If it's not being read and rewritten, it's not being encrypted. It's as
simple as that. A cryptosystem that doesn't read the plaintext? How
does that work?
Give me an image if the disk and after suitable time and effort I have access to
the whole thing if only the directory entries are encrypted. So the tool in
question gives a false sense of security at best.
