   8  * This code implements the MD5 message-digest algorithm.
   9  * The algorithm is due to Ron Rivest.  This code was
  10  * written by Colin Plumb in 1993, no copyright is claimed.
  11  * This code is in the public domain; do with it what you wish.
  12  *
  13  * Equivalent code is available from RSA Data Security, Inc.
  14  * This code has been tested against that, and is equivalent,
  15  * except that you don't need to include two pages of legalese
  16  * with every copy.
  17  *
  18  * To compute the message digest of a chunk of bytes, declare an
  19  * MD5Context structure, pass it to MD5Init, call MD5Update as
  20  * needed on buffers full of bytes, and then call MD5Final, which
  21  * will fill a supplied 16-byte array with the digest.
