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.
