bitLength - bitLength of the returned BigInteger. 
certainty - a measure of the uncertainty that the caller is willing to tolerate. 
      The probability that the new BigInteger represents a prime number will 
      exceed (1 - 1/2certainty). The execution time of this constructor is 
      proportional to the value of this parameter. 

rnd - source of random bits used to select candidates to be tested for primality.
