GnuTLS 2.8.4

From: Simon Josefsson
Subject: GnuTLS 2.8.4
Date: Fri, 18 Sep 2009 11:26:03 +0200
User-agent: Gnus/5.110011 (No Gnus v0.11) Emacs/23.1 (gnu/linux)

We are proud to announce a new stable GnuTLS release: Version 2.8.4.

GnuTLS is a modern C library that implements 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 GnuTLS library is distributed under the terms of the GNU Lesser
General Public License version 2.1 (or later).  The "extra" GnuTLS
library (which contains TLS/IA support, LZO compression and Libgcrypt
FIPS-mode handler), the OpenSSL compatibility library, the self tests
and the command line tools are all distributed under the GNU General
Public License version 3.0 (or later).  The manual is distributed
under the GNU Free Documentation License version 1.3 (or later).

The project page of the library is available at:

What's New

** libgnutls: Enable Camellia ciphers by default.

** libgnutls: Make OpenPGP hostname checking work again.
The patch to resolve the X.509 CN/SAN issue accidentally broken
OpenPGP hostname comparison.

** libgnutls: When printing X.509 certificates, handle XMPP SANs better.
Reported by Howard Chu <address@hidden> in

** 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
<>.  The list of mirrors can be found at

Here are the BZIP2 compressed sources (6.0MB):

Here are OpenPGP detached signatures signed using key 0xB565716F:

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-2.8.4.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: 2010-04-21]
      Key fingerprint = 0424 D4EE 81A0 E3D1 19C6  F835 EDA2 1E94 B565 716F
uid                  Simon Josefsson <address@hidden>
uid                  Simon Josefsson <address@hidden>
sub   1280R/4D5D40AE 2002-05-05 [expires: 2010-04-21]

The key is available from:

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:

The manual is available online at:

In particular the following formats are available:


For developers there is a GnuTLS API reference manual formatted using
the GTK-DOC tools:

For developers interested in improving code quality, we publish
Cyclomatic code complexity charts that help you find code that may need
review and improvements:

Also useful are code coverage charts which indicate parts of the source
code that needs to be tested better by the included self-tests:

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 includes
libgpg-error v1.7, libgcrypt v1.4.4, libtasn1 v2.3, and GnuTLS v2.8.4.

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


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 AB, a
Stockholm based privately held company, is currently funding GnuTLS
maintenance.  We are always looking for interesting development
projects.  See for more details.
