基于java 使用FishermanJCE配合加密卡进行SM2加密的代码示例

以下是基于Java使用FishermanJCE配合加密卡进行SM2加密的代码示例：

import java.security.*;
import java.util.Arrays;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
import com.feinno.security.sm.SM2PublicKey;
import com.feinno.security.sm.SM2PrivateKey;
import com.feinno.security.sm.SM2Engine;
import com.feinno.security.sm.SM2Cipher;
import com.feinno.security.sm.SM2Util;
import com.feinno.security.sm.SM2Constants;
import com.feinno.security.sm.SM2KeyPairGenerator;
import com.feinno.security.sm.SM2KeyPair;
import com.feinno.security.sm.SM2KeyExchange;

public class SM2EncryptWithFishermanJCE {
    public static void main(String[] args) throws Exception {
        // 添加BouncyCastleProvider支持
        Security.addProvider(new BouncyCastleProvider());

        // 生成SM2公私钥对
        SM2KeyPairGenerator generator = new SM2KeyPairGenerator();
        generator.initialize(SM2Constants.DEFAULT_CURVE, new SecureRandom());
        SM2KeyPair keyPair = generator.generateKeyPair();
        SM2PrivateKey privateKey = keyPair.getPrivateKey();
        SM2PublicKey publicKey = keyPair.getPublicKey();

        // 生成随机明文
        byte[] plaintext = new byte[256];
        new SecureRandom().nextBytes(plaintext);

        // 初始化SM2加密引擎
        SM2Engine engine = new SM2Engine();
        engine.init(SM2Engine.ENCRYPT_MODE, publicKey);

        // 使用FishermanJCE进行加密
        SM2Cipher cipher = new SM2Cipher();
        cipher.setCipherProviderName("FishermanJCE");
        cipher.setMode(SM2Cipher.MODE_C1C3C2);
        cipher.init(engine, privateKey, publicKey);
        byte[] ciphertext = cipher.doFinal(plaintext);

        // 初始化SM2解密引擎
        engine.init(SM2Engine.DECRYPT_MODE, privateKey);

        // 使用FishermanJCE进行解密
        cipher = new SM2Cipher();
        cipher.setCipherProviderName("FishermanJCE");
        cipher.setMode(SM2Cipher.MODE_C1C3C2);
        cipher.init(engine, privateKey, publicKey);
        byte[] decrypted = cipher.doFinal(ciphertext);

        // 验证解密结果是否与原始明文相同
        if (Arrays.equals(plaintext, decrypted)) {
            System.out.println("SM2 Encrypt with FishermanJCE success!");
        } else {
            System.out.println("SM2 Encrypt with FishermanJCE failed!");
        }
    }
}

注意，上面的代码示例仅供参考，实际运行需要根据自己的具体情况进行调整。另外，FishermanJCE是一款商业加密软件，需要进行购买和授权才能使用。
