public KeyPair generateKeyPair()

Overrides java.security.KeyPairGenerator.generateKeyPair.

Doc from java.security.KeyPairGenerator.generateKeyPair.

Generates a key pair.

If this KeyPairGenerator has not been initialized explicitly, provider-specific defaults will be used for the size and other (algorithm-specific) values of the generated keys.

This will generate a new key pair every time it is called.

This method is functionally equivalent to genKeyPair.

Returns:KeyPair

the generated key pair

public void initialize(int keysize, SecureRandom random)

Overrides java.security.KeyPairGenerator.initialize.

Doc from java.security.KeyPairGenerator.initialize.

Initializes the key pair generator for a certain keysize with the given source of randomness (and a default parameter set).

Parameters
keysize:int

the keysize. This is an algorithm-specific metric, such as modulus length, specified in number of bits.

random:SecureRandom

the source of randomness.

public void initialize(AlgorithmParameterSpec param, SecureRandom random) throws InvalidAlgorithmParameterException

Overrides java.security.KeyPairGenerator.initialize.

Doc from java.security.KeyPairGenerator.initialize.

Initializes the key pair generator with the given parameter set and source of randomness.

This concrete method has been added to this previously-defined abstract class. This method calls the KeyPairGeneratorSpi initialize method, passing it params and random. That initialize method always throws an UnsupportedOperationException if it is not overridden by the provider.

Parameters
param:AlgorithmParameterSpec

the parameter set used to generate the keys.

random:SecureRandom

the source of randomness.

Annotations
@Override
Exceptions
InvalidAlgorithmParameterException:
if the given parameters are inappropriate for this key pair generator.
