2 * Written by Daniel Richards <[email protected]> 6/7/2002
3 * hash.c: This app uses libtomcrypt to hash either stdin or a file
4 * This file is Public Domain. No rights are reserved.
5 * Compile with 'gcc hashsum.c -o hashsum -ltomcrypt'
6 * This example isn't really big enough to warrent splitting into
7 * more functions ;)
