Hello!
|
||
|
|
||
|
The GNU project is pleased to announce the availability of a new
|
||
|
stable GnuPG release: Version 2.0.0.
|
||
|
|
||
|
The GNU Privacy Guard (GnuPG) is GNU's tool for secure communication
|
||
|
and data storage. It can be used to encrypt data, create digital
|
||
|
signatures, help authenticating using Secure Shell and to provide a
|
||
|
framework for public key cryptography. It includes an advanced key
|
||
|
management facility and is compliant with the OpenPGP and S/MIME
|
||
|
standards.
|
||
|
|
||
|
GnuPG-2 has a different architecture than GnuPG-1 (e.g. 1.4.5) in that
|
||
|
it splits up functionality into several modules. However, both
|
||
|
versions may be installed alongside without any conflict. In fact,
|
||
|
the gpg version from GnuPG-1 is able to make use of the gpg-agent as
|
||
|
included in GnuPG-2 and allows for seamless passphrase caching. The
|
||
|
advantage of GnuPG-1 is its smaller size and the lack of dependency on
|
||
|
other modules at run and build time. We will keep maintaining GnuPG-1
|
||
|
versions because they are very useful for small systems and for server
|
||
|
based applications requiring only OpenPGP support.
|
||
|
|
||
|
GnuPG is distributed under the terms of the GNU General Public License
|
||
|
(GPL). GnuPG-2 works best on GNU/Linux or *BSD systems. Other POSIX
|
||
|
compliant systems are also supported but have not yet been tested very
|
||
|
well.
|
||
|
|
||
|
|
||
|
What's New in GnuPG-2
|
||
|
=====================
|
||
|
|
||
|
* The *gpg-agent* is the central place to maintain private keys and
|
||
|
to cache passphrases. It is implemented as a daemon to be started
|
||
|
with a user session.
|
||
|
|
||
|
* *gpgsm* is an implementation of the X.509 and CMS standards and
|
||
|
provides the cryptographic core to implement the S/MIME protocol.
|
||
|
The command line interface is very similar to the one of gpg. This
|
||
|
helps adding S/MIME to application currently providing OpenPGP
|
||
|
support.
|
||
|
|
||
|
* *scdaemon* is a daemon run by gpg-agent to access different types
|
||
|
of smart cards using a unified interface.
|
||
|
|
||
|
* *gpg-connect-agent* is a tool to help scripts directly accessing
|
||
|
services of gpg-agent and scdaemon.
|
||
|
|
||
|
* *gpgconf* is a tool to maintain the configuration files of all
|
||
|
modules using a well defined API.
|
||
|
|
||
|
* Support for Dirmngr, a separate package to maintain certificate
|
||
|
revocation lists, do OCSP requests and to run LDAP queries.
|
||
|
|
||
|
* Support for the Secure Shell Agent protocol. In fact, gpg-agent
|
||
|
may be used as full replacement of the commonly used ssh-agent
|
||
|
daemon.
|
||
|
|
||
|
* Smart card support for the Secure Shell.
|
||
|
|
||
|
* Documentation is now done in Texinfo. Thus besides Info, HTML and
|
||
|
PDF versions may easily be generated.
|
||
|
|
||
|
* Man pages for all tools.
|
||
|
|
||

|
||
|
Getting the Software
|
||
|
====================
|
||
|
|
||
|
Please follow the instructions found at http://www.gnupg.org/download/
|
||
|
or read on:
|
||
|
|
||
|
GnuPG 2.0.0 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*
|
||
|
directory:
|
||
|
|
||
|
gnupg-2.0.0.tar.bz2 (3.8M)
|
||
|
gnupg-2.0.0.tar.bz2.sig
|
||
|
|
||
|
GnuPG source compressed using BZIP2 and OpenPGP signature.
|
||
|
|
||
|
Please try another mirror if exceptional your mirror is not yet up to
|
||
|
date. GnuPG-2 requires a couple of libraries to be installed; see the
|
||
|
README file or the output of the configure run for details.
|
||
|
|
||
|
|
||
|
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-2.0.0.tar.bz2 you would use this command:
|
||
|
|
||
|
gpg --verify gnupg-2.0.0.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 the command
|
||
|
|
||
|
finger wk ,at' g10code.com
|
||
|
|
||
|
or using a key server like
|
||
|
|
||
|
gpg --recv-key 1CE0C630
|
||
|
|
||
|
The distribution key 1CE0C630 is signed by the well known key
|
||
|
5B0358A2. If you get an key expired message, you should retrieve a
|
||
|
fresh copy as the expiration date might have been prolonged.
|
||
|
|
||
|
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 existing version of GnuPG, you have
|
||
|
to verify the SHA-1 checksum. Assuming you downloaded the file
|
||
|
gnupg-2.0.0.tar.bz2, you would run the sha1sum command like this:
|
||
|
|
||
|
sha1sum gnupg-2.0.0.tar.bz2
|
||
|
|
||
|
and check that the output matches this:
|
||
|
|
||
|
c335957368ea88bcb658922e7d3aae7e3ac6896d gnupg-2.0.0.tar.bz2
|
||
|
|
||
|
|
||
|
Internationalization
|
||
|
====================
|
||
|
|
||
|
GnuPG comes with support for 27 languages. Due to a lot of new and
|
||
|
changed strings most translations are not entirely complete. However
|
||
|
the Turkish and German translators have been very fast in completing
|
||
|
their translations. The Russian one came in just a few hours too
|
||
|
late. Updates of the other translations are expected for the next
|
||
|
releases.
|
||
|
|
||

|
Documentation
|
||
|
=============
|
||
|
|
||
|
We are currently working on an installation guide to explain in more
|
||
|
detail how to configure the new features. As of now the chapters on
|
||
|
gpg-agent and gpgsm include brief information on how to set up the
|
||
|
whole thing. Please watch the GnuPG website for updates of the
|
||
|
documentation. In the meantime you may search the GnuPG mailing list
|
||
|
archives or ask on the gnupg-users mailing lists for advise on how to
|
||
|
solve problems. Many of the new features are around for several years
|
||
|
and thus enough public knowledge is already available.
|
||
|
|
||
|
|
||
|
Support
|
||
|
=======
|
||
|
|
||
|
Improving GnuPG is costly, but you can help! We are looking for
|
||
|
organizations that find GnuPG useful and wish to contribute back. You
|
||
|
can contribute by reporting bugs, improve the software, or by donating
|
||
|
money.
|
||
|
|
||
|
Commercial support contracts for GnuPG are available, and they help
|
||
|
finance continued maintenance. g10 Code GmbH, a Duesseldorf based
|
||
|
company owned and headed by GnuPG's principal author, is currently
|
||
|
funding GnuPG development. We are always looking for interesting
|
||
|
development projects.
