Method Detail

engineGenerateParameters

protected java.security.AlgorithmParameters engineGenerateParameters()

Generates the parameters.

Specified by:

engineGenerateParameters in class java.security.AlgorithmParameterGeneratorSpi

Returns:

the new AlgorithmParameters object.

engineInit

protected void engineInit(java.security.spec.AlgorithmParameterSpec genParamSpec,
                          java.security.SecureRandom random)
                   throws java.security.InvalidAlgorithmParameterException

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

Specified by:

engineInit in class java.security.AlgorithmParameterGeneratorSpi

Parameters:

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

random - the source of randomness.

Throws:

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

engineInit

protected void engineInit(int size,
                          java.security.SecureRandom random)

Initializes the receiver with the specified parameter size and source of randomness.

Specified by:

engineInit in class java.security.AlgorithmParameterGeneratorSpi

Parameters:

size - the strength (size of prime) in bits.

random - the source of randomness.
