FW: another de-cryption



Descramble That DVD in 7 Lines

Using only seven lines of Perl code, Keith Winstein and Marc Horowitz have
created the shortest-yet method to remove the thin layer of encryption
that is designed to prevent people -- including Linux users -- from
watching DVDs without proper authorization.

Programmer Adam Back managed to squeeze the RSA algorithm into just two
lines of <http://world.std.com/~franl/crypto/rsa-guts.html> Perl.

Winstein says it's folly for MPAA and its allies to try to restrict a
526-character program that can be handed out on business cards. "I'm
showing the humor in trying to call these seven lines on a piece of paper
a device," he says

Winstein and Horowitz, an MIT alumnus, are both members of the MIT Student
Information Processing Board <http://www.mit.edu/sipb/> , the university's
social group for programmers and like-minded folks. They jointly developed
qrpff [Hamaker, Chuck] (the code) for a two-meeting seminar
<http://www.mit.edu/iap/dvd/> that Winstein taught earlier this year.
