All Implemented Interfaces:

AsymmetricCipherKeyPairGenerator

public class DHKeyPairGenerator
extends java.lang.Object
implements AsymmetricCipherKeyPairGenerator

a Diffie-Helman key pair generator. This generates keys consistent for use in the MTI/A0 key agreement protocol as described in "Handbook of Applied Cryptography", Pages 516-519.
