4 See the end for copying conditions.
6 * Version 1.7.8 (released 2007-04-16)
8 ** Added examples for the authorization extension.
9 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
11 ** The examples only use gnutls_set_default_priority().
12 The exception is when DH_ANON is needed.
14 ** Improve gnutls_set_default_priority() priorities.
15 The new approach is for it to try and negotiate all secure and
16 standard mechanisms available. Currently, DH_ANON ciphersuites and
17 LZO compressions are not enabled by default, because they are,
18 respectively, insecure and non-standardized. Note that TLS 1.2 will
19 not be enabled by default in non-experimental release until it has
20 been approved by the IETF.
22 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
23 This means that to get DH_ANON and LZO compression, you'll need to
24 specify that manually using '--kx anon' or '--comp lzo'.
26 ** Minor fixes to the human display format of X.509 certificates.
28 ** New APIs to extract Distinguished Name's from X.509 certificates.
29 Based on patch from Howard Chu <hyc@symas.com>.
31 ** Improved library searching for opencdk.
32 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
33 The deprecated opencdk.m4 is no longer used.
35 ** New APIs to list supported algorithms in the library.
36 The APIs are gnutls_cipher_list, gnutls_mac_list,
37 gnutls_compression_list, gnutls_protocol_list,
38 gnutls_certificate_type_list, gnutls_kx_list, and
39 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
41 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
43 ** New configure option --disable-tls-authorization to disable tls-authz.
45 ** Fix prototype for `gnutls_psk_set_client_credentials'.
46 The last parameter was renamed from 'flags' to 'format' and the type
47 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
48 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
51 ** API and ABI modifications:
52 gnutls_x509_dn_t: ADD.
53 gnutls_x509_ava_st: ADD.
54 gnutls_x509_crt_get_subject,
55 gnutls_x509_crt_get_issuer: ADD.
56 gnutls_x509_dn_get_rdn_ava: ADD.
57 gnutls_cipher_list: ADD.
59 gnutls_compression_list: ADD.
60 gnutls_protocol_list: ADD.
61 gnutls_certificate_type_list: ADD.
63 gnutls_cipher_suite_info: ADD.
65 * Version 1.7.7 (released 2007-02-22)
67 ** Support for supplemental handshake messages and authorization data.
68 Supplemental data is described in RFC 4680 and the authorization
69 extensions in draft-housley-tls-authz-extns-07.
71 ** Support for authorization data in gnutls-cli and gnutls-serv.
72 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
74 ** Fix for gnutls_x509_crt_check_hostname.
75 Before it would have reported that the certificate matched a hostname
76 when it did not have any dNSName or any CN field. Report and tiny
77 patch from "Richard W.M. Jones" <rjones@redhat.com>.
79 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
80 Tests regressions of the bug, and several other features.
82 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
83 Before there were no support for iPAddress SAN's during comparison.
85 ** New API to print information about CRL's.
86 The function is gnutls_x509_crl_print.
88 ** New API to extract signature value from CRL's.
89 The function is gnutls_x509_crl_get_signature.
91 ** Support for directoryName Subject Alternative Name's.
92 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
93 string in the provided buffer.
95 ** Internal improvements to certtool.
96 It uses gnutls_x509_crl_print to print CRL information. It uses some
97 more gnulib modules to simplify error handling.
99 ** API and ABI modifications:
100 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
101 gnutls_supplemental_data_format_type_t: ADD.
102 gnutls_authz_data_format_type_t: ADD.
103 gnutls_supplemental_get_name: ADD.
104 gnutls_authz_recv_callback_func,
105 gnutls_authz_send_callback_func: ADD, callback prototypes.
106 gnutls_authz_enable: ADD.
107 gnutls_authz_send_x509_attr_cert,
108 gnutls_authz_send_saml_assertion,
109 gnutls_authz_send_x509_attr_cert_url,
110 gnutls_authz_send_saml_assertion_url: ADD.
