A site certificate, also known as an SSL certificate, is a digital document that verifies the identity of a website and encrypts the data that is transmitted between the website and the user’s browser. Checking a site certificate is important because it helps to ensure that the website is legitimate and that the data that is transmitted between the website and the user’s browser is secure.
There are a few different ways to check a site certificate. One way is to look for the padlock icon in the address bar of the browser. If the padlock icon is present, it means that the website has a valid SSL certificate. Another way to check a site certificate is to click on the padlock icon and then click on the “Certificate” tab. This will display the details of the SSL certificate, including the issuer, the validity period, and the subject.
