Introduction to VeraCrypt

VeraCrypt is a disk encryption tool that works on Windows, macOS, and Linux.

Comparison between LUKS and VeraCrypt

You can also create and open LUKS encrypted volumes in Tails. LUKS is the standard for disk encryption in Linux. See our documentation about LUKS.

We recommend that you use:

• VeraCrypt to share encrypted files across different operating systems.

• LUKS to encrypt files for Tails and Linux.

1. See the difference between file containers and partitions.

2. Plausible deniability: in some cases (for example, with VeraCrypt hidden volumes), it is impossible for an adversary to technically prove the existence of an encrypted volume.

   Still, deniable encryption might not protect you if you are forced to reveal the existence of the encrypted volume. See VeraCrypt: Plausible Deniability.

To create new VeraCrypt volumes, do so outside of Tails. See the step-by-step guides by Security-in-a-Box on VeraCrypt for Windows.

Difference between file containers and partitions

With VeraCrypt you can store your files encrypted in two different kinds of volumes:

File containers

A file container is a single big file inside which you can store several files encrypted, a bit like a ZIP file.

Partitions or drives

Usually, drives (USB sticks and hard disks) have a single partition of their entire size. This way, you can encrypt a whole USB stick, for example. But, drives can also be split into several partitions.

Unlocking parameters

To unlock a VeraCrypt volume, you might need the following parameters, depending on the options that were selected when the volume was created:

• Passphrase

• Keyfiles: instead of or in addition to the passphrase, a VeraCrypt volume can be unlocked using a particular file or set of files.

  See the VeraCrypt documentation on keyfiles.

• PIM: a number that is needed if it was specified when creating the VeraCrypt volume.

  See the VeraCrypt documentation on PIM.

• Hidden volume: if you want to unlock the hidden volume inside the VeraCrypt volume.

  See the VeraCrypt documentation on hidden volumes.

• System volume: if you want to unlock an encrypted Windows system partition.

  See the VeraCrypt documentation on encrypting a Windows system partition.

Using a file container

Unlocking a file container without keyfiles

1. Choose Applications ▸ Utilities ▸ Unlock VeraCrypt Volumes.

2. Click Add and choose the file container that you want to unlock.

3. Enter the parameters to unlock the volume. For more information, see the Unlocking parameters section above.

4. Click Unlock.

   Unlock VeraCrypt Volumes unlocks your volume.

   If unlocking the volume fails (for example, if you mistyped the password), click on Unlock to try unlocking again.

5. Click Open to open the volume in the Files browser.

Unlocking a file container with keyfiles

1. Choose Applications ▸ Utilities ▸ Disks to start the Disks utility.

2. Choose  ▸ Attach Disk Image… from the top navigation bar.

3. In the Select Disk Image to Attach dialog:

   • Unselect the Set up read-only loop device check box in the bottom-left corner if you want to modify the content of the file container.

     

   • Choose All Files in the file filter in the bottom-right corner.

     

   • Navigate to the folder containing the file container that you want to open.

   • Select the file container and click Attach.

   An authentication dialog appears.

   

4. Enter the parameters to unlock the volume. For more information, see the Unlocking parameters section above.

5. Click Unlock.

6. Open your VeraCrypt volumes from the Places menu.

Using a partition or drive

Unlocking a partition on an external storage device

1. Plug in the USB stick or hard disk that you want to unlock.

   An authentication dialog appears.

   

2. Enter the parameters to unlock the volume. For more information, see the Unlocking parameters section above.

3. Click Unlock.

4. Open your VeraCrypt volumes from the Places menu.

Unlocking a partition on an internal hard disk

1. When starting Tails, set up an administration password.

2. Choose Applications ▸ Utilities ▸ Disks to start the Disks utility.

3. In the left pane, select the drive that corresponds to your hard disk.

4. In the right pane, select the partition that corresponds to your VeraCrypt volume.

   It should have an Encrypted? label.

5. Click the button in the right pane.

   An authentication dialog appears.

6. Enter the parameters to unlock the volume. For more information, see the Unlocking parameters section above.

7. Click Unlock.

8. Select the file system that appears below the unlocked volume.

9. Click the button to mount the volume.

10. Click on the /media/amnesia/ link in the right pane to open the volume in the Files browser.

Ejecting a VeraCrypt volume

1. Choose Applications ▸ Files to open the Files browser.

2. In the sidebar of the Files browser, click on the button on the label of your VeraCrypt volume.
