Show HN: N0vaTools – A cool toolkit with many features

N0vaTools is a Windows-based terminal utility written in Python. It includes a stylized menu system, an interactive "Hacking Terminal" shell, built-in app installers (e.g., Java), and a self-update feature using GitHub Releases.

• Download the latest release here!

• 🎯 Arrow-Key Menu Navigation with Color Output
• 🔐 Password Protection (Default: hack1ng)
• 🔄 Auto-Updater that checks for the latest executable via GitHub
• 💻 Custom Command-Line Shell (Hacking Terminal) with:
  • Windows-style prompt
  • Built-in cd, mkdir, scan, portscan, and colour commands
  • Command output with dynamic ANSI color wrapping
• ☕ Java 21 Installer with PATH auto-updating

1. Run the compiled EXE

   Unfortunately, running the uncompiled script will not work due to the auto-updating system.

   The script prompts for a password (hack1ng) before proceeding.

2. Navigate the menu using ↑ ↓ and select with Enter.

3. Available menu options:

   • Install apps → Install Java 21
   • UEN v1 → Coming Soon
   • Hacking Terminal → Launch interactive shell
   • Quit → Exit N0vaTools

• cd [dir] — Change directory (only within ~/hacking-terminal)
• mkdir <name> — Make a new directory
• scan <name> — Scans your local network for devices whose hostnames contain <name>.
• portscan <ip> — Scans an IP or URL for open ports in the 1-65535 range.
• colour <name> — Change prompt/output color
  Available colors: red, orange, yellow, green, blue, purple, pink, white, black, grey, default
• exit / quit — Exit terminal

If a newer N0vaTools.exe is published on the linked GitHub repository, the app will:

• Download the EXE to a temp location
• Verify it with SHA256
• Replace the running executable with the new one
• Restart automatically

GitHub Release API endpoint:

Downloads Java 21 from Oracle, extracts it to %userprofile%\Java21, and adds it to the system Path via the Windows Registry.

• This is Windows-only due to msvcrt, winreg, and ctypes.windll usage
