The obvious problem is that I _don't_ want security by obscurity - I want
security by tried and tested algorithms such as AES. You seem to confuse
"obscurity" (as in "I want to hide how it is done") with "secrecy" (I'll
happily tell you how it is done because you won't be able to do anything
unless you discover my secret key"). The distinction between these two is
the reason why e.g. TrueCrypt works.
