	AlgorithmParameterGeneratorSpi() Constructs a new AlgorithmParameterGeneratorSpi

Method Summary
protected abstract AlgorithmParameters	engineGenerateParameters() Generate a new set of AlgorithmParameters.
protected abstract void	engineInit(int size, SecureRandom random) Initializes the parameter generator with the specified size and SecureRandom
protected abstract void	engineInit(AlgorithmParameterSpec genParamSpec, SecureRandom random) Initializes the parameter generator with the specified AlgorithmParameterSpec and SecureRandom classes.

Constructor Detail

AlgorithmParameterGeneratorSpi

public AlgorithmParameterGeneratorSpi()

Constructs a new AlgorithmParameterGeneratorSpi

Method Detail

engineGenerateParameters

protected abstract AlgorithmParameters engineGenerateParameters()

Generate a new set of AlgorithmParameters.

UNKNOWN: a new set of algorithm parameters

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)

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
