SSL Certificate Checker verifies HTTPS certificates, displays expiration dates, issuer details, and certificate chain. Essential for maintaining secure websites and ensuring certificate validity.
An SSL certificate encrypts data between a browser and server, enabling secure HTTPS connections. Required for secure websites.
Expired certificates break HTTPS access and lose trust in browsers. Set reminders before expiration to renew in time.
Browsers will show security warnings and prevent access. Users won't trust your site. Renew certificates 30 days before expiration.
Most certificates last 1-2 years. Set calendar reminders to check 60 days before expiration.
