VeraCrypt, an open source tool available on all major operating systems, is well-suited to meet the data encryption needs of virtually any media team.
Before following the step-by-step instructions in this guide, check out our general introduction to encryption for media makers for pro-tips and a technical glossary.

VeraCrypt is an open source volume management tool compatible with macOS, Windows, and Linux systems.
If you’re not already a VeraCrypt user, download the software from the developer’s website. Just like a physical signature, the developer leaves files that only they can sign using cryptographic keys on their website. To ensure we have a legitimate installation file (and not one that’s been tampered with) we should confirm that these files correspond to their encryption keys and signatures. It's easier than it sounds. Learn how in this guide from Freedom of the Press Foundation.
Because it is available on all major operating systems (macOS, Linux, and Windows), VeraCrypt is an ideal tool for teams geared towards cross-platform sharing (e.g. sharing encrypted storage in a mixed team of macOS and Windows users).
MacOS users listen up — If your team is composed entirely of macOS users, you don’t have to worry about sharing across different operating systems and can stick with Disk Utility, which is already installed on your device. You can refer to our Disk Utility guide to get started.
If you are a macOS user concerned about cross-platform sharing, or have otherwise decided to use VeraCrypt, you’ll have to install one dependency before you can start using it. Download and install an additional piece of software, OSXFuse, in order to manage some file formats in VeraCrypt that aren’t natively supported in macOS.
Let’s imagine that we are starting work on a feature-length documentary film. We will be capturing footage for the next couple of years for the project. Some of this footage contains first person interviews with sensitive sources. We want to take extreme care to make multiple copies, or backups, of this integral footage. Likewise, we want to protect our source with added technical safeguards placed on the backup hard drives.
Your solution? Creating encrypted external storage for medium- to long-term storage
During every stage of a film project, there remains unused footage, cuts, and other material that requires safekeeping. For some film teams, the risk of confiscation of storage devices is extremely likely while shooting in the field. When we encrypt storage media, we are protecting the data it will hold, erecting barriers that make it difficult and costly for unwanted third parties to access.
When you start up Veracrypt, you will be greeted by the Veracrypt volume manager, your one-stop-shop to mount, manage, and unmount up to twenty local and external VeraCrypt volumes.
We’ll circle back to managing your volumes at the end of the demo, but for now let’s hit the Create Volume option.
Create an encrypted file container: This option will guide you through the creation of an encrypted file container. You can think of it like a password-protected folder for sensitive files. It can either live on your computer as a repository for files in active projects, or you might want to send the file container to a collaborator, or store it on a trusted cloud service.
Create a volume within a partition/drive: This option will guide you through the process of formatting entire external storage media drives, or even partitions of external storage media. Other applications of this feature are outside of the scope of this guide.
In this example, we’ll be formatting and encrypting a USB drive, so we’ll select Create a volume within a partition/drive.
The default is a Standard VeraCrypt volume, which will give you all the functionality you need to create encrypted places to store data for media projects.
The Hidden VeraCrypt volume allows you to place high-priority files in a volume configured to appear as free disk space.
A Hidden volume may be appropriate for use in a limited number of circumstances, but planning around these situations requires time, technical expertise, and a legal strategy. If you are interested in exploring applications for Hidden volumes, contact the Freedom of the Press Foundation training team.
Volume Location: When you select your target external drive in the Volume Options menu, ensure that you have selected the top-level device name so that you reformat the entire drive, and not just a partition within it. Don’t forget — Every time you format a drive, all the files inside of it will be lost. If you have data on the external storage device you intend to encrypt, make sure you move those files off for safekeeping. You can always move that data back to your drive after it has been formatted.
Encryption Options: Confirm your intended device doesn’t contain essential files, and go ahead with the default encryption options.
Encryption Options: Confirm your intended device doesn’t contain essential files, and go ahead with the default encryption options.Volume Password: As always, designate a long, unique passphrase for your drive. This is essential to protecting the media you will hold on this storage device.
Large Files: Assuming we are going to be working with large media files, we should choose our second option on the “Large Files” menu, for storage above 4GB. This choice will give you different formatting options than the default in order to preserve your larger media files. Other projects, say a backup of prospective scripts, might not require such a setup.
Format Options: Depending on which operating system you’re running VeraCrypt on, you’ll have different format options. For the purposes of this guide, we’ll want to use the exFAT format. Why? It can be read by all major operating systems, and can support large files.
