CryFS – cryptographic filesystem for the cloud

CryFS encrypts your files, so you can safely store them anywhere.

It works together with cloud services like Dropbox, iCloud, OneDrive and others. It should work well together with any cloud storage provider that uses a local synchronization folder.

CryFS is free and open source software.

Features include:

  • Easy to setup.
  • Uses scrypt for password hashing.
  • Uses GCM for encryption and integrity.
  • File size obfuscation.
  • File contents, metadata and directory structure are all secure from someone who hacked your cloud.
  • Cross-platform support – runs under Linux, Mac OS X, and there’s experimental support for Windows.
