所有已实现的接口:

Serializable

public class ECParameters
extends Object
implements Serializable

Specifications completely defining an elliptic curve. Used to define an elliptic curve by EllipticCurve, define(ECParamters ecp). NOTE: This is designed for an elliptic curve on the form: y^2 = x^3 + ax + b (mod p) with fixed generator and precomputed order. SECNamedCurves.getByName(String)
