About:
CryFS is a cryptographic filesystem that encrypts files and stores them in a cloud-synced directory. It provides strong, client-side encryption without requiring a server, ensuring that only you can access your data. Unlike container-based solutions, it encrypts individual files, allowing for efficient syncing and better conflict resolution.
Key Features:
  • Client-side encryption for cloud storage
  • Individual file encryption for efficient syncing
  • FUSE-based filesystem integration
  • No server requirements
Use Cases:
  • Securely storing sensitive documents in Dropbox or iCloud
  • Backing up private data to untrusted cloud providers
  • Syncing encrypted configuration files across devices
Alternatives:
  • gocryptfs – Similar FUSE-based encrypted filesystem, but primarily designed for local storage rather than cloud optimization.
  • EncFS – Older encrypted filesystem; CryFS was designed to address security vulnerabilities found in EncFS.
