r some of your applications. You could first unlock your tomb and start an application that requires said config files. If someone tries to start that application without unlocking the tomb, the application will seem like it’s just unconfigured.
Once you’re done organizing your X Factor rehearsal videos inside your tomb, you can close it in one of two ways. Either using the close command or the slam command.
tomb close [<name of tomb> | all] tomb slam all
If you have more than one tomb open, you can either specify the name of the tomb to be closed or use all for closing all currently open tombs. The close command will fail if the tomb is in use by a running process.
If you’re in a hurry and need to close your tombs regardless of running processes you can use the slam command. This may result in unsaved data loss to files that are in use, so use with caution.
More Security Through Obscurity
One of the things to be aware of when using Tomb is that there isn’t any cleanup process. That means once you’re done with your tomb, you need to ensure the key is removed if it exists on the same machine.
Keeping a tomb and key on the same machine creates an element of risk. There are ways to be a little sneaky and hide keys in plain sight. Take this folder for example:
It contains some family pictures, all with sequential names. At first glance, nothing seems out of place. Anyone looking at these pictures would be none the wiser. Now, look at this picture in particular:
This picture has a lot more to it that meets the eye. Embedded inside this picture is a key used to unlock a tomb hidden using steganography. Impressive right? If you’re feeling like James Bond and would like to do this type:
sudo apt install steghide
To hide a key inside a JPEG type:
tomb bury -k secrets.tomb.key Picture-name.jpg
After entering the password for your key file, you can now delete the key file entirely. This means that there will no key file left in plain sight. Instead, it will actually be hidden inside a JPEG. To get the key back out run:
tomb exhume -k tempsecret.key Picture-name.jpg
Once your key has been exhumed or extracted, use it to open its respective tomb. After you’ve locked the tomb, feel free to delete the key as it can always be exhumed from the JPEG.
Finally, ensure your tombs are hidden among other files as opposed to just keeping them in the root of your drive. Give them names that will allow them to blend in with the noise.
Keep It Secret, Keep It Safe!
Tomb brings with it some great features. In the extras directory, there are a few other helpful tools like a GUI interface and tray icons.
Tomb adds an extra layer of security for those extremely sensitive files that you may have. The theming convention also adds a little fun to the experience! Your skeletons can now rest in peace.
