Cloud is encrypted


Cryptomator encrypts everything you put into the drive on-the-fly. Your cloud is now secure.

The Concept of Cryptomator

Cryptomator provides transparent, client-side encryption for your cloud. Protect your documents from unauthorized access. Cryptomator is free and open source software, so you can rest assured there are no backdoors.

Easy and Reliable

We understand simplicity as a key aspect of security. With Cryptomator you don't have to deal with accounts, key management, cloud access grants or cipher configurations. Just choose a password and you're ready to go.

You don't even need to specify what cloud you use. Cryptomator encrypts files and doesn't care where you store them. This makes it a lightweight application, which we believe is a huge benefit for reliability. Complexity would kill security.

Cryptomator is a so-called transparent encryption utility. This means that you don't have to learn new workflows. Just work with your files as you're used to.

Secure and Trustworthy

Cryptomator encrypts file contents and names using AES. Your passphrase is protected against bruteforcing attempts using scrypt. Directory structures get obfuscated. The only thing which cannot be encrypted without breaking your cloud synchronization is the modification date of your files.

Cryptomator is a free and open source software licensed under the GPLv3. This allows anyone to check our code. It is impossible to introduce backdoors for third parties. Also we cannot hide vulnerabilities. And the best thing is: There is no need to trust us, as you can control us!

Vendor lock-ins are impossible. Even if we decided to stop development: The source code is already cloned by hundreds of other developers. As you don't need an account, you will never stand in front of locked doors.

What users say

I use Cryptomator for encrypted areas inside my ownCloud and Seafile storage for private data. Without it I wouldn't be able to use the cloud to this extent.

Ulrich Zobel

I have really been missing an app with cross platform encryption for cloud services. This is by far the best.

Troels Bay

I've been incredibly impressed by your work on Cryptomator; I think you're going to help a lot of people!

This is the kind of app, the world has been waiting for!
