Getting the Software
Please follow the instructions found at <https://gnupg.org/download/> or
GnuPG 2.2.3 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:
An installer for Windows without any graphical frontend except for a
very minimal Pinentry tool is available here:
The source used to build the Windows installer can be found in the same
directory with a ".tar.xz" suffix. A new Gpg4win 3.0 installer
featuring this version of GnuPG will be available 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 version of GnuPG installed, you can simply
verify the supplied signature. For example to verify the signature
of the file gnupg-2.2.3.tar.bz2 you would use this command:
gpg --verify gnupg-2.2.3.tar.bz2.sig gnupg-2.2.3.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-2.2.3.tar.bz2, you run the command like this:
and check that the output matches the next line:
This version of GnuPG has support for 26 languages with Chinese, Czech,
French, German, Japanese, Norwegian, Russian, and Ukrainian being almost

The GnuPG project currently employs one full-time developer and one
contractor. Both work exclusivly on GnuPG and closely related software
like Libgcrypt, GPGME, and GPA. We are planning to extend our team
again. Right now we are looking for an admin for our bug tracker; see
