Minimalistic command line tool based on Linux dm-crypt and LUKS, trusted by hackers since 2007.

You can keep your volumes secure and easily manageable with simple commands.

Create a new 120MiB secret.tomb folder and lock it with a new secret.tomb.key file.

 $ tomb dig   -s 120 secret.tomb
 $ tomb forge -k secret.tomb.key
 $ tomb lock  -k secret.tomb.key secret.tomb

To open it, do

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

And after you are done

 $ tomb close

Or, if you are in a hurry, kill all processes with open files inside your tomb and close it.

 $ tomb slam
