How can I authenticate with a client certificate in a TLS session?

[haga-rak]

I have a .NET x509 cert (System.Security.Cryptography.X509Certificates.X509Certificate2) with its private key which I'd like to use to make a client authentication in a regular tls session (The BC part is the client side).

For this, I'm inheriting TlsCredentials that I expect to return when TlsAuthentication.GetCredentials is called.

In short, this part looks like,

internal class CredentialsWithDotnetCert : TlsCredentials
{
    public CredentialsWithDotnetCert(X509Certificate2 certificate, BcTlsCrypto crypto)
    {
        // .... how to get Certificate from System.Security.Cryptography.X509Certificates.X509Certificate2 ?
        Certificate = new Certificate(new TlsCertificate[] { ..... });
    }


    public Certificate Certificate { get; }
}

But, I'm struggling to create a Org.BouncyCastle.Tls.Certificate from the System.Security.Cryptography.X509Certificates.X509Certificate2 object. Any idea?

I'm not bound to this particular implementation and I'm open to any other way to make this client auth work.

Thank you,
