Method Detail

engineInit

protected abstract void engineInit(int size,
                                   SecureRandom random)

Initializes this AlgorithmParameterGeneratorSpi with the given size and the given SecureRandom. The default parameter set will be used.

Parameters:

size - the size (in number of bits).

random - the source of randomness.

engineInit

protected abstract void engineInit(AlgorithmParameterSpec genParamSpec,
                                   SecureRandom random)
                            throws InvalidAlgorithmParameterException

Initializes this AlgorithmParameterGeneratorSpi with the given AlgorithmParameterSpec and the given SecureRandom.

Parameters:

genParamSpec - the parameters to use.

random - the source of randomness.

Throws:

InvalidAlgorithmParameterException - if the specified parameters are not supported.

engineGenerateParameters

protected abstract AlgorithmParameters engineGenerateParameters()

Computes and returns AlgorithmParameters for this generator's algorithm.

Returns:

AlgorithmParameters for this generator's algorithm.
