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.
