I know that's an old topic, but I'm developing Kontakt libraries by some years and sell them through Kontakt Hub, and... though I make every times the vain password protection, I really don't care if someone can "steal" my scripts. I mean, very good crackers can find the way to enter in very complex encrypted codes so being able to access a script in KSP will be a simple walk. Some friends told me that they find my libraries in some pirate sites, so as Mario, wisely said " There's always a key, for every lock." So why stay there and mull over it? I give up my arms because I don't have the time or the desire to find impossible solutions.
