Question

I’m using Webbrowser control to login to HTTPS site with ‘untrusted certificate’. but I get popup such standart window ‘Security Alert’ about untrusted certificate:

I have to find this window by title and send it Alt+Y to press Yes:

int iHandle = NativeWin32.FindWindow(null, 'Security Alert'); NativeWin32.SetForegroundWindow(iHandle); System.Windows.Forms.SendKeys.Send('Y%'); 

but user can see a flickering of this window.

How can I ignore this alert?
Or disable this ‘untrusted certificate’ check in Webbrowser control?

Answer 1

This should do it:

public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) {     return true; }  ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateServerCertificate); 

Obviously, blindingly allowing certificates is a security risk. Be careful.
