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.

Blog - Cryptomator
Downloads - Cryptomator
GitHub - cryptomator/cryptomator: Multi-platform transparent client-side encryption of your files in the cloud

  • Works with Dropbox, Google Drive, OneDrive, ownCloud, Nextcloud and any other cloud storage service which synchronizes with a local directory
  • Open Source means: No backdoors, control is better than trust
  • Client-side: No accounts, no data shared with any online service
  • Totally transparent: Just work on the virtual drive as if it were a USB flash drive
  • AES encryption with 256-bit key length
  • File names get encrypted
  • Folder structure gets obfuscated
  • Use as many vaults in your Dropbox as you want, each having individual passwords
  • One thousand commits for the security of your data!
  • 256-bit keys (unlimited strength policy bundled with native binaries)
  • Scrypt key derivation
  • Cryptographically secure random numbers for salts, IVs and the masterkey of course
  • Sensitive data is wiped from the heap asap
  • Lightweight: Complexity kills security
  • HMAC over file contents to recognize changed ciphertext before decryption
  • I/O operations are transactional and atomic, if the filesystems support it
  • Each file contains all information needed for decryption (except for the key of course), no common metadata means no SPOF

2018 Roadmap for Cryptomator
Since it is understandable that not all of our users can track all development activities on GitHub, I would like to write a few paragraphs here about the technical updates that are planned for Cryptomator in 2018 and their impact on usage
  • FUSE-based drives, in addition to WebDAV
  • Java 9 - better HiDPI support, rapid release and smaller installed state
  • IntelliJ
  • 64-bit
