6 * Version 1.7.10 (released 2007-05-25)
8 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
9 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
11 ** Update of gnulib files.
13 ** GnuTLS is now developed in GIT instead of CVS.
14 See <http://repo.or.cz/w/gnutls.git> for a public repository.
16 ** API and ABI modifications:
17 gnutls_x509_crt_get_raw_issuer_dn: ADD.
18 gnutls_x509_crt_get_raw_dn: ADD.
20 * Version 1.7.9 (released 2007-05-12)
22 ** X.509 certificates are preferred over OpenPGP keys.
23 This is a change in the semantics of gnutls_set_default_priority.
25 ** The included copy of OpenCDK has been updated to 0.6.1.
26 There has been some API changes in OpenCDK, and the GnuTLS layer have
27 been modified as well. Note that while there are API/ABI incompatible
28 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
29 its API/ABI have not changed. From this version on, GnuTLS requires
30 OpenCDK 0.6.0 or later.
32 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
34 ** Change certtool's default serial number from 0 to a time-based value.
36 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
37 Before, we remove the parameters field, which resulted in a slightly
38 different DER encoding which in turn caused signature verification
39 failures of GnuTLS-generated RSA certificates in some other
40 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
41 you read, this may or may not be correct, but our new behaviour appear
42 to be consistent with other widely used implementations.
44 ** Fix mem leaks in gnutls_x509_crt_print.
46 ** API and ABI modifications:
47 No changes since last version.
49 * Version 1.7.8 (released 2007-04-16)
51 ** Added examples for the authorization extension.
52 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
54 ** The examples only use gnutls_set_default_priority().
55 The exception is when DH_ANON is needed.
57 ** Improve gnutls_set_default_priority() priorities.
58 The new approach is for it to try and negotiate all secure and
59 standard mechanisms available. Currently, DH_ANON ciphersuites and
60 LZO compressions are not enabled by default, because they are,
61 respectively, insecure and non-standardized. Note that TLS 1.2 will
62 not be enabled by default in non-experimental release until it has
63 been approved by the IETF.
65 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
66 This means that to get DH_ANON and LZO compression, you'll need to
67 specify that manually using '--kx anon' or '--comp lzo'.
69 ** Minor fixes to the human display format of X.509 certificates.
71 ** New APIs to extract Distinguished Name's from X.509 certificates.
72 Based on patch from Howard Chu <hyc@symas.com>.
74 ** Improved library searching for opencdk.
75 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
76 The deprecated opencdk.m4 is no longer used.
78 ** New APIs to list supported algorithms in the library.
79 The APIs are gnutls_cipher_list, gnutls_mac_list,
80 gnutls_compression_list, gnutls_protocol_list,
81 gnutls_certificate_type_list, gnutls_kx_list, and
82 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
84 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
86 ** New configure option --disable-tls-authorization to disable tls-authz.
88 ** Fix prototype for `gnutls_psk_set_client_credentials'.
89 The last parameter was renamed from 'flags' to 'format' and the type
90 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
91 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
94 ** Fix allocation in gnutls_certificate_set_openpgp_key.
95 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
97 ** API and ABI modifications:
98 gnutls_x509_dn_t: ADD.
99 gnutls_x509_ava_st: ADD.
100 gnutls_x509_crt_get_subject,
101 gnutls_x509_crt_get_issuer: ADD.
102 gnutls_x509_dn_get_rdn_ava: ADD.
103 gnutls_cipher_list: ADD.
104 gnutls_mac_list: ADD.
105 gnutls_compression_list: ADD.
106 gnutls_protocol_list: ADD.
107 gnutls_certificate_type_list: ADD.
109 gnutls_cipher_suite_info: ADD.
111 * Version 1.7.7 (released 2007-02-22)
113 ** Support for supplemental handshake messages and authorization data.
114 Supplemental data is described in RFC 4680 and the authorization
115 extensions in draft-housley-tls-authz-extns-07.
117 ** Support for authorization data in gnutls-cli and gnutls-serv.
118 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
120 ** Fix for gnutls_x509_crt_check_hostname.
121 Before it would have reported that the certificate matched a hostname
122 when it did not have any dNSName or any CN field. Report and tiny
123 patch from "Richard W.M. Jones" <rjones@redhat.com>.
125 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
126 Tests regressions of the bug, and several other features.
128 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
129 Before there were no support for iPAddress SAN's during comparison.
131 ** New API to print information about CRL's.
132 The function is gnutls_x509_crl_print.
134 ** New API to extract signature value from CRL's.
135 The function is gnutls_x509_crl_get_signature.
137 ** Support for directoryName Subject Alternative Name's.
