public final class RIPEMD320

extends MDFamilyDigest

This class implements the RIPEMD-320 message digest algorithm according to the Handbook of Applied Cryptography, Menezes, van Oorschot, Vanstone, CRC Press, 1997, algorithm 9.55

The algorithm has been invented by Hans Dobbertin, and further information concerning the RIPEMD message digest family can be found at www.esat.kuleuven.ac.be/~bosselae/ripemd320.html.
