-------------------------------
Основные характеристики:

Безопасность:

• Использование pathlib для кроссплатформенности.
• Шифрование данных перед записью на диск.
• Гибкая настройка путей через класс SecurePaths.

Оптимизация:

• Контекстные менеджеры (с) для работы с файлами и базами данных.
• Сжатие всех данных в один ZIP-архив с помощью AES-256.

Скрытность:

• Маскировка в папке .cache_update.
• Возможность интеграции с TOR (заглушка в Exfiltrator).

Обработка ошибок:

• Регистрация ошибок без сбоя скрипта.
