## Overview

This repository documents a hands-on Kali-to-Windows SSH administration lab, rather than implementing a runtime application. Its principal workflow is to generate an Ed25519 key pair on Kali, configure Windows OpenSSH and its firewall, test network and TCP/22 reachability, then authenticate and open a PowerShell session. The graph reflects the README’s documented steps; no source excerpts were provided, so relationships are based on that documentation only.