111 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
112 gnutls_x509_crl_print: ADD.
113 gnutls_x509_crl_get_signature: ADD.
115 * Version 1.7.6 (released 2007-02-12)
117 ** Support for 'otherName' Subject Alternative Names.
118 The existing API gnutls_x509_crt_get_subject_alt_name may now return
119 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
120 To find out the otherName OID (necessary for proper parsing of the
121 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
122 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
123 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
124 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
126 ** Certtool can print otherName SAN values for certificates.
127 For known otherName OIDs (currently only id-on-xmppAddr as defined by
128 RFC 3920), it will also print the name.
130 ** Fix TLS 1.2 RSA signing in servers.
131 Before it used the old-style MD5+SHA1 signature, but the TLS
132 signatures should be normal PKCS#1 signatures. FYI, we use and
133 require that DigestInfo parameters are present and NULL for TLS 1.2.
135 ** Add APIs to access X.509 extensions sequentially.
136 The existing APIs gnutls_x509_crt_get_extension_oid() and
137 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
138 inspect the extensions in the order defined by the certificate.
140 ** Add API to extract signature value from X.509 certificates.
141 The function is gnutls_x509_crt_get_signature.
143 ** Fix crash when generating proxy certificates in batch mode.
144 If you don't specify a proxy policy in batch mode, it will use
147 ** Add API to print information about X.509 certificates.
148 The function is gnutls_x509_crt_print.
150 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
151 One consequence of this is that the output syntax has changed
152 slightly. Some more fields are printed.
156 ** API and ABI modifications:
157 gnutls_x509_crt_print: ADD
158 gnutls_certificate_print_formats_t: ADD, new enum.
159 gnutls_x509_crt_get_signature: ADD.
160 gnutls_x509_crt_get_extension_data: ADD.
161 gnutls_x509_crt_get_extension_info: ADD.
162 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
163 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
164 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
166 * Version 1.7.5 (released 2007-02-06)
168 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
171 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
173 ** Fix --list output for gnutls-cli and gnutls-serv.
174 Mention TLS1.2, SHA512 etc.
176 ** Manual contains new section on setting up a test HTTP server.
177 A server set up following those descriptions are available online via
178 <http://www.gnutls.org/server.html>.
180 ** Update of gnulib files.
182 ** API and ABI modifications:
183 No changes since last version.
185 * Version 1.7.4 (released 2007-02-05)
187 ** Support for RSA signing using SHA-256/384/512.
188 A new self test "sha2" tries to build a long X.509 certificate chain
189 testing all new hashes.
191 ** The gnutls-serv tool now use static DH parameters if none are supplied.
193 ** Discuss proxy certificates in the manual.
195 ** Improve bibliographical citations in the manual.
197 ** Update of gnulib files.
199 ** Fix certtool template handling of pathLenConstraints.
200 It now defaults to -1 instead of 0, which causes the field to be
201 missing unless the template specify it.
203 ** API and ABI modifications:
206 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
209 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
210 GNUTLS_SIGN_RSA_SHA256,
211 GNUTLS_SIGN_RSA_SHA384,
212 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
214 * Version 1.7.3 (released 2007-02-01)
216 ** New option to certtool: --generate-proxy.
217 This will generate a Proxy Certificate from an end entity certificate.
218 Proxy Certificates are documented in RFC 3820. You will need to
219 specify the proxy certificate's private key with --load-privkey, the
220 user certificate with --load-certificate and the private key used to
221 sign the new proxy certificate with --load-ca-privkey. Certtool will
222 query for proxy path length and the policy language OID. Currently
223 only OIDs that have an empty policy are supported (which includes the
224 two OIDs defined by RFC 3820).
226 ** Certtool --certificate-info now prints information for Proxy Certificates.
227 Before the proxy extension was just printed as DER encoded data.
229 ** New APIs to set proxy subject names and get/set proxy cert extension.
