EncFS creates a virtual encrypted filesystem which stores encrypted data in the rootdir directory and makes the unencrypted data visible at the mountPoint directory. The user must supply a password which is used to (indirectly) encrypt both filenames and file contents.
If EncFS is unable to find a supported filesystem at the specified rootdir, then the user will be asked if they wish to create a new encrypted filesystem at the specified location. Options will be presented to the user allowing some control over the algorithms to use. As EncFS matures, there may be an increasing number of choices.
EncFS offers several advantages over other disk encryption software simply because each file is stored individually as an encrypted file somewhere else in the host’s directory tree.
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
Once installation of cryptkeeper is done, you can start Cryptkeeper from the menu with Applications > System Tools > Cryptkeeper, now, you You should see an icon in your System Tray that looks like a pair of keys.
Creating encrypted Folder:
* Click first mouse button on the Cryptkeeper icon and select New encrypted folder.
* Enter a name for your new folder and select a location for it.
* Enter a password twice and click Forward.
* Click OK in the last screen.
After this you can keep all your important files under this folder.
If you would like to have Cryptkeeper automatically startup when you log off or restart the system, then you’ll need to go into System Settings > Startup Applications, and add the application to the list.
