dm-crypt with LUKS
------------------

LUKS with dm-crypt has better encryption and makes it possible to have multiple passphrase for the same partition or to change the password easily. To test if LUKS is available, simply type # cryptsetup --help, if nothing about LUKS shows up, use the instructions below Without LUKS. First create a partition if necessary: fdisk /dev/sdc.
Create encrypted partition

# dd if=/dev/urandom of=/dev/sda3          # Optional. For paranoids only (takes days)
# cryptsetup -y luksFormat /dev/sda3       # This destroys any data on sda3
# cryptsetup luksOpen /dev/sda3 sda3
# mkfs.ext3 /dev/mapper/sda3               # create ext3 file system
