fix mem leaks in gnutls_x509_crt_print.
4727 ** API and ABI modifications:
4728 No changes since last version.
4730 * Version 1.7.8 (released 2007-04-16)
4732 ** Added examples for the authorization extension.
4733 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
4735 ** The examples only use gnutls_set_default_priority().
4736 The exception is when DH_ANON is needed.
4738 ** Improve gnutls_set_default_priority() priorities.
4739 The new approach is for it to try and negotiate all secure and
4740 standard mechanisms available. Currently, DH_ANON ciphersuites and
4741 LZO compressions are not enabled by default, because they are,
4742 respectively, insecure and non-standardized. Note that TLS 1.2 will
4743 not be enabled by default in non-experimental release until it has
4744 been approved by the IETF.
4746 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
4747 This means that to get DH_ANON and LZO compression, you'll need to
4748 specify that manually using '--kx anon' or '--comp lzo'.
4750 ** Minor fixes to the human display format of X.509 certificates.
4752 ** New APIs to extract Distinguished Name's from X.509 certificates.
4753 Based on patch from Howard Chu <hyc@symas.com>.
4755 ** Improved library searching for opencdk.
4756 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
4757 The deprecated opencdk.m4 is no longer used.
4759 ** New APIs to list supported algorithms in the library.
4760 The APIs are gnutls_cipher_list, gnutls_mac_list,
4761 gnutls_compression_list, gnutls_protocol_list,
4762 gnutls_certificate_type_list, gnutls_kx_list, and
4763 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
4765 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
4767 ** New configure option --disable-tls-authorization to disable tls-authz.
4769 ** Fix prototype for `gnutls_psk_set_client_credentials'.
4770 The last parameter was renamed from 'flags' to 'format' and the type
4771 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
4772 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
4775 ** Fix allocation in gnutls_certificate_set_openpgp_key.
4776 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
4778 ** API and ABI modifications:
4779 gnutls_x509_dn_t: ADD.
4780 gnutls_x509_ava_st: ADD.
4781 gnutls_x509_crt_get_subject,
4782 gnutls_x509_crt_get_issuer: ADD.
4783 gnutls_x509_dn_get_rdn_ava: ADD.
4784 gnutls_cipher_list: ADD.
4785 gnutls_mac_list: ADD.
4786 gnutls_compression_list: ADD.
4787 gnutls_protocol_list: ADD.
4788 gnutls_certificate_type_list: ADD.
4789 gnutls_kx_list: ADD.
4790 gnutls_cipher_suite_info: ADD.
4792 * Version 1.7.7 (released 2007-02-22)
4794 ** Support for supplemental handshake messages and authorization data.
4795 Supplemental data is described in RFC 4680 and the authorization
4796 extensions in draft-housley-tls-authz-extns-07.
4798 ** Support for authorization data in gnutls-cli and gnutls-serv.
4799 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
4801 ** Fix for gnutls_x509_crt_check_hostname.
4802 Before it would have reported that the certificate matched a hostname
4803 when it did not have any dNSName or any CN field. Report and tiny
4804 patch from "Richard W.M. Jones" <rjones@redhat.com>.
4806 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
4807 Tests regressions of the bug, and several other features.
4809 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
4810 Before there were no support for iPAddress SAN's during comparison.
4812 ** New API to print information about CRL's.
4813 The function is gnutls_x509_crl_print.
4815 ** New API to extract signature value from CRL's.
4816 The function is gnutls_x509_crl_get_signature.
4818 ** Support for directoryName Subject Alternative Name's.
4819 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
4820 string in the provided buffer.
4822 ** Internal improvements to certtool.
4823 It uses gnutls_x509_crl_print to print CRL information. It uses some
4824 more gnulib modules to simplify error handling.
4826 ** API and ABI modifications:
4827 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
4828 gnutls_supplemental_data_format_type_t: ADD.
4829 gnutls_authz_data_format_type_t: ADD.
4830 gnutls_supplemental_get_name: ADD.
4831 gnutls_authz_recv_callback_func,
4832 gnutls_authz_send_callback_func: ADD, callback prototypes.
4833 gnutls_authz_enable: ADD.
4834 gnutls_authz_send_x509_attr_cert,
4835 gnutls_authz_send_saml_assertion,
4836 gnutls_authz_send_x509_attr_cert_url,
4837 gnutls_authz_send_saml_assertion_url: ADD.
4838 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
4839 gnutls_x509_crl_print: ADD.
4840 gnutls_x509_crl_get_signature: ADD.
4842 * Version 1.7.6 (released 2007-02-12)
4844 ** Support for 'otherName' Subject Alternative Names.
4845 The existing API gnutls_x509_crt_get_subject_alt_name may now return
4846 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
4847 To find out the otherName OID (necessary for proper parsing of the
4848 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
4849 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
4850 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
4851 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
4853 ** Certtool can print otherName SAN values for certificates.
4854 For known otherName OIDs (currently only id-on-xmppAddr as defined by
4855 RFC 3920), it will also print the name.
4857 ** Fix TLS 1.2 RSA signing in servers.
4858 Before it used the old-style MD5+SHA1 signature, but the TLS
4859 signatures should be normal PKCS#1 signatures. FYI, we use and
4860 require that DigestInfo parameters are present and NULL for TLS 1.2.
