  10  *  Description:
  11  *      This is the header file for code which implements the Secure
  12  *      Hashing Algorithm 1 as defined in FIPS PUB 180-1 published
  13  *      April 17, 1995.
  14  *
  15  *      Many of the variable names in this code, especially the
  16  *      single character names, were used because those were the names
  17  *      used in the publication.
  18  *
  19  *      Please read the file sha1.c for more information.
