As mentioned in: nitrokey.com/documentation/ … an-i-store "…can store three RSA key pairs. All keys use the same identity but are used for different purposes: authentication, encryption and signing.
I use both, GnuPG and S/MIME keys. I want add GnuPG and S/MIME keys to my Nitrokey Pro.
Referring to linked documentation above and assuming I started with GNUPG sub-keys - one for authentication, one for encryption and one for signing - I’m wondering, if there is still space for my S/MIME client keys?
Or, do I have to make a selection? Or forget about GnuPG sub-keys for authentication, for encryption and for signing, but one GnuPG sub-key for everything in order to have enough space for my S/MIME client keys?
What would you do in my shoes?
cheers & thx for your feedbacks
