Security
In today's web landscape, having an SSL certificate is no longer optional—it's essential. Not only does it secure data transmission between your server and users, but it also improves SEO rankings and builds trust with your audience.
SSL (Secure Sockets Layer) certificates encrypt data transmitted between a web server and a browser. This ensures that sensitive information like passwords, credit card numbers, and personal data remain private and secure from potential attackers.
Modern browsers like Chrome and Firefox now mark websites without SSL as "Not Secure," which can significantly impact user trust and conversion rates.
Let's Encrypt is a free, automated, and open Certificate Authority that provides SSL certificates at no cost. It's backed by major organizations including Mozilla, Cisco, and the Electronic Frontier Foundation.
1. Install Certbot
Certbot is the recommended tool for obtaining and installing Let's Encrypt certificates. Installation varies by operating system and web server.
2. Choose Your Web Server
Certbot supports Apache, Nginx, and other popular web servers with automatic configuration.
3. Run Certbot
Execute the appropriate Certbot command for your setup. It will automatically verify your domain and install the certificate.
4. Set Up Auto-Renewal
Let's Encrypt certificates are valid for 90 days. Certbot includes automatic renewal, typically configured via cron or systemd.
