I am using Rot13 to jumble up a small script I was wondering if it is possible to use Rot13 on the source of a perl file without using the Filter::Util module? I dont have access to that module so if possible I'd like to use this method of jumbling the source without it.
I know the actual process or de-jumbling the rot13 method is so simple using a tr/// but how do i approach this if it is the source of that perl file?
