How to Configure Ssl for Your Static Website Hosted on Github Pages Using Let's Encrypt

Securing your static website hosted on GitHub Pages is essential to protect your visitors and improve your site's trustworthiness. One effective way to do this is by configuring SSL (Secure Sockets Layer) using Let's Encrypt, a free certificate authority. This guide walks you through the process step-by-step.

Prerequisites

A GitHub account with access to your repository hosting the website
A custom domain name (optional but recommended)
Basic knowledge of DNS management
Access to a server or service that can act as a proxy (e.g., Cloudflare)

Step 1: Use a Custom Domain

While GitHub Pages provides a default github.io domain, configuring SSL is easier with a custom domain. Set up your domain's DNS records to point to GitHub Pages by creating an A record or CNAME record as per GitHub's instructions.

Step 2: Use a CDN or Proxy Service

GitHub Pages does not support HTTPS directly for custom domains. To enable SSL, you can use a CDN or proxy service like Cloudflare. Sign up for Cloudflare and add your domain. Cloudflare will act as an intermediary, providing SSL termination and security features.

Step 3: Configure Cloudflare for SSL

In Cloudflare, navigate to the SSL/TLS settings. Choose the 'Full' or 'Full (strict)' mode to ensure end-to-end encryption. Make sure your DNS records in Cloudflare point correctly to your GitHub Pages site.

Step 4: Enable Automatic HTTPS Rewrites

In Cloudflare's dashboard, go to the 'Edge Certificates' tab and enable 'Automatic HTTPS Rewrites.' This ensures that all HTTP links are redirected to HTTPS, providing a secure browsing experience.

Step 5: Test Your SSL Configuration

After configuration, visit your website using https://yourdomain.com. Use tools like SSL Labs' SSL Server Test to verify that your SSL certificate is correctly installed and your site is secure.

Conclusion

While GitHub Pages does not natively support SSL for custom domains, leveraging a CDN or proxy service like Cloudflare makes it straightforward to enable HTTPS using Let's Encrypt certificates. Following these steps ensures your static website is secure and trustworthy for your visitors.
