But how can I add .key + password to a WebRequest in C#?

X509Certificate2 certificate = new X509Certificate2("~/Cert/mykey-wru.key", "PASSWORD");

Answer 1

My answer is combinde with creating the suggestes .pfx file and adding the cert to the local machine store.

than i needed to read them from there in order to get a seure ssl connection

foreach (X509Certificate2 certificate in store.Certificates)
            {
                if (certificate.FriendlyName.Contains("mycert"))
                    request.ClientCertificates.Add(certificate);
            }
