static BigInteger Primes::createProbablePrime	(	int	bitLength,
		int	certainty,
		const int *	randomSeeds = `0`,
		int	numRandomSeeds = `0`
	)

static

Creates a random prime number with a given bit-length.

The certainty parameter specifies how many iterations to use when testing for primality. A safe value might be anything over about 20-30.

The randomSeeds parameter lets you optionally pass it a set of values with which to seed the random number generation, improving the security of the keys generated.

static bool Primes::isProbablyPrime	(	const BigInteger &	number,
		int	certainty
	)

static

Tests a number to see if it's prime.

This isn't a bulletproof test, it uses a Miller-Rabin test to determine whether the number is prime.

The certainty parameter specifies how many iterations to use when testing - a safe value might be anything over about 20-30.
