Now That's A Challenge

From CNN:

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 ... 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.

The widely available file, called insurance.aes256, has been around for months now and is analysed by geeks everywhere.
