Method Summary

protected Object

clone()

We override clone here to make it accessible for use by DummyKeyPairGenerator.

abstract KeyPair

generateKeyPair()

Generates a KeyPair according the rules for the algorithm.

abstract void

initialize(int keysize, SecureRandom random)

Initialize the KeyPairGeneratorSpi with the specified key size and source of randomness

void

initialize(AlgorithmParameterSpec params, SecureRandom random)

Method Detail

protected Object clone()

We override clone here to make it accessible for use by DummyKeyPairGenerator.

public abstract KeyPair generateKeyPair()

Generates a KeyPair according the rules for the algorithm. Unless intialized, algorithm defaults will be used. It creates a unique key pair each time.

Returns: a key pair

initialize

public abstract void initialize(int keysize, SecureRandom random)

Initialize the KeyPairGeneratorSpi with the specified key size and source of randomness

Parameters: keysize size of the key to generate random A SecureRandom source of randomness

initialize

Initialize the KeyPairGeneratorSpi with the specified AlgorithmParameterSpec and source of randomness This is a concrete method. It may be overridden by the provider and if the AlgorithmParameterSpec class is invalid throw InvalidAlgorithmParameterException. By default this method just throws UnsupportedOperationException.

Parameters: params A AlgorithmParameterSpec to intialize with random A SecureRandom source of randomness

Throws: InvalidAlgorithmParameterException
