类 SM2KeyPairGenerator

java.lang.Object

java.security.KeyPairGeneratorSpi

org.openeuler.SM2KeyPairGenerator

public class SM2KeyPairGenerator
extends KeyPairGeneratorSpi

The difference between EC and SM key pair generation is that the elliptic curve is different. Refer to the key pair generation method of EC to implement the initialize(int, SecureRandom) method. Delegate the implementation of the two methods of initialize(AlgorithmParameterSpec, SecureRandom) and generateKeyPair to KeyPairGeneratorSpi.EC.
