World's first DeCSS executable prime number

Math professor Phil Carmody, who in March of this year managed to
encode the DeCSS source in a prime number, has upped the ante by
producing a prime number which represents an executable version of the
banned CSS descrambler.

Legally this is all a bit squishy, as the DMCA forbids us to make
available an access-control circumvention device. All well and good,
not that we've tended to care what the DMCA allows or forbids; but
this item is also the fruit of mathematical research which the public
certainly has a right to see.

It's a fine legal paradox for the recording industry to chew on. Is
research illegal because it could in some tiny degree weaken their
monopoly over the production and distribution of digital media? Or
does the public's right to be informed of academic developments make a
circumvention device legal when it also exhibits academic value?

In practical terms, we have to wonder if there's anything to be gained
from objecting to such an exercise. Would the industry dare try to
chill research and journalism, with the public-relations nightmare
that entails, merely to maximize their profits? We wonder. They
certainly lost their nerve over the SDMI debacle
http://www.theregister.co.uk/content/6/21086.html.

And anyway, isn't the public's right to exchange information
ultimately a superior concern? Which is not to say that profits don't
matter -- but just that some things matter more.

"I'm a firm believer in authors' and artists' rights, the rights that
are protected under copyright," Carmody writes on a Web page detailing
his latest potentially illegal prime number
http://asdf.org/~fatphil/maths/#Smallest. "Ripping off DVDs with no
intention to buy the originals is illegal in almost all countries in
the world, and correctly so."

"However, I do not believe that the current implementation of US law
is a sensible one," he continues. "I believe it's logically
inconsistent, and is biased towards the interests of multinational
publishers and against consumers."

We couldn't agree more. So here's that fascinating prime number, which
incidentally just happens to defeat CSS:
