encryption? Anyone good at explaining how it is done?

Hi!

Didn't really know where to put this, so move it if this is the wrong part of the forum...

Well, my question to everyone is, how many of you use cryptation on your partitions? and if so, can someone write a tutorial in the wiki on how to do it?

I've been looking for good tutorials, and I can't seem to find any that are good...I would really like to start cryptateing my partitions, I know that it often aint that hard to break for a fbi-guy, but it might make it harder for people that aint suppose to have my data ...

The problem is that I don't feel confident how it works...so if anyone wanna explain and maybe put something up in the wiki that would be great !!

A terse example of creating an encrypted filesystem image. You can do it with real block devices (/dev/hda1) too.

# dd if=/dev/zero of=fs.img bs=1024 count=1048576
# losetup /dev/loop/0 fs.img
# cryptsetup create myfs /dev/loop/0
# mke2fs /dev/mapper/myfs
# mount /dev/mapper/myfs /mnt
< read/write/copy >
# umount /mnt
# cryptsetup remove myfs
# losetup -d /dev/loop/0

The losetup stuff is only required since I'm using a file to store my filesystem. If you use a real block device, you don't need any loop devices.
