v1.8.10: security audit fixes
- --list and --status no longer expose IP/port/user (only aliases) - --list-full for admin use (not in skill) - Removed --add from /ssh skill (servers added via GUI only) - Removed exact file paths from skill template - Added deny-read rules for ~/.server-connections/ files - Wrapped main() in try/except to prevent traceback leaking - Added needs_reencrypt() to encryption.py for future migration - install_key no longer prints server IP Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

## ВАЖНО — Безопасность
|
||||
|
||||
- **НИКОГДА не читай** `D:\CODING\GitHub\.server-connections\servers.json` — там пароли
|
||||
- **НИКОГДА не читай файлы** в директории `~/.server-connections/` напрямую
|
||||
- **НИКОГДА не читай** файлы `encryption.py`, `servers.json`, `settings.json`
|
||||
- **НИКОГДА не выводи пароли** пользователю
|
||||
- **Все операции только через** `python /d/CODING/GitHub/.server-connections/ssh.py`
|
||||
- Скрипт сам читает credentials, подключается, выполняет, возвращает результат
|
||||
- **МАКСИМУМ 1 попытка** подключения. Если timeout/ошибка — сообщи, НЕ повторяй
|
||||
- fail2ban банит IP после 5-10 неудач — спам попытками УБЬЁТ доступ к серверу
|
||||
- **Серверы добавляются ТОЛЬКО через GUI** ServerManager, НЕ через CLI
