Rapid destruction of the encrypted home directory without the possibility of recovery

I want to share with Habrasoobshchestvom recipe that can be useful when working with sensitive information leaks.

If you use Ubuntu and ecryptfs to encrypt a user's home directory, the next command will very quickly make your data unsuitable for recovery even by thermorectal cryptanalysis with just one reservation - if you managed to run the command before you physically remove your computer.

/bin/sh -c '/usr/bin/shred -uf /home/username/.ecryptfs/wrapped-passphrase && /usr/bin/gnome-session-save --force-logout'

You can even make a launch button for this command and assign it a HotKey.
