如何禁用“安全警报"Webbrowser 控件中的窗口

How to disable quot;Security Alertquot; window in Webbrowser control(如何禁用“安全警报Webbrowser 控件中的窗口)

问题描述

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?

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.
