public class DHAgreement
extends java.lang.Object
note: This uses MTI/A0 key agreement in order to make the key agreement secure against passive attacks. If you're doing Diffie-Hellman and both parties have long term public keys you should look at using this. For further information have a look at RFC 2631.
It's possible to extend this to more than two parties as well, for the moment that is left as an exercise for the reader.
