I understand Moises but you need to think about who you want protection from. If it is from the casual user then Konxise is fine. If it is from more sophisticated hackers then you will want to go for stronger protections. And also think about what the potential for loss is if this code gets out. The more serious the potential loss the stronger the protection you will want.
