Socket Servers

I’m currently developing an online game for a client using The Server Framework. I didn’t realise that it was an online game when they originally contracted me. It’s become a useful example of emergent requirements. Each time I think the project is complete they come back to me and say “and now we want you to quote for doing X”… Almost a year ago I published a series of articles on a piece of code that allows you to write TCP/IP servers on Windows machines.

OpenSSL is an open source implementation of the SSL and TLS protocols. Unfortunately it doesn’t play well with windows style asynchronous sockets. This article - previously published in Windows Developer Magazine and now available on the Dr. Dobbs site - provides a simple connector that enables you to use OpenSSL asynchronously. Note: If you need high performance SSL over TCP/IP then this is available as an optional part of The Server Framework; see here for details.
