Kim Dotcom’s newly launched Mega is determined not to get screwed over by the Feds the way MegaUpload did, and the trick is encryption, lots of encryption. Mega’s really going that extra mile too; it’s using your random mouse and keyboard data to strengthen your crypto keys.

But if you know anything about computers, you know they’re horrible at generating random numbers. They just can’t do it. Instead, they’ll take obscure variables like your computer’s clock time, and spin those out into something pseudorandom. If somehow you can find out the variable though, it’s not random at all.
