         *      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.
