DSAParameterGenerationParameters

public DSAParameterGenerationParameters(int L,
 int N,
 int certainty,
 SecureRandom random)

Construct without a usage index, this will do a random construction of G.

Parameters:

L - desired length of prime P in bits (the effective key size).

N - desired length of prime Q in bits.

certainty - certainty level for prime number generation.

random - the source of randomness to use.
