Key Exchange Architecture
Pike executes a hybrid post-quantum key exchange combining X25519 elliptic-curve Diffie-Hellman with Kyber-768 (ML-KEM) lattice-based cryptography, protecting against current interception and future quantum decryption.
Symmetric Stream Cipher
Symmetric payload encryption uses ChaCha20-Poly1305 AEAD with unique per-chunk nonces derived via BLAKE3 key derivation function, guaranteeing confidentiality and integrity.
Short Authentication String (SAS)
To eliminate active Man-in-the-Middle (MITM) attacks, both peers render a 6-digit Short Authentication String derived from the mutual key exchange transcript for out-of-band verification.
Ephemereal WebRTC Signaling
Signaling uses short-lived ephemeral key exchanges on Cloudflare Workers. SDP offers and ICE candidates are stored in volatile memory and purged immediately upon connection establishment.
