Class DHGenParameterSpec

All Implemented Interfaces:
AlgorithmParameterSpec
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.

Constructors

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 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.

Methods

getPrimeSize

public int getPrimeSize()

Returns the size in bits of the prime modulus.

Returns:
the size in bits of the prime modulus

getExponentSize

public int getExponentSize()

Returns the size in bits of the random exponent (private value).

Returns:
the size in bits of the random exponent (private value)