231 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
233 ** Added self-test to test for regressions of pathLenConstraint bug.
234 Incidentally, this also test (some) other regressions or changes in
235 the output from certtool --certificate-info.
237 ** When certtool generates CA certificates, pressing enter on the path
238 ** length constraint query will now remove the field.
239 Before it set the path length constraint to 0, which is a rather poor
242 ** Certtool now print times in UTC when printing certificate/CRL info.
244 ** Add better fix to work around C++ compiler bug on Mac OS X.
245 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
247 ** Fix import of ASCII armored OpenPGP keys.
248 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
250 ** Update of gnulib files.
252 ** API and ABI modifications:
253 gnutls_x509_crt_set_proxy_dn: ADD.
254 gnutls_x509_crt_set_proxy: ADD.
255 gnutls_x509_crt_get_proxy: ADD.
257 * Version 1.7.2 (released 2007-01-14)
259 ** Certtool now print the value of the pathLenConstraints field for certs.
261 ** Certtool now query for path length constraints when generating CA certs.
262 For batch uses, the certtool configuration name is "path_len".
263 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
265 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
266 The new functions gnutls_x509_crt_get_basic_constraints and
267 gnutls_x509_crt_set_basic_constraints provide a superset of the
268 functionality in the old gnutls_x509_crt_get_ca_status and
269 gnutls_x509_crt_set_ca_status (respectively), but the old functions
270 will continue to be supported.
272 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
273 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
274 OpenCDK release with this patch will be made soon, which should bump
275 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
277 ** Certtool --to-p12 can now store more than one certificate in the blob.
278 Before it could only store one certificate, but now it will read and
279 store as many certificate there are from the --load-certificate file.
280 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
282 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
283 In particular, the OpenPGP function variables are no longer part of
284 the exported libgnutls interface, and no header files from
285 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
286 were never intended for non-internal purposes, and thus this does not
287 imply a change in the external API/ABI.
289 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
290 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
292 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
293 Before these parameters were set to make GnuTLS build under mingw32,
294 however, they appear to no longer be necessary.
296 ** A minor fix to the C++ library to make it build.
297 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
299 ** Update of gnulib files.
301 ** API and ABI modifications:
302 gnutls_x509_crt_get_basic_constraints: ADD.
303 gnutls_x509_crt_set_basic_constraints: ADD.
304 cdk_pubkey_to_sexp: ADD (in opencdk).
305 cdk_seckey_to_sexp: ADD (in opencdk).
307 * Version 1.7.1 (released 2006-12-28)
309 ** TLS 1.2 server side fix.
310 The Certificate Request sent did not contain the list of supported
311 hashes field, thus violating the protocol. It will now contain an
312 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
314 ** TLS 1.2 DSA signature verification fix.
315 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
317 ** Fix the list of trusted CAs that server's send to clients.
318 Before, the list contained issuer DN's instead of subject DN's of the
319 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
321 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
322 Also added a self-test in tests/certificate_set_x509_crl.c to test the
323 function. Reported by Max Kellermann <max@duempel.org>.
325 ** Encode UID fields in DN's as DirectoryString.
326 Before GnuTLS encoded and parsed UID fields as IA5String. This was
327 incorrect, it should have used DirectoryString. Now it will use
328 DirectoryString for the UID field, but for backwards compatibility it
329 will also accept IA5String UID's. Reported by Max Kellermann
332 ** Improve out-of-sourcedir builds from CVS.
333 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
335 ** Bootstrap tools changed.
336 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
337 building GnuTLS from CVS. Libtool 1.5.22 is used.
339 ** Fixed a syntax error in lib/gnutls.asn.
340 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
342 ** Added German translation of GnuTLS messages.
344 ** Update of gnulib files.
346 ** API and ABI modifications:
347 No changes since last version.
349 * Version 1.7.0 (released 2006-11-29)
351 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
352 The details is that the protocol priority set by
353 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
354 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
356 ** Preliminary support for TLS 1.2.
