Re: [Thinkpad] Thinkpad Hard Drive Passwords

A one time truly random key that is as long as the data should not be
breakable, even in theory.

"astronomically" long is a function of computing power. with sufficiently
fast processing, "astronomically" long can become quite manageable.

It's all a function of how much time and effort it's worth to protect your
data.
