Howto encrypt your filesystems

by xiando (DrEvil)

A loopback device is a quick nice way to make a encrypted filesystem.

If you have compiled loopback and cryptoloop support as a module, you need to load these first:

modprobe loop;modprobe cryptoloop;modprobe cipher-aes

Basically you run:

  losetup -e aes /dev/loop0 /dev/partition

You will be asked for a password. Then

  mkfs -t ext3 /dev/loop0
  mount /dev/loop0 /path/to/mount

alternatively, you can use a file instead of a whole partition:

  dd if=/dev/zero of=/file bs=1k count=100
  losetup -e aes /dev/loop0 /file
  mkfs -t ext3 /dev/loop0
  mount /dev/loop0 /path/to/mount
