## Description

KyberVault is a post-quantum cryptographic toolkit that generates, stores, and manages encryption keys entirely on your device. No accounts. No cloud. No network permissions. Your keys never leave your phone.<br><br>WHY POST-QUANTUM?<br>Today&#39;s encryption (RSA, ECDH) will be broken by quantum computers. KyberVault uses Kyber-1024 — the NIST-standardized post-quantum algorithm — combined with classical X25519 in a hybrid mode, protecting your data against both current and future threats.<br><br>FEATURES<br><br>Key Generation — Kyber-1024 (ML-KEM), X25519, hybrid mode, and AES-256-GCM session keys.<br><br>Key Storage — RAM-only by default. Optional encrypted persistence via Android Keystore with AES-256-GCM. Named aliases with save/load/wipe controls.<br><br>Key Exchange — Full KEM workflow. Import recipient keys via paste or QR scan. Generate and exchange encrypted session keys. Wire format for compact sharing.<br><br>Encrypted Messaging — AES-256-GCM authenticated encryption with session keys. Copy, share, or QR any output.<br><br>SECURITY<br>Three independent auth methods: biometric fingerprint, TOTP 2FA (Google Authenticator/Authy), and PIN lock. Screenshot protection, root/debugger detection, cloud backup disabled, no INTERNET permission, log stripping, and ProGuard obfuscation.<br><br>13 languages. OpenDyslexic font option. Material 3 dark theme.<br><br>Free, open-source, and auditable on GitHub. No analytics. No ads. No telemetry. Built for a post-quantum future.
