Constructor Details

AlgorithmParameterGeneratorSpi

public AlgorithmParameterGeneratorSpi()
Constructs a new AlgorithmParameterGeneratorSpi

Method Details

engineGenerateParameters

protected abstract AlgorithmParameters engineGenerateParameters()
Generate a new set of AlgorithmParameters.

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