357 The client has been successfully tested against
358 https://www.mikestoolbox.org:4433/.
360 ** Anonself test now print a lot of debugging info, including TLS version.
362 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
364 ** Update of gnulib files.
366 ** API and ABI modifications:
367 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
369 *** Pulled up from stable 1.6.x branch:
371 ** Fix ./configure failure with non-GCC compilers.
372 This fixes the following error message:
373 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
374 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
376 * Version 1.6.1 (released 2006-12-28)
378 ** Fix the list of trusted CAs that server's send to clients.
379 Before, the list contained issuer DN's instead of subject DN's of the
380 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
382 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
383 Reported by Max Kellermann <max@duempel.org>.
385 ** Encode UID fields in DN's as DirectoryString.
386 Before GnuTLS encoded and parsed UID fields as IA5String. This was
387 incorrect, it should have used DirectoryString. Now it will use
388 DirectoryString for the UID field, but for backwards compatibility it
389 will also accept IA5String UID's. Reported by Max Kellermann
392 ** Fix ./configure failure with non-GCC compilers.
393 This fixes the following error message:
394 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
395 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
397 ** API and ABI modifications:
398 No changes since last version.
400 * Version 1.6.0 (released 2006-11-17)
402 ** No changes since 1.5.5.
403 The major changes compared to the 1.4.x branch are:
405 *** A GnuTLS C++ library is part of the official distribution.
406 Currently there are no examples or documentation, but hopefully this
407 will change. See gnutlsxx.h for the API.
409 *** Windows is a supported platform.
410 There are, however, two know bugs. One is related to select() in
411 command line tools (not, nota bene, in the library), the other is a
412 problem with libgcrypt that causes delays. Help is needed to resolve
413 those issues, so we feel we can't delay the release because of this.
415 *** New APIs for custom push/pull function error reporting.
416 The new APIs are gnutls_transport_set_errno and
417 gnutls_transport_set_global_errno. See the release notes for version
418 1.5.4 for more information.
420 *** Self tests are run under valgrind, if available. See --disable-valgrind.
422 * Version 1.5.5 (released 2006-11-16)
424 ** Correctly bump shared library version after adding new APIs.
425 This was forgotten in the last release.
427 ** Fix unsigned vs signed problem in ex-x509-info.c example.
428 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
430 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
432 ** Update of gnulib files.
434 ** API and ABI modifications:
435 No changes since last version.
437 * Version 1.5.4 (released 2006-11-07)
439 ** New API functions to set errno in push/pull functions.
440 Under Windows, setting the errno variable in a push/pull replacement
441 may end up setting the wrong errno variable, and GnuTLS send/recv
442 functions become confused about the real errno returned from a failed
443 push/pull function. Therefor, we have added two APIs to set the errno
444 variable used by GnuTLS. The APIs can also help to keep things
445 thread-safe, by avoiding potentially global variables. Typically,
446 instead of setting errno in your push/pull function, you will call one
447 of these functions. It is recommended to use
448 gnutls_transport_set_errno, but if you don't have the session variable
449 easily accessible in the push/pull replacement function, you can use
450 gnutls_transport_set_global_errno. Suggested by Tim Kosse
451 <tim.kosse@filezilla-project.org>.
453 void gnutls_transport_set_errno (gnutls_session_t session, int err);
454 void gnutls_transport_set_global_errno (int err);
456 ** When calling `recv' or `send' Windows errors are handled properly.
457 The Windows recv/send functions doesn't use errno, and GnuTLS now use
458 WSAGetLastError to access the error condition instead.
460 ** Several OpenPGP API fixes.
461 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
462 important fix is to change the return value of
463 gnutls_openpgp_privkey_get_pk_algorithm and
464 gnutls_openpgp_key_get_pk_algorithm from 'int' to
465 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
466 compatible with 'int').
