Is possible get current X509Certificate while loading (OnBeforeResourceLoad) request?
My scope is detect when somebody use reverse proxy https decription (like fiddler) with X509 self signed cert, then i need to detect what is current cert.

I tried this it return right at first start then it dont "update" :

protected override CefReturnValue OnBeforeResourceLoad(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, IRequest request, IRequestCallback callback)
        {
               var cert = chromiumWebBrowser.GetVisibleNavigationEntryAsync().Result.SslStatus;
               Console.WriteLine(cert.X509Certificate?.SubjectName);

but dont retunr current cert for unknow reason

OnBeforeResourceLoad is called before a request is made.

CEF doesn't support obtaining the certificate for an individual resource load.

You can call GetVisibleNavigationEntryAsync when the page has finished loading to obtain the certificate.

CEF feature requests can be made at https://magpcss.org/ceforum/viewforum.php?f=7

You can probably hack something together as a workaround, make a request for the main frame using .Net http client, check the certificate then execute the callback to continue/cancel the request.
