How to use the SSL Certificate Checker

1

Enter a website URL

Type the domain you want to check, such as "laiuse.com". Include no https:// prefix — the tool adds it automatically.

2

Run the check

Click Check. The tool connects to the domain and retrieves its SSL certificate details.

3

Review certificate info

See the certificate issuer, validity dates, encryption strength, and chain of trust. A valid certificate shows as green; issues are flagged in red.

4

Act on the results

If the certificate is expired or invalid, the domain owner needs to renew or replace it. An A+ rating means the site uses modern TLS configuration.

Pro tips

  • SSL issues cause browsers to show "Not Secure" warnings — check your site regularly.

  • Use this after renewing an SSL certificate to confirm the new certificate is active.
