* Description:
* 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.
