Full web client with E2E encrypted messaging
Complete single-page web app served at / with: - Identity generation (random 32-byte seed) - Identity recovery from hex seed - Persistent keys in localStorage (survives refresh) - Auto-load saved identity on page load - ECDH P-256 key exchange via Web Crypto API - AES-256-GCM message encryption (iv prepended) - Key registration with /v1/keys/register - Send encrypted messages via /v1/messages/send - Poll for messages every 2s with auto-decrypt - Peer fingerprint input in header (saved to localStorage) - Color-coded messages (green=self, orange=peer, cyan=system) - Lock icon on received encrypted messages - Commands: /info, /clear, /quit - Graceful handling of CLI client messages (shows warning) - Dark theme, responsive, mobile-friendly Note: web-to-web E2E works. Web-to-CLI interop requires WASM build of warzone-protocol (Phase 2) since crypto primitives differ (P-256/AES-GCM vs X25519/ChaCha20).
