Hello,

I hope this is the correct NG to post such a question,
but I need some advice from experts about something is
"floating" in my mind.

I was playing around with some disk encryption tools,
namely truecrypt, dm-crypt and luks, and comparison
of features was, of course, happening.

So, truecrypt has, among other things, the possibility
to have cascade encryption and the encrypted header.

While truecrypt is also available under Linux, I was
wondering if it would be possible to create an equivalent
system using dm-crypt and luks.

The concept would be to use luks over a dm-crypt device,
which is over another dm-crypt device.
