Method Detail

init

public void init(int size,
                 int certainty,
                 java.security.SecureRandom random)

Initialise the parameters generator.

Parameters:

size - bit length for the prime p

certainty - a measure of the uncertainty that the caller is willing to tolerate: the probability that the generated modulus is prime exceeds (1 - 1/2^certainty). The execution time of this method is proportional to the value of this parameter.

random - a source of randomness

generateParameters

public CramerShoupParameters generateParameters()

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

Note: can take a while[]

Returns:

a generated CramerShoupParameters object.