468 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
469 ** version, try to negotiate the highest version support by the GnuTLS server,
470 ** instead of the lowest.
471 Reported by <Pasi.Eronen@nokia.com>.
473 ** Replace old constructs with use of gnulib modules.
474 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
475 the code. If the headers doesn't exist on the target system, gnulib
476 will make sure its replacement header files are used instead.
478 ** Fix SOVERSION computation for *.def files.
479 This fixes build errors similar to "No rule to make target
480 `libgnutls-`expr', needed by `all-am'." when building for Windows.
482 ** gnutls_check-version uses strverscmp from gnulib.
484 ** Update of gnulib files.
486 ** API and ABI modifications:
487 gnutls_transport_set_errno: ADD
488 gnutls_transport_set_global_errno: ADD
490 * Version 1.5.3 (released 2006-10-26)
492 ** Add new self-test of RSA-MD5 signature chains.
493 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
494 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
495 and is based on the work by Marc Stevens et al, see
496 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
498 ** Re-factor self tests.
500 ** The include copy of Libtasn1 is updated to version 0.3.7.
502 ** The included copy of OpenCDK is updated to version 0.5.11.
504 ** Fix the filename of the *.def file on Windows after library version bump.
506 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
507 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
508 gnulib modules. Earlier we could only use the LGPL'ed module from
509 gnulib, because two gnulib directories in the same project didn't
512 ** API and ABI modifications:
513 No changes since last version.
515 * Version 1.5.2 (released 2006-10-03)
517 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
518 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
519 shared library version than this version, so you'll have to remove
520 them and possibly relink your applications. The reason for this is
521 that no API/ABI changes have been made since the 1.4.x branch, and
522 that incrementing the shared library version was a mistake. Reported
523 by Andreas Metzler <ametzler@downhill.at.eu.org>.
525 ** Fix off-by-one error when computing length to malloc.
526 The code is used by gnutls_openpgp_add_keyring_file and
527 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
528 <agl@imperialviolet.org>.
530 ** Add version script for the GnuTLS C++ library.
531 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
533 ** Fix the C++ compiler detection logic.
534 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
536 ** Update of gnulib files.
538 ** API and ABI modifications:
539 No changes since last version.
541 * Version 1.5.1 (released 2006-09-21)
543 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
544 ** Crypto 06 rump session attack.
545 In particular, we check that the digestAlgorithm.parameters field is
546 missing or empty, to avoid that it can contain "garbage" that may be
547 used to alter the numeric properties of the signature. See
548 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
549 not exactly the same as the problem we fix here). Reported by Yutaka

552 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
553 up to date information.
555 ** Add self test to test for above flaw.
557 ** Fix gnutls-cli-debug regarding resume support detection.
558 Earlier, if the session-id from the server had a length of 0, it would
559 indicate the the server supports resumption, which isn't the case.
560 Reported by Kataja Kai <kai.kataja@op.fi>.
562 ** Fix building of examples on FreeBSD by including netinet/in.h.
563 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
565 ** Fix certtool bug that caused the private key to not be loaded when
566 generating a certificate with --load-request, which in turn triggered
567 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
568 by Sascha Ziemann <sascha.ziemann@secunet.com>.
570 ** gnutls-cli and gnutls-serv works on Windows.
571 The problem was the select() call that doesn't work on file
572 descriptors (stdin) on Windows. We borrowed some code from plibc to
573 solve this. It appears to be somewhat unreliable though.
575 ** Autoconf 2.60 is now used.
577 ** API and ABI modifications:
578 No changes since last version.
580 * Version 1.5.0 (released 2006-08-13)
582 ** Change SRP and Cert-Type extensions to match IANA registry.
584 ** Fixed bug in OpenPGP authentication handshake.
586 ** Improvements for building under MinGW.
587 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
588 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
589 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
590 at run-time from ws2_32.dll, and falls back on a simple replacement if
591 it is not available. Builds the library with -mms-bitfields
592 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
593 create *.def files, which are installed.
