public DualECPoints(int securityStrength, ECPoint p, ECPoint q, int cofactor)
The cofactor is used to calculate the output block length (maxOutlen) according to
max_outlen = largest multiple of 8 less than ((field size in bits) - (13 + log2(cofactor))
securityStrength
- maximum security strength to be associated with these parametersp
- the P point.q
- the Q point.cofactor
- cofactor associated with the domain parameters for the point generation.
