public class ElGamalGenParameterSpec
extends java.lang.Object
implements java.security.spec.AlgorithmParameterSpec

ElGamal generation parameter specification.

This class represents a ElGamal generation parameter specification to be used by a central authority for generating ElGamal parameters, which subsequently are sent to the entities involved in the key agreement procedure.

This class specifies the ElGamal generation parameters length of the prime modulus and length of the exponent (private value).
