Class Overview
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.

Public Constructors
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. |
Public Methods
public int getExponentSize ()

Returns
- the size in bits of the random exponent (private value)
public int getPrimeSize ()
Returns the size in bits of the prime modulus.
Returns
- the size in bits of the prime modulus
