Constructor and Description
DomainGenParameters(java.math.BigInteger p, java.math.BigInteger q) Construct from initial prime values, this will do a random construction of G.
DomainGenParameters(java.math.BigInteger p, java.math.BigInteger q, byte[] seed, int usageIndex) Construct for a specific usage index and initial prime values - this has the effect of using verifiable canonical generation of G.
DomainGenParameters(int strength) Construct just from strength (L) with a default value for N (160 for 1024, 256 for greater) and a default certainty.
DomainGenParameters(int strength, int certainty) Construct just from strength (L) with a default value for N (160 for 1024, 256 for greater).
DomainGenParameters(int L, int N, int certainty) Construct without a usage index, this will do a random construction of G.
DomainGenParameters(int L, int N, int certainty, int usageIndex) Construct for a specific usage index - this has the effect of using verifiable canonical generation of G.

Constructor Detail

DomainGenParameters

public DomainGenParameters(int strength)

Construct just from strength (L) with a default value for N (160 for 1024, 256 for greater) and a default certainty.

Parameters:

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

DomainGenParameters

public DomainGenParameters(int strength,
                           int certainty)

Construct just from strength (L) with a default value for N (160 for 1024, 256 for greater).

Parameters:

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

certainty - certainty level for prime number generation.
