I am running Debian/Gnu Linux with the 2.4.22 kernel. I would like to
use losetup to encrypt a raw disk (/dev/hda?). Is this possible?

Can I use

    dd if=/dev/zero of=/dev/hdaX count=(size of /dev/hdaX)

to initialize, then

    losetup -e AES --keybits 128 /dev/loop0 /dev/hdaX

to encrypt/decrypt it?

Thanks, Ralph
