If you're using a 128 bit hash, and your key+password is less than 16 characters, then the shortest reverse lookup is probably the right one.

If we include the fact that key+password are usually made up of typeable characters, then the shortest reverse lookup that is typeable is probably the right one out to 19 or 20 characters.

I suspect that fairly few people use a long enough secret key to provide protection against this fact. But if you do, then you're right that the secret is still protected.
