Uniquement quand on a rien à cacher... comme des fichiers avec des mots de passe, des signatures numérisées, des projets industriels...

Installer les dépendances requises :

$ sudo apt install zsh file sudo gnupg cryptsetup pinentry-curses

Télécharger Tomb depuis : https://files.dyne.org/tomb

$ tar xvfz Tomb-2.9.tar.gz

$ cd Tomb-2.9

$ sudo make install

L'aide :

$ tomb -h

$ man tomb

Once installed one can proceed creating a tomb, for instance:

$ tomb dig -s 10 secrets.tomb (dig a 10MB Tomb)

$ tomb forge secrets.tomb.key (create a new key and set its password)

$ tomb lock -k secrets.tomb.key secrets.tomb (format the tomb, lock it with key)

When this is done, the tomb can be opened with:

$ tomb open -k secrets.tomb.key secrets.tomb (will ask for password)

To open it, do

$ tomb open secret.tomb -k secret.tomb.key

and after you are done

$ tomb close

or if you are in a hurry

$ tomb slam all

The key can also be hidden in an image, to be used as key later

$ tomb bury -k secrets.tomb.key nosferatu.jpg (hide the key in a jpeg image)

$ tomb open -k nosferatu.jpg secrets.tomb (use the jpeg image to open the tomb)

Or backed up to a QRCode that can be printed on paper and hidden in books. QRCodes can be scanned with any mobile application, resulting into a block of text that can be used with -k just as a normal key.

$ tomb engrave -k secrets.tomb.key (also an image will work)

Et ça marche
