Forgive me if this is a stupid question.
I'm using AT&T unix Version 5 release 3.2.2 ( UNIX System V/386 Release 3.2)
I have several simple scripts that are simple yet handle important realtime call proccessing tasks and remote control operations. These programs are my programs but are running on a system that is dialed into by the vendor once in a while.
Is there a way to encrypt a script yet still allow it to be runnable? I know that the simple answer is to write it in C and compile it but I don't have the means of doing that at the moment. (i.e. there is not compiler on the system)
You can try something similar to what gzexe does, but...
I thought of a few simple protections but they all involve decrypting before running.
