                      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.
