Switching Nitrokey Start identities

Alternative MI switching method

pynitrokey installation is not always possible, hence describing below alternative method to change the Identity on the Nitrokey Start. It suffices to have any CCID application installed, and send the following APDU 00 85 00 {ID} (hex), where ID is in range [0;2]. After receiving this command Nitrokey Start will reboot with the selected identity.

Here is how to do it using GnuPG:

# Setting ID to 2
$ gpg-connect-agent --hex "scd apdu  00 85 00 02" /bye
ERR 65539 Unknown version in packet <Unspecified source>

# Alternative error messsage
ERR 65572 Bad certificate <Unspecified source>

The error message here is expected due to immediate reboot of the device, and with losing the connection.

When the ID change is attempted to be done immediately, the following response could be received:

ERR 100663406 Card removed <SCD>

To restore the communication, either kill the gpg-agent or run gpg --card-status again.

Tip: alternative gpg-connect-agent reloadagent /bye is not sufficient.

Compatibility

nitropy requires Python 3.10 or later.