138 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
139 string in the provided buffer.
141 ** Internal improvements to certtool.
142 It uses gnutls_x509_crl_print to print CRL information. It uses some
143 more gnulib modules to simplify error handling.
145 ** API and ABI modifications:
146 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
147 gnutls_supplemental_data_format_type_t: ADD.
148 gnutls_authz_data_format_type_t: ADD.
149 gnutls_supplemental_get_name: ADD.
150 gnutls_authz_recv_callback_func,
151 gnutls_authz_send_callback_func: ADD, callback prototypes.
152 gnutls_authz_enable: ADD.
153 gnutls_authz_send_x509_attr_cert,
154 gnutls_authz_send_saml_assertion,
155 gnutls_authz_send_x509_attr_cert_url,
156 gnutls_authz_send_saml_assertion_url: ADD.
157 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
158 gnutls_x509_crl_print: ADD.
159 gnutls_x509_crl_get_signature: ADD.
161 * Version 1.7.6 (released 2007-02-12)
163 ** Support for 'otherName' Subject Alternative Names.
164 The existing API gnutls_x509_crt_get_subject_alt_name may now return
165 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
166 To find out the otherName OID (necessary for proper parsing of the
167 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
168 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
169 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
170 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
172 ** Certtool can print otherName SAN values for certificates.
173 For known otherName OIDs (currently only id-on-xmppAddr as defined by
174 RFC 3920), it will also print the name.
176 ** Fix TLS 1.2 RSA signing in servers.
177 Before it used the old-style MD5+SHA1 signature, but the TLS
178 signatures should be normal PKCS#1 signatures. FYI, we use and
179 require that DigestInfo parameters are present and NULL for TLS 1.2.
181 ** Add APIs to access X.509 extensions sequentially.
182 The existing APIs gnutls_x509_crt_get_extension_oid() and
183 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
184 inspect the extensions in the order defined by the certificate.
186 ** Add API to extract signature value from X.509 certificates.
187 The function is gnutls_x509_crt_get_signature.
189 ** Fix crash when generating proxy certificates in batch mode.
190 If you don't specify a proxy policy in batch mode, it will use
193 ** Add API to print information about X.509 certificates.
194 The function is gnutls_x509_crt_print.
196 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
197 One consequence of this is that the output syntax has changed
198 slightly. Some more fields are printed.
202 ** API and ABI modifications:
203 gnutls_x509_crt_print: ADD
204 gnutls_certificate_print_formats_t: ADD, new enum.
205 gnutls_x509_crt_get_signature: ADD.
206 gnutls_x509_crt_get_extension_data: ADD.
207 gnutls_x509_crt_get_extension_info: ADD.
208 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
209 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
210 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
212 * Version 1.7.5 (released 2007-02-06)
214 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
217 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
219 ** Fix --list output for gnutls-cli and gnutls-serv.
220 Mention TLS1.2, SHA512 etc.
222 ** Manual contains new section on setting up a test HTTP server.
223 A server set up following those descriptions are available online via
224 <http://www.gnutls.org/server.html>.
226 ** Update of gnulib files.
228 ** API and ABI modifications:
229 No changes since last version.
231 * Version 1.7.4 (released 2007-02-05)
233 ** Support for RSA signing using SHA-256/384/512.
234 A new self test "sha2" tries to build a long X.509 certificate chain
235 testing all new hashes.
237 ** The gnutls-serv tool now use static DH parameters if none are supplied.
239 ** Discuss proxy certificates in the manual.
241 ** Improve bibliographical citations in the manual.
243 ** Update of gnulib files.
245 ** Fix certtool template handling of pathLenConstraints.
246 It now defaults to -1 instead of 0, which causes the field to be
247 missing unless the template specify it.
249 ** API and ABI modifications:
252 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
255 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
256 GNUTLS_SIGN_RSA_SHA256,
257 GNUTLS_SIGN_RSA_SHA384,
258 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
260 * Version 1.7.3 (released 2007-02-01)
262 ** New option to certtool: --generate-proxy.
263 This will generate a Proxy Certificate from an end entity certificate.
264 Proxy Certificates are documented in RFC 3820. You will need to
265 specify the proxy certificate's private key with --load-privkey, the
266 user certificate with --load-certificate and the private key used to
267 sign the new proxy certificate with --load-ca-privkey. Certtool will
268 query for proxy path length and the policy language OID. Currently
269 only OIDs that have an empty policy are supported (which includes the
270 two OIDs defined by RFC 3820).
272 ** Certtool --certificate-info now prints information for Proxy Certificates.
273 Before the proxy extension was just printed as DER encoded data.
275 ** New APIs to set proxy subject names and get/set proxy cert extension.
