Constructor Detail

DSAKeyParametersGenerationParameters

public DSAKeyParametersGenerationParameters()

Parameters for FIPS186.2 using a default strength of 20, and a certainty of 20.

DSAKeyParametersGenerationParameters

public DSAKeyParametersGenerationParameters(int lsize)

Parameters for FIPS186.2 using a default certainty of 20.

Parameters:

lsize - size of the P prime number (the key strength) in bytes.

DSAKeyParametersGenerationParameters

public DSAKeyParametersGenerationParameters(int lsize,
                                            int certainty)

Parameters for FIPS186.2.

Parameters:

lsize - size of the P prime number (the key strength) in bytes.

certainty - certainty for prime evaluation.
