使用CryptoStream读取和写入TCP套接字
本文关键字:TCP 套接字 CryptoStream 读取 使用 | 更新日期: 2023-09-27 17:57:33
我正在尝试加密通过TCP连接发送的数据,但是,我没有通过CryptoStream
接收到任何数据。
这是我设置流的类:
public class SecureCommunication
{
public SecureCommunication(TcpClient client, byte[] key, byte[] iv)
{
_client = client;
_netStream = _client.GetStream();
var rijndael = new RijndaelManaged();
_cryptoReader = new CryptoStream(_netStream,
rijndael.CreateEncryptor(key, iv), CryptoStreamMode.Read);
_cryptoWriter = new CryptoStream(_netStream,
rijndael.CreateEncryptor(key, iv), CryptoStreamMode.Write);
_reader = new StreamReader(_cryptoReader);
_writer = new StreamWriter(_cryptoWriter);
}
public string Receive()
{
return _reader.ReadLine();
}
public void Send(string buffer)
{
_writer.WriteLine(buffer);
_writer.Flush();
}
...
密钥和初始化矢量:
byte[] iv = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16 };
byte[] key = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16 };
在我的测试客户端程序中,我称之为
var client = new TcpClient("xxx.xxx.xxx.xxx", 12345);
var communication = new SecureTcpCommunication(client, key, iv);
communication.Send("Test message");
在我的服务器上,我打电话给:
var serverSocket = new TcpListener(IPAddress.Any, tcpPort);
var client = serverSocket.AcceptTcpClient();
var communication = new SecureTcpCommunication(client, key, iv);
Console.WriteLine($"Received message: {communication.Receive()}");
然而,应用程序在communication.Receive
上阻塞,并且永远不会结束。我在这里做错了什么?我觉得这很简单。。
在send函数中,最后调用_cryptoWriter.Flush()
。_writer.Flush()
不对封装流调用flush。
