New page

'''<code>cryptsetup</code>''' is utility used to conveniently setup disk encryption based on dm-crypt kernel module. These include plain dm-crypt volumes, LUKS volumes, loop-AES and TrueCrypt compatible format.

==Example==
*Create an encrypted file system on a given partition:
fdisk -cu /dev/xvde1
cryptsetup luksFormat /dev/xvde1
cryptsetup luksOpen /dev/xvde1 vault
mkfs.ext4 /dev/mapper/vault
mkdir /vault

*Edit <code>/etc/fstab</code> and add the following line:
/dev/mapper/vault /vault ext4 defaults 1 2
*Create/edit <code>/etc/crypttab</code> and add the following line:
vault /dev/vda5

*Allow for automated boot with your <code>/vault</code> drive automatically mounted and password entered (this is a '''''very''''' bad idea, as it defeats the ''entire'' purpose of LUKS encrypted partitions):
echo -n "vault /dev/xvde1 /root/vault
echo -n "your_password" > /root/vault
chown root /root/vault && chmod 600 /root/vault
cryptsetup luksAddKey /dev/xvde1 /root/vault
