CryptoAPI on /


Hi all. I'm thinking about toying around with encrypting my entire root partition (including swap). It is on a laptop with 80MB of memory. I was wondering if anybody has any experience with this and can tell me how much of the system resources something like this would suck up.

Thanks in advance.

Well, that's not really the technique that I was going to use. That uses large files that you mount as encrypted filesystems, rather than encrypting the entire partition. Here's what I plan to do:

1) tar.bz2 entire current system of slack. Send it over to my main box and burn it on a cd.

2) Create a boot floppy w/ cryptoapi enabled so that I can make 2 partitions, /dev/hda1 (8MB... /loader) will be used to mount encrypted /dev/hda2 (/).

3) Unpack the contents of my backup cd onto the newly created partitions and see if it works.

4) repeate steps 1-3 over and over again till the freak'n thing works

I'm using this as a guide for the encryption part:

But I was just wondering if this is going to suck up a crapload of memory.... Anybody done something like this before?

Or does anybody have any good baseline tests I can do so I see what it takes up?
