I just started to work for a new customer. He sell access to his Cloud App, written in PHP/MySQL. Recently he got an inquiry from two of his customers asking if he could install the tool locally.
Before doing so, he would like to ask one of his representative to perform a demonstration on site, and asked me if I could create a portable version of the app on USB Drive.
There's no issue with that, except he want the PHP Scripts to be protected/encrypted, so they could not be just copied over.
Do you know how I could manage to do this? Do I have to set up a virtual machine with protected contents? Should I use any existing tool allowing to protect things like that?