4862 ** Add APIs to access X.509 extensions sequentially.
4863 The existing APIs gnutls_x509_crt_get_extension_oid() and
4864 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
4865 inspect the extensions in the order defined by the certificate.
4867 ** Add API to extract signature value from X.509 certificates.
4868 The function is gnutls_x509_crt_get_signature.
4870 ** Fix crash when generating proxy certificates in batch mode.
4871 If you don't specify a proxy policy in batch mode, it will use
4874 ** Add API to print information about X.509 certificates.
4875 The function is gnutls_x509_crt_print.
4877 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
4878 One consequence of this is that the output syntax has changed
4879 slightly. Some more fields are printed.
4883 ** API and ABI modifications:
4884 gnutls_x509_crt_print: ADD
4885 gnutls_certificate_print_formats_t: ADD, new enum.
4886 gnutls_x509_crt_get_signature: ADD.
4887 gnutls_x509_crt_get_extension_data: ADD.
4888 gnutls_x509_crt_get_extension_info: ADD.
4889 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
4890 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
4891 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
4893 * Version 1.7.5 (released 2007-02-06)
4895 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
4898 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
4900 ** Fix --list output for gnutls-cli and gnutls-serv.
4901 Mention TLS1.2, SHA512 etc.
4903 ** Manual contains new section on setting up a test HTTP server.
4904 A server set up following those descriptions are available online via
4905 <http://www.gnutls.org/server.html>.
4907 ** Update of gnulib files.
4909 ** API and ABI modifications:
4910 No changes since last version.
4912 * Version 1.7.4 (released 2007-02-05)
4914 ** Support for RSA signing using SHA-256/384/512.
4915 A new self test "sha2" tries to build a long X.509 certificate chain
4916 testing all new hashes.
4918 ** The gnutls-serv tool now use static DH parameters if none are supplied.
4920 ** Discuss proxy certificates in the manual.
4922 ** Improve bibliographical citations in the manual.
4924 ** Update of gnulib files.
4926 ** Fix certtool template handling of pathLenConstraints.
4927 It now defaults to -1 instead of 0, which causes the field to be
4928 missing unless the template specify it.
4930 ** API and ABI modifications:
4933 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
4936 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
4937 GNUTLS_SIGN_RSA_SHA256,
4938 GNUTLS_SIGN_RSA_SHA384,
4939 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
4941 * Version 1.7.3 (released 2007-02-01)
4943 ** New option to certtool: --generate-proxy.
4944 This will generate a Proxy Certificate from an end entity certificate.
4945 Proxy Certificates are documented in RFC 3820. You will need to
4946 specify the proxy certificate's private key with --load-privkey, the
4947 user certificate with --load-certificate and the private key used to
4948 sign the new proxy certificate with --load-ca-privkey. Certtool will
4949 query for proxy path length and the policy language OID. Currently
4950 only OIDs that have an empty policy are supported (which includes the
4951 two OIDs defined by RFC 3820).
4953 ** Certtool --certificate-info now prints information for Proxy Certificates.
4954 Before the proxy extension was just printed as DER encoded data.
4956 ** New APIs to set proxy subject names and get/set proxy cert extension.
4958 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
4960 ** Added self-test to test for regressions of pathLenConstraint bug.
4961 Incidentally, this also test (some) other regressions or changes in
4962 the output from certtool --certificate-info.
4964 ** When certtool generates CA certificates, pressing enter on the path
4965 ** length constraint query will now remove the field.
4966 Before it set the path length constraint to 0, which is a rather poor
4969 ** Certtool now print times in UTC when printing certificate/CRL info.
4971 ** Add better fix to work around C++ compiler bug on Mac OS X.
4972 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
4974 ** Fix import of ASCII armored OpenPGP keys.
4975 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
4977 ** Update of gnulib files.
4979 ** API and ABI modifications:
4980 gnutls_x509_crt_set_proxy_dn: ADD.
4981 gnutls_x509_crt_set_proxy: ADD.
4982 gnutls_x509_crt_get_proxy: ADD.
4984 * Version 1.7.2 (released 2007-01-14)
4986 ** Certtool now print the value of the pathLenConstraints field for certs.
4988 ** Certtool now query for path length constraints when generating CA certs.
4989 For batch uses, the certtool configuration name is "path_len".
4990 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
4992 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
4993 The new functions gnutls_x509_crt_get_basic_constraints and
4994 gnutls_x509_crt_set_basic_constraints provide a superset of the
4995 functionality in the old gnutls_x509_crt_get_ca_status and
4996 gnutls_x509_crt_set_ca_status (respectively), but the old functions
4997 will continue to be supported.
4999 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
5000 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
5001 OpenCDK release with this patch will be made soon, which should bump
5002 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
5004 ** Certtool --to-p12 can now store more than one certificate in the blob.
5005 Before it could only store one certificate, but now it will read and
5006 store as many certificate there are from the --load-certificate file.
5007 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5009 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
5010 In particular, the OpenPGP function variables are no longer part of
5011 the exported libgnutls interface, and no header files from
5012 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
5013 were never intended for non-internal purposes, and thus this does not
5014 imply a change in the external API/ABI.