277 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
279 ** Added self-test to test for regressions of pathLenConstraint bug.
280 Incidentally, this also test (some) other regressions or changes in
281 the output from certtool --certificate-info.
283 ** When certtool generates CA certificates, pressing enter on the path
284 ** length constraint query will now remove the field.
285 Before it set the path length constraint to 0, which is a rather poor
288 ** Certtool now print times in UTC when printing certificate/CRL info.
290 ** Add better fix to work around C++ compiler bug on Mac OS X.
291 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
293 ** Fix import of ASCII armored OpenPGP keys.
294 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
296 ** Update of gnulib files.
298 ** API and ABI modifications:
299 gnutls_x509_crt_set_proxy_dn: ADD.
300 gnutls_x509_crt_set_proxy: ADD.
301 gnutls_x509_crt_get_proxy: ADD.
303 * Version 1.7.2 (released 2007-01-14)
305 ** Certtool now print the value of the pathLenConstraints field for certs.
307 ** Certtool now query for path length constraints when generating CA certs.
308 For batch uses, the certtool configuration name is "path_len".
309 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
311 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
312 The new functions gnutls_x509_crt_get_basic_constraints and
313 gnutls_x509_crt_set_basic_constraints provide a superset of the
314 functionality in the old gnutls_x509_crt_get_ca_status and
315 gnutls_x509_crt_set_ca_status (respectively), but the old functions
316 will continue to be supported.
318 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
319 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
320 OpenCDK release with this patch will be made soon, which should bump
321 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
323 ** Certtool --to-p12 can now store more than one certificate in the blob.
324 Before it could only store one certificate, but now it will read and
325 store as many certificate there are from the --load-certificate file.
326 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
328 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
329 In particular, the OpenPGP function variables are no longer part of
330 the exported libgnutls interface, and no header files from
331 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
332 were never intended for non-internal purposes, and thus this does not
333 imply a change in the external API/ABI.
335 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
336 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
338 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
339 Before these parameters were set to make GnuTLS build under mingw32,
340 however, they appear to no longer be necessary.
342 ** A minor fix to the C++ library to make it build.
343 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
345 ** Update of gnulib files.
347 ** API and ABI modifications:
348 gnutls_x509_crt_get_basic_constraints: ADD.
349 gnutls_x509_crt_set_basic_constraints: ADD.
350 cdk_pubkey_to_sexp: ADD (in opencdk).
351 cdk_seckey_to_sexp: ADD (in opencdk).
353 * Version 1.7.1 (released 2006-12-28)
355 ** TLS 1.2 server side fix.
356 The Certificate Request sent did not contain the list of supported
357 hashes field, thus violating the protocol. It will now contain an
358 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
360 ** TLS 1.2 DSA signature verification fix.
361 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
363 ** Fix the list of trusted CAs that server's send to clients.
364 Before, the list contained issuer DN's instead of subject DN's of the
365 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
367 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
368 Also added a self-test in tests/certificate_set_x509_crl.c to test the
369 function. Reported by Max Kellermann <max@duempel.org>.
371 ** Encode UID fields in DN's as DirectoryString.
372 Before GnuTLS encoded and parsed UID fields as IA5String. This was
373 incorrect, it should have used DirectoryString. Now it will use
374 DirectoryString for the UID field, but for backwards compatibility it
375 will also accept IA5String UID's. Reported by Max Kellermann
378 ** Improve out-of-sourcedir builds from CVS.
379 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
381 ** Bootstrap tools changed.
382 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
383 building GnuTLS from CVS. Libtool 1.5.22 is used.
385 ** Fixed a syntax error in lib/gnutls.asn.
386 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
388 ** Added German translation of GnuTLS messages.
390 ** Update of gnulib files.
392 ** API and ABI modifications:
393 No changes since last version.
395 * Version 1.7.0 (released 2006-11-29)
397 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
398 The details is that the protocol priority set by
399 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
400 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
402 ** Preliminary support for TLS 1.2.
403 The client has been successfully tested against
404 https://www.mikestoolbox.org:4433/.
406 ** Anonself test now print a lot of debugging info, including TLS version.
408 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
410 ** Update of gnulib files.
412 ** API and ABI modifications:
413 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
415 *** Pulled up from stable 1.6.x branch:
417 ** Fix ./configure failure with non-GCC compilers.
418 This fixes the following error message:
419 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
420 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
422 * Version 1.6.1 (released 2006-12-28)
424 ** Fix the list of trusted CAs that server's send to clients.
425 Before, the list contained issuer DN's instead of subject DN's of the
426 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
428 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
429 Reported by Max Kellermann <max@duempel.org>.
431 ** Encode UID fields in DN's as DirectoryString.
