We are pleased to announce the availability of a new GnuPG release:
version 2.3.2.  This is the third release in the new 2.3 series which
fixes a couple of bugs and adds a few new things.  See below for

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 is Free Software (meaning that it respects your freedom).  It can
be freely used, modified and distributed under the terms of the GNU
General Public License.

Three different series of GnuPG are actively maintained:

- Version 2.3 is the latest development series with a lot of new
  features.  This announcement is about the latest release of this

- Version 2.2 is our LTS (long term support) version and guaranteed to
  be maintained at least until the end of 2024.
  See https://gnupg.org/download/index.html#end-of-life

- Version 1.4 is maintained to allow decryption of very old data which
  is, for security reasons, not anymore possible with other GnuPG

Getting the Software

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

GnuPG 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-2.3.2.tar.bz2 (7411k)

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-w32-2.3.2_20210824.exe (4586k)

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

If you want to use this GnuPG versions with Gpg4win simply install it on
on top of Gpg4win 3.1.16.

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-2.3.2.tar.bz2 you would use this command:

     gpg --verify gnupg-2.3.2.tar.bz2.sig gnupg-2.3.2.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-2.3.2.tar.bz2, you run the command like this:

     sha1sum gnupg-2.3.2.tar.bz2

   and check that the output matches the next line:

f0f44b29e3702d3be1b25c964dfc2aaefe70e2fc  gnupg-2.3.2.tar.bz2
7c8ff377310f9781b89efb06222e7e74a19ed477  gnupg-w32-2.3.2_20210824.tar.xz
f6c1591e06ee2801961e216f44bc67243e87576f  gnupg-w32-2.3.2_20210824.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.

Documentation and Support

The file gnupg.info has the complete reference manual of the system.
Separate man pages are included as well but they miss some of the
details available only in the manual.  The manual is also available
online at


or can be downloaded as PDF at


You may also want to search the GnuPG mailing list archives or ask on
the gnupg-users mailing list for advise on how to solve problems.  Most
of the new features are around for several years and thus enough public
experience is available.  https://wiki.gnupg.org has user contributed
information around GnuPG and relate software.

If you are a developer and you need a certain feature for your project,
please do not hesitate to bring it to the gnupg-devel mailing list for


Since 2001 maintenance and development of GnuPG is done by g10 Code GmbH
and still mostly financed by donations.  Three full-time 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

The financial support of the governmental CERT of Luxembourg
(GOVCERT.LU) allowed us to develop new and improved features for
smartcards (Yubikey, PIV and Scute) as well as various usability
features.  Thanks.

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

Happy hacking,

   Your GnuPG hackers
