public KeyPair generateKeyPair()

Implements abstract java.security.KeyPairGeneratorSpi.generateKeyPair.

Doc from java.security.KeyPairGeneratorSpi.generateKeyPair.

Generates a key pair. Unless an initialization method is called using a KeyPairGenerator interface, algorithm-specific defaults will be used. This will generate a new key pair every time it is called.

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

Overrides java.security.KeyPairGeneratorSpi.initialize.

Doc from java.security.KeyPairGeneratorSpi.initialize.

Initializes the key pair generator using the specified parameter set and user-provided source of randomness.

This concrete method has been added to this previously-defined abstract class. (For backwards compatibility, it cannot be abstract.) It may be overridden by a provider to initialize the key pair generator. Such an override is expected to throw an InvalidAlgorithmParameterException if a parameter is inappropriate for this key pair generator. If this method is not overridden, it always throws an UnsupportedOperationException.

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