| 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. |
