我尝试加密通过TCP连接发送的数据，但是，我没有通过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();
}
...
收到任何数据。
以下是我设置流的类：
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 };
密钥和初始向量：
var client = new TcpClient("xxx.xxx.xxx.xxx", 12345);
var communication = new SecureTcpCommunication(client, key, iv);
communication.Send("Test message");
在我的测试客户端程序中，我打电话
var serverSocket = new TcpListener(IPAddress.Any, tcpPort);
var client = serverSocket.AcceptTcpClient();
var communication = new SecureTcpCommunication(client, key, iv);
Console.WriteLine($"Received message: {communication.Receive()}");
在我的服务器上，我打电话给：
communication.Receive然而，应用程序阻止doSomething并且永远不会完成。我在这做错了什么？我觉得它很简单......
答案 0 :(得分：0)
在发送功能中，最后拨打_cryptoWriter.Flush()。 _writer.Flush()不会在封装的流上调用flush。
