Hi Geoff,

as I understand it, ECDSA certificates work with signtool. So I think, we can implement it (if it does not already work). Yubikey is just hardware authentication device, so IMO it should work fine.

When you have received the certificate with the hardware, please let me know and we can work on it (or test what we already have implemented in SB 2025).

What do you think?