595 ** The examples now (conditionally) include config.h and link to gnulib.
596 No other source changes were necessary, so the examples should
597 continue to be possible to use stand-alone without any autoconf or
600 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
601 You may unconditionally disable it with --disable-cxx. See
602 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the

606 This enables 'make distcheck' to succeed.
608 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
610 ** Make --without-included-libtasn1 work.
611 Reported by Daniel Black <dragonheart@gentoo.org>.

636 ** Relax the test that caught signatures that exploit the variant of
637 ** Bleichenbacher's Crypto 06 rump session attack on our
638 ** verification logic flaw.
639 In particular, we now permit the digestAlgorithm.parameters field to
640 be present but empty, whereas in 1.4.3 we actually checked that the
643 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
644 The messages are only printed in debug mode, which is not recommended
645 for normal use, and thus logging this situation cannot be abused as an
646 oracle in typical recommended situations.

677 * Version 1.4.2 (released 2006-08-12)
679 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
680 This can happen if you call gnutls_certificate_verify_peers2 and have
681 a certain mix of local CA certificates and the peer send special
682 certificates, that together trigger certain behaviour. It is not
683 known at this point whether the crash can be triggered without the
684 special local CA certificate, and thus turn this into a remote crash
685 of clients that verify server certificates when they talk to a server
686 with the special server certificate. See GNUTLS-SA-2006-2 on
687 http://www.gnu.org/software/gnutls/security.html for more up to date

700 * Version 1.4.1 (released 2006-06-14)
702 ** Replaced inactive ifdefs to enable openpgp support in test programs.
704 ** Fixed bug in OpenPGP authentication handshake.
706 ** Fixed typographical in man pages.

719 ** The libgcrypt RNG is initialized in gnutls_global_init().
721 ** TLS/IA API changes from Emile van Bergen.
722 A dummy credential structure is not needed now, if you wish to use the
723 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
726 ** The self-tests are now run under valgrind, if it is installed.
728 ** Libtasn1 is updated to 0.3.4, and that version is now required.
730 ** The command line tools now use getaddrinfo and support IPv6.
732 ** API and ABI modifications:
733 _gnutls_x509_get_raw_crt_activation_time,
734 _gnutls_x509_get_raw_crt_expiration_time: Removed.
735 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
736 gnutls_ia_enable: Added.
738 * Version 1.3.5 (released 2006-03-08)
740 ** Error messages are now translated using GNU Gettext.
742 ** The function gnutls_x509_crt_to_xml now return an internal error.
743 This means that the code to convert X.509 certificates to XML format
744 does not work any more. The reason is that the function called
745 libtasn1 internal functions. It seems unclean for libtasn1 to export
746 the APIs needed here. Instead it would be better to implement XML
747 support inside libtasn1 properly. If you need this functionality
748 strongly, please consider looking into implementing this suggested
749 approach instead. As a workaround, you may also modify lib/x509/xml.c
750 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
752 ** Libraries are now built with libtool's -no-undefined.
753 This helps producing libraries for Windows using mingw32.
755 ** Doc fixes to explain that gnutls_record_send can block.
757 ** Libtasn1 0.3.1 or later is now required.
758 The include copy has been updated too.
760 ** gnutls-cli can now recognize services and port numbers with the -p option.
762 ** API and ABI modifications:
763 No changes since last version.
765 * Version 1.3.4 (released 2006-02-09)
767 ** Fix read of out bounds bug in DER parser.
768 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
769 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
770 previous bug fix. The included libtasn1 version in GnuTLS has been
773 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
774 longer invalidate a session if the underlying send fails, but it will
775 prevent future writes. That is to allow reading the already received data.
776 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
778 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
779 gnutls_certificate_set_x509_trust(), that caused memory corruption if
780 more than one certificates were added. Report and patch by Max Kellermann.
