   +----javax.crypto.spec.DHGenParameterSpec

public class DHGenParameterSpec
extends Object
implements AlgorithmParameterSpec
This class specifies the set of parameters used for generating Diffie-Hellman (system) parameters for use in Diffie-Hellman key agreement. This is typically done by a central authority.

The central authority, after computing the parameters, must send this information to the parties looking to agree on a secret key.