432 Before GnuTLS encoded and parsed UID fields as IA5String. This was
433 incorrect, it should have used DirectoryString. Now it will use
434 DirectoryString for the UID field, but for backwards compatibility it
435 will also accept IA5String UID's. Reported by Max Kellermann
438 ** Fix ./configure failure with non-GCC compilers.
439 This fixes the following error message:
440 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
441 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
443 ** API and ABI modifications:
444 No changes since last version.
446 * Version 1.6.0 (released 2006-11-17)
448 ** No changes since 1.5.5.
449 The major changes compared to the 1.4.x branch are:
451 *** A GnuTLS C++ library is part of the official distribution.
452 Currently there are no examples or documentation, but hopefully this
453 will change. See gnutlsxx.h for the API.
455 *** Windows is a supported platform.
456 There are, however, two know bugs. One is related to select() in
457 command line tools (not, nota bene, in the library), the other is a
458 problem with libgcrypt that causes delays. Help is needed to resolve
459 those issues, so we feel we can't delay the release because of this.
461 *** New APIs for custom push/pull function error reporting.
462 The new APIs are gnutls_transport_set_errno and
463 gnutls_transport_set_global_errno. See the release notes for version
464 1.5.4 for more information.
466 *** Self tests are run under valgrind, if available. See --disable-valgrind.
468 * Version 1.5.5 (released 2006-11-16)
470 ** Correctly bump shared library version after adding new APIs.
471 This was forgotten in the last release.
473 ** Fix unsigned vs signed problem in ex-x509-info.c example.
474 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
476 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
478 ** Update of gnulib files.
480 ** API and ABI modifications:
481 No changes since last version.
483 * Version 1.5.4 (released 2006-11-07)
485 ** New API functions to set errno in push/pull functions.
486 Under Windows, setting the errno variable in a push/pull replacement
487 may end up setting the wrong errno variable, and GnuTLS send/recv
488 functions become confused about the real errno returned from a failed
489 push/pull function. Therefor, we have added two APIs to set the errno
490 variable used by GnuTLS. The APIs can also help to keep things
491 thread-safe, by avoiding potentially global variables. Typically,
492 instead of setting errno in your push/pull function, you will call one
493 of these functions. It is recommended to use
494 gnutls_transport_set_errno, but if you don't have the session variable
495 easily accessible in the push/pull replacement function, you can use
496 gnutls_transport_set_global_errno. Suggested by Tim Kosse
497 <tim.kosse@filezilla-project.org>.
499 void gnutls_transport_set_errno (gnutls_session_t session, int err);
500 void gnutls_transport_set_global_errno (int err);
502 ** When calling `recv' or `send' Windows errors are handled properly.
503 The Windows recv/send functions doesn't use errno, and GnuTLS now use
504 WSAGetLastError to access the error condition instead.
506 ** Several OpenPGP API fixes.
507 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
508 important fix is to change the return value of
509 gnutls_openpgp_privkey_get_pk_algorithm and
510 gnutls_openpgp_key_get_pk_algorithm from 'int' to
511 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
512 compatible with 'int').
514 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
515 ** version, try to negotiate the highest version support by the GnuTLS server,
516 ** instead of the lowest.
517 Reported by <Pasi.Eronen@nokia.com>.
519 ** Replace old constructs with use of gnulib modules.
520 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
521 the code. If the headers doesn't exist on the target system, gnulib
522 will make sure its replacement header files are used instead.
524 ** Fix SOVERSION computation for *.def files.
525 This fixes build errors similar to "No rule to make target
526 `libgnutls-`expr', needed by `all-am'." when building for Windows.
528 ** gnutls_check-version uses strverscmp from gnulib.
530 ** Update of gnulib files.
532 ** API and ABI modifications:
533 gnutls_transport_set_errno: ADD
534 gnutls_transport_set_global_errno: ADD
536 * Version 1.5.3 (released 2006-10-26)
538 ** Add new self-test of RSA-MD5 signature chains.
539 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
540 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
541 and is based on the work by Marc Stevens et al, see
542 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
544 ** Re-factor self tests.
546 ** The include copy of Libtasn1 is updated to version 0.3.7.
548 ** The included copy of OpenCDK is updated to version 0.5.11.
550 ** Fix the filename of the *.def file on Windows after library version bump.