782 ** Fix build problems of OpenCDK on AIX.
783 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
785 ** API and ABI modifications:
786 No changes since last version.
788 * Version 1.3.3 (released 2006-01-12)
790 ** New API to access the TLS master secret.
791 When possible, you should use the TLS PRF functions instead.
792 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
794 ** Improved handling when multiple libraries use GnuTLS at the same time.
795 Now gnutls_global_init() can be called multiple times, and
796 gnutls_global_deinit() will only deallocate the structure when it has
797 been called as many times as gnutls_global_init() was called.
799 ** Added a self test of TLS resume functionality.
801 ** Fix crash in TLS resume code, caused by TLS/IA changes.
803 ** Documentation fixes about thread unsafety, prompted by
804 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
805 In particular, gnutls_global_init() and gnutls_global_deinit() are not
806 thread safe. Careful callers may want to protect the call using a
807 mutex. The problem could also be ignored, which would cause a memory
808 leak under rare conditions when two threads invoke the function
809 roughly at the same time.
811 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
813 ** The code was indented again, including the external header files.
815 ** API and ABI modifications:
816 New functions to retrieve the master secret value:
817 gnutls_session_get_master_secret
819 Add a 'const' keyword to existing API:
820 gnutls_x509_crq_get_challenge_password
822 * Version 1.3.2 (released 2005-12-15)
824 ** GnuTLS now support TLS Inner application (TLS/IA).
825 This is per draft-funk-tls-inner-application-extension-01. This
826 functionality is added to libgnutls-extra, so it is licensed under the
827 GNU General Public License.
829 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
830 The PRF is used by some protocols building on TLS, such as EAP-PEAP
831 and EAP-TTLS. One function to access the raw PRF and one to access
832 the PRF seeded with the client/server random fields are provided.
833 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
835 ** New APIs to acceess the client and server random fields in a session.
836 These fields can be useful by protocols using TLS. Note that these
837 fields are typically used as input to the TLS PRF, and if this is your
838 intended use, you should use the TLS PRF API that use the
839 client/server random field directly. Suggested by Jouni Malinen
840 <jkmaline@cc.hut.fi>.
842 ** Internal type cleanups.
843 The uint8, uint16, uint32 types have been replaced by uint8_t,
844 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
845 correct types on platforms that lack them. The uint type have been
846 replaced by unsigned.
848 ** API and ABI modifications:
849 New functions to invoke the TLS Pseudo-Random-Function (PRF):
853 New functions to retrieve the session's client and server random values:
854 gnutls_session_get_server_random
855 gnutls_session_get_client_random
857 New function, to perform TLS/IA handshake:
860 New function to decide whether to do a TLS/IA handshake:

874 gnutls_ia_set_server_avp_ptr
875 gnutls_ia_get_server_avp_ptr
877 New functions, to toggle TLS/IA application phases:
878 gnutls_ia_require_inner_phase
880 New function to mix session keys with inner secret:
881 gnutls_ia_permute_inner_secret
883 Low-level API (used internally by gnutls_ia_handshake):
884 gnutls_ia_endphase_send

895 Enum type with TLS/IA packet types:
898 Enum values for TLS/IA alerts:
899 GNUTLS_A_INNER_APPLICATION_FAILURE
900 GNUTLS_A_INNER_APPLICATION_VERIFICATION
902 New error codes, to signal when an application phase has finished:
903 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
904 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
906 New error code to signal TLS/IA verify failure:
907 GNUTLS_E_IA_VERIFY_FAILED
909 * Version 1.3.1 (released 2005-12-08)
911 ** Support for DHE-PSK cipher suites has been added.
912 This method offers perfect forward secrecy.
914 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
915 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
917 ** Corrected a bug in certtool for 64 bit machines. Reported
918 by Max Kellermann <max@duempel.org>.
