Constructor Detail

NaccacheSternKeyGenerationParameters

public NaccacheSternKeyGenerationParameters(java.security.SecureRandom random,
                                            int strength,
                                            int certainty,
                                            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

NaccacheSternKeyGenerationParameters

public NaccacheSternKeyGenerationParameters(java.security.SecureRandom random,
                                            int strength,
                                            int certainty,
                                            int cntSmallPrimes,
                                            boolean debug)

Parameters for 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

debug - Turn debugging on or off (reveals secret information, use with caution)
