  /*
   * This code implements the MD4 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.
   * Todd C. Miller modified the MD5 code to do MD4 based on RFC 1186.
   *
   * 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.
