How to disable “Security Alert” window in Webbrowser control

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:

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.
