From the official website:
- Tomb is 100% free and open source software to make strong encryption easy to use.
- A tomb is like a locked folder that can be safely transported and hidden in a filesystem.
- Keys can be kept separate: for instance the tomb on your computer and the key on a USB stick.
Tomb aims to be a really simple to use software to manage "encrypted directories", called tombs. A tomb can only be opened if you both have a keyfile and you know the password. It also has advanced features, like steganography.
You can install Arch User Repository.AUR from the
Install AUR or AUR.
Tomb is meant to be used from the console as a single, non-interactive script. it also provides tomb-open, which is a simple interactive script to help you create a tomb, open it, retrieve keys from USB.
Tombs are operated from a terminal commandline and require root access to the machine (or just sudo access to the script).
To create a 100MB tomb called "secret" do:
# tomb dig -s 100 secret.tomb # tomb forge secret.tomb.key # tomb lock secret.tomb -k secret.tomb.key
To open it, do:
# tomb open secret.tomb -k secret.tomb.key
And after you are done:
# tomb close
For more information see
tomb -h and
To make usage of tomb even easier, you can use a GUI wrapper called gtomb. Find it here:AUR
It includes almost all features tomb offers, but is still in active development so use it with caution.
- steganography (to hide the key inside a jpeg/wav file)
- bind hooks: can mount some of its subdirectories as "bind" to some other. Suppose, for example, you would like to encrypt your .Mail, .firefox and Documents directories. Then you can create a tomb which contains these subdirectories (and others too, if you want) and create a simple configuration file inside the tomb itself; when you run
tomb openit will automatically bind that directories into the right places. This way you will easily get an encrypted firefox profile, or maildir.
- post hooks: commands that are run when the tomb is open, or closed. You can imagine lot of things for this: open files inside the tomb, put your computer in a "paranoid" status (for example, disabling swap), whatever.
