Secure message sharing
Messages are encrypted in your browser with a fresh AES-256-GCM key, locked to the recipient’s public key, and delivered through the cloud to their device.
Messages sent to you appear in the Messages section below. They are decrypted only on this device, after you sign in with your passkey.
No message opened.

!Cloud messagingMessages sync between devices through Supabase. Passkeys remain a browser-side sign-in gate; the cloud does not verify them.
01What is simulated?Small-scale boson sampling using explicit matrix permanents.
02How are messages protected?A fresh AES-256-GCM key encrypts each message and is wrapped with the recipient’s RSA public key. The cloud never sees plaintext or usable keys.
03Security noteThe Boson Sampling display is educational and does not provide quantum-secure key exchange.
