Log as root and install cryptsetup
thomas@pavillon-t546fr:~$ sudo -s root@pavillon-t546fr:~# apt-get install cryptsetup
Load the needed Kernel modules using modprobe
root@pavillon-t546fr:~# modprobe dm_crypt root@pavillon-t546fr:~# modprobe dm_mod
Then load the aes module:
root@pavillon-t546fr:~# modprobe aes_generic
Important: if you are running a Plug-computer like TonidoPlug or SheevaPlug, load the module mv_cesa. To see the available crypto modules, run the command
cat /proc/crypto | less
Create the crypted partition
