From 2110adaefd972f4d19774588cd2d077b0e4076d8 Mon Sep 17 00:00:00 2001 From: Anh Nguyen Date: Thu, 21 Aug 2025 17:38:30 +0700 Subject: [PATCH 1/5] feat: implement milestone M1 - device identity & pairing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add comprehensive ECDH key generation and device identity derivation - Implement QR code generation and parsing for device pairing - Add safety words fingerprint verification system using BIP-39 subset - Create QR scanner with BarcodeDetector API and fallback library - Build device management with localStorage persistence - Add React components for QR display and scanning UI - Include comprehensive test coverage (68/68 tests passing) -
