public interface InterKeyExClient
extends InterProtocolClient

This interface is implemented by classes for the client portion of an interactive key-exchange protocol.

In this context, the party which initiates the protocol is considered the client. Interactive means that the client may need to recieve information from the server, so the protocol can be used off-line.

An example of an interactive key-exchange protocol is the Diffie-Hellman protocol where each party must send the value g^a to the other before they can both calculate the key g^{ab}.
