The USB drive is a device that is used by almost everyone today. However, there's a downside…

USB sticks are easily lost or stolen.
Aren’t they?

Yes, it is easy to create an encrypted USB drive in Ubuntu so that, at least you could rest easy after the loss of a USB drive knowing that your data is secure.
So without wasting much of your time, let’s get to know how to create an encrypted USB drive in Ubuntu.
Getting Ready
Before you can actually encrypt your USB flash drive in Ubuntu, you need to install the cryptsetup utility on your Linux system, which could be easily done by executing the following command:
-sudo apt-get install -y cryptsetup
Once installed, insert the USB flash drive you’d like to encrypt into your computer, but make sure that everything that is on the drive is backed up!
Because, the encryption process requires your USB flash drive to be wiped, and anything currently on it will be lost if the drive is not backed up!
Encrypting the USB drive
Once you made sure that your drive’s contents are backed up, plug in your USB drive and open Disk Utility from the Dash.
Now, select your flash drive from the list on the left side and click on either the Stop button or Unmount partition icon present just below the highlighted partition.
Next, click on the Gears icon present in the same line and then choose “Format”. You will get the following window:
You can choose either quick or slow Erase options (although slow erase is technically safer), and then make sure to choose “Encrypted, compatible with Linux systems (LUKS +Ext4)” in Type.
Further, you can type a name for the flash drive in the Name field, set a password of your choice for it and click on Format.
The format process may take some time depending on your selection of Erase option. Once completed, pull your USB flash drive out and re-insert again. You will see the following prompt:
Congratulations, you have successfully encrypted your USB flash drive.
Now every time you plug your USB flash drive into a Linux system, it will ask a password to get unlocked, allowing you to use it just as easily as before.
Now if you lose your flash drive, your content is safe as no one will be able to access it without running Linux and knowing your secure passphrase.
