Method Details

engineGenerateParameters

protected AlgorithmParameters engineGenerateParameters()

Generates the parameters.

Specified by:

engineGenerateParameters in class AlgorithmParameterGeneratorSpi

Returns:

the new AlgorithmParameters object.

engineInit

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

Initializes this parameter generator with a set of algorithm-specific parameter generation values.

Specified by:

engineInit in class AlgorithmParameterGeneratorSpi

Parameters:

genParamSpec - the set of algorithm-specific parameter generation values.

random - the source of randomness.

Throws:

InvalidAlgorithmParameterException - if the given parameter generation values are inappropriate for this parameter generator.

engineInit
