AlgorithmParameterGeneratorSpi

public AlgorithmParameterGeneratorSpi()

Constructs a new AlgorithmParameterGeneratorSpi

Method Detail

engineInit

protected abstract void engineInit(int size,
              SecureRandom random)

Initializes the parameter generator with the specified size and SecureRandom

Parameters:

size - the size( in number of bits)

random - the SecureRandom class to use for randomness

engineInit

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

Initializes the parameter generator with the specified AlgorithmParameterSpec and SecureRandom classes. If genParamSpec is an invalid AlgorithmParameterSpec for this AlgorithmParameterGeneratorSpi then it throws InvalidAlgorithmParameterException

Parameters:

genParamSpec - the AlgorithmParameterSpec class to use

random - the SecureRandom class to use for randomness

Throws:

InvalidAlgorithmParameterException - genParamSpec is invalid

engineGenerateParameters

protected abstract AlgorithmParameters engineGenerateParameters()

Generate a new set of AlgorithmParameters.
