We are pleased to announce the availability of a new stable GnuPG-1
release: Version 1.4.10.  

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 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 2.0.12) 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 1.4.10 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-1.4.10.tar.bz2 (3331k)

      GnuPG source compressed using BZIP2 and OpenPGP signature.

  gnupg-1.4.10.tar.gz (4636k)

      GnuPG source compressed using GZIP and OpenPGP signature.

  gnupg-1.4.9-1.4.10.diff.bz2 (189k)

      A patch file to upgrade a 1.4.9 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-w32cli-1.4.10.exe (1531k)

      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 .

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-1.4.10.tar.bz2 you would use this command:

     gpg --verify gnupg-1.4.10.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.


 * 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-1.4.10.tar.bz2, you would run the sha1sum command like this:

     sha1sum gnupg-1.4.10.tar.bz2

   and check that the output matches the second line from the
   following list:

fd1b6a5f3b2dd836b598a1123ac257b8f105615d  gnupg-1.4.10.tar.bz2
0db579b2dc202213424f55243906b71228dd18d1  gnupg-1.4.10.tar.gz
4a6b9f8b15d9849307a90f2b35bde8fd2d111331  gnupg-1.4.9-1.4.10.diff.bz2
c4383992b4815311e523d2f12684d47b7a552fca  gnupg-w32cli-1.4.10.exe

What's New

    * 2048 bit RSA keys are now generated by default.  The default
      hash algorithm preferences has changed to prefer SHA-256 over
      SHA-1.  2048 bit DSA keys are now generated to use a 256 bit
      hash algorithm

    * Support v2 OpenPGP cards.

    * The algorithm to compute the SIG_ID status has been changed to
      match the one from 2.0.10.

    * Improved file locking.  Implemented it for W32.

    * Fixed a memory leak which made imports of many keys very slow.

    * Many smaller bug fixes.

    * Support for the Camellia cipher (RFC-5581).

    * Support for HKP keyservers over SSL ("HKPS").


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
development projects.

We have to thank all the people who helped with this release, be it
testing, coding, translating, suggesting, auditing, administering the
servers, spreading the word or answering questions on the mailing

Happy Hacking,

  The GnuPG Team (David, Werner and the other contributors)
