javax.crypto.spec
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.
Constructor Summary |
Constructs a parameter set for the generation of Diffie-Hellman
(system) parameters.
|
Method Summary |
int |
Returns the size in bits of the random exponent (private value).
|
int |
Returns the size in bits of the prime modulus.

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
{@link java.security.AlgorithmParameterGenerator 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.
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)
getPrimeSize
public int getPrimeSize()
-
Returns the size in bits of the prime modulus.
- Returns:
- the size in bits of the prime modulus
