Multi-platform client-side encryption tool optimized for cloud storages
  4 reviews

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.

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.

Really like it and very handy (Nextcloud Sync etc.). But: Systray Icon is just a black square on Mint Cinnamon, Flatpak version doesn't support USB-drives and mounted partitions. Prefer the .deb file from github (mount works here). Keep up the good work.

I have just started to use it and it looks great, especially for the cloud storage where several solutions are expensive and does not guarantee a real encryption and privacy

Most people don't realize the power of this simple tool. Once you create a "vault", point your cloud sync service to the ENCRYPTED files on your hard drive, so they get synced on your favorite cloud service. *DO NOT SYNC YOUR UNENCRYPTED VIEW!!!!* You now have full end to end, zero knowledge encryption of your FREE CLOUD DRIVES! Whether or not you sync an encrypted volume to a cloud drive service, CryptoMator is great to use to create an encrypted volume for your work related files. If you use your personal computer for work for an employer, this lets you give confidence to your employer and your customers that you're protecting their proprietary and PII data AND if you leave the job, you just have 1 folder to delete. Make an encrypted volume on your work computer, sync it to a cloud drive, then sync it to your home computer, then open a decrypted view of it, and voila! You've got end to end encrypted file sharing between work and home, protecting you, your company, and your customer's data. I also use it for local backups of my password manager by exporting from it weekly into an encrypted vault.
