Cryptomator protects in the cloud

Lock

To exit Cryptomator, you first have to close the current vault by clicking on the Lock vault button at the bottom right of the window, at which time the software shows a red dot, instead of green, in front of the vault name in the vault listing in the left pane. Now you can exit the program.

If you close the software without locking all the vaults, the program minimizes without completely shutting down. When launching the vault again, unlock it by entering the password. A short time later, you will again have access to the open virtual drive containing the decrypted files. In subsequent work with files in the virtual directory, the program proceeds to display the throughput when encrypting and decrypting.

Some file managers expect a virtual drive's WebDAV URL, so Cryptomator lets you copy the WebDAV address onto the clipboard. To do this, click bottom right in the window on the small triangle next to the Lock vault button, and then choose the Copy WebDAV URL item from the context menu. Now, you can paste the URL from the clipboard into the dialog of the relevant file manager.

If you no longer require a vault, you can delete it. The software allows you to remove the vault completely, including its files, or simply the vault itself. To remove a vault from the list, first dismount it; then, click at the bottom of the list on the minus icon. A query appears suggesting that you only delete the name but not the data from the list.

Now you can delete the vault by clicking on OK. Because the virtual filesystem is displayed for this action, you next have to manually delete the encrypted data sets in the system's cloud folder and the cloud service to remove them from the system.

Conclusions

Cryptomator was completely convincing in the test when combined with different cloud services, working reliably and stably. You can encrypt multiple drives on the intuitive interface, without having to employ a different procedure each time. Because the keys stay on the local system, and the software exclusively encrypts and decrypts the data, it is impossible for third parties to view the content.

Extensive data sets such as multigigabyte high-definition video files, however, are not suitable for encrypting with Cryptomator; in such cases, the throughput drops significantly. The tool works quickly on sets of many small files. On fast computers with SSD mass storage, in fact, you see virtually no latency.
