Script Encryption?

Here's the deal.  I've been writing a lot of scripts for work, and many of them have been getting used by more than just myself.  Many of these scripts contain our internal processes, and while the script itself is obviously not my company's property; the methods used in the script to get from point A to point B is.  Since we work with a lot of temporary contractors, I was wondering if there is a way to encrypt the scripts so that the processes performed by them do not easily get leaked to our competition.  We obviously have NDAs in place to prevent this, but that doesn't always stop people; and also doesn't cover someone's laptop being stolen with the scripts on it.  Anyway, is it possible to encrypt scripts for Photoshop; or am I just dreaming here?  If it is possible; could someone point me in the right direction?  Thanks for any help!
