Won't people know how to decrypt scripts then?
Your correct. It just prevents them from unintentionally viewing the scripts.The code you wrote is only slightly better (creating 256 different possibilities), but could just as easily be cracked by a simple piece of code (especially since the source code is made public). (Actually, I think what you wrote is similar to what they call ROT13?, except that it would be more like ROT256)
I was hoping for an encryption algorithm that is still hard to crack, even with the source code being made public.
I hope no offense is given. I'm not trying to put down your efforts. "I" didn't come up with anything better...
