Identità multiple¶
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.
Uso¶
Per cambiare l’identità è sufficiente inviare un comando CCID personalizzato. Questo può essere ottenuto con lo strumento pynitrokey:
Collega il tuo Nitrokey Start e verifica che sia stato riconosciuto.
$ nitropy start list *** Nitrokey tool for Nitrokey FIDO2 & Nitrokey Start :: 'Nitrokey Start' keys: FSIJ-1.2.15-87042524: Nitrokey Nitrokey Start (RTM.10)
Cambia l’identità, sostituendo
<ID>con0,1, o2.$ 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
Limitazioni¶
A partire dalla versione RTM.10 c’è solo una limitazione - la terza identità può memorizzare un certificato non più lungo di 1024 byte. Le altre due identità hanno un limite standard di 2048 byte per certificato.
