/*
 * RIPEMD-160 is a 160-bit cryptographic hash function, designed by Hans
 * Dobbertin, Antoon Bosselaers, and Bart Preneel. It is intended to be
 * used as a secure replacement for the 128-bit hash functions MD4, MD5,
 * and RIPEMD
 * See also: http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html
 *
 * RIPEMD-128 is a plug-in substitute for RIPEMD (or MD4 and MD5, for
 * that matter) with a 128-bit result. 128-bit hash results do not
 * offer sufficient protection for the next ten years, and
 * applications using 128-bit hash functions should consider upgrading
 * to a 160-bit hash function.
 *
 * RIPEMD-256 and RIPEMD-320 are optional extensions of, respectively,
 * RIPEMD-128 and RIPEMD-160, and are intended for applications of
 * hash functions that require a longer hash result without needing a
 * larger security level.
 */

/* Implementation of the RIPE-MD Hash Algorithms.
 * Based on the SHA-1 implementation, (C) by A.M. Kuchling
 *
 * The ripemd160 code was written by Nikos Mavroyanopoulos, the code
 * for ripemd128, ripemd256 and ripemd320 was added by B. Poettering
 * in April 2004.
