How to detect SSL errors using chrome extension?

[Prerit Datta]

Dear all,

Sorry for cross posting it here (posted on stackoverflow with no luck). 

I'm trying to make a chrome extension that plays a specific sound whenever a page with invalid SSL certificate is loaded.

I know that chrome gives certain warnings likes: net::ERR_CERT_AUTHORITY_INVALID err_cert_date_invalid err_cert_common_name_invalid NET::ERR_CERT_REVOKED and so on...

Is there a way to detect it via coding using chrome extensions?

This solution linked here doesn't work for me

I tested it using a self-signed certificate on a dummy html page using Apache tomcat. My background page:

chrome.webRequest.onErrorOccurred.addListener(function(details) { if (details.error == "net::ERR_CERT_AUTHORITY_INVALID") { console.log("Error details:",details); } }, { urls: ['*://*/*'], types: ['xmlhttprequest'] });

An example of page with invalid certificate is: https://www.iad.gov/nietp/CAERequirements.cfm

Thank you all in advance

What does details.error contain in your case?
