    25   Independent implementation of MD5 (RFC 1321).
    26 
    27   This code implements the MD5 Algorithm defined in RFC 1321.
    28   It is derived directly from the text of the RFC and not from the
    29   reference implementation.

    31   The original and principal author of md5.h is L. Peter Deutsch
    32   <ghost@aladdin.com>.  Other authors are noted in the change history
    33   that follows (in reverse chronological order):
    34 
    35   2004-03-09 Jelmer Vernooij add G_MODULE_EXPORT for Bitlbee
    36   1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
    37   1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
    38         added conditionalization for C++ compilation from Martin
    39         Purschke <purschke@bnl.gov>.
    40   1999-05-03 lpd Original version.
     2 * MD5 hashing code copied from Lepton's crack <http://usuarios.lycos.es/reinob/>
     3 *
     4 * Adapted to be API-compatible with the previous (GPL-incompatible) code.

     8 * This code implements the MD5 message-digest algorithm.
     9 * The algorithm is due to Ron Rivest.  This code was
     10 * written by Colin Plumb in 1993, no copyright is claimed.
     11 * This code is in the public domain; do with it what you wish.
     12 *
     13 * Equivalent code is available from RSA Data Security, Inc.
     14 * This code has been tested against that, and is equivalent,
     15 * except that you don't need to include two pages of legalese
     16 * with every copy.
     17 *
     18 * To compute the message digest of a chunk of bytes, declare an
     19 * MD5Context structure, pass it to MD5Init, call MD5Update as
     20 * needed on buffers full of bytes, and then call MD5Final, which
     21 * will fill a supplied 16-byte array with the digest.
