FIDO/U2F support

Question

Dear Rebex team,

is it possible to use Rebex ssh with a physical FIDO/FIDO2/U2F/CTAP1/CTAP2-compatible Security Key?

Like described in

https://ubuntu.com/server/docs/how-to/security/two-factor-authentication-with-u2f-or-fido

https://developers.yubico.com/SSH/Securing_SSH_with_FIDO2.html

Thanks.

Unfortunately, Rebex SSH does not support FIDO/U2F. We only support physical security keys via Microsoft's CNG API (KSP) or using a custom implementation of system's AsymmetricAlgorithm class, which can be used to initialize the SshPrivateKey class.
