## cryptix.provider.elgamal
Class DefaultElGamalParameterSet

public class DefaultElGamalParameterSet
extends GenericElGamalParameterSet

A default set of ElGamal parameters for Cryptix. These parameters may change in future versions of Cryptix, and longer primes will be added.

The best methods for computing discrete logarithms in GF(p) have an expensive pre-computation stage, but once the pre-computation has been done, individual logarithms can be calculated quickly. In order to make sure that a particular set of parameters does not become too much of a target because it is used in more than one application, you may wish to generate your own set of parameters.
