Method Summary

Modifier and Type	Method and Description
java.security.KeyPair	generateKeyPair()
void	initialize(java.security.spec.AlgorithmParameterSpec paramSpec, java.security.SecureRandom secureRandom) 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.
void	initialize(int keySize, java.security.SecureRandom random) Native public method.

Method Detail

initialize

public void initialize(int keySize,
                       java.security.SecureRandom random)

Native public method. There is no notion of a keysize for composite signatures. Therefore, this method is unsupported. For setting a custom SecureRandom the other initialize method must be used.

Specified by:

initialize in class java.security.KeyPairGeneratorSpi

Parameters:

keySize -

random -

initialize

public void initialize(java.security.spec.AlgorithmParameterSpec paramSpec,
                       java.security.SecureRandom secureRandom)
                throws java.security.InvalidAlgorithmParameterException

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. This method only serves to set a custom SecureRandom.

Overrides:

initialize in class java.security.KeyPairGeneratorSpi

Parameters:

paramSpec - Unsupported, needs to be null.

secureRandom - A SecureRandom used by component key generators.

Throws:

java.security.InvalidAlgorithmParameterException

generateKeyPair

public java.security.KeyPair generateKeyPair()

Specified by:

generateKeyPair in class java.security.KeyPairGeneratorSpi
