Contents

    • Constructor Detail

      • ECParameterSpec

        public ECParameterSpec(EllipticCurve curve,
               ECPoint g,
               BigInteger n,
               int h)
        Creates elliptic curve domain parameters based on the specified values.
        Parameters:
        curve - the elliptic curve which this parameter defines.
        g - the generator which is also known as the base point.
        n - the order of the generator g.
        h - the cofactor.
        Throws:
        NullPointerException - if curve, g, or n is null.
        IllegalArgumentException - if n or h is not positive.
