Secure Web Server Fingerprinting Tool

Overview

This project is a web server fingerprinting system that detects the server type and version of target websites using HTTP/HTTPS banner grabbing.

It includes:

• Terminal-based client
• React frontend (fingerprint-ui)
• Secure Python backend using sockets and SSL

---

Architecture

React Frontend (fingerprint-ui) | v Python Secure Server (Socket + SSL) | v Target Websites (HTTP / HTTPS)

---

Features

• SSL-secured communication
• Multi-threaded server
• HTTP & HTTPS scanning
• Server detection (Apache, Nginx, IIS, etc.)
• Version extraction using regex
• Terminal + Web interface

---

Technologies Used

Frontend: React (fingerprint-ui) Backend: Python Networking: Socket Programming Security: SSL/TLS Concurrency: Multithreading

How It Works

Terminal Flow:

1. User enters URL
2. Client sends via socket
3. Server scans
4. Result displayed

Web Flow:

1. User enters URL in UI
2. Request sent to backend
3. Server scans
4. Result shown in UI

---

Data Flow

1. Input from user
2. Request sent to server
3. SSL connection established
4. Server performs scan
5. Headers extracted
6. Server + version detected
7. Response sent back
8. Output displayed

---

🧪 Sample Output

Enter target website: example.com

[+] Scanning...

Target : example.com Protocol : HTTPS Server : Nginx Version : 1.18.0

---

Setup & Run

1. Generate SSL Certificate openssl req -new -x509 -days 365 -nodes -out cert.pem -keyout key.pem

2. Start Server python3 server.py

3. Run Terminal Client python3 client.py

4. Run React Frontend cd fingerprint-ui npm install npm start

Key Concepts

Socket Programming: socket.socket() connect() send() recv()

SSL Encryption: ssl.wrap_socket()

Multithreading: threading.Thread()

Banner Grabbing: HEAD / HTTP/1.1
