We are pleased to announce the availability of a new GnuPG LTS release:
version 2.2.33.  This release fixes a few minor problems and brings a
few new options to ease user support and large scale installations.

The LTS (long term support) series of GnuPG is guaranteed to be
maintained at least until the end of 2024.  See

What is GnuPG

The GNU Privacy Guard (GnuPG, GPG) is a complete and free implementation
of the OpenPGP and S/MIME standards.

GnuPG allows to encrypt and sign data and communication, features a
versatile key management system as well as access modules for public key
directories.  GnuPG itself is a command line tool with features for easy
integration with other applications.  The separate library GPGME provides
a uniform API to use the GnuPG engine by software written in common
programming languages.  A wealth of frontend applications and libraries
making use of GnuPG are available.  As an universal crypto engine GnuPG
provides support for S/MIME and Secure Shell in addition to OpenPGP.

GnuPG can be freely used, modified and distributed under the terms of
the GNU General Public License.

  Release-info: https://dev.gnupg.org/T5641

  The provided Windows installer is now build against Libgpg-error 1.43
  and thus features versatile meta options for the config file.  For
  example, it is possible to read and use option values from the
  Registry or from environment variables.  More on this is in a not
  published written blog article.

Getting the Software

Please follow the instructions found at <https://gnupg.org/download/> or
read on:

GnuPG 2.2.33 may be downloaded from one of the GnuPG mirror sites or
direct from its primary FTP server.  The list of mirrors can be found at
<https://gnupg.org/download/mirrors.html>.  Note that GnuPG is not
available at ftp.gnu.org.

The GnuPG source code compressed using BZIP2 and its OpenPGP signature
are available here:

 https://gnupg.org/ftp/gcrypt/gnupg/gnupg-2.2.33.tar.bz2 (7068k)

An installer for Windows without any graphical frontend except for a
very minimal Pinentry tool is available here:

 https://gnupg.org/ftp/gcrypt/binary/gnupg-w32-2.2.33_20211123.exe (4424k)

The source used to build the Windows installer can be found in the same
directory with a ".tar.xz" suffix.

A new version of Gpg4win 3 will not be published.  Gpg4win users may
instead install this version on top of 3.1.16 or wait for Gpg4win 4.

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 version of GnuPG installed, you can simply
   verify the supplied signature.  For example to verify the signature
   of the file gnupg-2.2.33.tar.bz2 you would use this command:

     gpg --verify gnupg-2.2.33.tar.bz2.sig gnupg-2.2.33.tar.bz2

   This checks whether the signature file matches the source file.
   You should see a message indicating that the signature is good and
   made by one or more of the release signing keys.  Make sure that
   this is a valid key, either by matching the shown fingerprint
   against a trustworthy list of valid release signing keys or by
   checking that the key has been signed by trustworthy other keys.
   See the end of this mail for information on the signing keys.

 * If you are not able to use an existing version of GnuPG, you have
   to verify the SHA-1 checksum.  On Unix systems the command to do
   this is either "sha1sum" or "shasum".  Assuming you downloaded the
   file gnupg-2.2.33.tar.bz2, you run the command like this:

     sha1sum gnupg-2.2.33.tar.bz2

   and check that the output matches the next line:

70053b799a79139e0e7889282805fc889dd22540  gnupg-2.2.33.tar.bz2
6bf876e04ba00bebb64dffe7d2224206521948a7  gnupg-w32-2.2.33_20211123.tar.xz
c67151e92fc82bd4138ef441dbeba61e9bf4de5f  gnupg-w32-2.2.33_20211123.exe


This version of GnuPG has support for 26 languages with Chinese
(traditional and simplified), Czech, French, German, Italian,
Japanese, Norwegian, Polish, Russian, and Ukrainian being almost
completely translated.

Since 2001 maintenance and development of GnuPG is done by g10 Code GmbH

employed developers as well as two contractors exclusively work on GnuPG
and closely related software like Libgcrypt, GPGME and Gpg4win.

We like to thank all the nice people who are helping the GnuPG project,
be it testing, coding, translating, suggesting, auditing, administering
the servers, spreading the word, or answering questions on the mailing

Many thanks to our numerous financial supporters, both corporate and
individuals.  Without you it would not have been possible to keep GnuPG
in a good and secure shape and to address all the small and larger
requests made by our users.  Thanks.

Happy hacking,
