# Ubuntu, LUKS disk encryption


Found 
[this very nice howto](http://www.hermann-uwe.de/blog/howto-disk-encryption-with-dm-crypt-luks-and-debian),
which I almost followed to the letter, except I did it in Ubuntu and
currently more stuff is working out of the box, so you don't need to
do *all* the steps. 

I'm working on an USB stick which is `/dev/sdb1` in my system.

Steps I did take:

1. `apt-get install cryptsetup hashalot`
2. `cryptsetup --verbose --verify-passphrase luksFormat /dev/sdb1`
3. `cryptsetup luksOpen /dev/sdb1 funnydiskname`
4. `mkfs.ext4 -O extents,uninit_bg,dir_index /dev/mapper/funnydiskname`
5. `cryptsetup luksClose /dev/mapper/funnydiskname`

Now pull out your disk and re-insert. If everything went well, your
GNOME, XFCE, KDE env should now popup an 'This disk is encrypted, please
enter the passphrase' question.
