Class DHGenParameterSpec

java.lang.Object
  javax.crypto.spec.DHGenParameterSpec

All Implemented Interfaces:

AlgorithmParameterSpec

public class DHGenParameterSpec
extends Object
implements AlgorithmParameterSpec

Disabled: no SafeJ information.

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.

Constructor Detail

DHGenParameterSpec

public DHGenParameterSpec(int primeSize,
                          int exponentSize)

Class is disabled.

Constructs a parameter set for the generation of Diffie-Hellman (system) parameters. The constructed parameter set can be used to initialize an AlgorithmParameterGenerator object for the generation of Diffie-Hellman parameters.

Parameters:

primeSize - the size (in bits) of the prime modulus.

exponentSize - the size (in bits) of the random exponent.