5016 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
5017 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5019 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
5020 Before these parameters were set to make GnuTLS build under mingw32,
5021 however, they appear to no longer be necessary.
5023 ** A minor fix to the C++ library to make it build.
5024 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
5026 ** Update of gnulib files.
5028 ** API and ABI modifications:
5029 gnutls_x509_crt_get_basic_constraints: ADD.
5030 gnutls_x509_crt_set_basic_constraints: ADD.
5031 cdk_pubkey_to_sexp: ADD (in opencdk).
5032 cdk_seckey_to_sexp: ADD (in opencdk).
5034 * Version 1.7.1 (released 2006-12-28)
5036 ** TLS 1.2 server side fix.
5037 The Certificate Request sent did not contain the list of supported
5038 hashes field, thus violating the protocol. It will now contain an
5039 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5041 ** TLS 1.2 DSA signature verification fix.
5042 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5044 ** Fix the list of trusted CAs that server's send to clients.
5045 Before, the list contained issuer DN's instead of subject DN's of the
5046 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5048 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5049 Also added a self-test in tests/certificate_set_x509_crl.c to test the
5050 function. Reported by Max Kellermann <max@duempel.org>.
5052 ** Encode UID fields in DN's as DirectoryString.
5053 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5054 incorrect, it should have used DirectoryString. Now it will use
5055 DirectoryString for the UID field, but for backwards compatibility it
5056 will also accept IA5String UID's. Reported by Max Kellermann
5059 ** Improve out-of-sourcedir builds from CVS.
5060 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5062 ** Bootstrap tools changed.
5063 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
5064 building GnuTLS from CVS. Libtool 1.5.22 is used.
5066 ** Fixed a syntax error in lib/gnutls.asn.
5067 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
5069 ** Added German translation of GnuTLS messages.
5071 ** Update of gnulib files.
5073 ** API and ABI modifications:
5074 No changes since last version.
5076 * Version 1.7.0 (released 2006-11-29)
5078 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
5079 The details is that the protocol priority set by
5080 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
5081 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
5083 ** Preliminary support for TLS 1.2.
5084 The client has been successfully tested against
5085 https://www.mikestoolbox.org:4433/.
5087 ** Anonself test now print a lot of debugging info, including TLS version.
5089 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
5091 ** Update of gnulib files.
5093 ** API and ABI modifications:
5094 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
5096 *** Pulled up from stable 1.6.x branch:
5098 ** Fix ./configure failure with non-GCC compilers.
5099 This fixes the following error message:
5100 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5101 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5103 * Version 1.6.3 (released 2007-05-26)
5105 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
5106 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
5107 from the 1.7.x branch, see
5108 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
5110 ** Have PKCS8 parser return better error codes.

5113 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
5115 ** Fix mem leak for sessions with client authentication via certificates.
5116 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
5117 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
5119 ** Fix building of 'tlsia' self test.
5120 Earlier some gcc are known to build tlsia linking to
5121 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
5122 the build directory, even though command line parameters look OK.
5123 Changing order of some parameters fixes it.
5125 ** API and ABI modifications:
5126 gnutls_x509_crt_get_raw_issuer_dn: ADD.
5127 gnutls_x509_crt_get_raw_dn: ADD.
5129 * Version 1.6.2 (released 2007-04-18)
5131 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
5132 Before, we remove the parameters field, which resulted in a slightly
5133 different DER encoding which in turn caused signature verification
5134 failures of GnuTLS-generated RSA certificates in some other
5135 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
5136 you read, this may or may not be correct, but our new behaviour appear
5137 to be consistent with other widely used implementations.
5139 ** Regenerate the PKIX ASN.1 syntax tree.
5140 For some reason, after changing the ASN.1 type of ldap-UID in the last
5141 release, the generated C file built from the ASN.1 schema was not
5142 refreshed. This can cause problems when reading/writing UID
5143 components inside X.500 Distinguished Names. Reported by devel
5144 <dev001@pas-world.com>.
5146 ** Updated translations.
5148 ** API and ABI modifications:
5149 No changes since last version.
5151 * Version 1.6.1 (released 2006-12-28)
5153 ** Fix the list of trusted CAs that server's send to clients.
5154 Before, the list contained issuer DN's instead of subject DN's of the
5155 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5157 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5158 Reported by Max Kellermann <max@duempel.org>.
5160 ** Encode UID fields in DN's as DirectoryString.
5161 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5162 incorrect, it should have used DirectoryString. Now it will use
5163 DirectoryString for the UID field, but for backwards compatibility it
5164 will also accept IA5String UID's. Reported by Max Kellermann
5167 ** Fix ./configure failure with non-GCC compilers.
5168 This fixes the following error message:
5169 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5170 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5172 ** API and ABI modifications:
5173 No changes since last version.
5175 * Version 1.6.0 (released 2006-11-17)
5177 ** No changes since 1.5.5.
5178 The major changes compared to the 1.4.x branch are:
5180 *** A GnuTLS C++ library is part of the official distribution.
5181 Currently there are no examples or documentation, but hopefully this
5182 will change. See gnutlsxx.h for the API.
5184 *** Windows is a supported platform.