552 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
553 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
554 gnulib modules. Earlier we could only use the LGPL'ed module from
555 gnulib, because two gnulib directories in the same project didn't
558 ** API and ABI modifications:
559 No changes since last version.
561 * Version 1.5.2 (released 2006-10-03)
563 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
564 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
565 shared library version than this version, so you'll have to remove
566 them and possibly relink your applications. The reason for this is
567 that no API/ABI changes have been made since the 1.4.x branch, and
568 that incrementing the shared library version was a mistake. Reported
569 by Andreas Metzler <ametzler@downhill.at.eu.org>.
571 ** Fix off-by-one error when computing length to malloc.
572 The code is used by gnutls_openpgp_add_keyring_file and
573 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
574 <agl@imperialviolet.org>.
576 ** Add version script for the GnuTLS C++ library.
577 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
579 ** Fix the C++ compiler detection logic.
580 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
582 ** Update of gnulib files.
584 ** API and ABI modifications:
585 No changes since last version.
587 * Version 1.5.1 (released 2006-09-21)
589 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
590 ** Crypto 06 rump session attack.
591 In particular, we check that the digestAlgorithm.parameters field is
592 missing or empty, to avoid that it can contain "garbage" that may be
593 used to alter the numeric properties of the signature. See
594 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
595 not exactly the same as the problem we fix here). Reported by Yutaka
596 OIWA <y.oiwa@aist.go.jp>.
598 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
599 up to date information.
601 ** Add self test to test for above flaw.
603 ** Fix gnutls-cli-debug regarding resume support detection.
604 Earlier, if the session-id from the server had a length of 0, it would
605 indicate the the server supports resumption, which isn't the case.
606 Reported by Kataja Kai <kai.kataja@op.fi>.
608 ** Fix building of examples on FreeBSD by including netinet/in.h.
609 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
611 ** Fix certtool bug that caused the private key to not be loaded when
612 generating a certificate with --load-request, which in turn triggered
613 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
614 by Sascha Ziemann <sascha.ziemann@secunet.com>.
616 ** gnutls-cli and gnutls-serv works on Windows.
617 The problem was the select() call that doesn't work on file
618 descriptors (stdin) on Windows. We borrowed some code from plibc to
619 solve this. It appears to be somewhat unreliable though.
621 ** Autoconf 2.60 is now used.
623 ** API and ABI modifications:
624 No changes since last version.
626 * Version 1.5.0 (released 2006-08-13)
628 ** Change SRP and Cert-Type extensions to match IANA registry.
630 ** Fixed bug in OpenPGP authentication handshake.
632 ** Improvements for building under MinGW.
633 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
634 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
635 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
636 at run-time from ws2_32.dll, and falls back on a simple replacement if
637 it is not available. Builds the library with -mms-bitfields
638 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
639 create *.def files, which are installed.
641 ** The examples now (conditionally) include config.h and link to gnulib.
642 No other source changes were necessary, so the examples should
643 continue to be possible to use stand-alone without any autoconf or
646 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
647 You may unconditionally disable it with --disable-cxx. See
648 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
651 ** Made command line tool '--version' behave according to GNU Standards.
652 This enables 'make distcheck' to succeed.
654 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
656 ** Make --without-included-libtasn1 work.
657 Reported by Daniel Black <dragonheart@gentoo.org>.
659 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
660 See http://www.gnu.org/software/gnutls/security.html regardging

662 satyakumar <satyam_kkd@hyd.hellosoft.com>.
664 ** API and ABI modifications:
665 No changes since last version.
667 * Version 1.4.5 (released 2006-11-06)
669 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
670 ** version, try to negotiate the highest version support by the GnuTLS server,
671 ** instead of the lowest.
672 Reported by <Pasi.Eronen@nokia.com>.
674 ** Fix typo in doc/examples/ex-serv-pgp.c.
675 Reported by Adam Langley" <agl@imperialviolet.org>.
677 ** API and ABI modifications:
678 No changes since last version.
680 * Version 1.4.4 (released 2006-09-12)
682 ** Relax the test that caught signatures that exploit the variant of
683 ** Bleichenbacher's Crypto 06 rump session attack on our
684 ** verification logic flaw.
685 In particular, we now permit the digestAlgorithm.parameters field to
686 be present but empty, whereas in 1.4.3 we actually checked that the
689 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
690 The messages are only printed in debug mode, which is not recommended
691 for normal use, and thus logging this situation cannot be abused as an
692 oracle in typical recommended situations.
694 ** API and ABI modifications:
695 No changes since last version.
697 * Version 1.4.3 (released 2006-09-08)
699 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
700 ** Crypto 06 rump session attack.
701 In particular, we check that the digestAlgorithm.parameters field is
702 empty, to avoid that it can contain "garbage" that may be used to
703 alter the numeric properties of the signature. See

718 ** Fix crash in gnutls_x509_crt_sign2 if passed a NULL issuer_key.
