SSL Lookup

Perform a real-time SSL certificate lookup for any domain. Verify certificate validity, issuer information, and expiration dates.

Using the SSL Lookup

A valid SSL certificate is the backbone of web security. Use this tool to inspect any site's certificate, ensuring that data transmitted is encrypted and that the issuer (CA) is trusted by modern browsers.

How it Works

1
Enter the website URL (e.g., https://google.com).
2
Press Check to retrieve the public certificate chain.
3
Review the "Valid From" and "Valid To" dates.
4
Verify the "Issuer" (e.g., Let's Encrypt, DigiCert) to ensure authenticity.

Frequently Asked Questions
