org.openeuler.sun.security.util.GMCurveDB

public class GMCurveDB
extends Object

Repository for well-known Elliptic Curve parameters. This class is a modified version of the CurveDB class in the Sun library, with the main difference being the addition of two sets of standard elliptic curve parameters for the SM2 algorithm.