720 ** API and ABI modifications:
721 No changes since last version.
723 * Version 1.4.2 (released 2006-08-12)
725 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
726 This can happen if you call gnutls_certificate_verify_peers2 and have
727 a certain mix of local CA certificates and the peer send special
728 certificates, that together trigger certain behaviour. It is not
729 known at this point whether the crash can be triggered without the
730 special local CA certificate, and thus turn this into a remote crash
731 of clients that verify server certificates when they talk to a server
732 with the special server certificate. See GNUTLS-SA-2006-2 on
733 http://www.gnu.org/software/gnutls/security.html for more up to date
734 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
736 ** Change SRP and Cert-Type extensions to match IANA registry.
738 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
740 ** Make --without-included-libtasn1 work.
741 Reported by Daniel Black <dragonheart@gentoo.org>.
743 ** API and ABI modifications:
744 No changes since last version.
746 * Version 1.4.1 (released 2006-06-14)
748 ** Replaced inactive ifdefs to enable openpgp support in test programs.
750 ** Fixed bug in OpenPGP authentication handshake.
752 ** Fixed typographical in man pages.
754 ** Build fixes of the manual.
756 ** Added Swedish translation.
758 ** API and ABI modifications:
759 No changes since last version.
761 * Version 1.4.0 (released 2006-05-15)
763 ** Remove GnuTLS 0.8.x compatibility functions.
765 ** The libgcrypt RNG is initialized in gnutls_global_init().
767 ** TLS/IA API changes from Emile van Bergen.
768 A dummy credential structure is not needed now, if you wish to use the
769 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
772 ** The self-tests are now run under valgrind, if it is installed.
774 ** Libtasn1 is updated to 0.3.4, and that version is now required.
776 ** The command line tools now use getaddrinfo and support IPv6.
778 ** API and ABI modifications:
779 _gnutls_x509_get_raw_crt_activation_time,
780 _gnutls_x509_get_raw_crt_expiration_time: Removed.
781 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
782 gnutls_ia_enable: Added.
784 * Version 1.3.5 (released 2006-03-08)
786 ** Error messages are now translated using GNU Gettext.
788 ** The function gnutls_x509_crt_to_xml now return an internal error.
789 This means that the code to convert X.509 certificates to XML format
790 does not work any more. The reason is that the function called
791 libtasn1 internal functions. It seems unclean for libtasn1 to export
792 the APIs needed here. Instead it would be better to implement XML
793 support inside libtasn1 properly. If you need this functionality
794 strongly, please consider looking into implementing this suggested
795 approach instead. As a workaround, you may also modify lib/x509/xml.c
796 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
798 ** Libraries are now built with libtool's -no-undefined.
799 This helps producing libraries for Windows using mingw32.
801 ** Doc fixes to explain that gnutls_record_send can block.
803 ** Libtasn1 0.3.1 or later is now required.
804 The include copy has been updated too.
806 ** gnutls-cli can now recognize services and port numbers with the -p option.
808 ** API and ABI modifications:
809 No changes since last version.
811 * Version 1.3.4 (released 2006-02-09)
813 ** Fix read of out bounds bug in DER parser.
814 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
815 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
816 previous bug fix. The included libtasn1 version in GnuTLS has been
819 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
820 longer invalidate a session if the underlying send fails, but it will
821 prevent future writes. That is to allow reading the already received data.
822 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
824 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
825 gnutls_certificate_set_x509_trust(), that caused memory corruption if
826 more than one certificates were added. Report and patch by Max Kellermann.
828 ** Fix build problems of OpenCDK on AIX.
829 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
831 ** API and ABI modifications:
832 No changes since last version.
834 * Version 1.3.3 (released 2006-01-12)
836 ** New API to access the TLS master secret.
837 When possible, you should use the TLS PRF functions instead.
838 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
840 ** Improved handling when multiple libraries use GnuTLS at the same time.
841 Now gnutls_global_init() can be called multiple times, and
842 gnutls_global_deinit() will only deallocate the structure when it has
843 been called as many times as gnutls_global_init() was called.
845 ** Added a self test of TLS resume functionality.
847 ** Fix crash in TLS resume code, caused by TLS/IA changes.
849 ** Documentation fixes about thread unsafety, prompted by
850 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
851 In particular, gnutls_global_init() and gnutls_global_deinit() are not
852 thread safe. Careful callers may want to protect the call using a
853 mutex. The problem could also be ignored, which would cause a memory
854 leak under rare conditions when two threads invoke the function
855 roughly at the same time.
857 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
859 ** The code was indented again, including the external header files.
