LATEST RELEASE September 24, 2026

v1.0.0 — Post-Quantum Production Release

The first major public release of Entangl, introducing the production-grade hybrid post-quantum ratchet, Tor arti hidden services, and mutual physical QR pairing.

Core Additions & Features

  • Mutual Dynamic QR Handshake: Two-stage visual challenge/response protocol with signed CBOR payloads, rolling nonces, and TTL expiration.
  • Post-Quantum Key Exchange (PQXDH): Combined ML-KEM-768 (Kyber-768) + X25519 ratcheting via libsignal-client to protect against Store-Now-Decrypt-Later attacks.
  • Decentralized Tor Routing: Embedded lightweight Tor arti daemon running private v3 .onion hidden services directly on Android.
  • Local Wi-Fi P2P: Sub-millisecond direct socket messaging when peers are connected to the same LAN.
  • Hardware Keystore Vault: Local SQLite storage encrypted with SQLCipher (AES-256) and anchored into hardware StrongBox.
  • Cyber Color Picker: Live HSV profile color customizer with Ed25519 digital signature binding.
  • Zero-Leak Notifications: NotificationCompat.VISIBILITY_SECRET preventing sensitive lockscreen preview exposures.
  • Anti-Forensic Controls: FLAG_SECURE, NativeKeyBuffer with sodium_memzero() on ephemeral state, and tapjacking guards.
