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. | |
