The GNU Privacy Guard 2 ========================= Version 2.1 Copyright 1997-2015 Werner Koch Copyright 1998-2015 Free Software Foundation, Inc. * INTRODUCTION GnuPG is a complete and free implementation of the OpenPGP standard as defined by RFC4880 (also known as PGP). GnuPG allows to encrypt and sign data and communication, features a versatile key management system as well as access modules for public key directories. GnuPG, also known as GPG, 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. Since version 2 GnuPG provides support for S/MIME and Secure Shell in addition to OpenPGP. 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. We are currently maintaining three branches of GnuPG: - 2.1 (i.e. this release) is the latest development with a lot of new features. - 2.0 is the current stable version for general use. - 1.4 is the old standalone version which is most suitable for older or embedded platforms. You may not install 2.1 and 2.0 at the same time. However, it is possible to install 1.4 along with any of the 2.x versions. * BUILD INSTRUCTIONS GnuPG 2.1 depends on the following GnuPG related packages: npth (ftp://ftp.gnupg.org/gcrypt/npth/) libgpg-error (ftp://ftp.gnupg.org/gcrypt/libgpg-error/) libgcrypt (ftp://ftp.gnupg.org/gcrypt/libgcrypt/) libksba (ftp://ftp.gnupg.org/gcrypt/libksba/) libassuan (ftp://ftp.gnupg.org/gcrypt/libassuan/) You should get the latest versions of course, the GnuPG configure script complains if a version is not sufficient. For some advanced features several other libraries are required. The configure script prints diagnostic messages if one of these libraries is not available and a feature will not be available.. You also need the Pinentry package for most functions of GnuPG; however it is not a build requirement. Pinentry is available at ftp://ftp.gnupg.org/gcrypt/pinentry/ . After building and installing the above packages in the order as given above, you may continue with GnuPG installation (you may also just try to build GnuPG to see whether your already installed versions are sufficient). As with all packages, you just have to do ./configure make make install (Before doing install you might need to become root.) If everything succeeds, you have a working GnuPG with support for OpenPGP, S/MIME, ssh-agent, and smartcards. Note that there is no binary gpg but a gpg2 so that this package won't conflict with a GnuPG 1.4 installation. gpg2 behaves just like gpg. In case of problem please ask on the gnupg-users@gnupg.org mailing list for advise. Instruction on how to build for Windows can be found in the file doc/HACKING in the section "How to build an installer for Windows". This requires some experience as developer. Note that the PKITS tests are always skipped unless you copy the PKITS test data file into the tests/pkits directory. There is no need to run these test and some of them may even fail because the test scripts are not yet complete. You may run gpgconf --list-dirs to view the default directories used by GnuPG. To quickly build all required software without installing it, the Speedo method may be used: make -f build-aux/speedo.mk native This method downloads all required libraries and does a native build of GnuPG to PLAY/inst/. GNU make is required and you need to set LD_LIBRARY_PATH to $(pwd)/PLAY/inst/lib to test the binaries. ** Specific build problems on some machines: *** Apple OSX 10.x using XCode On some versions the correct location of a header file can't be detected by configure. To fix that you should run configure like this ./configure gl_cv_absolute_stdint_h=/usr/include/stdint.h Add other options as needed. * MIGRATION from 1.4 or 2.0 to 2.1 The major change in 2.1 is gpg-agent taking care of the OpenPGP secret keys (those managed by GPG). The former file "secring.gpg" will not be used anymore. Newly generated keys are stored in the agent's key store directory "~/.gnupg/private-keys-v1.d/". The first time gpg needs a secret key it checks whether a "secring.gpg" exists and copies them to the new store. The old secring.gpg is kept for use by older versions of gpg. Note that gpg-agent now uses a fixed socket. All tools will start the gpg-agent as needed. The formerly used environment variable GPG_AGENT_INFO is ignored by 2.1. The SSH_AUTH_SOCK environment variable should be set to a fixed value. The Dirmngr is now part of GnuPG proper and also used to access OpenPGP keyservers. The directory layout of Dirmngr changed to make use of the GnuPG directories. Dirmngr is started by gpg or gpgsm as needed. There is no more need to install a separate Dirmngr package. * DOCUMENTATION The complete documentation is in the texinfo manual named `gnupg.info'. Run "info gnupg" to read it. If you want a a printable copy of the manual, change to the "doc" directory and enter "make pdf" For a HTML version enter "make html" and point your browser to gnupg.html/index.html. Standard man pages for all components are provided as well. An online version of the manual is available at [[https://gnupg.org/documentation/manuals/gnupg/]] . A version of the manual pertaining to the current development snapshot is at [[https://gnupg.org/documentation/manuals/gnupg-devel/]] . * GnuPG 1.4 and GnuPG 2.0 GnuPG 2.0 is a newer version of GnuPG with additional support for S/MIME. It has a different design philosophy that splits functionality up into several modules. Both versions may be installed simultaneously without any conflict (gpg is called gpg2 in GnuPG 2). In fact, the gpg version from GnuPG 1.4 is able to make use of the gpg-agent as included in GnuPG 2 and allows for seamless passphrase caching. The advantage of GnuPG 1.4 is its smaller size and no dependency on other modules at run and build time. * HOW TO GET MORE INFORMATION A description of new features and changes in version 2.1 can be found in the file "doc/whats-new-in-2.1.txt" and online at "https://gnupg.org/faq/whats-new-in-2.1.html" . The primary WWW page is "https://www.gnupg.org" or using Tor "http://ic6au7wa3f6naxjq.onion" The primary FTP site is "ftp://ftp.gnupg.org/gcrypt/" See [[https://gnupg.org/download/mirrors.html]] for a list of mirrors and use them if possible. You may also find GnuPG mirrored on some of the regular GNU mirrors. We have some mailing lists dedicated to GnuPG: gnupg-announce@gnupg.org For important announcements like new versions and such stuff. This is a moderated list and has very low traffic. Do not post to this list. gnupg-users@gnupg.org For general user discussion and help (English). gnupg-de@gnupg.org German speaking counterpart of gnupg-users. gnupg-ru@gnupg.org Russian speaking counterpart of gnupg-users. gnupg-devel@gnupg.org GnuPG developers main forum. You subscribe to one of the list by sending mail with a subject of "subscribe" to x-request@gnupg.org, where x is the name of the mailing list (gnupg-announce, gnupg-users, etc.). See https://www.gnupg.org/documentation/mailing-lists.html for archives of the mailing lists. Please direct bug reports to http://bugs.gnupg.org or post them direct to the mailing list <gnupg-devel@gnupg.org>. Please direct questions about GnuPG to the users mailing list or one of the PGP newsgroups; please do not direct questions to one of the authors directly as we are busy working on improvements and bug fixes. The English and German mailing lists are watched by the authors and we try to answer questions when time allows us. Commercial grade support for GnuPG is available; for a listing of offers see https://www.gnupg.org/service.html . Maintaining and improving GnuPG requires a lot of time. Since 2001, g10 Code GmbH, a German company owned and headed by GnuPG's principal author Werner Koch, is bearing the majority of these costs. To keep GnuPG in a healthy state, they need your support.