920 ** New function to set a X.509 private key and certificate pairs, and/or
921 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
924 The integrity of the PKCS#12 file is protected through a password
925 based MAC; public-key based signatures for integrity protection are
926 not supported. PKCS#12 bags may be encrypted using password derived
927 symmetric keys, public-key based encryption is not supported. The
928 PKCS#8 keys may be encrypted using passwords. The API use the same
929 password for all operations. We believe that any more flexibility
930 create too much complexity that would hurt overall security, but may
931 add more PKCS#12 related APIs if real-world experience indicate
934 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
935 reported by Emile van Bergen <emile@e-advies.nl>.
936 This will enable "certtool -k -8" to parse those keys.
938 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
939 Use "certtool -p -8" and press press enter at the prompt. Earlier,
940 certtool would have encrypted the key using an empty password.
942 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
943 Earlier it would have prompted the user for it, even if --password was
946 ** Added self test of PKCS#8 parsing.
947 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
948 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
951 ** API and ABI modifications:
952 New function to set X.509 credentials from a PKCS#12 file:
953 gnutls_certificate_set_x509_simple_pkcs12_file
955 New gnutls_kx_algorithm_t enum type:
958 New API to return session data (basically same as gnutls_session_get_data):
959 gnutls_session_get_data2
961 New API to set PSK Diffie-Hellman parameters:
962 gnutls_psk_set_server_dh_params
964 * Version 1.3.0 (2005-11-15)
966 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
967 This add several new APIs, see below. Read the updated manual for
968 more information. A new self test "pskself" has been added, that will
969 test this functionality.
971 ** The session resumption data are now system independent.
973 ** The code has been re-indented to conform to the GNU coding style.
975 ** Removed the RIPEMD ciphersuites.

1030 * Version 1.2.11 (2006-05-11)
1031 - The function gnutls_x509_crt_to_xml is not supported any more, and
1032 return an internal error. The reason is that the function called
1033 internal libtasn1 functions which are no longer exported from
1035 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
1036 - Updated gnulib compatibility files.
1037 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
1038 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
1039 - API and ABI modifications:
1040 No changes since last version.
1042 * Version 1.2.10 (2006-02-09)
1043 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
1044 <admin@gleg.net>, and debugging help from Protover SSL.
1045 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
1046 The included version has been updated too.
1047 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to

1057 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
1059 * Version 1.2.9 (2005-11-07)
1060 - Documentation was updated and improved.
1061 - RSA-MD2 is now supported for verifying digital signatures.
1062 - Due to cryptographic advances, verifying untrusted X.509
1063 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
1064 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
1065 applications that must remain interoperable, you can use the
1066 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
1067 flags when verifying certificates. Naturally, this is not
1068 recommended default behaviour for applications. To enable the
1069 broken algorithms, call gnutls_certificate_set_verify_flags with the
1070 proper flag, to change the verification mode used by
1071 gnutls_certificate_verify_peers2.
1072 - Make it possible to send empty data through gnutls_record_send,
1073 to align with the send(2) API.
1074 - Some changes in the certificate receiving part of handshake to prevent
1075 some possible errors with non-blocking servers.
1076 - Added numeric version symbols to permit simple CPP-based feature
1077 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
1078 - The (experimental) low-level crypto alternative to libgcrypt used
1079 earlier (Nettle) has been replaced with crypto code from gnulib.
1080 This leads to easier re-use of these components in other projects,
1081 leading to more review and simpler maintenance. The new configure
1082 parameter --with-builtin-crypto replace the old --with-nettle, and
1083 must be used if you wish to enable this functionality. See README
1084 under "Experimental" for more information. Internally, GnuTLS has
1085 been updated to use the new "Generic Crypto" API in gl/gc.h. The
1086 API is similar to the old crypto/gc.h, because the gnulib code were
1087 based on GnuTLS's gc.h.
1088 - Fix compiler warning in the "anonself" self test.
1089 - API and ABI modifications:
1090 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
1091 This doesn't reflect a change in behaviour,
