Perl Code Obfuscator (PCO) is a program for obfuscating and optionally encrypting Perl scripts.

It removes comments and blank lines, replaces variable, array, hash, and sub names, and handles string and numerical values.

It then outputs the obfuscated version to a new file (your original remains untouched) and creates a short report.

There are several things that need to be considered (see the readme.txt) and it may not work with all Perl scripts.
