GnuTLS 2.2.2

Thu Feb 21 10:00:29 CET 2008

We are pleased to announce a new stable GnuTLS release: Version 2.2.2.

GnuTLS is a modern C library that implement the standard network
security protocol Transport Layer Security (TLS), for use by network
applications.  GnuTLS is developed for GNU/Linux, but works on many
Unix-like systems and comes with a binary installer for Windows.

The core GnuTLS library is distribute under the terms of the GNU Lesser
General Public License version 2.1 (or later).  The "extra" GnuTLS
libraries -- which contains OpenPGP and TLS/IA support, LZO compression,
the OpenSSL compatibility library -- and the self tests and command line
tools are distributed under the GNU General Public License version 3.0
(or later).  The manual is distributed under the GNU Free Documentation
License version 1.2 (or later).

The project page of the library is available at:
  http://www.gnutls.org/

What's New
==========

* Version 2.2.2 (released 2008-02-21)

** Cipher priority string handling now handle strings that starts with NULL.
Thanks to Laurence Withers <l at lwithers.me.uk>.

** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
by Daniel Stenberg.

** Increased the default certificate verification chain limits and allowed
for checks without limitation.

** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
strings and return the proper size.

** API and ABI modifications:
No changes since last version.

Getting the Software
====================

GnuTLS may be downloaded from one of the mirror sites or direct from
<ftp://ftp.gnutls.org/pub/gnutls/>.  The list of mirrors can be found at
<http://www.gnu.org/software/gnutls/download.html>.  Note, that GnuPG is
not available at ftp.gnu.org.

Here are the BZIP2 compressed sources (4.8MB):

  ftp://ftp.gnutls.org/pub/gnutls/gnutls-2.2.2.tar.bz2
  http://josefsson.org/gnutls/releases/gnutls-2.2.2.tar.bz2

Here are OpenPGP detached signatures signed using key 0xB565716F:

  ftp://ftp.gnutls.org/pub/gnutls/gnutls-2.2.2.tar.bz2.sig
  http://josefsson.org/gnutls/releases/gnutls-2.2.2.tar.bz2.sig

Note, that we don't distribute gzip compressed tarballs.

In order to check that the version of GnuTLS which you are going to
install is an original and unmodified one, you should verify the OpenPGP
signature.  You can use the command

     gpg --verify gnutls-2.2.2.tar.bz2.sig

This checks whether the signature file matches the source file.  You
should see a message indicating that the signature is good and made by
that signing key.  Make sure that you have the right key, either by
checking the fingerprint of that key with other sources or by checking
that the key has been signed by a trustworthy other key.  The signing
key can be identified with the following information:

pub   1280R/B565716F 2002-05-05 [expires: 2008-06-30]
      Key fingerprint = 0424 D4EE 81A0 E3D1 19C6  F835 EDA2 1E94 B565 716F
uid                  Simon Josefsson <simon at josefsson.org>
uid                  Simon Josefsson <jas at extundo.com>
sub   1280R/4D5D40AE 2002-05-05 [expires: 2008-06-30]

The key is available from:
  http://josefsson.org/key.txt
  dns:b565716f.josefsson.org?TYPE=CERT

Alternatively, after successfully verifying the OpenPGP signature of
this announcement, you could verify that the files match the following
checksum values.  The values are for SHA-1 and SHA-224 respectively:

6b9586083c6460b0efa73959d86036ecb0a6acf8  gnutls-2.2.2.tar.bz2

Windows installer
=================

GnuTLS has been ported to the Windows operating system, and a binary
installer is available.  The installer contains DLLs for application
development, manuals, examples, and source code.  The installer consists
of libgpg-error 1.6, libgcrypt 1.4.0, libtasn1 1.3, opencdk 0.6.6, and
GnuTLS 2.2.2.

The Windows binary installer and OpenPGP signature:
  http://josefsson.org/gnutls4win/gnutls-2.2.2.exe (14MB)
  http://josefsson.org/gnutls4win/gnutls-2.2.2.exe.sig

The checksum values for SHA-1 and SHA-224 are:

0f33050ae3f0ab202474c5c8b35c39126b23ec45  gnutls-2.2.2.exe

Internationalization
====================

GnuTLS messages have been translated into Dutch, German, Malay, Polish
and Swedish.  We welcome the addition of more translations.

Support
=======

Improving GnuTLS is costly, but you can help!  We are looking for
organizations that find GnuTLS useful and wish to contribute back.  You
can contribute by reporting bugs, improve the software, or donate money
or equipment.

Commercial support contracts for GnuTLS are available, and they help
finance continued maintenance.  Simon Josefsson Datakonsult, a Stockholm
based privately held company, is currently funding GnuTLS maintenance.
We are always looking for interesting development projects.  See
http://josefsson.org/ for more details.

Happy Hacking,
Simon
