[Announce] GnuPG 1.4.9 released

Wed Mar 26 19:08:51 CET 2008
We are pleased to announce the availability of a new stable GnuPG-1
release: Version 1.4.9. This is a maintenance release to fix a possible
vulnerability introduced with 1.4.8.
The GNU Privacy Guard (GnuPG) is GNU's tool for secure communication
and data storage. It is a complete and free replacement of PGP and
can be used to encrypt data and to create digital signatures. It
includes an advanced key management facility, samrtcard support and is
compliant with the OpenPGP Internet standard as described by RFC-4880
(the recently released update of RFC-2440).
Note that this version is from the GnuPG-1 series and thus smaller
than those from the GnuPG-2 series, easier to build and also better
portable. In contrast to GnuPG-2 (e.g version 2.0.8) it comes with no
support for S/MIME or other tools useful for desktop environments.
Fortunately you may install both versions alongside on the same system
without any conflict.
Getting the Software
Please follow the instructions found at http://www.gnupg.org/download/
or read on:
GnuPG 1.4.9 may be downloaded from one of the GnuPG mirror sites or
direct from ftp://ftp.gnupg.org/gcrypt/ . The list of mirrors can be
found at http://www.gnupg.org/mirrors.html . Note, that GnuPG is not
available at ftp.gnu.org.
On the mirrors you should find the following files in the *gnupg*
GnuPG source compressed using BZIP2 and OpenPGP signature.
GnuPG source compressed using GZIP and OpenPGP signature.
A patch file to upgrade a 1.4.8 GnuPG source.
Select one of them. To shorten the download time, you probably want to
get the BZIP2 compressed file. Please try another mirror if
exceptional your mirror is not yet up to date.
In the *binary* directory, you should find these files:
GnuPG compiled for Microsoft Windows and OpenPGP signature.
This is a command line only version; the source files are the
same as given above. Note, that this is a minimal installer and
unless you are just in need for the gpg binary, you are better
off using the full featured installer at http://www.gpg4win.org .
A new version of Gpg4win, including this version of GnuPG will
be available and announced soon.
Checking the Integrity
In order to check that the version of GnuPG which you are going to
install is an original and unmodified one, you can do it in one of
the following ways:
* If you already have a trusted version of GnuPG installed, you
can simply check the supplied signature. For example to check the
signature of the file gnupg-1.4.9.tar.bz2 you would use this command:
gpg --verify gnupg-1.4.9.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. Note, that you can retrieve the signing key using the command
finger wk ,at' g10code.com
or using a keyserver like
gpg --recv-key 1CE0C630
The distribution key 1CE0C630 is signed by the well known key
5B0358A2. If you get an key expired message, you should retrieve a
fresh copy as the expiration date might have been prolonged.
NEVER USE A GNUPG VERSION YOU JUST DOWNLOADED TO CHECK THE
INTEGRITY OF THE SOURCE - USE AN EXISTING GNUPG INSTALLATION!
* If you are not able to use an old version of GnuPG, you have to verify
the SHA-1 checksum. Assuming you downloaded the file
gnupg-1.4.9.tar.bz2, you would run the sha1sum command like this:
and check that the output matches the second line from the
* Improved AES encryption performance by more than 20% (on ia32).
Decryption is also a bit faster.
* Fixed possible memory corruption bug in 1.4.8 while importing
GnuPG comes with support for 28 languages. Due to a lot of new and
changed strings some translations are not entirely complete. The
Chinese (Simple and Traditional), Czech, Dutch, French, German,
Norwegian, Polish, Romanian, Russian, Spanish, Swedish and Turkish
translations are close to be complete.
Improving GnuPG is costly, but you can help! We are looking for
organizations that find GnuPG useful and wish to contribute back.
You can contribute by reporting bugs, improve the software, order
extensions or support or more general by donating money to the Free
Software movement (e.g. http://www.fsfeurope.org/help/donate.en.html).
Commercial support contracts for GnuPG are available, and they help
finance continued maintenance. g10 Code GmbH, a Duesseldorf based
company owned and headed by gpg's principal author, is currently
funding GnuPG development. We are always looking for interesting
