Before somewhere around Chrome 55, I could look at the details of a certificate a website is using by clicking on the Green lock icon:

enter image description here

Now that functionality seems to be gone; see picture below:

How can I bring this back? I know I can go into Developer Console -> Security but it's a tad impossible:

I want to know that i'm seeing the correct certificate (e.g. issuing authority, SHA-1 fingerprint); and that someone isn't attempting to intercept my communications.

How to do it in Edge

It is possible to view a site's TLS certificate in Microsoft Edge, although it's somewhat tedious:

  • Click the ... option

    enter image description here

  • Click Open with Internet Explorer

    enter image description here

  • Click the đź”’ in the address bar, and select View Certificates

    enter image description here

  • And now you have the details of TLS certificate

    enter image description here

Tedious; although one step shorter than viewing it in Chrome (when DevTools are available).


As of Chrome 60 it is possible to return certificate details under "lock" menu. This option has to be enabled manually by accessing chrome://flags/#show-cert-link.

When you enable it and restart the Chrome, option to view certificate will be visible when you click on lock icon.


As far as I know the Developer Tools are the only way of showing it without installing a extension from the Chrome Web Store, but if a extension is okay you could use "CertViewer" ("https://chrome.google.com/webstore/detail/certviewer/dcfpfgpnkmklbdnicbooifodgdekdgie").


I don't know if there is a way to view the certificate faster in Chrome however, you could bookmark an SSL Checker website like this one:


Like I said, there could be a better way but this is all I know of and is what I use to check important websites before I use them. I hope this helped :)
