## What it is
KnockPy is a modular Python 3 CLI tool for enumerating subdomains of a target domain using passive reconnaissance sources and DNS bruteforce, with async scanning via httpx. It validates HTTP/HTTPS status, TLS certificates, and IPs, detects wildcard DNS and legacy TLS, and stores results in SQLite with exportable reports.

## Use cases
- enumerate subdomains of a domain for a bug bounty recon
- bruteforce subdomains with a wordlist
- run passive subdomain discovery via VirusTotal and Shodan
- check AXFR zone transfer vulnerabilities on a domain
- detect wildcard DNS and legacy TLS 1.0/1.1 support
- export subdomain scan results to HTML or SQLite reports

## When to choose
- you need a fast async Python subdomain scanner for pentest or bug bounty recon
- you want passive recon plus bruteforce in one tool with SQLite reporting
- you need TLS, wildcard DNS, and AXFR checks during subdomain enumeration

## When to avoid
- you need a full vulnerability scanner rather than subdomain enumeration
- you require a GUI or web dashboard instead of a CLI
- you need non-DNS asset discovery like port scanning or screenshotting