861 ** API and ABI modifications:
862 New functions to retrieve the master secret value:
863 gnutls_session_get_master_secret
865 Add a 'const' keyword to existing API:
866 gnutls_x509_crq_get_challenge_password
868 * Version 1.3.2 (released 2005-12-15)
870 ** GnuTLS now support TLS Inner application (TLS/IA).
871 This is per draft-funk-tls-inner-application-extension-01. This
872 functionality is added to libgnutls-extra, so it is licensed under the
873 GNU General Public License.
875 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
876 The PRF is used by some protocols building on TLS, such as EAP-PEAP
877 and EAP-TTLS. One function to access the raw PRF and one to access
878 the PRF seeded with the client/server random fields are provided.
879 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
881 ** New APIs to acceess the client and server random fields in a session.
882 These fields can be useful by protocols using TLS. Note that these
883 fields are typically used as input to the TLS PRF, and if this is your
884 intended use, you should use the TLS PRF API that use the
885 client/server random field directly. Suggested by Jouni Malinen
886 <jkmaline@cc.hut.fi>.
888 ** Internal type cleanups.
889 The uint8, uint16, uint32 types have been replaced by uint8_t,
890 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
891 correct types on platforms that lack them. The uint type have been
892 replaced by unsigned.
894 ** API and ABI modifications:
895 New functions to invoke the TLS Pseudo-Random-Function (PRF):
899 New functions to retrieve the session's client and server random values:
900 gnutls_session_get_server_random
901 gnutls_session_get_client_random
903 New function, to perform TLS/IA handshake:
906 New function to decide whether to do a TLS/IA handshake:
907 gnutls_ia_handshake_p
909 New functions to allocate a TLS/IA credential:
910 gnutls_ia_allocate_client_credentials
911 gnutls_ia_free_client_credentials
912 gnutls_ia_allocate_server_credentials
913 gnutls_ia_free_server_credentials
915 New functions to handle the AVP callback:
916 gnutls_ia_set_client_avp_function
917 gnutls_ia_set_client_avp_ptr
918 gnutls_ia_get_client_avp_ptr
919 gnutls_ia_set_server_avp_function
920 gnutls_ia_set_server_avp_ptr
921 gnutls_ia_get_server_avp_ptr
923 New functions, to toggle TLS/IA application phases:
924 gnutls_ia_require_inner_phase
926 New function to mix session keys with inner secret:
927 gnutls_ia_permute_inner_secret
929 Low-level API (used internally by gnutls_ia_handshake):
930 gnutls_ia_endphase_send
934 New functions that can be used after successful TLS/IA negotiation:
935 gnutls_ia_generate_challenge
936 gnutls_ia_extract_inner_secret
938 Enum type with TLS/IA modes:
941 Enum type with TLS/IA packet types:
944 Enum values for TLS/IA alerts:
945 GNUTLS_A_INNER_APPLICATION_FAILURE
946 GNUTLS_A_INNER_APPLICATION_VERIFICATION
948 New error codes, to signal when an application phase has finished:
949 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
950 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
952 New error code to signal TLS/IA verify failure:
953 GNUTLS_E_IA_VERIFY_FAILED
955 * Version 1.3.1 (released 2005-12-08)
957 ** Support for DHE-PSK cipher suites has been added.
958 This method offers perfect forward secrecy.
960 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
961 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
963 ** Corrected a bug in certtool for 64 bit machines. Reported
964 by Max Kellermann <max@duempel.org>.
966 ** New function to set a X.509 private key and certificate pairs, and/or
967 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
970 The integrity of the PKCS#12 file is protected through a password
971 based MAC; public-key based signatures for integrity protection are
972 not supported. PKCS#12 bags may be encrypted using password derived
973 symmetric keys, public-key based encryption is not supported. The
974 PKCS#8 keys may be encrypted using passwords. The API use the same
975 password for all operations. We believe that any more flexibility
976 create too much complexity that would hurt overall security, but may
977 add more PKCS#12 related APIs if real-world experience indicate
980 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
981 reported by Emile van Bergen <emile@e-advies.nl>.
982 This will enable "certtool -k -8" to parse those keys.
984 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
985 Use "certtool -p -8" and press press enter at the prompt. Earlier,
986 certtool would have encrypted the key using an empty password.
988 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
989 Earlier it would have prompted the user for it, even if --password was
992 ** Added self test of PKCS#8 parsing.
