我正在尝试在 C# 中编写一个加密函数，该函数生成一个可以在 Java 应用程序中解密的字符串。我从客户端收到的现有 Java 解密代码：

    public static String encryptParameters(byte plainText[], String sKey)
        throws RCPCipherException
    {
      Cipher cipher;
      DESedeKeySpec dks = new DESedeKeySpec(_getKeyBytes(sKey));
      java.security.Key secretKey = SecretKeyFactory.getInstance("DESede").generateSecret(dks);
      cipher = Cipher.getInstance("DESede/ECB/PKCS5Padding");
      cipher.init(1, secretKey);
      return Base64.encodeBase64URLSafeString(cipher.doFinal(plainText));
    }

到目前为止，我只在 C# 中有这个：

public string Encrypt(string toEncrypt, string encryptionKey, bool useHashing)
{
    byte[] keyArray;
    byte[] toEncryptArray = Encoding.UTF8.GetBytes(toEncrypt);

    if (useHashing)
    {
        var hashmd5 = new MD5CryptoServiceProvider();
        keyArray = hashmd5.ComputeHash(Encoding.UTF8.GetBytes(encryptionKey));
        hashmd5.Clear();
    }
    else
    {
        keyArray = Encoding.UTF8.GetBytes(encryptionKey);
    }

    var tripleDesCryptoServiceProvider = new TripleDESCryptoServiceProvider();

    //set the secret key for the tripleDES algorithm
    tripleDesCryptoServiceProvider.Key = keyArray;

    //mode of operation. there are other 4 modes.
    //We choose ECB(Electronic code Book)
    tripleDesCryptoServiceProvider.Mode = CipherMode.ECB;

    //padding mode(if any extra byte added)
    tripleDesCryptoServiceProvider.Padding = PaddingMode.PKCS7;

    var cTransform = tripleDesCryptoServiceProvider.CreateEncryptor();

    //transform the specified region of bytes array to resultArray
    var resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);

    //Release resources held by TripleDes Encryptor
    tripleDesCryptoServiceProvider.Clear();

    //Return the encrypted data into unreadable string format
    return Convert.ToBase64String(resultArray, 0, resultArray.Length);
}

可以做些什么来使它们兼容？

Java 函数中的纯文本字节数组参数是通过 String.getBytes("UTF-8") 创建的。
