Ubuntu: How to encrypt individual folders?


Let's say that I have a folder, within my Documents folder, that has files I want no one to access without a password.

Is there a way to lock down that folder so that it's password protected / encrypted?

In fact, is it possible to password-protect any individual folder?

You have 2 choices if you want to lock down a folder from other users

  • Encrypt or create a compressed password protect archive of the files. The methods in https://askubuntu.com/a/104545/25863 and https://askubuntu.com/a/104984/25863 are perfect for this case when you need to be 100% sure no one will ever look at your files without knowing the password used there.

  • Use your computer folder / file permissions to deny access to your folder to other user.

The fist involves making sure that the result cannot be opened by any user without knowing the password used.

The second will only change the file / folder privileges so that another user without rights cannot open it. The folder still exists, can be accessed by any user with sudo rights in your system or using a LiveCD and reading the partition. It is also simpler to implement and does not require that you type a password all the time you need to open / mount the encrypted folder / archive.

An easy and fast way to do so is using chmod to change the privileges for a file or folder.

Open a terminal and navigate to the place where your folder is, lets assume that the folder name is foo and that we are currently located where the folder is.

chmod 700 foo  

will make foo only available for your eyes, its not encrypted (that is also possible) but only your user (and or a user with sudo privileges) can read or open that file / folder.

You can also do it graphically by right clicking on a file or folder and changing its permissions manually. In the example bellow you as owner have all privileges and you deny any other group or user from accessing, reading or modifying that file / folder

For more information about file / folder permissions visit the Ubuntu Understanding and Using File Permissions wiki page.


Search for and install ‘ecryptfs-utils’ in Ubuntu Software Center:

enter image description here

After installing, go to Applications â€"> Accessories â€"> Terminal and run the command below:


enter image description here

You’ll be prompted to type your login passphrase (password), and to create one for your private folder:

enter image description here

When you’re done creating your password, Log Out and Log back in:

enter image description here

Next, go to Places â€"> Home Folder:

enter image description here

And new folder should be created in your home directory called ‘Private’. This folder in encrypted and password-protected. Move all your personal stuff into this folder to secure them:

Users without access to the folder will be denied:

You can try Vault, recent project by an ubuntu-gr member (greek local community): http://clepto.github.com/ - https://github.com/Clepto/Vault

PPA: https://launchpad.net/~vault/+archive/ppa

sudo add-apt-repository ppa:vault/ppa  sudo apt-get update  sudo apt-get install vault  

It's a gui utility for encfs (package in repositories). I quote the package description:

$ apt-cache show encfs  Package: encfs  [...]  Description-en: encrypted virtual filesystem   EncFS integrates file system encryption into the Unix(TM) file system.   Encrypted data is stored within the native file system, thus no   fixed-size loopback image is required.   .   EncFS uses the FUSE kernel driver and library as a backend.  Homepage: http://www.arg0.net/encfs  

You create a mountpoint/folder which you can then close or delete. If you close it, you need a password to open it.

Another way, depending on your needs is to archive the folder as a password protected zip file.

This is similar to another question about password protecting files.
