Method Summary

Modifier and TypeMethod and Description
public KeyPair
generateKeyPair()

Implements abstract java.security.KeyPairGeneratorSpi.generateKeyPair.

Generates a key pair.

private KeyPair

Returns:

A composite KeyPair
getCompositeKeyPair()

Generates a KeyPair of CompositePublicKey and CompositePrivateKey.

public void
initialize(int keySize, SecureRandom random)

Implements abstract java.security.KeyPairGeneratorSpi.initialize.

Native public method.

public void
initialize(AlgorithmParameterSpec
Unsupported, needs to be null.
paramSpec, SecureRandom
A SecureRandom used by component key generators.
secureRandom)

Overrides java.security.KeyPairGeneratorSpi.initialize.

Setting custom AlgorithmParameterSpec is not supported since the composite signature algorithm definition allow only for one specific parameter spec which is initialized by the initializeParameters method.
