libgcrypt - The GNU crypto library
------------------------------------
Version 1.1
Copyright 2000, 2002 Free Software Foundation, Inc.
This file is free software; as a special exception the author gives
unlimited permission to copy and/or distribute it, with or without
modifications, as long as this notice is preserved.
This file is distributed in the hope that it will be useful, but
WITHOUT ANY WARRANTY, to the extent permitted by law; without even the
implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
THIS IS A DEVELOPMENT VERSION, THE FIRST STABLE VERSION WILL BE 1.2.0.
Overview
--------
Libgcrypt is a general purpose crypto library based on the code
used in GnuPG. We can't start with a new version number because
libgcrypt was part of gnupg 1.1 and some applications already used
it and tested for the version number. We believe that the API can
stay as it is, except that new functions may be added in the
future.
CVS
---
If you are using the CVS version, make sure that you have the
latest automake (I am using Debian Sid) and run ./autogen.sh to
create configure.
Mailing List
------------
You may want to join the developer's mailing list
gcrypt-devel@gnupg.org by sending mail with a subject of
"subscribe" to gcrypt-devel-request@gnupg.org. An archive of this
list is available at http://lists.gnupg.org .
License
-------
Most of this library is distributed under the terms of the GNU
Lesser General Public License (LGPL); see the file COPYING.LIB for
the actual terms. However some parts are distributed under the
GNU General Public License (GPL) so if you configure Libgcrypt to
include these modules, you have to comply with the conditions of
the GPL as found in the file COPYING. The modules under the GPL
are:
rndunix - Entropy gatherer for Unices without a /dev/random
rndw32 - Entropy gatherer for MS Windows
The documentation is available under the terms of the GNU Free
Documentation License; see the file COPYING.DOC for the terms.
This library used to be available under the GPL - this was changed
with version 1.1.7 with the rationale that there are now many free
crypto libraries available and many of them come with capabilities
similar to Libcrypt. We decided that to foster the use of
cryptography in Free Software an LGPLed library would make more
sense because it avoids problems due to license incompatibilities
between some Free Software licenses and the GPL.
Please note that in many cases it is better for a library to be
licensed under the GPL, so that it provides an advantage for free
software projects. The Lesser GPL is so named because it does
less to protect the freedom of the users of the code that it
covers. See http://www.gnu.org/philosophy/why-not-lgpl.html for
more explanation.
