About the Perl Obfuscation Service
I needed to obfuscate a bunch of Perl scripts a while ago. Perl is famous for being naturally obfuscated, but I had something more extreme in mind. As the thought of further obfuscating my Perl scripts by hand horrified me, I looked around for a free automated solution.
Long story short, I didn't find anything decent, so I wrote my own. It's pretty neat, and handles (almost) all Perl constructs. I kept working out the bugs until it was powerful enough to obfuscate itself recursively an arbitrary amount of passes.
Anyway, the pricing for the commercial obfuscation stuff is absolutely outrageous:
"The Stunnix Perl-Obfus Single Developer License costs $879, and can be purchased online in our store. May be used by the same user on any number of machines. Full text of the license is here."
So I turned my obfuscator program into a web service anybody can use for free.
