Tomb aims to be a free and open source system for easy encryption and
|
|
|
|
|
backup of personal files, written in code that is easy to review and
|
|
|
|
|
links shared OS components.

|
|
|
At present time, Tomb consists of a simple shell script (Zsh) that
|
|
|
|
|
uses using standard filesystem tools (GNU) and and the cryptographic
|
|
|
|
|
API of the Linux kernel (cryptsetup and LUKS).
|
|
|
|
|
|
|
|
|
|
In future Tomb will grow to facilitate proper use of encryption by
|
|
|
|
|
unexperienced users, probably also prividing a graphical user
|
|
|
|
|
interface, as well a porting to Apple/OSX.

** Who needs Tomb
|
|
|
|
|
|
|
|
|
|
Our target community are desktop users with no time to click around,
|
|
|
|
|
sometimes using old or borrowed computers, operating in places
|
|
|
|
|
endangered by conflict where a leak of personal data can be a threat.
|
|
|
|
|
|
|
|
|
|
If you don't own a laptop then it's possible to go around with a USB
|
|
|
|
|
stick and borrow computers, still leaving no trace and keeping your
|
|
|
|
|
data safe during transports. Tomb aims to facilitate all this and to
|
|
|
|
|
be interoperable across popular GNU/Linux operating systems.
|
|
|
|
|
|
|
|
|
|
** How does it works
|
|
|
|
|
|
|
|
|
|
Tomb generates 'key files' and protects them with a password choosen
|
|
|
|
|
by the user; the key files are then used to encrypt loop-back mounted
|
|
|
|
|
partitions, like single files containing a filesystem inside: this way
|
|
|
|
|
keys can be separated from data for safer transports when
|
|
|
|
|
required.
|
|
|
|
|
|
|
|
|
|
** Stage of development
|
|
|
|
|
|
|
|
|
|
Tomb is an evolution of the 'mknest' tool developed for the dyne:bolic
|
|
|
|
|
GNU/Linux distribution, which is used by its 'nesting' mechanism to
|
|
|
|
|
encrypt the Home directory of users.
|
|
|
|
|
|
|
|
|
|
As such, it uses well tested and reviewed routines and its shell code
|
|
|
|
|
is pretty readable. The name transition from 'mknest' to 'tomb' is
|
|
|
|
|
marked by the adaptation of mknest to work on the Debian operating
|
|
|
|
|
system, used by its author in the past 3 years.
|
|
|
|
|
|
|
|
|
|
** How can you help
|
|
|
|
|
|
|
|
|
|
Code is pretty short and readable: start looking around it and the
|
|
|
|
|
materials found in doc/ which are good pointers at security measures
|
|
|
|
|
to be further implemented.
|
|
|
|
|
|
|
|
|
|
Best of all at this stage would be if you like to code a Graphical
|
|
|
|
|
Interface, possibly in QT4, that would use the script to make simple
|
|
|
|
|
operations: something pretty easy and intuitive, with a few big
|
|
|
|
|
buttons, for unexperienced users, can be a good start.
|
|
|
|
|
|
|
|
|
|
** Aren't there enough encryption tools already?
|
|
|
|
|
|
|
|
|
|
I've felt the urgency of publishing Tomb for other operating systems
|
|
|
|
|
than dyne:bolic since the current situation with TrueCrypt[1] is far
|
|
|
|
|
from optimal. TrueCrypt makes use of statically linked libraries, its
|
|
|
|
|
code is not hosted on CVS nor considered free[2] by GNU/Linux
|
|
|
|
|
distributions because of liability reasons, see Debian[3], Ubuntu[4],
|
|
|
|
|
Suse[5], Gentoo[6] and Fedora[7].
|
|
|
|
|
|
|
|
|
|
Seen from this perspective, Tomb is intended as a rewrite of most
|
|
|
|
|
functionalities offered by TrueCrypt in a new application, confident
|
|
|
|
|
it won't take much relying on previous experience and aiming at:
|
|
|
|
|
|
|
|
|
|
- short and readable code, linking shared libs and common components
|
|
|
|
|
- easy graphical interface, simple for ad-hoc (DIY-deniable)
|
|
|
|
|
- transparent and distributed development hosted using GIT
|
|
|
|
|
- GNU General Public License v3
