Cryptkeeper is a GNOME applet for managing EncFS encrypted folders. To install it, make sure the Universe Repository is enabled and install it with Synaptic. Alternatively, install it from the command line with:

sudo apt-get install cryptkeeper

The installation should have added your userid to the fuse group. If it didn’t, you can add it with: sudo addgroup userid fuse where userid is your log in ID. Because your group settings have changed, you need to log out and log back in. Once you are logged back in, you can start Cryptkeeper from the menu with Applications->System Tools->Cryptkeeper.

You should see an icon in your System Tray that looks like a pair of keys. This can vary a bit based on your current icon theme. This is the Cryptkeeper icon.

1. Click mouse button 1 on the Cryptkeeper icon and select New encrypted folder.

2. Enter a name for your new folder and select a location for it. I’m calling mine safe and putting it in my home folder.

3. Click the Forward button.

4. In the next screen, enter a password twice and click Forward.

5. Click OK in the last screen. Depending on your Gnome settings, a Nautilus File Manager window may have popped up for your new encrypted folder. Cryptkeeper actually creates a small encrypted folder that it mounts as an encrypted drive. Create a basic text file in your new encrypted folder to try it out. To hide your encrypted folder, click the Cryptkeeper icon and uncheck the box next to it. To reopen your encrypted folder, just click on the Cryptkeeper icon and check the box next to it. Enter your encryption password at the prompt, and you’re in
