luksipc - 0.04-3 main

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
