How to Check the SSL Information of Websites

An SSL certificate provides an extra layer of security between a website and a browser. It both serves to authenticate the website’s identity and to encrypt any information provided through the website. If you want to view an SSL certificate's information, such as the SSL issuer/provider, there is no need for an SSL checker tool, as you can simply view a website's SSL certificate via your browser's address bar. This article discusses how to view a website's SSL certificate depending on what browser you're using.
