I’m not sure if this applies to Beta but at least for Chrome 57 it does. You can usually check the certificate information on Chrome when clickin on the “Secure” word before “https” even if it is not secure (self-signed certificate, sources form unsecure sources) you are able to see the certificate by clicking it and then in the menu click in the “view details” button.
Well, in Chrome 57 it is not there.
So, if the “view details” button is no longer there, where can I see the certificate information?. well, you have to open the developer console, there is the “security” tab and there is the information related to the certificate.
