SSL Certificate Checker

Enter your website URL into the input field and click 'Check SSL Certificate'. The tool will display details about your SSL certificate, including its status and validity.

The tool provides information such as the certificate's expiration date, issuer, validity period, and any issues that might be present.

Regular checks ensure your SSL certificate is valid and up-to-date, preventing security warnings and potential trust issues with your website visitors.

If your SSL certificate is invalid or expired, you should renew or replace it promptly to maintain secure connections and avoid security warnings for your visitors.

Yes, the SSL Certificate Checker can verify various SSL certificates, including Domain Validated (DV), Organization Validated (OV), and Extended Validation (EV) certificates.

It's advisable to check your SSL certificate regularly, especially as the expiration date approaches, to ensure continuous security for your website.

Verify SSL certificates monthly, before expiration dates (most last 90 days with Let's Encrypt, 1 year with commercial CAs), after certificate renewal, when implementing new sites, during security audits, or if users report security warnings. Set reminders for 30 days before expiration.

DV (Domain Validated) verifies domain ownership only, issues quickly, costs less. OV (Organization Validated) verifies business identity, shows organization name, more trusted. EV (Extended Validation) provides highest validation, shows company name in browser, maximum trust. Choose based on business needs.

Browsers show warnings for expired certificates, domain mismatches (certificate for different domain), untrusted certificate authorities, weak encryption, incomplete certificate chains, mixed content (HTTP resources on HTTPS pages), or revoked certificates. Our checker identifies these issues before they affect visitors.

Wildcard certificates (*.example.com) secure a domain and all its subdomains with one certificate. They're cost-effective for sites with multiple subdomains (blog.example.com, shop.example.com, app.example.com). Our checker verifies wildcard coverage and identifies which domains the certificate protects.

HTTPS (SSL/TLS) is a confirmed Google ranking factor. Sites with SSL rank higher than non-secure sites, browsers label HTTP sites as 'Not Secure' deterring visitors, HTTPS is required for modern web features, and user trust increases with padlock icons. SSL is essential for SEO.

Certificate chain links your certificate to a trusted root CA through intermediate certificates. Proper chain installation ensures browsers trust your certificate. Incomplete chains cause trust errors. Our checker verifies the complete chain from your certificate through intermediates to the root CA.

SSL renewal involves generating a new certificate request (CSR), submitting to your CA, installing the new certificate before the old one expires, and configuring servers. Let's Encrypt auto-renews every 90 days. Commercial certificates typically last 1 year and require manual renewal.

Support TLS 1.2 and TLS 1.3 (most secure, fastest). Disable outdated SSL 2.0, SSL 3.0, TLS 1.0, and TLS 1.1 (vulnerable to attacks). Our checker identifies supported protocols. Modern certificates and servers should use only TLS 1.2+ for security compliance.
