      *  Description:
      *      This class implements the Secure Hashing Standard as defined
      *      in FIPS PUB 180-1 published April 17, 1995.
      *
      *      Many of the variable names in the SHA1Context, especially the
      *      single character names, were used because those were the names
      *      used in the publication.
      *
      *      Please read the file sha1.c for more information.