5185 There are, however, two know bugs. One is related to select() in
5186 command line tools (not, nota bene, in the library), the other is a
5187 problem with libgcrypt that causes delays. Help is needed to resolve
5188 those issues, so we feel we can't delay the release because of this.
5190 *** New APIs for custom push/pull function error reporting.
5191 The new APIs are gnutls_transport_set_errno and
5192 gnutls_transport_set_global_errno. See the release notes for version
5193 1.5.4 for more information.
5195 *** Self tests are run under valgrind, if available. See --disable-valgrind.
5197 * Version 1.5.5 (released 2006-11-16)
5199 ** Correctly bump shared library version after adding new APIs.
5200 This was forgotten in the last release.
5202 ** Fix unsigned vs signed problem in ex-x509-info.c example.
5203 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
5205 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
5207 ** Update of gnulib files.
5209 ** API and ABI modifications:
5210 No changes since last version.
5212 * Version 1.5.4 (released 2006-11-07)
5214 ** New API functions to set errno in push/pull functions.
5215 Under Windows, setting the errno variable in a push/pull replacement
5216 may end up setting the wrong errno variable, and GnuTLS send/recv
5217 functions become confused about the real errno returned from a failed
5218 push/pull function. Therefor, we have added two APIs to set the errno
5219 variable used by GnuTLS. The APIs can also help to keep things
5220 thread-safe, by avoiding potentially global variables. Typically,
5221 instead of setting errno in your push/pull function, you will call one
5222 of these functions. It is recommended to use
5223 gnutls_transport_set_errno, but if you don't have the session variable
5224 easily accessible in the push/pull replacement function, you can use
5225 gnutls_transport_set_global_errno. Suggested by Tim Kosse
5226 <tim.kosse@filezilla-project.org>.
5228 void gnutls_transport_set_errno (gnutls_session_t session, int err);
5229 void gnutls_transport_set_global_errno (int err);
5231 ** When calling `recv' or `send' Windows errors are handled properly.
5232 The Windows recv/send functions doesn't use errno, and GnuTLS now use
5233 WSAGetLastError to access the error condition instead.
5235 ** Several OpenPGP API fixes.
5236 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
5237 important fix is to change the return value of
5238 gnutls_openpgp_privkey_get_pk_algorithm and
5239 gnutls_openpgp_key_get_pk_algorithm from 'int' to
5240 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
5241 compatible with 'int').
5243 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5244 ** version, try to negotiate the highest version support by the GnuTLS server,
5245 ** instead of the lowest.
5246 Reported by <Pasi.Eronen@nokia.com>.
5248 ** Replace old constructs with use of gnulib modules.
5249 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
5250 the code. If the headers doesn't exist on the target system, gnulib
5251 will make sure its replacement header files are used instead.
5253 ** Fix SOVERSION computation for *.def files.
5254 This fixes build errors similar to "No rule to make target
5255 `libgnutls-`expr', needed by `all-am'." when building for Windows.
5257 ** gnutls_check-version uses strverscmp from gnulib.
5259 ** Update of gnulib files.
5261 ** API and ABI modifications:
5262 gnutls_transport_set_errno: ADD
5263 gnutls_transport_set_global_errno: ADD
5265 * Version 1.5.3 (released 2006-10-26)
5267 ** Add new self-test of RSA-MD5 signature chains.
5268 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
5269 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
5270 and is based on the work by Marc Stevens et al, see
5271 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
5273 ** Re-factor self tests.
5275 ** The include copy of Libtasn1 is updated to version 0.3.7.
5277 ** The included copy of OpenCDK is updated to version 0.5.11.
5279 ** Fix the filename of the *.def file on Windows after library version bump.
5281 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
5282 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
5283 gnulib modules. Earlier we could only use the LGPL'ed module from
5284 gnulib, because two gnulib directories in the same project didn't
5287 ** API and ABI modifications:
5288 No changes since last version.
5290 * Version 1.5.2 (released 2006-10-03)
5292 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
5293 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
5294 shared library version than this version, so you'll have to remove
5295 them and possibly relink your applications. The reason for this is
5296 that no API/ABI changes have been made since the 1.4.x branch, and
5297 that incrementing the shared library version was a mistake. Reported
5298 by Andreas Metzler <ametzler@downhill.at.eu.org>.
5300 ** Fix off-by-one error when computing length to malloc.
5301 The code is used by gnutls_openpgp_add_keyring_file and
5302 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
5303 <agl@imperialviolet.org>.
5305 ** Add version script for the GnuTLS C++ library.
5306 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5308 ** Fix the C++ compiler detection logic.
5309 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5311 ** Update of gnulib files.
5313 ** API and ABI modifications:
5314 No changes since last version.
5316 * Version 1.5.1 (released 2006-09-21)
5318 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5319 ** Crypto 06 rump session attack.
5320 In particular, we check that the digestAlgorithm.parameters field is
5321 missing or empty, to avoid that it can contain "garbage" that may be
5322 used to alter the numeric properties of the signature. See
5323 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
5324 not exactly the same as the problem we fix here). Reported by Yutaka
5325 OIWA <y.oiwa@aist.go.jp>.
5327 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
5328 up to date information.
5330 ** Add self test to test for above flaw.
