Here’s why that matters. **[All Things Open](https://daily.dev/sources/allthingsopen)** · 9 min read · 0 upvotes · 0 comments ## Summary Most cloud storage providers encrypt data with keys they control, meaning they can decrypt your files on demand — for legal requests, breaches, or internal access. End-to-end encryption (E2EE) keeps keys on your device so the server only ever stores unreadable ciphertext. The post clarifies the difference between encryption in transit, at rest, and true E2EE; explains why open source client code is essential for verifying cryptographic claims; highlights Proton Drive and Nextcloud as practical examples; and outlines what to check when evaluating an E2EE solution: client-side key generation, zero-knowledge architecture, auditable code, key recovery model, and metadata handling. ## Full article daily.dev links to this article rather than hosting it.
