I've never needed to encrypt my source code, since most of the time I work for customers whom pay for my development and source code. The other few occasions I didn't bother to encode it, since these customers always return to me for updates and new development.

But it's interesting to know what's out there and what the benefits are in that rare occasion where I might need it.

Don't worry, I won't encrypt my postings here since I believe it's also good to share knowledge and improve development coding by using usable code snippets and real situations.
