We are is pleased to announce the availability of a new GnuPG release:
version 2.2.1. This is a maintenance release; see below for a list of
The GNU Privacy Guard (GnuPG) is a complete and free implementation
of the OpenPGP standard which is commonly abbreviated as PGP.
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. 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
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.
Noteworthy changes in version 2.2.1
* gpg: Fix formatting of the user id in batch mode key generation
if only "name-email" is given.
* gpgv: Fix annoying "not suitable for" warnings.
* wks: Convey only the newest user id to the provider. This is the
case if different names are used with the same addr-spec.
* wks: Create a complying user id for provider policy mailbox-only.
* wks: Add workaround for posteo.de.
* scd: Fix the use of large ECC keys with an OpenPGP card.
* dirmngr: Use system provided root certificates if no specific HKP
certificates are configured. If build with GNUTLS, this was
already the case.
Further, the Windows installer has been built against an updated NTBTLS
libary which does now support ECC curves secp384r1, secp521r1, as well
as brainpool curves.
Getting the Software
Please follow the instructions found at <https://gnupg.org/download/> or
GnuPG 2.2.1 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. The new Gpg4win 3.0 installer
featuring this version of GnuPG will be available in a few days.
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-2.2.1.tar.bz2 you would use this command:
gpg --verify gnupg-2.2.1.tar.bz2.sig gnupg-2.2.1.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-2.2.1.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
If you used GnuPG in the past you should read the description of

details availabale only in thee manual. The manual is also available
