	↳	com.sun.crypto.provider.DHKeyPairGenerator

Class Overview

This class represents the key pair generator for Diffie-Hellman key pairs.

This key pair generator may be initialized in two different ways:

By providing the size in bits of the prime modulus - This will be used to create a prime modulus and base generator, which will then be used to create the Diffie-Hellman key pair. The default size of the prime modulus is 1024 bits.
By providing a prime modulus and base generator

Inherited Methods

From class java.security.KeyPairGeneratorSpi

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Constructors

public DHKeyPairGenerator ()

Public Methods

public KeyPair generateKeyPair ()

Generates a key pair.

Returns

the new key pair

public void initialize (AlgorithmParameterSpec algParams, SecureRandom random)

Initializes this key pair generator for the specified parameter set and source of randomness.

The given parameter set contains the prime modulus, the base generator, and optionally the requested size in bits of the random exponent (private value).

Parameters

algParams	the parameter set used to generate the keys.
random	the source of randomness

Throws

InvalidAlgorithmParameterException	if the given parameters are inappropriate for this key pair generator

public void initialize (int keysize, SecureRandom random)

Initializes this key pair generator for a certain keysize and source of randomness. The keysize is specified as the size in bits of the prime modulus.

Parameters

keysize	the keysize (size of prime modulus) in bits
random	the source of randomness
