We are pleased to announce the availability of a new GnuPG classic
release: Version 1.4.19. This release mitigates two new side channel
Updating any GnuPG 1.4 version to 1.4.19 is suggested!
To update a GnuPG 2.0 or 2.1 version you need to update the shared
library Libgcrypt to version 1.6.3.
What is GnuPG
The GNU Privacy Guard (GnuPG) is a complete and free implementation of
the OpenPGP standard as defined by RFC-4880 and better known as PGP.
GnuPG, also known as GPG, 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
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 versions of GnuPG are actively maintained:
- GnuPG "modern" (2.1) is the latest development with a lot of new
- GnuPG "stable" (2.0) is the current stable version for general use.
This is what most users are currently using.
- GnuPG "classic" (1.4) is the old standalone version which is most
suitable for older or embedded platforms. This announcement is about
a release of this version.
You may not install "modern" (2.1) and "stable" (2.0) at the same
time. However, it is possible to install "classic" (1.4) along with
any of the other versions.
What's New in GnuPG 1.4.19
* Use ciphertext blinding for Elgamal decryption [CVE-2014-3591].
See http://www.cs.tau.ac.il/~tromer/radioexp/ for details.
* Fixed data-dependent timing variations in modular exponentiation
[related to CVE-2015-0837, Last-Level Cache Side-Channel Attacks
* Detect faulty use of --verify on detached signatures.
* Changed the PKA method to use CERT records and hashed names.
* New import option "keep-ownertrust".
* Support algorithm names when generating keys using the --command-fd
* Updated many translations.
* Updated build system.
* Fixed a regression in keyserver import
* Fixed argument parsing for option --debug-level.
* Fixed DoS based on bogus and overlong key packets.
* Fixed bugs related to bogus keyrings.
* The usual minor minor bug fixes.
Getting the Software
Please follow the instructions found at https://gnupg.org/download/ or
GnuPG 1.4.19 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/mirrors.html . Note that GnuPG is not available
On ftp.gnupg.org you find these files:
This is the GnuPG 1.4.19 source code compressed using BZIP2 and its
This is the same GnuPG 1.4.19 source code compressed using GZIP and its
This is GnuPG 1.4.19 compiled for Microsoft Windows and its OpenPGP
signature. This is a command line only version; the source files are
the same as above. Note, that this is a minimal installer and unless
you are only in need for the simple the gpg binary, you are better off
using the full featured installer at https://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 version of GnuPG installed, you can simply
verify the supplied signature. For example to verify the signature
of the file gnupg-1.4.19.tar.bz2 you would use this command:
gpg --verify gnupg-1.4.19.tar.bz2.sig gnupg-1.4.19.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 below 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-1.4.19.tar.bz2, you would run the command like this:
and check that the output matches the first line from the
Release Signing Keys
To guarantee that a downloaded GnuPG version has not been tampered by
malicious entities we provide signature files for all tarballs and
binary versions. The keys are also signed by the long term keys of
their respective owners. Current releases are signed by one or more
of these four keys:

If you are a developer and you may need a certain feature for your
project, please do not hesitate to bring it to the gnupg-devel mailing
list for discussion.
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, and answering questions on the mailing
Since the start of the funding campaign in December several thousand
people have been kind enough to donate a total of 250000 Euro to support
this project. In addition the Linux Foundation gave a grant of $ 60000
for 2015, Stripe.com and Facebook.com each pledged $ 50000 per year.
I am amazed by this superb and unexpected support for the GnuPG project.
This does not only allow us to continue the project and allowed to hire
second full time developer, but also gives the resources to improve
things which have been delayed for too long.
*Thank you all !*
