通过网络加密字符串#

程序运行得很好,但我需要对它进行加密,这就是问题所在,当我使用加密时,它似乎在每次发送数据后都会关闭连接,我需要重新运行它以接收更多的消息(我不能这样做,因为它在聊天,而且应该是连续的)

顺便说一下,我不介意,即使它是一个弱加密,只要它不是纯文本是好的。

这是我的程序(服务器)的一个方面:

public static void Main()
   {
      string data;
      IPEndPoint ip = new IPEndPoint(IPAddress.Any, 9999);

      Socket socket = new Socket(AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp);

      socket.Bind(ip);
      socket.Listen(10);

      Socket client = socket.Accept();
      IPEndPoint newclient = (IPEndPoint)client.RemoteEndPoint;
      Console.WriteLine("Connected with {0} at port {1}",newclient.Address, newclient.Port);

      NetworkStream ns = new NetworkStream(client);
      StreamReader sr = new StreamReader(ns);
      StreamWriter sw = new StreamWriter(ns);

      string welcome = "Welcome";
      sw.WriteLine(welcome);
      sw.Flush();

      while(true)
      {
         data = sr.ReadLine();
         Console.WriteLine(data);
         sw.WriteLine(data);
         sw.Flush();
      }
      Console.WriteLine("Disconnected from {0}", newclient.Address);
      sw.Close();
      sr.Close();
      ns.Close(); 
   }

下面是我尝试用于加密的代码示例:(server) IPAddress IP2=IPAddress.Parse(IP); TcpListener TCPListen=新TcpListener(IP2,端口);

                TCPListen.Start();

            TcpClient TCP = TCPListen.AcceptTcpClient();


            NetworkStream NetStream = TCP.GetStream();




            RijndaelManaged RMCrypto = new RijndaelManaged();


            byte[] Key = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16 };
            byte[] IV = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16 };




            CryptoStream CryptStream = new CryptoStream(NetStream,
               RMCrypto.CreateDecryptor(Key, IV),
               CryptoStreamMode.Read);

            StreamReader SReader = new StreamReader(CryptStream);




            message = SReader.ReadToEnd();

            textBox3.Clear();

            textBox3.Text = message;

            CryptStream.Flush();

            SReader.Close();







            NetStream.Flush();

            NetStream.Close();

            TCPListen.Stop();
            TCP.Close();
