Yubikey with eM Client


I want to ask if there is some support for Smart cards, namely Yubnikey, in my case as “source of” private key in case of PGP encryption and signing. I so far successfully used my smart card for everything I could have to think of from document encryption to signing of commits over at GitHub. So my question is: Is there any support for smart card and if that is the case, how to set it up?

As far as I know these keys are not usable in eM Client.
