Member Function Documentation

bool DSA::GeneratePrimes	(	const byte *	seed,
		unsigned int	seedLength,
		int &	counter,
		Integer &	p,
		unsigned int	primeLength,
		Integer &	q,
		bool	useInputCounterValue = false
	)			[static]

Generate DSA primes according to NIST standard.

Both seedLength and primeLength are in bits, but seedLength should be a multiple of 8. If useInputCounterValue == true, the counter parameter is taken as input, otherwise it's used for output
