Oh, say it ain't so! ;-)

In the NBC TV episode of /Chuck/ a couple of weeks ago, the NSA cracked
"a 512-bit AES cipher" on a flash drive "trying every possible key".
"Could be hours, could be days."  (Only minutes in TV land.)
(Chuck Versus The Fat Lady, 4th segment, at 26:19)

It's no wonder that folks are deluded, pop culture reinforces this.
