EncFS is primarily a command-line tool that you’ll find in the repositories of virtually every desktop distribution. While it doesn’t have an official graphical front-end, Gnome users can use the GnomeEncFSManager to manage and mount encrypted directories. However, you’ll have to switch to the terminal to set up EncFS encrypted folders. The program requires two directories be used to keep encrypted and decrypted files. It’s common practice to store the encrypted files inside a hidden directory. When you invoke EncFS it prompts you to select one of two configuration modes. There’s the predefined paranoia mode that uses AES cipher with a key size of 256 bits. Advanced users can run EncFS in expert mode, which enables you to manually pick the various encryption settings. Similarly, when you mount a new encrypted directory, you get two pre-configured settings with different encryption settings.
