  This hook allows for an encrypted root device.

  For non-LUKS devices, use the kernel command line option
    crypto=hash:cipher:keysize:offset:skip

  For LUKS devices, no command line option is required unless
  you want to use a key file on an external device, in which
  case use
    crypto=keydev:keydevfs:keyfile
  where keyfile is relative to the root of the keydev filesystem.
    eg: crypto=/dev/sda1:vfat:keys/root.key
  Note that you may need to include extra modules in your
  mkinitcpio.conf, such as vfat and nls_cp473. Removing autodetect
  from HOOKS or placing filesystems before autodetect should also
  work. In addition, you may need, for example, the usb hook.
