   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.
