SM2 sm02 = new SM2();
SM2KeyPair keyPair = sm02.generateKeyPair();
ECPoint publicKey2=keyPair.getPublicKey();
BigInteger privateKey2=keyPair.getPrivateKey();
sm02.exportPublicKey(publicKey2, "E:/publickey.pem");
sm02.exportPrivateKey(privateKey2, "E:/privatekey.pem");
ECPoint publicKey3 = sm02.importPublicKey("E:/publickey.pem");
BigInteger privateKey3 = sm02.importPrivateKey("E:/privatekey.pem");
