PCRE2 LICENCE

-------------



PCRE2 is a library of functions to support regular expressions whose syntax

and semantics are as close as possible to those of the Perl 5 language.



Releases 10.00 and above of PCRE2 are distributed under the terms of the "BSD"

licence, as specified below, with one exemption for certain binary

redistributions. The documentation for PCRE2, supplied in the "doc" directory,

is distributed under the same terms as the software itself. The data in the

testdata directory is not copyrighted and is in the public domain.



The basic library functions are written in C and are freestanding. Also

included in the distribution is a just-in-time compiler that can be used to

optimize pattern matching. This is an optional feature that can be omitted when

the library is built.

EXEMPTION FOR BINARY LIBRARY-LIKE PACKAGES

------------------------------------------



The second condition in the BSD licence (covering binary redistributions) does

not apply all the way down a chain of software. If binary package A includes

PCRE2, it must respect the condition, but if package B is software that

includes package A, the condition is not imposed on package B unless it uses

PCRE2 independently.

5. ext/standard crypt's blowfish implementation



The crypt_blowfish homepage is:



http://www.openwall.com/crypt/



This code comes from John the Ripper password cracker, with reentrant

and crypt(3) interfaces added, but optimizations specific to password

cracking removed.



Written by Solar Designer  in 1998-2011.

No copyright is claimed, and the software is hereby placed in the public

domain. In case this attempt to disclaim copyright and place the software

in the public domain is deemed null and void, then the software is

Copyright (c) 1998-2011 Solar Designer and it is hereby released to the

general public under the following terms:



Redistribution and use in source and binary forms, with or without

modification, are permitted.



There's ABSOLUTELY NO WARRANTY, express or implied.



It is my intent that you should be able to use this on your system,

as part of a software package, or anywhere else to improve security,

ensure compatibility, or for any other purpose. I would appreciate

it if you give credit where it is due and keep your modifications in

the public domain as well, but I don't require that in order to let

you place this code and any modifications you make under a license

of your choice.



This implementation is mostly compatible with OpenBSD's bcrypt.c (prefix

"$2a$") by Niels Provos , and uses some of his

ideas. The password hashing algorithm was designed by David Mazieres

. For more information on the level of compatibility,

please refer to the comments in BF_set_key() and to the crypt(3) man page

included in the crypt_blowfish tarball.



There's a paper on the algorithm that explains its design decisions:



http://www.usenix.org/events/usenix99/provos.html



Some of the tricks in BF_ROUND might be inspired by Eric Young's

Blowfish library (I can't be sure if I would think of something if I

hadn't seen his code).



6. ext/standard/rand



The following php_mt_...() functions are based on a C++ class MTRand by

Richard J. Wagner. For more information see the web page at

http://www-personal.engin.umich.edu/~wagnerr/MersenneTwister.html



Mersenne Twister random number generator -- a C++ class MTRand

Based on code by Makoto Matsumoto, Takuji Nishimura, and Shawn Cokus

Richard J. Wagner  v1.0  15 May 2003  [email protected]



The Mersenne Twister is an algorithm for generating random numbers.  It

was designed with consideration of the flaws in various other generators.

The period, 2^19937-1, and the order of equidistribution, 623 dimensions,

are far greater.  The generator is also fast; it avoids multiplication and

division, and it benefits from caches and pipelines.  For more information

see the inventors' web page at http://www.math.keio.ac.jp/~matumoto/emt.html

Equidistributed Uniform Pseudo-Random Number Generator", ACM Transactions on

Modeling and Computer Simulation, Vol. 8, No. 1, January 1998, pp 3-30.
