Charles Hannum has written a program to decrypt DVD's in C that is smaller than the perl 7-liner, qrpff, written by Keith Winstein and Marc Horowitz.

Waiting for the Tshirt (3.50 / 2) (#1)

This would make a much better Tshirt than the original DeCSS shirt.

Slap that C code on the front in large white letters and you'd have yourself a seller!

IOCCC (4.70 / 10) (#2)

Ok, so how many of you think that deCSS should be the most common artifact in this year's International Obfuscated C Code Contest? Not only does the subject matter lend itself well, it would also make quite a statement, don't you think?

Line noise (4.71 / 7) (#3)

I just had a thought.. (surprise, eh?) Considering how unintelligible that code looks, could one avoid prosecution by simply appending "//NO CARRIER!" to the end of the listing?

random noise vs. information (4.00 / 2) (#7)
by Glacky on Thu Mar 15, 2001 at 04:43:08 AM EST

If you listened to static (random noise) long enough, you'd eventually get a sequence that decrypted CSS. So much for 'circumventing a content protection mechanism' - who are they gonna sue then, Serendipity?

All noise is simply encrypted information.

And monkeys might fly out of my butt! (none / 0) (#8)
by jabber on Thu Mar 15, 2001 at 09:22:10 AM EST

Enough monkeys, all carrying typewriters of course.. This argument would probably not stand up in court though, since infinite monkeys would also eventually retype The Stand, but that would not make it public domain.

To continue the thought exercise (in futility) all information, known and unknown, coprighted, patented, secret and not, is encoded in the quantum fluctuations of the Universe which surrounds us. It's not in a vault, or sealed package in an RIAA drawer... Hell, anything on the radio and TV is beamed out into space! And the source code for Windows 2000 can be decoded from the vibrations of the atoms that make up the rug under my feet.

But such decoding would require reverse engineering of the encryption, and this makes the DMCA a very pesky thing. Of course, God is the patent holder on that cipher, and I don't think He would mind. God's EULA is a pretty simple 10 point list, and his license is even more permissive than the LGPL. :)

/me backs away from the deep end before going off of it...

That's small enough for a tatoo...

Just a rehash of the Perl (none / 0) (#9)
by KnightStalker on Thu Mar 15, 2001 at 12:02:49 PM EST

Use of commas to avoid brackets, bizarre #defines... nothing to see here, move along. It's not even ANSI C. :-)

Clean Version (none / 0) (#10)
by guinsu on Thu Mar 15, 2001 at 01:39:54 PM EST

Can anyone post a link to a nice clean, readable version? Even putting in line breaks doesn't make this readable.
