Actually, contrary to what everyone says, there is one way to encrypt the entire script, as in making it, from the #!/usr/bin/perl to the very end. It will not hold up well in extensive scripts, or large scripts, but it does work nonetheless.

I'm not sure if they still offer it, but WorldWideScripts.com makes a program called PerlEncoder. You gotta buy it if you wanna use it unlimited.

Though, the sad thing is that in scripts, it's nearly impossible to encrypt every single park of your code, unless you use some sort of strong randomizing method, then eval() it.. Though I don't know if eval would work under alot of code..

My strongest recommendation is just encrypt those things you don't want viewed, or editable, such as your copyright link that's displayed..
