Why Choose This Project?

Every secure website uses SSL/TLS certificates to encrypt communication between users and servers. These certificates expire periodically and must be renewed on time. Failure to do so leads to browser warnings, loss of user trust, and potential downtime. This project automates the process of checking SSL certificate expiry dates and notifies stakeholders well in advance.

It’s a highly useful DevSecOps utility, easy to demonstrate and sell, and perfect for real-world implementation in IT and cybersecurity environments.

What You Get in This Project

• An intelligent SSL/TLS certificate scanner tool

• Automatic checking of expiry dates for any domain

• User-friendly dashboard to manage domain list

• Notifications via email or SMS when expiry is near

• Schedule-based auto-check (daily, weekly, etc.)

• Visual indicators for certificate status (safe/expiring/expired)

• Domain health report export to PDF or CSV

• Full-stack working solution with installation guide

Technology Stack

How It Works

1. Domain Input Panel
   Users can input one or more domain names (e.g., example.com, sub.domain.org) into the dashboard.

2. SSL Check Logic
   The backend fetches the SSL certificate of each domain using standard libraries:

   • Python: ssl and socket modules

   • Node.js: tls and https modules

   • Java: SSLSocketFactory with X509Certificate

3. Expiry Date Extraction
   It parses the notAfter field from the certificate and calculates:

   • Days left until expiry

   • Whether it's safe (>30 days), warning (<30 days), or critical (<7 days)

4. Automated Scheduling
   The tool runs daily or weekly (configurable) and checks all domains in the database.

5. Notifications
   Sends alerts via email/SMS if any domain is:

   • Expiring soon

   • Already expired

6. Dashboard Display
   All domains are listed with:

   • Domain name

   • Certificate issuer

   • Expiry date

   • Status badge (Green/Orange/Red)

7. Reports
   Option to export all SSL health reports to PDF or CSV for compliance or audits.
