🛠️ Tools Included

1. ⚙️ Port Scanners

Custom-built scripts to identify open ports on a target system.

Script	Language	Platform	Description
portscan.ps1	PowerShell	Windows	A basic TCP port scanner using native PowerShell commands. Designed for quick scans in Windows environments.
portscan.sh	Bash	Linux/macOS	Bash-based TCP scanner using /dev/tcp or nc. Lightweight and portable.
portscan_pwsh.ps1	PowerShell (Core)	Kali Linux (pwsh)	A PowerShell Core-compatible port scanner for use on Kali or any Linux distro with pwsh.

Each script allows basic configuration (IP, port range) and outputs open ports in a readable format.

📝 Notes

Scripts are kept intentionally minimal for learning and extensibility.
The port scanner is not meant to replace nmap or nc
Tested on Windows 10, Kali Linux (2025.2), and Ubuntu 22.04 with PowerShell Core.
Contributions or suggestions welcome as I continue learning and refining.
