Introduction
--------------

GnuPG Made Easy (GPGME) is a C language library that allows to add
support for cryptography to a program.  It is designed to make access
to public key crypto engines like GnuPG or GpgSM easier for
applications.  GPGME provides a high-level crypto API for encryption,
decryption, signing, signature verification and key management.

GPGME comes with language bindings for Common Lisp, C++, QT, Python2,
and Python 3.

GPGME uses GnuPG as its backend to support OpenPGP and the
Cryptographic Message Syntax (CMS).

See the files COPYING, COPYING.LESSER, and each file for copyright and
warranty information.  The file AUTHORS has a list of authors and
useful web and mail addresses.


Installation
--------------

See the file INSTALL for generic installation instructions.

Check that you have unmodified sources.  See below on how to do this.
Don't skip it - this is an important step!

To build GPGME, you need to install libgpg-error (>= 1.24) and
Libassuan (>= 2.4.2).

For support of the OpenPGP and the CMS protocols, you should use the
latest version of GnuPG (>= 2.1.18) , available at:
https://gnupg.org/ftp/gcrypt/gnupg/.

For building the Git version of GPGME please see the file README.GIT
for more information.


How to Verify the Source
--------------------------

In order to check that the version of GPGME which you are going to
install is an original and unmodified one, you can do it in one of the
following ways:

a) If you have a trusted Version of GnuPG installed, you can simply check
   the supplied signature:

	$ gpg --verify gpgme-x.y.z.tar.gz.sig gpgme-x.y.z.tar.gz

   This checks that the detached signature gpgme-x.y.z.tar.gz.sig is
   indeed a a signature of gpgme-x.y.z.tar.gz.  The key used to create
   this signature is at least one of:

     rsa2048 2011-01-12 [expires: 2019-12-31]
     Key fingerprint = D869 2123 C406 5DEA 5E0F  3AB5 249B 39D2 4F25 E3B6
     Werner Koch (dist sig)

     rsa2048 2014-10-29 [expires: 2019-12-31]
     Key fingerprint = 46CC 7308 65BB 5C78 EBAB  ADCF 0437 6F3E E085 6959
     David Shaw (GnuPG Release Signing Key) <dshaw 'at' jabberwocky.com>

     rsa2048 2014-10-29 [expires: 2020-10-30]
     Key fingerprint = 031E C253 6E58 0D8E A286  A9F2 2071 B08A 33BD 3F06
     NIIBE Yutaka (GnuPG Release Key) <gniibe 'at' fsij.org>

     rsa3072 2017-03-17 [expires: 2027-03-15]
     Key fingerprint = 5B80 C575 4298 F0CB 55D8  ED6A BCEF 7E29 4B09 2E28
     Andre Heinecke (Release Signing Key)

   The keys are available at <https://gnupg.org/signature_key.html>
   and in released GnuPG tarballs in the file g10/distsigkey.gpg .
   You have to make sure that these are really the desired keys and
   not faked one.  You should do this by comparing the fingerprints
   with the fingerprints published elsewhere.

b) If you don't have any of the above programs, you have to verify
   the SHA1 checksum:

	$ sha1sum gpgme-x.y.z.tar.gz

   This should yield an output _similar_ to this:

   fd9351b26b3189c1d577f0970f9dcadc3412def1  gpgme-x.y.z.tar.gz

   Now check that this checksum is _exactly_ the same as the one
   published via the announcement list and probably via Usenet.


Documentation
---------------

For information how to use the library you can read the info manual,
which is also a reference book, in the doc/ directory.  The programs
in the tests/ directory may also prove useful.

Please subscribe to the gnupg-devel@gnupg.org mailing list if you want
to do serious work.

For hacking on GPGME, please have a look at doc/HACKING.
