The Poison Pill. The Doomsday Files. Or simply, The Insurance.

Whatever you call the file Julian Assange has threatened to release if he's imprisoned or dies or WikiLeaks is destroyed, it's impossible to stop.

"It's all tech talk to say, 'I have in my hand a button and if I press it or I order my friends to press it, it will go off,'" said Hemu Nigam, who has worked in computer security for more than two decades, in the government and private sector.

"Julian is saying, 'I've calibrated this so that no matter how many ways you try, you're never going to be able to deactivate it,'" Nigam said. "He's sending a call to action to hackers to try it. To the government, he's also saying, 'Try me.'"

There's a reason Assange specifically announced -- on the Web -- that there is a 256-bit key encryption code that only a few trusted associates know that will unleash the contents of the 1.4 gigabyte-size file.

"He's saying don't even bother trying. It will take you so long to succeed that by that time, it will be too late," Nigam said. "Most of the time, you see a 56-[bit]key encryption. That's considered secure. When you are using 256, you are sending a message: 'I'm smart enough to know that you will try to get in.'"
