LUKS in-place conversion tool


luksipc is a tool to convert (unencrypted) block devices to (encrypted) LUKS devices in-place (therefore it's name LUKS in-place conversion). This means the conversion is performed without the need of copying all data somewhere, recreating the whole disk (i.e. create a LUKS device, create a new filesystem on the mapped LUKS device, copy all data back). Instead, the process is reduced to:

 1. Unmounting the filesystem
 2. Resizing the filesystem to shrink about 10 megabytes (2048 kB is
    the current LUKS header size -- but do not trust this value, it
    has changed in the past!)
 3. Performing luksipc
 4. Adding custom keys to the LUKS keyring
