Cryptomator
What is Cryptomator?
Cryptomator is a free application that allows you to easily and conveniently encrypt data and store it securely locally, on a network drive or in the cloud. You can find out how to encrypt data using Cryptomator in the following instructions.
What you need to consider
- You need administrator rights on your computer for the installation. If you do not have this, please contact your IT administrator.
- If you want to share a folder encrypted with Cryptomator with someone, this person must also have Cryptomator installed on their computer in order to be able to open the encrypted folder.
- When using a shared encrypted folder (e.g. in HessenBox), it is not possible to work on the files stored there at the same time.
- Even if you use the secure AES-256 encryption method, the file is only as secure as your password allows it to be. Keep this in mind when choosing your password! You can find tips on creating secure passwords on our password security page.
- It is possible to create a recovery key. If you forget the password, this key is the only way to regain access to your encrypted data. It is important that you keep this key safe and inaccessible to third parties.

Create a new safe
Step 1: Add a safe
If not already done, start the Cryptomator.
Select “Add” and “New safe ...”.

Step 5: Set password
You must then enter a password for your safe. Choose a secure password with at least 12 characters. You can find tips on creating secure passwords on our password security page.
You also have the option of creating a recovery key. If you forget your password, this key is the only way to decrypt your safe again.

Step 6: Recovery key
Print out the recovery key or copy it into a password manager or onto a USB stick, for example. The key must not be accessible to third parties; in particular, the key must not be kept together with the encrypted safe.
