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