5332 ** Fix gnutls-cli-debug regarding resume support detection.
5333 Earlier, if the session-id from the server had a length of 0, it would
5334 indicate that the server supports resumption, which isn't the case.
5335 Reported by Kataja Kai <kai.kataja@op.fi>.
5337 ** Fix building of examples on FreeBSD by including netinet/in.h.
5338 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
5340 ** Fix certtool bug that caused the private key to not be loaded when
5341 generating a certificate with --load-request, which in turn triggered
5342 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
5343 by Sascha Ziemann <sascha.ziemann@secunet.com>.
5345 ** gnutls-cli and gnutls-serv works on Windows.
5346 The problem was the select() call that doesn't work on file
5347 descriptors (stdin) on Windows. We borrowed some code from plibc to
5348 solve this. It appears to be somewhat unreliable though.
5350 ** Autoconf 2.60 is now used.
5352 ** API and ABI modifications:
5353 No changes since last version.
5355 * Version 1.5.0 (released 2006-08-13)
5357 ** Change SRP and Cert-Type extensions to match IANA registry.
5359 ** Fixed bug in OpenPGP authentication handshake.
5361 ** Improvements for building under MinGW.
5362 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
5363 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
5364 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
5365 at run-time from ws2_32.dll, and falls back on a simple replacement if
5366 it is not available. Builds the library with -mms-bitfields
5367 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
5368 create *.def files, which are installed.
5370 ** The examples now (conditionally) include config.h and link to gnulib.
5371 No other source changes were necessary, so the examples should
5372 continue to be possible to use stand-alone without any autoconf or
5375 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
5376 You may unconditionally disable it with --disable-cxx. See
5377 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
5380 ** Made command line tool '--version' behave according to GNU Standards.
5381 This enables 'make distcheck' to succeed.
5383 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5385 ** Make --without-included-libtasn1 work.
5386 Reported by Daniel Black <dragonheart@gentoo.org>.
5388 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5389 See http://www.gnu.org/software/gnutls/security.html regardging

5391 satyakumar <satyam_kkd@hyd.hellosoft.com>.
5393 ** API and ABI modifications:
5394 No changes since last version.
5396 * Version 1.4.5 (released 2006-11-06)
5398 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5399 ** version, try to negotiate the highest version support by the GnuTLS server,
5400 ** instead of the lowest.

5406 ** API and ABI modifications:
5407 No changes since last version.
5409 * Version 1.4.4 (released 2006-09-12)
5411 ** Relax the test that caught signatures that exploit the variant of
5412 ** Bleichenbacher's Crypto 06 rump session attack on our
5413 ** verification logic flaw.
5414 In particular, we now permit the digestAlgorithm.parameters field to
5415 be present but empty, whereas in 1.4.3 we actually checked that the
5418 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
5419 The messages are only printed in debug mode, which is not recommended
5420 for normal use, and thus logging this situation cannot be abused as an
5421 oracle in typical recommended situations.
5423 ** API and ABI modifications:
5424 No changes since last version.
5426 * Version 1.4.3 (released 2006-09-08)
5428 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5429 ** Crypto 06 rump session attack.
5430 In particular, we check that the digestAlgorithm.parameters field is
5431 empty, to avoid that it can contain "garbage" that may be used to
5432 alter the numeric properties of the signature. See

5449 ** API and ABI modifications:
5450 No changes since last version.
5452 * Version 1.4.2 (released 2006-08-12)
5454 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5455 This can happen if you call gnutls_certificate_verify_peers2 and have
5456 a certain mix of local CA certificates and the peer send special
5457 certificates, that together trigger certain behaviour. It is not
5458 known at this point whether the crash can be triggered without the
5459 special local CA certificate, and thus turn this into a remote crash
5460 of clients that verify server certificates when they talk to a server
5461 with the special server certificate. See GNUTLS-SA-2006-2 on
5462 http://www.gnu.org/software/gnutls/security.html for more up to date
5463 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
5465 ** Change SRP and Cert-Type extensions to match IANA registry.
5467 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5469 ** Make --without-included-libtasn1 work.
5470 Reported by Daniel Black <dragonheart@gentoo.org>.
5472 ** API and ABI modifications:
5473 No changes since last version.
5475 * Version 1.4.1 (released 2006-06-14)
5477 ** Replaced inactive ifdefs to enable openpgp support in test programs.
5479 ** Fixed bug in OpenPGP authentication handshake.
5481 ** Fixed typographical in man pages.
5483 ** Build fixes of the manual.
5485 ** Added Swedish translation.
5487 ** API and ABI modifications:
5488 No changes since last version.
5490 * Version 1.4.0 (released 2006-05-15)
5492 ** Remove GnuTLS 0.8.x compatibility functions.
5494 ** The libgcrypt RNG is initialized in gnutls_global_init().
5496 ** TLS/IA API changes from Emile van Bergen.
5497 A dummy credential structure is not needed now, if you wish to use the
5498 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
5501 ** The self-tests are now run under valgrind, if it is installed.
5503 ** Libtasn1 is updated to 0.3.4, and that version is now required.
5505 ** The command line tools now use getaddrinfo and support IPv6.
