Documentation: PGP and S/MIME simultanous use

[szszszsz]

Feature request to use both PGP and S/MIME together, simultaneously.
Ticket for idea tracking. Since this is not a task for firmware implementation, tagging as invalid.

Details: https://support.nitrokey.com/t/pgp-smime-simultaneously-with-nk-pro-2/2100/3

Cross-linking:

• openpgp: fixing key usage flags for slot 3 (S/MIME Usage) OpenSC/OpenSC#1843
• OpenPGP v3.3: Support multiple certificates OpenSC/OpenSC#1399
• Experimental: PKCS#11 Support for Multiple Applications on One Card OpenSC/OpenSC#1263
• Concurrent access to multiple applications on card - Yubico, MyEID and others  OpenSC/OpenSC#962

This is already working with OpenSC and GnuPG. The only downside is that you can not (at least easily) use slot 3 (authenticate) for GnuPG stuff. But OpenSC can nearly always used as replacement.

Scenario:
Slot 1 = GnuPG key with SC usage flag
Slot 2 = GnuPG key with E usage flag
Slot 3 = S/MIME key + Cardholder certificate

The linked issues are partly misunderstood imho because they are about extending OpenSC based on new hardware possibilities but does not help for the PGP/S/MIME use case. (e.g. letting import multiple certs would allow two S/MIME keys in one card)

actually, I think this ticket can be closed

Is there any documentation describing how to initialize a Nitrokey to use it for both GPG and S/MIME? I believe this should be created before closing this ticket.
