Another privacy-related tip for you here. If you are using Ubuntu and are trying to get Cryptkeeper to work, stop! There’s another way – Gnome Encfs Manager.
In case you are wondering, both Cryptkeeper and Gnome Encfs Manager are graphical interfaces for Encfs (encrypted filesystem). It mounts as a folder in Nautilus and adds an extra level of security for important files (like your banking info, for example).
Sadly, Cryptkeeper is no longer compatible with Unity in its current form.
Instructions for installing Gnome Encfs Manager (GencfsM) can be found at the attached link, but in case that should disappear for some reason, I’ll add it below.
Gnome Encfs Manager can be used to create, mount and unmount EncFS folders and comes with GNOME Keyring and Ubuntu AppIndicator support. Also, the applications can mount EncFs folders at startup, useful if you use EncFS with cloud sync / storage services such as Dropbox or Ubuntu One.
sudo add-apt-repository ppa:gencfsm/ppa
sudo apt-get update
sudo apt-get install gnome-encfs-manager