Cross-Platform Support: This window serves to double-check that you have selected the best format option for your use of the drive. Windows and Linux users will see a different menu dialogue, but all users should rest assured that exFAT format will work for media projects on any operating system.
Volume Format: You’ve reached the final window in the Creation Wizard. Double-check that you’ve memorized your encryption password, or saved it in your password manager. Now you’re ready to hit Format, and wait as VeraCrypt does the rest of the work. To increase the randomness of the number generator running the encryption, move your mouse around the application window.
Once your external storage device is finished formatting, you’re brought back to the main VeraCrypt application menu. Let’s go ahead and mount your freshly encrypted drive and load some project files on it.
Important note for macOS users — When you insert a VeraCrypt volume into your device, you will see a notification (just like the one above) that the volume is not “readable” by the computer. Don’t worry. Hit Ignore on the notification. You’ll be able to read and write to your USB drive’s storage through the VeraCrypt volume manager.
Same goes for Windows — Windows will appear to give your USB drive the same letter as it had before (for example, A:\) but if you try to navigate to that drive letter in Explorer, you will see a notification asking if you’d like to format it. You should ignore this notification, since formatting will delete the encrypted VeraCrypt partition. You’ll be able to read and write to your USB drive’s storage after you use the VeraCrypt volume manager to mount it under a different drive letter (for example, D:\ instead of A:\).
When you've inserted your encrypted device and opened up the VeraCrypt volume manager, you're ready to proceed. Hit “Select Device” on the volume manager window and choose your storage device from the available options. Next, enter your device password.
With your encrypted VeraCrypt volume mounted, you can now access the drive through Finder. On this system, we’ll be working with a Finder window under “Devices.” We’ve added some project files for safekeeping. When you’re done, go ahead and “Dismount” the device from the VeraCrypt application window.
You might simply want to create an encrypted container you can throw onto a cloud service before travel. You might need to restrict local access to a set of files on a shared computer. You might want to compartmentalize project assets on your work device. You might want to take precautionary steps against data leakage during a superficial search of your unlocked device.
Your solution? Encrypting containers on your computer to safeguard files.
It might sound like overkill to create an encrypted image within your hard disk (assuming the hard disk is already fully encrypted, which it should be), but there are some novel ways a media maker might want to leverage this utility.
If you’d like to move files into an encrypted container using VeraCrypt, open up the application. In the volume manager window, select Create Volume.
The first window of the Volume Creation Wizard gives you two high-level options for creating VeraCrypt volumes. We’re considering creating a space to hold a few highly-sensitive files, so we’ll go ahead and select the Create an encrypted file container option.
Volume Type: Stick with the default option here, which is our Standard VeraCrypt volume.
Volume Location: This is where you designate where you’d initially like the file container saved. You can move it anywhere you like after it’s created, but for now we’ll save the container to Desktop with the name project.
Encryption Options: Stick with your defaults here. AES and SHA-512.
Volume Size: Your volume size will dictate the storage capacity of your file container. You can pick any size you’d like, so long as your computer or external device has the free space on its hard disk to host it! For our purposes, 5GB volume size will give us the space we need to store sensitive files like interview transcripts and source contacts.
Volume Password: Input your long, unique password. Double check that you’ve saved it somewhere secure before moving to the next step.
Large Files: This prompt asks about the size of files you plan to store in your file container. Because this solution won’t be tenable for larger files like video audio media, we will not be storing files over 4GB. Our container in this scenario is only 5GB, after all. Your choice will depend on the characteristics of your project.
Format Options: Select the FAT format option. This is the format you want for a volume under 32GB that will only handle smaller files. Note: If you're working with files over 4GB, VeraCrypt will recommend a different format, exFAT.
Volume Format: With your volume password saved or memorized, and after generating entropy through your mouse movements over the window, go ahead and hit the Format button. Wait for Verarypt to do its magic.
Return to your Volume Manager window to begin loading files into your new, encrypted file container.
Hit Select File and navigate to where you saved your file container. In our example, we’ve named the container project, and saved it to our Desktop. With our file container located, we’re ready to select Mount — input your passphrase and wait as the container is decrypted
With our file container now decrypted and mounted, we can begin adding files. We do this by opening up a Finder window, with our file container (NO NAME) showing up under Devices. In this example, we’re loading a backup of a few highly sensitive files for an upcoming project.
When we’re finished loading up our files, we can return to the VeraCrypt Volume Manager to encrypt our container. Highlight the volume name, and simply click on the Dismount button on the lower right-hand side of the window. And with that, you’re done!
