============

Libgcrypt used to be part of GnuPG but has been taken out into its own
package on 2000-12-21.

Most of the stuff in mpi has been taken from an old GMP library
version by Torbjorn Granlund <tege@noisy.tmg.se>.

The files cipher/rndunix.c and cipher/rndw32.c are based on those
files from Cryptlib.  Copyright Peter Gutmann, Paul Kendall, and Chris
Wedgwood 1996-1999.

The ECC code cipher/ecc.c was based on code by Sergi Blanch i Torne,
sergi at calcurco dot org.

The implementation of the Camellia cipher has been been taken from the
original NTT provided GPL source.

The CAVS testing program tests/cavs_driver.pl is not to be considered
a part of libgcrypt proper.  We distribute it merely for convenience.
It has a permissive license and is copyrighted by atsec information
security corporation.  See the file for details.

The file salsa20.c is based on D.J. Bernstein's public domain code and
taken from Nettle.  Copyright 2012 Simon Josefsson and Niels Möller.

License:

Most of the package is licensed under the GNU Lesser General Public 
License (LGPL) version 2.1 (or later), except for helper and debugging
binaries. See below for details. The documentation is licensed under
the GPLv2 (or later), see below.

Excerpt from upstream's README:

    The library is distributed under the terms of the GNU Lesser
    General Public License (LGPL); see the file COPYING.LIB for the
    actual terms.  The helper programs (e.g. gcryptrnd and getrandom)
    as well as the documentation are distributed under the terms of
    the GNU General Public License (GPL); see the file COPYING for the
    actual 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.
