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.
8: *
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
12: * with every copy.