993 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
994 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
997 ** API and ABI modifications:
998 New function to set X.509 credentials from a PKCS#12 file:
999 gnutls_certificate_set_x509_simple_pkcs12_file
1001 New gnutls_kx_algorithm_t enum type:
1004 New API to return session data (basically same as gnutls_session_get_data):
1005 gnutls_session_get_data2
1007 New API to set PSK Diffie-Hellman parameters:
1008 gnutls_psk_set_server_dh_params
1010 * Version 1.3.0 (2005-11-15)
1012 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
1013 This add several new APIs, see below. Read the updated manual for
1014 more information. A new self test "pskself" has been added, that will
1015 test this functionality.
1017 ** The session resumption data are now system independent.
1019 ** The code has been re-indented to conform to the GNU coding style.
1021 ** Removed the RIPEMD ciphersuites.
1023 ** Added a discussion of the internals of gnutls in manual.
1025 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
1027 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
1029 ** Make sure config.h is included first in a few files, from Albert Chin.
1031 ** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
1033 ** Don't install SRP programs and man pages if --disable-srp-authentication,

1074 gnutls_srp_base64_decode
1076 * Version 1.2.11 (2006-05-11)
1077 - The function gnutls_x509_crt_to_xml is not supported any more, and
1078 return an internal error. The reason is that the function called
1079 internal libtasn1 functions which are no longer exported from
1081 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
1082 - Updated gnulib compatibility files.
1083 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
1084 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
1085 - API and ABI modifications:
1086 No changes since last version.
1088 * Version 1.2.10 (2006-02-09)
1089 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
1090 <admin@gleg.net>, and debugging help from Protover SSL.
1091 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
1092 The included version has been updated too.
1093 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to

1103 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
1105 * Version 1.2.9 (2005-11-07)
1106 - Documentation was updated and improved.
1107 - RSA-MD2 is now supported for verifying digital signatures.
1108 - Due to cryptographic advances, verifying untrusted X.509
1109 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
1110 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
1111 applications that must remain interoperable, you can use the
1112 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
1113 flags when verifying certificates. Naturally, this is not
1114 recommended default behaviour for applications. To enable the
1115 broken algorithms, call gnutls_certificate_set_verify_flags with the
1116 proper flag, to change the verification mode used by
1117 gnutls_certificate_verify_peers2.
1118 - Make it possible to send empty data through gnutls_record_send,
1119 to align with the send(2) API.
1120 - Some changes in the certificate receiving part of handshake to prevent
1121 some possible errors with non-blocking servers.
1122 - Added numeric version symbols to permit simple CPP-based feature
1123 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
1124 - The (experimental) low-level crypto alternative to libgcrypt used
1125 earlier (Nettle) has been replaced with crypto code from gnulib.
1126 This leads to easier re-use of these components in other projects,
1127 leading to more review and simpler maintenance. The new configure
1128 parameter --with-builtin-crypto replace the old --with-nettle, and
1129 must be used if you wish to enable this functionality. See README
1130 under "Experimental" for more information. Internally, GnuTLS has
1131 been updated to use the new "Generic Crypto" API in gl/gc.h. The
1132 API is similar to the old crypto/gc.h, because the gnulib code were
1133 based on GnuTLS's gc.h.
1134 - Fix compiler warning in the "anonself" self test.
1135 - API and ABI modifications:
1136 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
1137 This doesn't reflect a change in behaviour,
1138 so we don't break backwards compatibility.
1139 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
1140 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
1141 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
1142 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
1144 gnutls_x509_crt_list_verify,
1145 gnutls_x509_crt_verify, or
1146 gnutls_certificate_set_verify_flags.
1147 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
1148 used when broken signature algorithms
1149 is used (currently RSA-MD2/MD5).
1150 LIBGNUTLS_VERSION_MAJOR,
1151 LIBGNUTLS_VERSION_MINOR,
1152 LIBGNUTLS_VERSION_PATCH,
1153 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
1154 version number, can be used for feature existence
1157 * Version 1.2.8 (2005-10-07)
1158 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
1159 - Don't install the auxilliary libexamples library used by the
1160 examples in doc/examples/ on "make install", report and tiny patch
1161 from Thomas Klausner <tk@giga.or.at>.
1162 - If you pass a X.509 CA or PGP trust database to the command line
1163 tool, it will now abort the connection if the server certificate
1164 validation fails. Use the parameter --insecure to continue even
1165 after certificate validation failures. Inspired from discussion
1166 with Alexander Kotelnikov <sacha@myxomop.com>.
1167 - The test for socklen_t has been moved to gnulib.

1186 X.509 serial numbers.
1187 - Fixed build problems in getpass on uClibc and Mingw32 platforms.
1188 - Fixed compile warning regarding socklen_t on Mingw32, reported by
1189 Martin Lambers <marlam@marlam.de>.

1270 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
1271 - Added the option --get-dh-params to certtool, in order to get the
1272 parameters included in the library primes and generators.
