Multi-platform transparent client-side encryption of your files in the cloud. 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 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. 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.
