浏览器不读取客户端证书

Question

I am trying to read a certificate using the following code

if (Page.Request.ClientCertificate.IsPresent)
{
    HttpClientCertificate cs = Request.ClientCertificate;
    string entireSubjectLine = cs.Subject.ToString();

    if (entireSubjectLine != "")
    {
        lblResponse.Text = entireSubjectLine;
    }
    else
    {
        lblResponse.Text = "No Data";
    }
}

This line - if (Page.Request.ClientCertificate.IsPresent) is returning false , means certificate is not being read. How to achieve it?

Answer 1

This is how you configure IIS to accept certificates:

This seems to make your site ask for certificates though, even if you use Accept and not Require .

Not sure if you want that.

This is for IIS. For IIS Express you can see here: https://improveandrepeat.com/2017/07/how-to-configure-iis-express-to-accept-ssl-client-certificates/
