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

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 .

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 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.

An example of the license headers of the LGPL is

  OCB is covered by several patents but may be used freely by most
  software.  See http://web.cs.ucdavis.edu/~rogaway/ocb/license.htm .
  In particular license 1 is suitable for Libgcrypt: See
  http://web.cs.ucdavis.edu/~rogaway/ocb/license1.pdf for the full
  license document; it basically says:

    License 1 — License for Open-Source Software Implementations of OCB
                (Jan 9, 2013)

    Under this license, you are authorized to make, use, and
    distribute open-source software implementations of OCB. This
    license terminates for you if you sue someone over their
    open-source software implementation of OCB claiming that you have
    a patent covering their implementation.



 License for Open Source Software Implementations of OCB
 January 9, 2013

 1 Definitions

 1.1 “Licensor” means Phillip Rogaway.

 1.2 “Licensed Patents” means any patent that claims priority to United
 States Patent Application No. 09/918,615 entitled “Method and Apparatus
 for Facilitating Efficient Authenticated Encryption,” and any utility,
 divisional, provisional, continuation, continuations-in-part, reexamination,
 reissue, or foreign counterpart patents that may issue with respect to the
 aforesaid patent application. This includes, but is not limited to, United
 States Patent No. 7,046,802; United States Patent No. 7,200,227; United
 States Patent No. 7,949,129; United States Patent No. 8,321,675 ; and any
 patent that issues out of United States Patent Application No. 13/669,114.

 1.3 “Use” means any practice of any invention claimed in the Licensed Patents.

 1.4 “Software Implementation” means any practice of any invention
 claimed in the Licensed Patents that takes the form of software executing on
 a user-programmable, general-purpose computer or that takes the form of a
 computer-readable medium storing such software. Software Implementation does
 not include, for example, application-specific integrated circuits (ASICs),
 field-programmable gate arrays (FPGAs), embedded systems, or IP cores.

 1.5 “Open Source Software” means software whose source code is published
 and made available for inspection and use by anyone because either (a) the
 source code is subject to a license that permits recipients to copy, modify,
 and distribute the source code without payment of fees or royalties, or
 (b) the source code is in the public domain, including code released for
 public use through a CC0 waiver. All licenses certified by the Open Source
 Initiative at opensource.org as of January 9, 2013 and all Creative Commons
 licenses identified on the creativecommons.org website as of January 9,
 2013, including the Public License Fallback of the CC0 waiver, satisfy these
 requirements for the purposes of this license.

 1.6 “Open Source Software Implementation” means a Software
 Implementation in which the software implicating the Licensed Patents is
 Open Source Software. Open Source Software Implementation does not include
 any Software Implementation in which the software implicating the Licensed
 Patents is combined, so as to form a larger program, with software that is
 not Open Source Software.

 2 License Grant

 2.1 License. Subject to your compliance with the term s of this license,
 including the restriction set forth in Section 2.2, Licensor hereby
 grants to you a perpetual, worldwide, non-exclusive, non-transferable,
 non-sublicenseable, no-charge, royalty-free, irrevocable license to practice
 any invention claimed in the Licensed Patents in any Open Source Software
 Implementation.

 2.2 Restriction. If you or your affiliates institute patent litigation
 (including, but not limited to, a cross-claim or counterclaim in a lawsuit)
 against any entity alleging that any Use authorized by this license
 infringes another patent, then any rights granted to you under this license
 automatically terminate as of the date such litigation is filed.

 3 Disclaimer
 YOUR USE OF THE LICENSED PATENTS IS AT YOUR OWN RISK AND UNLESS REQUIRED
 BY APPLICABLE LAW, LICENSOR MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
 KIND CONCERNING THE LICENSED PATENTS OR ANY PRODUCT EMBODYING ANY LICENSED
 PATENT, EXPRESS OR IMPLIED, STATUT ORY OR OTHERWISE, INCLUDING, WITHOUT
 LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, FITNESS FOR A PARTICULAR
 PURPOSE, OR NONINFRINGEMENT. IN NO EVENT WILL LICENSOR BE LIABLE FOR ANY
 CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN CONTRACT, TORT OR OTHERWISE,
 ARISING FROM OR RELATED TO ANY USE OF THE LICENSED PATENTS, INCLUDING,
 WITHOUT LIMITATION, DIRECT, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE
 OR SPECIAL DAMAGES, EVEN IF LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF
 SUCH DAMAGES PRIOR TO SUCH AN OCCURRENCE.
