Encrypt files in Dropbox Folder

Putting sensitive files on a cloud drive like Dropbox can be dangerous no matter how secure they claim their systems are. The basic fact is that any system can be hacked, it happens every day. If you are using Dropbox to backup and share critical files like I am the first thing you want to do is to setup two factor authentication. In Dropbox the 2nd factor authentication sends a six digit access code in the form of a text message to your mobile phone. While this extends your security it alone will not totally protect your files. In this article I will take you step by step in setting up a encrypted Dropbox folder using EncFS and Ubuntu. 

Step 1:

Install EncFS in Ubuntu

sudo apt-get install encfs

install gnome-encfs-manager

sudo add-apt-repository ppa:gencfsm/ppa

sudo apt-get update && sudo apt-get install gnome-encfs-manager

Step 2:

Create a directory inside your Dropbox folder. For this example I created a folder called crypt.

Start gnome-encfs-manager and set up a new stash by clicking the + sign.

Set the directory to encrypt to a folder inside your Dropbox folder.

Set the mount directory wherever you want, the default is fine just don't put it in your Dropbox folder. 


E
nter a strong password with at least 20 characters and click "Create".


Edit the new stash by selecting "Stash" and then "Configure" from the menu and check "Mount on Startup" and "Save Password in keyring" to save the password in the gnome keyring.

        
You should now have your encrypted drive mounted, it will be displayed like a mounted usb-drive.

 

Importing the drive on other computers:

1. Wait for all files to sync on Dropbox.
2. Start gnome-encfs-manager and set up a new stash.
3. encfs-manager will detect the drive and import it.
4.  Set the mount directory wherever you want (default is fine) and click "Import"
5. Edit the new stash as described above.
6. You will be asked for your password on first mount.
