Hi all,

I am currently running Fedora Core which is pretty much RH9, but I am new
to redhat distos. I've been using gentoo since it's creation, and
slackware before that. My question is regarding using loopback drivers
for encrypting a whole disk on the fly.

I had this set up in gentoo. It worked quite nicely with little or no
performance loss. basically the disk was encrypted with 256bit encryption
and all requests to access the drive were sent through a loopback driver
in order to decrypt it.

Does anyone know if I can do the same type of setup within redhat / fedora?
however, this time I would like to use pass phrase authentication with gpg
instead of a normal passcode.

Thanks,

Dereck
