AES 192 or AES 128 may actually be a more secure choice than AES 256,
until they work out the following:

That having been said, unless a major corporation or intelligence agency
is interested in your data, the relative "strength" of one of these
ciphers over another are mostly academic. Almost nobody would bother
trying to use sophisticated cryptanalytic attacks, because there are so
many avenues of attack that are much easier, cheaper, and still very
effective.

E.G. is your computer physically guarded 24/7? If not, how do you know
someone hasn't put a keylogger on it? Hey--it's easier than a related-
key attack with 2^117 complexity.
