Identités multiples

The multiple identities feature allows to use 3 virtual smart cards in place of one, giving bigger flexibility in the every day use, as well as separation between user identities (business, personal etc.) or even allowing usage of it for more than one user (PINs are separate).

All of the smart cards have separate data objects, meaning they all could have different keys, certificates stored, and PINs set. Identities do not interact between each other.

The virtual smart cards are identifiable by the first digit of the serial number, which is replaced by identity number for second (“1”) and third one (“2”). Serial number is not changed for the first identity.

Utilisation

Pour changer l’identité, il suffit d’envoyer une commande CCID personnalisée. Ceci peut être réalisé avec l’outil pynitrokey :

1. Installer pynitrokey.

2. Connectez votre Nitrokey Start et vérifiez qu’il a été reconnu.

   $ nitropy start list
   *** Nitrokey tool for Nitrokey FIDO2 & Nitrokey Start
   :: 'Nitrokey Start' keys:
      FSIJ-1.2.15-87042524: Nitrokey Nitrokey Start (RTM.10)
   

3. Changez l’identité, en remplaçant <ID> par 0, 1, ou 2.

   $ nitropy start set-identity <ID>
   *** Nitrokey tool for Nitrokey FIDO2 & Nitrokey Start
   Trying to set identity to <ID>
   device has reset, and should now have the new identity
   

Limites

Depuis la version RTM.10, il n’y a qu’une seule limitation - la troisième identité peut stocker un certificat d’une longueur maximale de 1024 octets. Les deux autres identités ont une limite standard de 2048 octets par certificat.
