Frequently Asked Questions
Everything you need to know about SSL certificates and security
About SSL Certificates
What is an SSL certificate?
An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection between a web server and a browser. It ensures that data transmitted remains private and integral.
How do I know if my website has a valid SSL certificate?
You can check if your website has a valid SSL certificate by looking for "https://" in the URL and a padlock icon in the browser address bar. Our SSL Certificate Checker provides detailed information about your certificate's validity and configuration.
Certificate Management
How often should I check my SSL certificate?
It's recommended to check your SSL certificate monthly, or set up automated monitoring. Certificates typically expire after 1-2 years, and you should renew them at least 30 days before expiration to avoid service interruptions.
What happens if my SSL certificate expires?
If your SSL certificate expires, browsers will display security warnings to visitors, potentially blocking access to your site. This can significantly impact user trust, SEO rankings, and business operations.
Technical Details
What is a certificate chain?
A certificate chain is a sequence of certificates where each certificate is signed by the next certificate in the chain. It starts with your website's certificate and ends with a root certificate from a trusted Certificate Authority (CA). This chain establishes trust and authenticity.
What are Subject Alternative Names (SAN)?
Subject Alternative Names (SAN) is an extension to SSL certificates that allows multiple domain names to be protected by a single certificate. This is useful for securing multiple subdomains or different domain variations with one certificate.
Privacy & Security
Our SSL Certificate Checker only retrieves publicly available certificate information. No sensitive data is accessed or stored, ensuring your website's privacy and security remain intact.
