Original: Zero-Knowledge Architecture: What It Means for Your Files

Short summary

Zero-Knowledge Architecture ensures files are encrypted client-side with keys never held by servers, making data useless to attackers even if the service is breached. Distinguish it from traditional encryption (where providers hold keys) and E2EE (which doesn't guarantee provider zero-knowledge). Evaluate services by checking for client-side encryption, URL-fragment key sharing, and published threat models.

  • Encryption happens on your device; server never sees decryption keys
  • Breached data remains encrypted without key access to attackers
  • Verify implementation: check client-side encryption, key handling, and threat models

Generated with AI, which can make mistakes.
