dgriffin65 15:14382459c8b7 10 * April 17, 1995.
dgriffin65 15:14382459c8b7 11 *
dgriffin65 15:14382459c8b7 12 * Many of the variable names in this code, especially the
dgriffin65 15:14382459c8b7 13 * single character names, were used because those were the names
dgriffin65 15:14382459c8b7 14 * used in the publication.
dgriffin65 15:14382459c8b7 15 *
dgriffin65 15:14382459c8b7 16 * Please read the file sha1.c for more information.
