X509Identity problems

[ondrejpazintelegrafia]

Hello.
Is it possible to use X509Identity as IUserIdentity to open ClientSessionChannel?

I want to use .pfx certificate to authentificate user. Is it possible to do?
Constructor X509Identity(X509Certificate certificate, RsaKeyParameters privateKey) has privateKey parameter. I don't have privateKey.

Today this software requires pem-encoded certificate and private key files.

You may be able to use openssl to convert a .pfx file to pem-encoded files.

You can also try code like this to load the .pfx file

// try load pfx.  pfx files can have password
{
    var x509Identity = default(X509Identity);
    var crtPassword = "password";
    var userCertInfo = new FileInfo(Path.Combine(pkiPath, "user", "certs", "ctt_usrT.pfx"));
    if (userCertInfo.Exists)
    {
        using (var crtStream = userCertInfo.OpenRead())
        {
            var store = new Pkcs12StoreBuilder().Build();
            store.Load(crtStream, crtPassword?.ToCharArray() ?? Array.Empty<char>());
            var alias = store.Aliases.First();
            var cert = store.GetCertificate(alias);
            var key = store.GetKey(alias);
            x509Identity = new X509Identity(cert.Certificate, key.Key as RsaKeyParameters);
        }
    }
}
