I am writing a piece of software in C++ which is targeted at a market in which software is traditionally heavily cracked (or at least, attempted to be). I realise that nothing can be completely protected, however I feel that trying would be a good idea and also I think some of the specifics of the situation that I'm in might be helpful.
Firstly, it would not be annoying to the user that they must have an internet connection to use the software. I hate it when games etc. do this too, but the software requires an internet connection to function anyway due to its purpose, so this wouldn't hinder a normal user.
Secondly, it depends fairly heavily on external scripts written by me and/or supplied by third-parties, so I can have these stored on some website somewhere meaning that people who crack the software will have to also track down new copies of the scripts, which may annoy them into becoming legit.
Thirdly, new versions will, by definition due to what the app does, have to be released very often, weekly or every two weeks max. The program will obviously have an autoupdater, but since I am churning out (required to function) updates so often, any sort of key-based encryption or whatever could possibly have the keys/method change every update, and I am capable of breaking existing cracks when they do happen.
Does anyone know of any available solutions or techniques I could implement which fit the bill?
