sha1.h File Reference

Detailed 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.
