请问pb2019的json发送数据时,对方需要对发送的json数据进行带 key  的加密,他们的加密方式例子大致见下面:

///////////////////////////////

加密示例代码

String param = AesUtils.encrypt(参数json字符串, KEY);

​ 解密示例代码

String decrypSre = AesUtils.decryptToken(param, KEY));

​ 加密工具类代码

public class AesUtils {

    private static final Log log = Log.get();
    private static final String ALGORITHM = "AES";

    public static void main(String[] args) {
        String cltk = "{\n" +
                "    \"vesselName\": \"xxx\",\n" +
                "    \"voyage\": \"xxx\"\n" +
                "}";
        String key = "JJ2CQ_903DAAAE7A8387E7379684BC013085CC";
        String encrypt = encrypt(cltk, key);
        log.info("加密后:" + encrypt.length() + " " + encrypt);
        String decryptToken = decryptToken(encrypt, key);
        log.info("解密后:" + decryptToken);
    }

    /**
     * 加密
     */
    public static String encrypt(String str, String password) {
        try {
            byte[] enCodeFormat = getSecretKey(password);
            SecretKeySpec key = new SecretKeySpec(enCodeFormat, "AES");
            // 创建密码器
            Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
            byte[] byteContent = str.getBytes("UTF-8");
            // 初始化
            cipher.init(Cipher.ENCRYPT_MODE, key);
            byte[] result = cipher.doFinal(byteContent);
            // 加密
            return Base64.encode(result);
        } catch (Exception e) {
            log.error("encrypt password failed, ", e);
        }
        return null;
    }


    /**
     * 加密,去除特殊字符
     */
    public static String encryptExcludeSpecialChars(String str, String password) {
        try {
            byte[] enCodeFormat = getSecretKey(password);
            SecretKeySpec key = new SecretKeySpec(enCodeFormat, "AES");
            // 创建密码器
            Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
            byte[] byteContent = str.getBytes("UTF-8");
            // 初始化
            cipher.init(Cipher.ENCRYPT_MODE, key);
            byte[] result = cipher.doFinal(byteContent);
            return new String(result);
        } catch (Exception e) {
            log.error("encrypt password failed, ", e);
        }
        return null;
    }

    /**
     * 解密
     */
    public static String decryptToken(String str, String password) {
        log.info("解密密文:{},秘钥:{}", str, password);
        // 长token解密得到明文token
        String realToken = "";
        try {
            realToken = decryptEcb(str, password);
        } catch (Exception e) {
            log.error("decrypt password failed, ", e);
        }
        log.info("解密明文:{}", realToken);
        return realToken;
    }

    /**
     * 解密,没有特殊字符情况下
     */
    public static String decryptExcludeSpecialChars(String str, String password) {
        log.info("解密密文:{},秘钥:{}", str, password);
        String decryptStr = "";
        try {
            decryptStr = decryptEcbExcludeSpecialChars(str, password);
        } catch (Exception e) {
            log.error("decrypt password failed, ", e);
        }
        log.info("解密明文:{}", decryptStr);
        return decryptStr;
    }

    private static String decryptEcb(String data, String key) throws Exception {
        if (ObjectUtil.isEmpty(key) || key.length() < 16) {
            return null;
        }
        byte[] decryptdata = Base64.decode(data);
        byte[] skey = getSecretKey(key);
        // 解密
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
        cipher.init(Cipher.DECRYPT_MODE, toKey(skey));
        byte[] result = cipher.doFinal(decryptdata);
        return new String(result);
    }

    private static String decryptEcbExcludeSpecialChars(String data, String key) throws Exception {
        if (ObjectUtil.isEmpty(key) || key.length() < 16) {
            return null;
        }
        byte[] decryptdata = data.getBytes("UTF-8");
        byte[] skey = getSecretKey(key);
        // 解密
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
        cipher.init(Cipher.DECRYPT_MODE, toKey(skey));
        byte[] result = cipher.doFinal(decryptdata);

        // 转化为字符串
        return new String(result);
    }
    private static byte[] getSecretKey(String key) throws UnsupportedEncodingException {
        return key.substring(0, 16).getBytes("UTF-8");
    }
    private static Key toKey(byte[] key) throws IllegalArgumentException {
        return new SecretKeySpec(key, ALGORITHM);
    }
/////////////////

请问下,那我们pb 在发送json数据过去 也要进行 key 方式加密,那pb 怎样处理呢? 能给个例子吗?
谢谢
