Using SSL Stream with Asynchronous System.Net.Sockets - sockets

Question

My server is now running using Asynchronous System.Net.Sockets but i want to use SSL stream with it. i am pretty new to using SSL so here is my server code if someone can help me with it
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using System.Net.Sockets;
public class Wrapper
{
public byte[] buffer;
public Socket _socket;
public object connector;
}
public class WinSocket
{
private Dictionary<string, byte> Connections;
public event Action<Wrapper> AnnounceNewConnection;//Event Handlers
public event Action<Wrapper> AnnounceDisconnection;
public event Action<byte[], Wrapper> AnnounceReceive;
private Socket _socket;
public int MAX_USER_CONNECTIONS = 2;//Max User Connections
public WinSocket(ushort port)
{
try
{
Connections = new Dictionary<string, byte>();
_socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
_socket.Bind(new IPEndPoint(IPAddress.Any, port));
_socket.Listen(500);
_socket.BeginAccept(AcceptConnections, new Wrapper());
}
catch (Exception e)
{
Console.WriteLine(e);//write an exception
}
}
private void AcceptConnections(IAsyncResult result)
{
try
{
Wrapper wr = result.AsyncState as Wrapper;
wr._socket = _socket.EndAccept(result);
#region Invisible
string IP = wr._socket.RemoteEndPoint.ToString().Split(':')[0].ToString();//Get user ip
if (!Connections.ContainsKey(IP))
Connections.Add(IP, 1);
else
if (Connections[IP] <= MAX_USER_CONNECTIONS)//Maximum Connections Per IP
{
byte connections = Connections[IP];
Connections.Remove(IP);//Limit exceeded
Connections.Add(IP, (byte)(connections + 1));
}
else
{
wr._socket.Disconnect(false);
_socket.BeginAccept(AcceptConnections, new Wrapper());
return;
}
#endregion
wr.buffer = new byte[65535];
wr._socket.BeginReceive(wr.buffer, 0, 65535, SocketFlags.None, ReceiveData, wr);
AnnounceNewConnection.Invoke(wr);
_socket.BeginAccept(AcceptConnections, new Wrapper());
}
catch (Exception e)
{
Console.WriteLine(e);//write an exception
}
}
private void ReceiveData(IAsyncResult result)//Receiving Data
{
try
{
Wrapper wr = result.AsyncState as Wrapper;
string IP = wr._socket.RemoteEndPoint.ToString().Split(':')[0].ToString();//Get UIP
if (Connections.ContainsKey(IP))
{
SocketError error = SocketError.Disconnecting;
int size = wr._socket.EndReceive(result, out error);
if (error == SocketError.Success && size != 0)
{
byte[] buffer = new byte[size];
Buffer.BlockCopy(wr.buffer, 0, buffer, 0, size);
AnnounceReceive.Invoke(buffer, wr);//The delegate
if (wr._socket.Connected)//Make sure socket is connected
wr._socket.BeginReceive(wr.buffer, 0, 65535, SocketFlags.None, ReceiveData, wr);//Start Receiving Data
}
else
{
if (wr._socket.Connected)
{
wr._socket.Disconnect(true);//Disconnect the client
}
byte connections = Connections[IP];
Connections.Remove(IP);
Connections.Add(IP, (byte)(connections - 1));
try
{
AnnounceDisconnection.Invoke(wr);
}
catch { }
}
}
}
catch (Exception e)
{
Console.WriteLine(e);//write an exception
}
}
}
So my question again clearly is : How to use SSL Stream with socket class like the ABOVE code

Answer 1

Replace the Stream class with the System.Net.SslStream class. In addition to the above code, call AuthenticateAsServer and pass the server SSL certificate in the WinSocket constructor.