5507 ** API and ABI modifications:
5508 _gnutls_x509_get_raw_crt_activation_time,
5509 _gnutls_x509_get_raw_crt_expiration_time: Removed.
5510 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
5511 gnutls_ia_enable: Added.
5513 * Version 1.3.5 (released 2006-03-08)
5515 ** Error messages are now translated using GNU Gettext.
5517 ** The function gnutls_x509_crt_to_xml now return an internal error.
5518 This means that the code to convert X.509 certificates to XML format
5519 does not work any more. The reason is that the function called
5520 libtasn1 internal functions. It seems unclean for libtasn1 to export
5521 the APIs needed here. Instead it would be better to implement XML
5522 support inside libtasn1 properly. If you need this functionality
5523 strongly, please consider looking into implementing this suggested
5524 approach instead. As a workaround, you may also modify lib/x509/xml.c
5525 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
5527 ** Libraries are now built with libtool's -no-undefined.
5528 This helps producing libraries for Windows using mingw32.
5530 ** Doc fixes to explain that gnutls_record_send can block.
5532 ** Libtasn1 0.3.1 or later is now required.
5533 The include copy has been updated too.
5535 ** gnutls-cli can now recognize services and port numbers with the -p option.
5537 ** API and ABI modifications:
5538 No changes since last version.
5540 * Version 1.3.4 (released 2006-02-09)
5542 ** Fix read of out bounds bug in DER parser.
5543 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
5544 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
5545 previous bug fix. The included libtasn1 version in GnuTLS has been
5548 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5549 longer invalidate a session if the underlying send fails, but it will
5550 prevent future writes. That is to allow reading the already received data.
5551 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5553 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
5554 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5555 more than one certificates were added. Report and patch by Max Kellermann.
5557 ** Fix build problems of OpenCDK on AIX.
5558 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
5560 ** API and ABI modifications:
5561 No changes since last version.
5563 * Version 1.3.3 (released 2006-01-12)
5565 ** New API to access the TLS master secret.
5566 When possible, you should use the TLS PRF functions instead.
5567 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5569 ** Improved handling when multiple libraries use GnuTLS at the same time.
5570 Now gnutls_global_init() can be called multiple times, and
5571 gnutls_global_deinit() will only deallocate the structure when it has
5572 been called as many times as gnutls_global_init() was called.
5574 ** Added a self test of TLS resume functionality.
5576 ** Fix crash in TLS resume code, caused by TLS/IA changes.
5578 ** Documentation fixes about thread unsafety, prompted by
5579 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
5580 In particular, gnutls_global_init() and gnutls_global_deinit() are not
5581 thread safe. Careful callers may want to protect the call using a
5582 mutex. The problem could also be ignored, which would cause a memory
5583 leak under rare conditions when two threads invoke the function
5584 roughly at the same time.
5586 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
5588 ** The code was indented again, including the external header files.
5590 ** API and ABI modifications:
5591 New functions to retrieve the master secret value:
5592 gnutls_session_get_master_secret
5594 Add a 'const' keyword to existing API:
5595 gnutls_x509_crq_get_challenge_password
5597 * Version 1.3.2 (released 2005-12-15)
5599 ** GnuTLS now support TLS Inner application (TLS/IA).
5600 This is per draft-funk-tls-inner-application-extension-01. This
5601 functionality is added to libgnutls-extra, so it is licensed under the
5602 GNU General Public License.
5604 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
5605 The PRF is used by some protocols building on TLS, such as EAP-PEAP
5606 and EAP-TTLS. One function to access the raw PRF and one to access
5607 the PRF seeded with the client/server random fields are provided.
5608 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5610 ** New APIs to acceess the client and server random fields in a session.
5611 These fields can be useful by protocols using TLS. Note that these
5612 fields are typically used as input to the TLS PRF, and if this is your
5613 intended use, you should use the TLS PRF API that use the
5614 client/server random field directly. Suggested by Jouni Malinen
5615 <jkmaline@cc.hut.fi>.
5617 ** Internal type cleanups.
5618 The uint8, uint16, uint32 types have been replaced by uint8_t,
5619 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
5620 correct types on platforms that lack them. The uint type have been
5621 replaced by unsigned.
5623 ** API and ABI modifications:
5624 New functions to invoke the TLS Pseudo-Random-Function (PRF):
5628 New functions to retrieve the session's client and server random values:
5629 gnutls_session_get_server_random
5630 gnutls_session_get_client_random
5632 New function, to perform TLS/IA handshake:
5635 New function to decide whether to do a TLS/IA handshake:
5636 gnutls_ia_handshake_p

5649 gnutls_ia_set_server_avp_ptr
5650 gnutls_ia_get_server_avp_ptr
5652 New functions, to toggle TLS/IA application phases:
5653 gnutls_ia_require_inner_phase
5655 New function to mix session keys with inner secret:
5656 gnutls_ia_permute_inner_secret
5658 Low-level API (used internally by gnutls_ia_handshake):
5659 gnutls_ia_endphase_send
5663 New functions that can be used after successful TLS/IA negotiation:

5675 GNUTLS_A_INNER_APPLICATION_VERIFICATION
5677 New error codes, to signal when an application phase has finished:
5678 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
5679 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
5681 New error code to signal TLS/IA verify failure:
5682 GNUTLS_E_IA_VERIFY_FAILED
5684 * Version 1.3.1 (released 2005-12-08)
5686 ** Support for DHE-PSK cipher suites has been added.
