   3  * This code implements the MD5 message-digest algorithm.
   4  * The algorithm is due to Ron Rivest.  This code was
   5  * written by Colin Plumb in 1993, no copyright is claimed.
   6  * This code is in the public domain; do with it what you wish.
   7  *
   8  * Equivalent code is available from RSA Data Security, Inc.
   9  * This code has been tested against that, and is equivalent,
  10  * except that you don't need to include two pages of legalese
  11  * with every copy.
  12  *
  13  * To compute the message digest of a chunk of bytes, declare an
  14  * MD5Context structure, pass it to rpmMD5Init, call rpmMD5Update as
  15  * needed on buffers full of bytes, and then call rpmMD5Final, which
  16  * will fill a supplied 16-byte array with the digest.
