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");
