00005  * This is the header file for the MD5 message-digest algorithm.
00006  * The algorithm is due to Ron Rivest.  This code was
00007  * written by Colin Plumb in 1993, no copyright is claimed.
00008  * This code is in the public domain; do with it what you wish.
00009  *
00010  * Equivalent code is available from RSA Data Security, Inc.
00011  * This code has been tested against that, and is equivalent,
00012  * except that you don't need to include two pages of legalese
00013  * with every copy.
00014  *
00015  * To compute the message digest of a chunk of bytes, declare an
00016  * MD5Context structure, pass it to MD5Init, call MD5Update as
00017  * needed on buffers full of bytes, and then call MD5Final, which
00018  * will fill a supplied 16-byte array with the digest.
00019  *
00020  * Changed so as no longer to depend on Colin Plumb's `usual.h'
00021  * header definitions; now uses stuff from dpkg's config.h
00022  *  - Ian Jackson <ijackson@nyx.cs.du.edu>.
00023  * Still in the public domain.
00024  *
00025  * Josh Coalson: made some changes to integrate with libFLAC.
00026  * Still in the public domain, with no warranty.
