go4crt.sh

go4crt.sh is a small, blazing-fast subdomain enumeration utility that pulls certificate transparency records from crt.sh and turns them into a clean, deduplicated list of subdomains—ready for live checking, screenshotting, fuzzing, or any next-step recon. I built it to give pentesters and bug bounty hunters a minimal, reliable tool that does one thing very well: extract subdomains from public TLS certificates and save them to a file so you can plug the results straight into your workflow.

✨ Features

• 🔍 Fetch subdomains from crt.sh Certificate Transparency logs
• 📂 Save results in a text file
• ⚡ Simple and fast (pure Go, no dependencies)

📦 Installation

go install github.com/4ncurze/go4crt.sh@latest

🚀 Usage

go4crt.sh -d example.com -o subdomains.txt
