We are pleased to announce the availability of a new stable GnuPG
release: Version 1.2.5
The GNU Privacy Guard (GnuPG) is GNU's tool for secure
communication and data storage. It is a complete and free
replacement of PGP and can be used to encrypt data and to create
digital signatures. It includes an advanced key management facility
and is compliant with the proposed OpenPGP Internet standard as
described in RFC2440.
This is mainly a bug fix release; for details see the "What's
New" section below.
Getting the Software
Please follow the instructions found at http://www.gnupg.org/download/
or read on:
GnuPG 1.2.5 may be downloaded from one of the GnuPG mirror sites
or direct from ftp://ftp.gnupg.org/gcrypt. The
list of mirrors can be found at http://www.gnupg.org/mirrors.html.
Note, that GnuPG is not available at ftp.gnu.org/.
On the mirrors you should find the following files in the
GnuPG source compressed using BZIP2 and OpenPGP signature.
GnuPG source compressed using GZIP and OpenPGP signature.
A patch file to upgrade a 1.2.4 GnuPG source. This file
is signed; you have to use GnuPG > 0.9.5 to verify the
signature. GnuPG has a feature to allow clear signed patch files
which can still be processed by the patch utility.
Select one of them. To shorten the download time, you probably
want to get the BZIP2 compressed file. Please try another mirror if
exceptional your mirror is not yet up to date.
In the binary directory, you should find these
GnuPG compiled for Microsoft Windows and OpenPGP
signature. Note that this is a command line version and comes
without a graphical installer tool. You have to use an UNZIP
utility to extract the files and install them manually. The
included file README.W32 has further instructions.
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 trusted version of GnuPG installed, you
can simply check the supplied signature. For example to check the
signature of the file gnupg-1.2.4.tar.bz2 you would use this
gpg --verify gnupg-1.2.5.tar.bz2.sig
This checks whether the signature file matches the source file.
You should see a message indicating that the signature is good and
made by that signing key. Make sure that you have the right key,
either by checking the fingerprint of that key with other sources
or by checking that the key has been signed by a trustworthy other
key. Note, that you can retrieve the signing key using "finger wk
'at' g10code.com" or "dd9jn 'at' gnu.org" or using the keyservers. I recently
prolonged the expiration date; thus you might need a fresh copy of
Never use a GnuPG version you just downloaded to check the
integrity of the source - use an existing GnuPG installation!
- If you are not able to use an old version of GnuPG, you have to
verify the MD5 checksum. Assuming you downloaded the file
gnupg-1.2.5.tar.bz2, you would run the md5sum command like
and check that the output matches the first line from the
If you are upgrading from a version prior to 1.0.7, you should
run the script tools/convert-from-106 once. Please note also that
due to a bug in versions prior to 1.0.6 it may not be possible to
downgrade to such versions unless you apply the patch http://www.gnupg.org/developer/gpg-woody-fix.txt
If you have any problems, please see the FAQ and the mailing
list archive at http://lists.gnupg.org. Please direct
questions to the firstname.lastname@example.org mailing
Here is a list of major user visible changes since 1.2.4:
- New --ask-cert-level/--no-ask-cert-level option to turn on and
off the prompt for signature level when signing a key. Defaults to
- New --min-cert-level option to disregard key signatures that
are under a specified level. Defaults to 1 (i.e. don't disregard
- New --max-output option to limit the amount of plaintext output
generated by GnuPG. This option can be used by programs which call
GnuPG to process messages that may result in plaintext larger than
the calling program is prepared to handle. This is sometimes called
a "Decompression Bomb".
- New --list-config command for frontends and other programs that
call GnuPG. See doc/DETAILS for the specifics of this.
- New --gpgconf-list command for internal use by the gpgconf
utility from gnupg 1.9.x.
- Some performance improvements with large keyrings. See
--enable-key-cache=3DSIZE in the README file for details.
- Some portability fixes for the OpenBSD/i386, HPPA, and AIX
- Simplified Chinese translation.
GnuPG comes with support for 28 languages:
||Brazilian Portuguese (pt_BR)[*]
||Traditional Chinese (zh_TW)[*]
||Simplified Chinese (zh_CN)
Languages marked with [*] were not updated for this release and
you may notice untranslated messages. Many thanks to the
translators for their ongoing support of GnuPG.
GnuPG 1.2.x is the current stable branch and won't undergo any
serious changes. We will just fix bugs and add compatibility fixes
GnuPG 1.3.x is the version were we do most new stuff and it will
lead to the next stable version 1.4 not too far away.
GnuPG 1.9.x is next generation GnuPG. This version merged the
code Fromthe Aegypten project and thus it includes the gpg-agent, a
smartcard daemon and gpg's S/MIME cousin gpgsm. The design is
different to the previous versions and we may not support all
ancient systems - thus POSIX compatibility will be an absolute
requirement for supported platforms. 1.9 is based on an somewhat
older 1.3 code and will peacefully coexist with other GnuPG
