5 * This is the header file for the MD5 message-digest algorithm.
6 * The algorithm is due to Ron Rivest.  This code was
7 * written by Colin Plumb in 1993, no copyright is claimed.
8 * This code is in the public domain; do with it what you wish.
9 *
10 * Equivalent code is available from RSA Data Security, Inc.
11 * This code has been tested against that, and is equivalent,
12 * except that you don't need to include two pages of legalese
13 * with every copy.
14 *
15 * To compute the message digest of a chunk of bytes, declare an
16 * MD5Context structure, pass it to MD5Init, call MD5Update as
17 * needed on buffers full of bytes, and then call MD5Final, which
18 * will fill a supplied 16-byte array with the digest.
19 *
20 * Changed so as no longer to depend on Colin Plumb's `usual.h'
21 * header definitions; now uses stuff from dpkg's config.h
22 *  - Ian Jackson <ijackson@nyx.cs.du.edu>.
23 * Still in the public domain.
24 *
25 * Josh Coalson: made some changes to integrate with libFLAC.
26 * Still in the public domain, with no warranty.
