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.

DHGenParameterSpec
public DHGenParameterSpec(int primeSize, int exponentSize)
Constructs a parameter set for the generation of Diffie-Hellman (system) parameters. The constructed parameter set can be used to initialize anAlgorithmParameterGenerator
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.