5687 This method offers perfect forward secrecy.
5689 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5690 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5692 ** Corrected a bug in certtool for 64 bit machines. Reported
5693 by Max Kellermann <max@duempel.org>.
5695 ** New function to set a X.509 private key and certificate pairs, and/or
5696 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
5697 <emile@e-advies.nl>.
5699 The integrity of the PKCS#12 file is protected through a password
5700 based MAC; public-key based signatures for integrity protection are
5701 not supported. PKCS#12 bags may be encrypted using password derived
5702 symmetric keys, public-key based encryption is not supported. The
5703 PKCS#8 keys may be encrypted using passwords. The API use the same
5704 password for all operations. We believe that any more flexibility
5705 create too much complexity that would hurt overall security, but may
5706 add more PKCS#12 related APIs if real-world experience indicate
5709 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
5710 reported by Emile van Bergen <emile@e-advies.nl>.
5711 This will enable "certtool -k -8" to parse those keys.
5713 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
5714 Use "certtool -p -8" and press press enter at the prompt. Earlier,
5715 certtool would have encrypted the key using an empty password.
5717 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
5718 Earlier it would have prompted the user for it, even if --password was
5721 ** Added self test of PKCS#8 parsing.
5722 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
5723 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
5726 ** API and ABI modifications:
5727 New function to set X.509 credentials from a PKCS#12 file:
5728 gnutls_certificate_set_x509_simple_pkcs12_file
5730 New gnutls_kx_algorithm_t enum type:
5733 New API to return session data (basically same as gnutls_session_get_data):
5734 gnutls_session_get_data2
5736 New API to set PSK Diffie-Hellman parameters:
5737 gnutls_psk_set_server_dh_params
5739 * Version 1.3.0 (2005-11-15)
5741 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
5742 This add several new APIs, see below. Read the updated manual for
5743 more information. A new self test "pskself" has been added, that will
5744 test this functionality.
5746 ** The session resumption data are now system independent.
5748 ** The code has been re-indented to conform to the GNU coding style.
5750 ** Removed the RIPEMD ciphersuites.
5752 ** Added a discussion of the internals of gnutls in manual.
5754 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
5756 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
5758 ** Make sure config.h is included first in a few files, from Albert Chin.
5760 ** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
5762 ** Don't install SRP programs and man pages if --disable-srp-authentication,
5765 ** API and ABI modifications:
5766 New gnutls_kx_algorithm_t key exchange type: GNUTLS_KX_PSK
5768 New gnutls_credentials_type_t credential type:
5771 New credential types:
5772 gnutls_psk_server_credentials_t
5773 gnutls_psk_client_credentials_t
5775 New functions to allocate PSK credentials:
5776 gnutls_psk_allocate_client_credentials
5777 gnutls_psk_free_client_credentials
5778 gnutls_psk_free_server_credentials
5779 gnutls_psk_allocate_server_credentials
5781 New enum type for PSK key flags:
5782 gnutls_psk_key_flags
5784 New function prototypes for credential callback:
5785 gnutls_psk_client_credentials_function
5786 gnutls_psk_server_credentials_function
5788 New function to set PSK username and key:
5789 gnutls_psk_set_client_credentials
5791 New function to set PSK passwd file:
5792 gnutls_psk_set_server_credentials_file
5794 New function to extract PSK user in server:
5795 gnutls_psk_server_get_username
5797 New functions to set PSK callback:
5798 gnutls_psk_set_server_credentials_function
5799 gnutls_psk_set_client_credentials_function
5801 Use size_t instead of int for output size parameter:
5802 gnutls_srp_base64_encode
5803 gnutls_srp_base64_decode
5805 * Version 1.2.11 (2006-05-11)
5806 - The function gnutls_x509_crt_to_xml is not supported any more, and
5807 return an internal error. The reason is that the function called
5808 internal libtasn1 functions which are no longer exported from
5810 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
5811 - Updated gnulib compatibility files.
5812 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
5813 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
5814 - API and ABI modifications:
5815 No changes since last version.
5817 * Version 1.2.10 (2006-02-09)
5818 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
5819 <admin@gleg.net>, and debugging help from Protover SSL.
5820 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
5821 The included version has been updated too.
5822 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5823 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5824 - Corrected a bug in certtool for 64 bit machines. Reported
5825 by Max Kellermann <max@duempel.org>.
5826 - Corrected bugs in gnutls_certificate_set_x509_crl() and
5827 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5828 more than one certificates were added. Report and patch by Max Kellermann.
5829 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5830 longer invalidate a session if the underlying send fails, but it will
5831 prevent future writes. That is to allow reading the already received data.
5832 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5834 * Version 1.2.9 (2005-11-07)
5835 - Documentation was updated and improved.
5836 - RSA-MD2 is now supported for verifying digital signatures.
5837 - Due to cryptographic advances, verifying untrusted X.509
5838 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
5839 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
5840 applications that must remain interoperable, you can use the
5841 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
5842 flags when verifying certificates. Naturally, this is not
5843 recommended default behaviour for applications. To enable the
5844 broken algorithms, call gnutls_certificate_set_verify_flags with the
5845 proper flag, to change the verification mode used by
5846 gnutls_certificate_verify_peers2.
