Inheritance
object
DeviceResetCommand
Implements

Remarks

Resets ALL YubiKey applications (including FIDO and PIV) on the key to factory settings. This type of reset is only available on YubiKey Bio Multi-protocol Edition keys.

A reset will delete all FIDO2 credentials, fingerprints, and associated information, remove the shared PIN, delete all PIV keys and certificates from PIV slots (except the F9 attestation slot), remove any information added to the PIV data elements, and set the PIV PUK and management key back to their factory default states.

Returns

CommandApdu

A valid CommandApdu that is ready to be sent to the YubiKey, or passed along to additional encoders for further processing.

The CommandAPDU it creates should contain all of the data payload for the command, even if it exceeds 65,535 bytes as specified by the ISO 7816-4 specification. The APDU will be properly chained by the device connection prior to being sent to the YubiKey, and the responses will collapsed into a single result.

public DeviceResetResponse CreateResponseForApdu(ResponseApdu responseApdu)

Parameters

responseApdu ResponseApdu
