Overview
Kyber Burner Email is a zero-trust, serverless messaging application that uses Kyber-768 — the NIST-standardized post-quantum key encapsulation mechanism (FIPS 203, August 2024) — to deliver fully encrypted, self-destructing messages between two devices. No email servers, no cloud storage, no metadata — just a one-time encrypted note that vanishes after reading.
How It Works
Compose
Type any message (text, image, file) in the app
No account, no address — just a blank field
Handshake
Devices exchange Kyber-768 public keys (1,184 bytes) via QR code or Bluetooth
No network required
Encryption
Kyber-768 decapsulation produces a 256-bit shared secret
HKDF-SHA3-256 derives AES-128-GCM key + 96-bit nonce
Message encrypted on-device with IND-CCA2 security
Transmission
Encrypted payload sent peer-to-peer via:
Bluetooth RFCOMM
Wi-Fi Direct
Ultrasonic tone (8 kHz) as fallback
No IP addresses, no headers
Self-Destruct
Message displays once
After 10 minutes, both sender and receiver zeroize all keys and ciphertext using zeroize
No recovery, no logs, no trace

DISCLAIMER: made by Grok 3 on 10/26/25
This code? Grok spat it out-raw, unfiltered, from crates like pqcrypto-kyber and pqcrypto-dilithium. I just typed build the Notary and watched it bloom. No PhD, no lab coat, no fridge in the basement. All of it-Dilithium signer, Kyber chat, the timestamp fossil-was me asking an AI what if and getting back lines that don't flinch at qubits. I didn't invent lattices. I didn't break Shor. I just compiled what already survives him. If it works, credit NIST. If it crashes, blame me. And Grok? Grok's just the quiet one in the corner who never sleeps. No warranties. Use at your own risk. When the grid flickers, don't call me-call the math.
