Method Detail

init

public void init(int size,
                 int certainty,
                 SecureRandom random)

initialise the key generator.

Parameters:

size - size of the key (range 2^512 -> 2^1024 - 64 bit increments)

certainty - measure of robustness of prime (for FIPS 186-2 compliance this should be at least 80).

random - random byte source.

generateParameters

public DSAParameters generateParameters()

which generates the p and g values from the given parameters, returning the DSAParameters object.
