    1.18 +
    1.19 +Introduction
    1.20 +--------------
    1.21 +
    1.22 +GnuPG Made Easy (GPGME) is a C language library that allows to add
    1.23 +support for cryptography to a program.  It is designed to make access
    1.24 +to public key crypto engines like GnuPG or GpgSM easier for
    1.25 +applications.  GPGME provides a high-level crypto API for encryption,
    1.26 +decryption, signing, signature verification and key management.
    1.27 +
    1.28 +GPGME uses GnuPG and GpgSM as its backends to support OpenPGP and the
    1.29 +Cryptographic Message Syntax (CMS).
    1.30 +
    1.31 +GPGME runs best on GNU/Linux or *BSD systems.  Other Unices may
    1.32 +require small portability fixes, please send us your patches.
    1.33 +
    1.34 +See the files COPYING, COPYING.LESSER, and each file for copyright and
    1.35 +warranty information.  The file AUTHORS has a list of authors and
    1.36 +useful web and mail addresses.
    1.37 +
    1.38 +
    1.39 +Installation
    1.40 +--------------
    1.41 +
    1.42 +See the file INSTALL for generic installation instructions.
    1.43 +
    1.44 +Check that you have unmodified sources.  See below on how to do this.
    1.45 +Don't skip it - this is an important step!
    1.46 +
    1.47 +To build GPGME, you need to install libgpg-error (>= 1.11) and
    1.48 +Libassuan (>= 2.0.2).
    1.49 +
    1.50 +For support of the OpenPGP protocol (default), you should use the
    1.51 +latest version of GnuPG (>= 1.4) , available at:
    1.52 +ftp://ftp.gnupg.org/gcrypt/gnupg/.  For support of the CMS
    1.53 +(Cryptographic Message Syntax) protocol and lot of other features, you
    1.54 +need a GnuPG version >= 2.0.
    1.55 +
    1.56 +For building the GIT version of GPGME please see the file README.GIT
    1.57 +for more information.
    1.58 +
    1.59 +
    1.60 +How to Verify the Source
    1.61 +--------------------------
    1.62 +
    1.63 +In order to check that the version of GPGME which you are going to
    1.64 +install is an original and unmodified one, you can do it in one of the
    1.65 +following ways:
    1.66 +
    1.67 +a) If you have a trusted Version of GnuPG installed, you can simply check
    1.68 +   the supplied signature:
    1.69 +
    1.70 +	$ gpg --verify gpgme-x.y.z.tar.gz.sig
    1.71 +
    1.72 +   This checks that the detached signature gpgme-x.y.z.tar.gz.sig is
    1.73 +   indeed a a signature of gpgme-x.y.z.tar.gz.  The key used to create
    1.74 +   this signature is either of:
    1.75 +
    1.76 +   "pub  2048R/4F25E3B6 2011-01-12 Werner Koch (dist sig)"
    1.77 +   "pub  1024D/87978569 1999-05-13
    1.78 +                        Marcus Brinkmann <Marcus.Brinkmann@ruhr-uni-bochum.de>
    1.79 +                        Marcus Brinkmann <mb@g10code.com>"
    1.80 +
    1.81 +   If you do not have this key, you can get it from any keyserver.  You
    1.82 +   have to make sure that this is really the key and not a faked one.
    1.83 +   You can do this by comparing the output of:
    1.84 +
    1.85 +	$ gpg --fingerprint 0x4F25E3B6
    1.86 +
    1.87 +   with the fingerprint published elsewhere.
    1.88 +
    1.89 +b) If you don't have any of the above programs, you have to verify
    1.90 +   the SHA1 checksum:
    1.91 +
    1.92 +	$ sha1sum gpgme-x.y.z.tar.gz
    1.93 +
    1.94 +   This should yield an output _similar_ to this:
    1.95 +
    1.96 +   fd9351b26b3189c1d577f0970f9dcadc3412def1  gpgme-x.y.z.tar.gz
    1.97 +
    1.98 +   Now check that this checksum is _exactly_ the same as the one
    1.99 +   published via the announcement list and probably via Usenet.
   1.100 +
   1.101 +
   1.102 +Documentation
   1.103 +---------------
   1.104 +
   1.105 +For information how to use the library you can read the info manual,
   1.106 +which is also a reference book, in the doc/ directory.  The programs
   1.107 +in the tests/gpg/ directory may also prove useful.
   1.108 +
   1.109 +Please subscribe to the gnupg-devel@gnupg.org mailing list if you want
   1.110 +to do serious work.
   1.111 +
   1.112 +For hacking on GPGME, please have a look at doc/HACKING.
