What is an SSL Certificate and Why is it Important?
An SSL (Secure Sockets Layer) certificate is a security protocol that encrypts data communication between websites and users. On a website with an SSL certificate, sensitive information entered by users (credit card numbers, passwords, personal information) cannot be read by third parties.
Why Should You Check Your SSL Certificate?
- Check your certificate's validity period
- Verify your security configuration
- Detect weak encryption algorithms
- Check TLS/SSL protocol versions
- Test certificate chain validity
SSL Labs Grading System
SSL Checker uses an SSL Labs style grading system. A+ is the highest grade, while F is the lowest. The grade is calculated based on factors such as protocol support, key exchange strength, cipher suites, and security headers.
