Since Chrome 58, self-signed certificates generated with Bearsampp are no longer accepted and you will have the error NET::ERR_CERT_AUTHORITY_INVALID if you go to https://localhost.  To resolve this you can add the .crt files to the local trusted certificate store using the steps below.

• First go to the ssl folder of bearsampp and locate the .crt file then right click on the .crt file and select "Install certificate"
  
•  Next choose "local machine"
  
• Next choose "Place all certificates in the following store" and then select "Trusted Root Certificate Authorities"
  
• Now choose "finish"
  
• Repeats for each .crt
• Close and reopen the browser
