  37  *  Description:
  38  *      This is the header file for code which implements the Secure
  39  *      Hashing Algorithm 1 as defined in FIPS PUB 180-1 published
  40  *      April 17, 1995.
  41  *
  42  *      Many of the variable names in this code, especially the
  43  *      single character names, were used because those were the names
  44  *      used in the publication.
  45  *
  46  *      Please read the file sha1.c for more information.
