🔒 ATLOCK v4.0 — Total Security Suite
A major update focused on stronger security, cleaner architecture, and simplified alerting.
✨ What's New in v4.0
- Hardened Password Vault — Migrated from weak encoding to real AES encryption (Fernet) with PBKDF2-HMAC-SHA256 key derivation (200,000 iterations) for the master password
- NTFS ACL File Guard — True OS-level file locking using Windows Access Control Lists, not just a password prompt
- Intruder Detection — Auto-captures a photo on the 1st wrong attempt, and a 10-second video on repeated/critical attempts, with masked (never plaintext) attempt logging
- System Lockdown — Countdown-based screen lock with OS-level hardening
- Redesigned Settings Panel — Cleaner toggles for capture, sound, and gallery management
