                                            int strength,

                                            int cntSmallPrimes)
        Parameters for generating a NaccacheStern KeyPair.
        Parameters:
        random - The source of randomness
        strength - The desired strength of the Key in Bits
        certainty - the probability that the generated primes are not really prime as integer: 2^(-certainty) is then the probability
        cntSmallPrimes - How many small key factors are desired
