Protect scripts from unwanted users

[Johana]

Is it possible to protect the ahk scripts I've made? I know I can compile them into exes, but is there any other way to protect them from being viewed = source code? encrypting it somehow?

[evilC]

This is a fundamentally unsolvable problem. AHK is an Interpreted language, meaning that even when you "Compile" an AHK script, all you are really doing is bundling the interpreter with the source code of your script.
There is absolutely no way you can ever stop someone who knows what they are doing from being able to see the source code of an AHK script.

maybe see script from user 'feiyue'

encoded example, run this script as xy.ahk

Code: Select all
