In Case you haven't heard, the CVS Camcorder and cameras can be hacked, and a brute forcer is in the works. Please register, and use the program called OneTimeBrute. It runs fine under wine, and there is a linux version, although I haven't gotten it to compile. The ones left to do are on the last page (pg 7)

It involves hacking one-time-use digital video camcorder & still cameras, the type that can only be used once.

This way you get to re-use them.

Wait... Are you saying they build digital cameras that technically can be used many times but cripple it with an artificial limit so people must throw it away on the ever growing trash mountain after one use and buy a new one even though it actually could handle many more uses?

What a wonderful society where development funds are spent on ideas to make products less useful. That kind of counter-productive, wasteful stupidity should be illegal! ](*,)

Are you sure they throw away the cameras after printing whats on them? They can be sold again if they arent to shabby...

I wonder why they bother cracking those cameras encryption anyway, they can't be very good and that seems like a serious forum... probably bc of the challenge. "Why do men (or women) climb mount everest? bc it's there ;D"

Yeah, "one-time use" is a misnomer. It's really a rental scheme... but for whatever reason, they don't want to call it that, and it's not structured that way legally. So, you buy the camera, you own it. When it gets full, you're supposed to bring it in to them; they convert the data to whatever format, and give the data back to you. They keep the camera, reset it, and resell it to someone else.

Brute force attacks are used to find passwords. They are primitive and slow unless you have a Mega-Computer or a networked attack.

You can get bruteforce programs off the net freely but they are useless on a strong password unless you want to wait for 500 years with a normal PC.


Theoretical limits

There is a physical argument that a 128 bit key is secure against brute force attack. It is argued that, by the laws of physics, in order to simply flip through the possible values for a 128-bit key (ignoring doing the actual computing to check it), one would need a device consuming at a minimum 10 gigawatts (http://en.wikipedia.org/wiki/Orders_of_magnitude_%28power%29#Gigawatt) (about the equivalent of eight large, dedicated nuclear reactors (http://en.wikipedia.org/wiki/Nuclear_reactor)) running continuously for 100 years. The full actual computationóchecking each key to see if you have found a solutionówould consume many times this amount.
