   * This implementation is mostly compatible with OpenBSD's bcrypt.c (prefix
   * "$2a$") by Niels Provos <provos at citi.umich.edu>, and uses some of his
   * ideas.  The password hashing algorithm was designed by David Mazieres
   * <dm at lcs.mit.edu>.  For more information on the level of compatibility,
   * please refer to the comments in BF_set_key() below and to the included
   * crypt(3) man page.
   *
   * 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).
