Hello!
We are pleased to announce the availability of a new GnuPG classic
release: Version 1.4.20. This release finally rejects all MD5 based
signatures; see below for details.
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
are available.
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
features.
- 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 platforms or if there is a need to handle PGP-2
messages. 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 1.4.20
==========================
* Reject signatures made using the MD5 hash algorithm unless the
new option --allow-weak-digest-algos or --pgp2 are given.
* New option --weak-digest to specify hash algorithms which
should be considered weak.
* Changed default cipher for symmetric-only encryption to AES-128.
* Fix for DoS when importing certain garbled secret keys.
* Improved error reporting for secret subkey w/o corresponding public
subkey.
* Improved error reporting in decryption due to wrong algorithm.
* Fix cluttering of stdout with trustdb info in double verbose mode.
* Pass a DBUS envvar to gpg-agent for use by gnome-keyring.
Getting the Software
====================
Please follow the instructions found at https://gnupg.org/download/ or
read on:
GnuPG 1.4.20 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
at ftp.gnu.org.
On ftp.gnupg.org you find these files:
ftp://ftp.gnupg.org/gcrypt/gnupg/gnupg-1.4.20.tar.bz2 (3606k)
ftp://ftp.gnupg.org/gcrypt/gnupg/gnupg-1.4.20.tar.bz2.sig
This is the GnuPG 1.4.20 source code compressed using BZIP2 and its
OpenPGP signature.
ftp://ftp.gnupg.org/gcrypt/gnupg/gnupg-1.4.20.tar.gz (5036k)
ftp://ftp.gnupg.org/gcrypt/gnupg/gnupg-1.4.20.tar.gz.sig
This is the same GnuPG 1.4.20 source code compressed using GZIP and its
OpenPGP signature.
ftp://ftp.gnupg.org/gcrypt/binary/gnupg-w32cli-1.4.20.exe (2359k)
ftp://ftp.gnupg.org/gcrypt/binary/gnupg-w32cli-1.4.20.exe.sig
This is GnuPG 1.4.20 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 .
To download the files via https use these URLs:
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-1.4.20.tar.bz2
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-1.4.20.tar.bz2.sig
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-1.4.20.tar.gz
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-1.4.20.tar.gz.sig
https://gnupg.org/ftp/gcrypt/binary/gnupg-w32cli-1.4.20.exe
https://gnupg.org/ftp/gcrypt/binary/gnupg-w32cli-1.4.20.exe.sig
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-1.4.20.tar.bz2 you would use this command:
gpg --verify gnupg-1.4.20.tar.bz2.sig gnupg-1.4.20.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-1.4.20.tar.bz2, you would run the command like this:
sha1sum gnupg-1.4.20.tar.bz2
and check that the output matches the first line from the
following list:
cbc9d960e3d8488c32675019a79fbfbf8680387e gnupg-1.4.20.tar.bz2
359e464bcabbe370696e3dba45a1d63968c06ab3 gnupg-1.4.20.tar.gz
8f0c4760c9f38102f64a156744ec8a428298b92d gnupg-w32cli-1.4.20.exe
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:
2048R/4F25E3B6 2011-01-12 [expires: 2019-12-31]
Key fingerprint = D869 2123 C406 5DEA 5E0F 3AB5 249B 39D2 4F25 E3B6
