SSL Checker

Before you do any online purchases or banking make sure the website you are going to is safe and has up to date SSL certificates.

https://www.sslshopper.com/ssl-checker.html

or

https://www.digicert.com/help/

Type in the public web address, in this example I have used www.amazon.com then click Check SSL.

As you can see this site has been verified as safe : "Congratulations! This certificate is correctly installed".
