SSL Lookup

Created on 3 November, 2022 | Tools | 83 views | 3 minutes read

Secure Sockets Layer (SSL) is a protocol that provides security for communications between web browsers and servers.

SSL lookups are used to verify the identity of a website and to ensure that data passed between the two is encrypted. When you visit a website, your web browser will check to see if the site's SSL certificate is valid. If it is, then your browser will establish an encrypted connection with the server. This ensures that any data passed between the two is private and cannot be intercepted by third parties. If you're ever wondering whether a website is secure, you can look up its SSL certificate. Here's how to do an SSL lookup in three simple steps.

1. Go to the website for which you want to verify the SSL certificate.

2. In your web browser's address bar, look for a padlock icon. This indicates that the connection between your browser and the website is secure.

3. Click on the padlock icon. This will open up a window that displays information about the website's SSL certificate, including who issued it and when it expires.

How to do an SSL Lookup

When you want to find out whether a website is using SSL, you can do an SSL lookup. This will tell you whether the site is secured with an SSL certificate and whether it is using TLS encryption.

To do an SSL lookup, you will need to use the SSL Lookup tool. This tool will give you detailed information about the website's SSL configuration.

Once you have run the lookup, you will be able to see whether the site is using SSL and what type of encryption it is using. If the site is not using SSL, you will see a message saying that it is not secure. If the site is using SSL, you will see information about the certificate, including when it was issued and when it expires.

If you are concerned about the security of a website, you should always check to see if it is using SSL before entering any sensitive information.

What is an SSL Certificate?

An SSL certificate is a digital certificate that is used to establish a secure connection between a web server and a web browser. The certificate contains information about the identity of the website and the website's public key.

When a web browser connects to a website that is using SSL, the browser checks the website's certificate to make sure that it is valid and that the website is who it claims to be. If everything checks out, the browser then uses the public key in the certificate to encrypt any data that is sent to the server.

How to interpret the results of an SSL Lookup

When you perform an SSL Lookup, you are given a variety of information about the certificate. This can include the date it was issued, the date it expires, who issued it, and more. The most important thing to look for is the "Common Name." This is the domain name for that the certificate was issued. If this does not match the domain you are visiting, then there is a good chance that the site is not legitimate and you should not enter any sensitive information.

How to use an SSL Lookup tool

An SSL Lookup tool allows you to check the status of a given SSL certificate. This can be useful when troubleshooting SSL issues, or simply verifying that a given certificate is valid and properly configured.

To use an SSL Lookup tool, simply enter the domain name of the site in question into the search bar. The tool will then perform a lookup of the SSL certificate associated with that domain, and return the results.

The results returned by an SSL Lookup tool will include information on the validity of the certificate, as well as its configuration. This information can be useful in troubleshooting SSL issues. Additionally, if the results show that the certificate is invalid or improperly configured, it may be necessary to contact the site owner or administrator to correct the issue.


Using an SSL Lookup can be a great way to check the security of a website. By entering the URL of a site, you can see whether it has an SSL certificate and what kind of certificate it is. This information can be useful in determining whether a site is safe to visit or not.