5847 - Make it possible to send empty data through gnutls_record_send,
5848 to align with the send(2) API.
5849 - Some changes in the certificate receiving part of handshake to prevent
5850 some possible errors with non-blocking servers.
5851 - Added numeric version symbols to permit simple CPP-based feature
5852 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
5853 - The (experimental) low-level crypto alternative to libgcrypt used
5854 earlier (Nettle) has been replaced with crypto code from gnulib.
5855 This leads to easier re-use of these components in other projects,
5856 leading to more review and simpler maintenance. The new configure
5857 parameter --with-builtin-crypto replace the old --with-nettle, and
5858 must be used if you wish to enable this functionality. See README
5859 under "Experimental" for more information. Internally, GnuTLS has
5860 been updated to use the new "Generic Crypto" API in gl/gc.h. The
5861 API is similar to the old crypto/gc.h, because the gnulib code were
5862 based on GnuTLS's gc.h.
5863 - Fix compiler warning in the "anonself" self test.
5864 - API and ABI modifications:
5865 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
5866 This doesn't reflect a change in behaviour,
5867 so we don't break backwards compatibility.
5868 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
5869 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
5870 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
5871 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
5873 gnutls_x509_crt_list_verify,
5874 gnutls_x509_crt_verify, or
5875 gnutls_certificate_set_verify_flags.
5876 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
5877 used when broken signature algorithms
5878 is used (currently RSA-MD2/MD5).
5879 LIBGNUTLS_VERSION_MAJOR,
5880 LIBGNUTLS_VERSION_MINOR,
5881 LIBGNUTLS_VERSION_PATCH,
5882 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
5883 version number, can be used for feature existence
5886 * Version 1.2.8 (2005-10-07)
5887 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
5888 - Don't install the auxilliary libexamples library used by the
5889 examples in doc/examples/ on "make install", report and tiny patch
5890 from Thomas Klausner <tk@giga.or.at>.
5891 - If you pass a X.509 CA or PGP trust database to the command line
5892 tool, it will now abort the connection if the server certificate
5893 validation fails. Use the parameter --insecure to continue even
5894 after certificate validation failures. Inspired from discussion
5895 with Alexander Kotelnikov <sacha@myxomop.com>.
5896 - The test for socklen_t has been moved to gnulib.

5954 - Corrected some bugs that could affect 64 bit systems.
5955 - Some corrections in the header files to include the prototype
5956 of memmem properly (affected 64 bit systems). Report and patch
5957 by Yoann Vandoorselaere <yoann@prelude-ids.org>.
5958 - Introduced the --fix-key option to certtool, which can be used to
5959 regenerate the (optional) parameters in a private key. It should
5960 be used together with --key-info.
5961 - Corrected a bug in certificate chain verification that could lead
5962 to marking a trusted chain as non trusted, if the last certificate in
5963 the chain was a self signed one.
5964 - Gnulib portability files were updated.
5965 - License were updated to reflect new FSF address.

5981 - Fixed pkcs12 friendly name and local key identifier decoding.
5982 - Internal cleanups, removed duplicate typedef/struct definitions,
5983 and made source code include external include file, to check
5984 function prototypes during compile time.
5985 - API and ABI modifications:

5994 are not in the included list.
5995 - Added warning to certtool when MD5 is being used for digital
5997 - Optimizations ("-O2 -finline-functions") are not enabled by default,
5998 instead the standard autoconf defaults are used. Use `./configure
5999 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
6000 - Added the option --get-dh-params to certtool, in order to get the
6001 parameters included in the library primes and generators.
6002 - Improved the semantics of GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT, to
6003 allow only trusted Version 1 CAs and introduced

6005 - Nettle self tests now build properly, reported by Pierre
6006 <pierre42d@9online.fr>.
6007 - Eliminated some memory leaks in DHE and RSA-EXPORT cipher suites.
6008 Reported by Yoann Vandoorselaere <yoann@prelude-ids.org>.
6009 - If the library has been compiled with features disabled, a warning is
6010 issued during the compilation of any program.
6011 - API and ABI modifications:

6037 gnutls_x509_rdn_get now set *sizeof_buf to the buffer length that is
6038 required, instead of the string length. That is, the value has been
6039 incremented by 1 to account for the terminating zero. Reported by
6040 Martin Lambers <marlam@web.de>.
6041 - Debug output shouldn't crash on platforms that doesn't handle NULL
6042 printf %s values. Reported by Michael.Ringe@aachen.utimaco.de.
6043 - Sync included copy of libtasn1 with version 0.2.13.

6084 a key and no certificate to PKCS#12.
6085 - Fix objdir != srcdir builds, reported by "Gerrit P. Haase"
6086 <gp@familiehaase.de>.
6087 - Fixes faulty getpass implementation in libextra/opencdk/, reported
6088 by Yoann Vandoorselaere <yoann@prelude-ids.org>.
6089 - Uses memmem instead of strnstr in lib/.
6090 - Using more GNULib portability files, although not yet inside lib/.
