Cryptkeeper is a Linux system tray applet that manages EncFS encrypted folders. It is a handy tool for saving your private data into an encrypted folder, the folder default is hidden and need password to unencrypt using Cryptkeeper applet.

Note: I would recommend TrueCrypt if you’re planning to encrypt larger collections of data that you want really secure. Just use Cryptkeeper for less sensitive data. Although the encrypted folder is hidden, it still can be shown by ctrl+h if you do know where the folder is and the data in the folder can be deleted(data can’t be read).

Installation

Install this applet is very easy, use apt-get command or Ubuntu Software Center:

sudo apt-get install cryptkeeper

For Ubuntu 11.04 Unity, you may need this command to allow it showing in system tray and then logout and back in:

gsettings set com.canonical.Unity.Panel systray-whitelist "['all']"

Create new encrypted folder

Click the applet and choose “New Encrypted Folder”:

Input a name for the encrypted folder and choose where to mount it:

Input a password and repeat and click Forward:

Now, this encrypted folder should be created and shown under Encrpted Folders in picture 1 just like “home/wriath/Pictures/Pic”. By default it is hidden. When you tick the folder in picture 1, you will be asked for password to access it.
