| * This code implements the MD5 message-digest algorithm. |
| * The algorithm is due to Ron Rivest. This code was |
| * written by Colin Plumb in 1993, no copyright is claimed. |
| * This code is in the public domain; do with it what you wish. |
| * |
| * Equivalent code is available from RSA Data Security, Inc. |
| * This code has been tested against that, and is equivalent, |
| * except that you don't need to include two pages of legalese |
| * with every copy. |
| * |
| * To compute the message digest of a chunk of bytes, declare an |
| * MD5Context structure, pass it to MD5Init, call MD5Update as |
| * needed on buffers full of bytes, and then call MD5Final, which |
| * will fill a supplied 16-byte array with the digest. |
