.NET Core HttpClient - certificate does not go through to a server










0















I'm trying how to restrict access to an API using certificate. My problem is, that I can not make the certificate to actually make it to the API.



This is how I setup the HttpClient



var handler = new HttpClientHandler();
handler.ClientCertificates.Add(new X509Certificate2("certificate.cer"));

var httpClient = new HttpClient(handler);
httpClient.BaseAddress = new Uri("http://localhost:54261/api/");
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));


Now, on the server side, in custom AuthorizationHandler, I inject IHttpContextAccessor and then try to get the certificate like this



var clientCertificate = _httpContextAccessor.HttpContext.Connection.ClientCertificate;


Unfortunately, clientCertificate is always null.



I generated the self-signed certificates using this software:
http://www.itiverba.com/en/software/itisscg.php



I simply generated a certificate, that is a CA. Then I generated normal certificate that was signed by previously generated CA certificate. I chose to copy both of them into the Certificate Store.



I tried some steps like



  • adding certitifacate to trusted (hopefully did this one correctly)

  • adding SslNegotiateCert in applicationhost.config into sslFalgs

At the end of this, certificate is stil null. Could I ask for some guidance, what might be wrong?
