* 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 <solar@openwall.com> in 1998-2001, and placed
* in the public domain.
*
* There's absolutely no warranty.
*
* It is my intent that you should be able to use this on your system,
* as a 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 compatible with OpenBSD bcrypt.c (version 2a)
* by Niels Provos <provos@physnet.uni-hamburg.de>, and uses some of his
* ideas. The password hashing algorithm was designed by David Mazieres
* <dm@lcs.mit.edu>.
*
* 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).

* This is an original implementation of the DES and the crypt(3) interfaces
* by David Burren <davidb@werj.com.au>.
*
* An excellent reference on the underlying algorithm (and related
* algorithms) is:
*
* B. Schneier, Applied Cryptography: protocols, algorithms,
* and source code in C, John Wiley & Sons, 1994.
*
* Note that in that book's description of DES the lookups for the initial,
* pbox, and final permutations are inverted (this has been brought to the
* attention of the author). A list of errata for this book has been
* posted to the sci.crypt newsgroup by the author and is available for FTP.
*
* ARCHITECTURE ASSUMPTIONS:
* It is assumed that the 8-byte arrays passed by reference can be
* addressed as arrays of uint32's (ie. the CPU is not picky about
* alignment).
