Namespace
Yubico.YubiKey.Otp.Commands
Assembly
Yubico.YubiKey.dll

Reads the NDEF data over an NFC connection to the YubiKey.

public class ReadNdefDataCommand : IYubiKeyCommand<ReadNdefDataResponse>
Inheritance
object
ReadNdefDataCommand
Implements

Remarks

The NDEF data file must be selected first using the SelectNdefDataCommand class.

This command will only succeed if the YubiKey is connected through an NFC reader. It will not work over CCID if plugged in by USB or EAP.

Methods

CreateCommandApdu()

Creates a well-formed CommandApdu to send to the YubiKey.

public CommandApdu CreateCommandApdu()

Returns

CommandApdu

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

Remarks

This method will first perform validation on all of the parameters and data provided to it. 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 ReadNdefDataResponse CreateResponseForApdu(ResponseApdu responseApdu)

Parameters
