SSL Lookup

An SSL lookup means verifying the SSL/TLS configurations of a website or an application. This will assist in determining whether a certain website is on HTTPS, whether it has a current SSL certificate, or does it meet certain set standards on security.

How to Perform an SSL Lookup

Use Browser Features:

Ensure the padlock symbol in your browser at the bottom part of the webpage is a green colour. Expanding the certificate we can find information about encryption, for example, and the period it is valid for.

Online SSL Lookup Tools:

To test a website’s SSL comprehensively, all and sundry can use web-based platforms such as https://toolchecking.com/ssl-lookup/ and DigiCert.

Troubleshooting:

An SSL lookup can reveal problems in the switch and concentrations of the domains or validity of the certificates used.

Lookup SSL Certificate

To lookup an SSL certificate will mean to search for certain detail regarding the SSL/TLS current certificate being in use. This may be useful for webmasters, IT admins who want to secure their connections as well as the average user.

Key Information You Can Find

• Issuer: The CA that issued the certificate.
• Validity Period: The beginning and end of issuance of the certificate.
• Encryption Details: The type of encryption used (for instance 2048-bit RSA).
• Subject: The name of the domain or the name of the entity to which the certificate was SAN issued.

Example

If a website has an unfamiliar or considered untrusted CA, a user can have doubts about the site’s legitimacy and would not enter their personal information.

Search SSL Certificate Serial Number

It provides an opportunity to find and check the unique serial number assigned to an SSL certificate by the issuing Certificate Authority. This serial number is very important for certificate administration, particularly in case of massive certificate environments.

What Is Serial Number Lookup?

• Troubleshooting Revoked Certificates: The serial number can be used to verify if the certificate was revoked by the CA through CRL or OCSP.
• Auditing and Compliance: Part of the certificate management process IT teams utilize serial numbers to track and audit certificates needed for compliance.

How to Lookup an SSL Certificate’s Serial Number

Browser:

Click on viewing the certificate information through the padlock and expand the serial number section.

Command Line:

openssl s_client -connect example.com:443 | $openssl x509 -noout -serial

Conclusion

Any online connection requires SSL certificates, though they may be only important to experienced users. When you use SSL certificate lookup, SSL cert lookup and SSL certificate serial number lookup you will be able to check whether a certificate is genuine or not, whether the certificate has been installed rightly and whether the users will be able to trust the site.
