Stunnix Perl-Obfus

Stunnix Perl-Obfus is a unique solution for protecting your valuable intellectual property from possible Perl source code piracy/studying/rework. It's an advanced and extremely reliable obfuscator for the Perl source code. It converts the Perl source files (.pl and .pm) into highly mangled and obfuscated forms, making them extremely difficult to study, analyse, reuse, or re-work for competitors or customers, while fully retaining functionality of the original source code. It's not a compiler to machine code, and the obfuscated form will still be the usual Perl source code, and so will work on all platforms the original source worked on.

            Hey pal, there's a demand for child porn. Go post a Other/Proprietary tarball here?

            This kind of thing really doesn't have it's moral place here.

            2 all: go to scoop and ask to remove it? (sorry stunnix)

            Like in "bogus security" or "bogus protection". Yes, it is
            harder to read obfuscated code, but as long as it's perl it's easily reversed to a readable form.

            Obfuscation as practiced within the perl community has nothing to do with protecting source code.

            Okay, so you cannot know that '$z5da4d3837d' corresponds with '$files' after obfuscation. But the code is not really hard to read and understand when you use distinguishable dictionary words, there is already a Perl module for that:

            You are missing the point ...
            Perl was never intended to be "un-readable". I can't think of a single line of Perl code I would ever want to "hide"/"obfuscate" from anybody.

            If you want to code closed source commercial apps - use C.

            Let's also consider some of the practical issues:

            * Debugging. If something goes wrong, I must _hope_ it's not the mangled code. There is no easy way to know for sure. Personally I would not trust this at all.

            * Version control. What meganism is there to tie the mangled code to an original source file? Also consider the line: "Unique! Means to make analysis of changes between different releases of the obfuscated product more difficult" ( source: http://www.stunnix.com/prod/perl-obfus.shtml ).

            * Easy to reverse. This has been commented on already. I have experimented a bit and it took about 30 minutes to solve the puzzle ( given your own example ). The only thing I haven't done was to give the function names a more interesting name, but then again - it's easy to add.

            * $879 !!! Are you serious? This is the best get-rich-quick-scheme I have ever seen. You can purchase commercial compilers for less then that.

            In a nutshell then - I think you people should grow up. I hope somebody that did indeed make the mistake of purchasing this junk take you to court - There must be some kind of law against this obvious attempt to make people belief stuff that just isn't true.

            To all prospective buyers out there - give this a miss.

            Cheers
