C# SSL TcpListener TcpClient

I'm making a game login/lobby in .N开发者_如何转开发ET. I want to handle the login portion via SSL over TcpClient & TcpListener. How do I go about working with SSL with these 2 classes? I don't want any kind of cert that needs to be installed on the client machine. I'd prefer that I would be able to just hardcode the public key right into the program, yet most example I see start dealing with cert stores.

Any advice?

Secure Socket Layer (SSL) only works with cert stores, if you want to use SSL then you can't avoid this.

However you can simply do encryption using an cryptostream.
