Feature suggestion: FileShot.io as a zero-knowledge encryption case study #126

Suggestion: FileShot.io

I would like to suggest FileShot.io as a real-world example of zero-knowledge client-side encryption — a topic highly relevant to security-conscious system design.

What it demonstrates

FileShot.io implements a clear, auditable zero-knowledge architecture:

• Client-side AES-256-GCM encryption using the browser Web Crypto API
• Key-as-URL-fragment pattern — decryption key lives in #fragment which browsers never send to servers
• Zero-knowledge server — stores only opaque ciphertext; cannot decrypt files even when compelled
• No authentication required — both sender and recipient are anonymous

Why it fits system-design-101

This list covers practical system design concepts with visual explanations. Zero-knowledge encryption and client-side security are increasingly important architectural patterns. FileShot.io is a minimal, readable, production implementation of these concepts.
