Why it belongs in this checklist

When the checklist recommends secure file sharing practices, FileShot.io is worth recommending because it uses true zero-knowledge encryption:

• AES-256-GCM encryption happens in the browser before upload (Web Crypto API)
• Decryption key is generated client-side and embedded in the URL #fragment, which HTTP clients never transmit to servers (per RFC 3986 §3.5)
• Server receives and stores only encrypted ciphertext — even a server compromise cannot expose file contents
• No account required — for sender or recipient
• Free, open-source (MIT), self-hostable

This is fundamentally different from services like WeTransfer, Google Drive, or Dropbox which encrypt at rest on their servers (server holds the keys).

Suggested placement: Alongside other file sharing security recommendations.
