3 The GNU project is pleased to announce the availability of a new
4 stable GnuPG release: Version 2.0.0.
6 The GNU Privacy Guard (GnuPG) is GNU's tool for secure communication
7 and data storage. It can be used to encrypt data, create digital
8 signatures, help authenticating using Secure Shell and to provide a
9 framework for public key cryptography. It includes an advanced key
10 management facility and is compliant with the OpenPGP and S/MIME
13 GnuPG-2 has a different architecture than GnuPG-1 (e.g. 1.4.5) in that
14 it splits up functionality into several modules. However, both
15 versions may be installed alongside without any conflict. In fact,
16 the gpg version from GnuPG-1 is able to make use of the gpg-agent as
17 included in GnuPG-2 and allows for seamless passphrase caching. The
18 advantage of GnuPG-1 is its smaller size and the lack of dependency on
19 other modules at run and build time. We will keep maintaining GnuPG-1
20 versions because they are very useful for small systems and for server
21 based applications requiring only OpenPGP support.
23 GnuPG is distributed under the terms of the GNU General Public License
24 (GPL). GnuPG-2 works best on GNU/Linux or *BSD systems. Other POSIX
25 compliant systems are also supported but have not yet been tested very
32 * The *gpg-agent* is the central place to maintain private keys and
33 to cache passphrases. It is implemented as a daemon to be started
36 * *gpgsm* is an implementation of the X.509 and CMS standards and
37 provides the cryptographic core to implement the S/MIME protocol.
38 The command line interface is very similar to the one of gpg. This
39 helps adding S/MIME to application currently providing OpenPGP
42 * *scdaemon* is a daemon run by gpg-agent to access different types
43 of smart cards using a unified interface.
45 * *gpg-connect-agent* is a tool to help scripts directly accessing
46 services of gpg-agent and scdaemon.
48 * *gpgconf* is a tool to maintain the configuration files of all
49 modules using a well defined API.
51 * Support for Dirmngr, a separate package to maintain certificate
52 revocation lists, do OCSP requests and to run LDAP queries.
54 * Support for the Secure Shell Agent protocol. In fact, gpg-agent
55 may be used as full replacement of the commonly used ssh-agent
58 * Smart card support for the Secure Shell.
60 * Documentation is now done in Texinfo. Thus besides Info, HTML and
61 PDF versions may easily be generated.
63 * Man pages for all tools.
69 Please follow the instructions found at http://www.gnupg.org/download/
72 GnuPG 2.0.0 may be downloaded from one of the GnuPG mirror sites or
73 direct from ftp://ftp.gnupg.org/gcrypt/ . The list of mirrors can be
74 found at http://www.gnupg.org/mirrors.html . Note, that GnuPG is not
75 available at ftp.gnu.org.
77 On the mirrors you should find the following files in the *gnupg*
80 gnupg-2.0.0.tar.bz2 (3.8M)
81 gnupg-2.0.0.tar.bz2.sig
83 GnuPG source compressed using BZIP2 and OpenPGP signature.
85 Please try another mirror if exceptional your mirror is not yet up to
86 date. GnuPG-2 requires a couple of libraries to be installed; see the
87 README file or the output of the configure run for details.
90 Checking the Integrity
91 ======================
93 In order to check that the version of GnuPG which you are going to
94 install is an original and unmodified one, you can do it in one of
97 * If you already have a trusted version of GnuPG installed, you
98 can simply check the supplied signature. For example to check the
99 signature of the file gnupg-2.0.0.tar.bz2 you would use this command:
101 gpg --verify gnupg-2.0.0.tar.bz2.sig
103 This checks whether the signature file matches the source file.
104 You should see a message indicating that the signature is good and
105 made by that signing key. Make sure that you have the right key,
106 either by checking the fingerprint of that key with other sources
107 or by checking that the key has been signed by a trustworthy other
108 key. Note, that you can retrieve the signing key using the command
110 finger wk ,at' g10code.com
112 or using a key server like
114 gpg --recv-key 1CE0C630
116 The distribution key 1CE0C630 is signed by the well known key
117 5B0358A2. If you get an key expired message, you should retrieve a
118 fresh copy as the expiration date might have been prolonged.
120 NEVER USE A GNUPG VERSION YOU JUST DOWNLOADED TO CHECK THE
121 INTEGRITY OF THE SOURCE - USE AN EXISTING GNUPG INSTALLATION!
123 * If you are not able to use an existing version of GnuPG, you have
124 to verify the SHA-1 checksum. Assuming you downloaded the file
125 gnupg-2.0.0.tar.bz2, you would run the sha1sum command like this:
127 sha1sum gnupg-2.0.0.tar.bz2
129 and check that the output matches this:
131 c335957368ea88bcb658922e7d3aae7e3ac6896d gnupg-2.0.0.tar.bz2
137 GnuPG comes with support for 27 languages. Due to a lot of new and
138 changed strings most translations are not entirely complete. However
139 the Turkish and German translators have been very fast in completing
140 their translations. The Russian one came in just a few hours too
141 late. Updates of the other translations are expected for the next
148 We are currently working on an installation guide to explain in more
149 detail how to configure the new features. As of now the chapters on
150 gpg-agent and gpgsm include brief information on how to set up the
151 whole thing. Please watch the GnuPG website for updates of the
152 documentation. In the meantime you may search the GnuPG mailing list
153 archives or ask on the gnupg-users mailing lists for advise on how to
154 solve problems. Many of the new features are around for several years
155 and thus enough public knowledge is already available.
161 Improving GnuPG is costly, but you can help! We are looking for
162 organizations that find GnuPG useful and wish to contribute back. You
163 can contribute by reporting bugs, improve the software, or by donating
166 Commercial support contracts for GnuPG are available, and they help
167 finance continued maintenance. g10 Code GmbH, a Duesseldorf based
168 company owned and headed by GnuPG's principal author, is currently
169 funding GnuPG development. We are always looking for interesting
170 development projects.

180 We have to thank all the people who helped with this release, be it
181 testing, coding, translating, suggesting, auditing, administering the
182 servers, spreading the word or answering questions on the mailing
