4 * This code implements the MD5 message-digest algorithm.
5 * The algorithm is due to Ron Rivest. This code was
6 * written by Colin Plumb in 1993, no copyright is claimed.
7 * This code is in the public domain; do with it what you wish.
9 * Equivalent code is available from RSA Data Security, Inc.
10 * This code has been tested against that, and is equivalent,
11 * except that you don't need to include two pages of legalese
