HEX BLADE PHP/MySQL key server

1. Create MySQL database/user in phpMyAdmin.
2. Edit config.php DB_* values.
3. Open /install.php once, then DELETE install.php.
4. Admin: /admin/login.php
   Root username: Nguyen
   Initial password: hacklo123@
   Change it after first login (recommended: via DB password_hash or add change-password page).
5. Client API: /api/hex.php?key=KEY&device_id=DEVICE
6. Auto cleanup: panel/API already call cleanup. Optional cron: php cron/cleanup.php every 5 minutes.

IMPORTANT COMPATIBILITY NOTE:
The APK endpoint/query has been statically confirmed, but the exact response encryption key/schema has NOT been fully proven from the binary. Default API_RESPONSE_MODE=json is intentionally honest/testable. Switch to base64_xor only after the client's XOR key is independently verified, then set API_XOR_KEY.

Server domain: https://hexbladecrack.duckdns.org
Key API: https://hexbladecrack.duckdns.org/api/hex.php?key=<KEY>&device_id=<DEVICE_ID>
