I am curious, I am really not a C# programmer but I am trying to accomplish the usage of Rsa by using your code in 7.72 in general.

I am doing it like this:

`public static void Parse(Connection connection)
{
var message = connection.InMessage;

    if (message.GetByte() != 0x01)
    {
        Console.WriteLine("Invalid first packet.");
        connection.Close();
        return;
    }

    var clientOS = message.GetUShort();
    var version = message.GetUShort();

    message.SkipBytes(12);
    
    Rsa.DecryptAndReplace(message.Buffer, message.Position, message.Length);

    connection.SymmetricKey[0] = message.GetUInt();
    connection.SymmetricKey[1] = message.GetUInt();
    connection.SymmetricKey[2] = message.GetUInt();
    connection.SymmetricKey[3] = message.GetUInt();

    var accountNumber = message.GetUInt();
    var password = message.GetString();
    
    SendDisconnectLogin(connection, "hello world");
}`

But the result of the Rsa decrypted packet is always invalid, in C++ I can manage and debug this with ease but with C# I cannot. Maybe I am doing something wrong?
The Rsa numbers are the same as yours and I am using OTC with stock RSA to test it.

Hi Mtanksl,

Hope you're doing well. I'm a Unity developer currently working on an MMO server project. While digging around, I stumbled upon your code and gotta say, it's impressive!

Just a bit curious - where did you get the ideas to structure the server the way you did? Did you follow any specific papers or already established server structures?

Also, could you shed some light on how it scales? Can it handle a large crowd, say, 3k+ players, like some OT TFS servers do?
