flatbird 0:a816c25e83ed 8 * Description:
flatbird 0:a816c25e83ed 9 * This is the header file for code which implements the Secure
flatbird 0:a816c25e83ed 10 * Hashing Algorithm 1 as defined in FIPS PUB 180-1 published
flatbird 0:a816c25e83ed 11 * April 17, 1995.
flatbird 0:a816c25e83ed 12 *
flatbird 0:a816c25e83ed 13 * Many of the variable names in this code, especially the
flatbird 0:a816c25e83ed 14 * single character names, were used because those were the names
flatbird 0:a816c25e83ed 15 * used in the publication.
flatbird 0:a816c25e83ed 16 *
flatbird 0:a816c25e83ed 17 * Please read the file sha1.c for more information.
