How to Easily Encrypt/Decrypt Files In Ubuntu One

Previously, we have shown you how to encrypt your files before upload to the Dropbox server. The method described in that article is using the Encfs method, which requires you to dabble with the command line. While you can use the same method to encrypt/decrypt your Ubuntu One folder, there is a simpler way to do.

The Ubuntu One Encrypt/Decrypt script is a simple Nautilus script that allows you to encrypt/decrypt your files and folder from the context menu. It is easy to use and doesn’t require any configuration.

Note: The script only works in Gnome Nautilus.

1. Download the Ubuntu One Encrypt/Decrypt script from Gnome-look

2. Save the script to the /home/username/.gnome2/nautilus-scripts folder.

3. Right click on the script and select Properties. Go to the Permission tab and check the box “Allow executing file as program”.

Press Alt + F2 and enter the follow command to restart Nautilus:

killall nautilus

4. Re-open Nautilus. Right click on any file/folder that you want to encrypt. Select “Scripts -> Ubuntu One Encrypt Decrypt script.sh”.

5. In the popup window, select “Encrypt”.

6. It will then prompt you to enter a strong passphrase.

Once it’s done, it will encrypt your file/folder and move it to your Ubuntu One folder. If it is a folder, it will first compress it before the encryption. This is what you will see in your Ubuntu One folder after the encryption.

To decrypt a file/folder, you have to first copy the encrypted file/folder from the Ubuntu One folder and paste it to another location (the script won’t work within the Ubuntu One folder). Right click on the encrypted file/folder and select “Scripts -> Ubuntu One Encrypt Decrypt script.sh”. This time, select Decrypt.

Once authenticated, the script will proceed to decrypt the file. If it is a folder, the script will untar the compressed file and restore the actual folder.

Advantages

1. Easy to use.

2. Good for storing backup of files/folders that you seldom use.

Disadvantages

1. It is not dynamic. You have to encrypt/decrypt the file/folder every time you want to access it.

2. It doesn’t sync your file/folder. You have to repeat the same process again every time you add/remove files to/from a folder or make changes to a file.

Note: This script will work for Dropbox as well. You just have to open the script in a text-editor and change every instance of “Ubuntu One” to “Dropbox” (assuming your dropbox folder is /home/username/Dropbox). Your encrypted file will then be saved to the Dropbox folder.
