encryption. There are three modes:

* Directly encrypt a disk image on a host system. The image can then
  be deployed somewhere else
* Prime a disk image by adding code to the initrd of the image that
  encrypts the image on first boot
* Include the initrd code already when building an image. The image
  would then encrypt itself on first boot.

In general the tool is developed with [kiwi](https://github.com/OSInside/kiwi)
in mind. It assumes that the image contains a single root fs using btrfs in the
third partition. Both grub2 and systemd-boot are supported. The tool generates
a

Example to directly encrypt an image:

disk-encryption-tool -v SLE-Micro.x86_64-5.4.0-Default-GM.raw

Example to prime a plain text image to encrypt on first boot:

disk-encryption-tool -v --prime SLE-Micro.x86_64-5.4.0-Default-GM.raw

When run on first boot the tool integrates with
[jeos-firstboot](https://github.com/openSUSE/jeos-firstboot/). The encryption
in initrd deploys an automatically generated recovery key, compatible with
[systemd-cryptenroll](https://www.freedesktop.org/software/systemd/man/latest/systemd-cryptenroll.html).
Later in the real root a jeos-firsboot module then offers to deploy
either the root password or another custom passphrase as well.

Parameters for cryptsetup-reencrypt(8) can be passed via
`/etc/encrypt_options`. One option per line, e.g.

--type=luks1
   --iter-time=2000

It's also possible to integrate with combustion. The combustion
script would have to look like this:

#!/bin/bash
    # combustion: prepare
    if [ "$1" = "--prepare" ]; then
        echo 12345 | disk-encryption-tool -v
    else
        echo root:12345 | chpasswd

Convert a plain text kiwi image into one with LUKS full disk
encryption. Supports both raw and qcow2 images. It assumes that the
third partition is the root fs using btrfs.
After encrypting the disk, the fs is mounted and a new initrd
