+ *      This is the header file for code which implements the Secure
+ *      Hashing Algorithm 1 as defined in FIPS PUB 180-1 published
+ *      April 17, 1995.
+ *
+ *      Many of the variable names in this code, 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.
