Identidades múltiples

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

Para cambiar la identidad basta con enviar un comando CCID personalizado. Esto se puede conseguir con la herramienta pynitrokey:

  1. Instalar pynitrokey <https://github.com/Nitrokey/pynitrokey#installation>.

  2. Conecta tu Nitrokey Start y comprueba que lo han reconocido.

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

  3. Cambia la identidad, sustituyendo <ID>` por ``0, 1 o 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

Limitaciones

A partir de la versión RTM.10 sólo hay una limitación: la tercera identidad puede almacenar un certificado de no más de 1024 bytes. Las otras dos identidades tienen un límite estándar de 2048 bytes por certificado.
