Ask the security key to register with a particular origin & client. Args: challenge_param: Arbitrary 32 byte challenge string. app_param: Arbitrary 32 byte applciation parameter. Returns: A binary structure containing the key handle, attestation, and a signature over that by the attestation key. The precise format is dictated by the FIDO U2F specs. Raises: TUPRequiredError: A Test of User Precense is required to proceed.

Ask the security key to sign a challenge for a particular key handle in order to authenticate the user. Args: challenge_param: SHA-256 hash of client_data object as a bytes object. app_param: SHA-256 hash of the app id as a bytes object. key_handle: The key handle to use to issue the signature as a bytes object. check_only: If true, only check if key_handle is valid. Returns: A binary structure containing the key handle, attestation, and a signature over that by the attestation key. The precise format is dictated by the FIDO U2F specs. Raises: TUPRequiredError: If check_only is False, a Test of User Precense is required to proceed. If check_only is True, this means the key_handle is valid. InvalidKeyHandleError: The key_handle is not valid for this device. ApduError: Something else went wrong on the device. �CmdAuthenticater � r r ) r r r r r r r r r ZCMD_AUTHr r )r r r � key_handleZ check_onlyZcontrolr r r r r r G s �� �zSecurityKey.CmdAuthenticatec C sB | j �d� | �t�dtjdd��}|�� s<t�|j |j ��|j S )a� Obtain the version of the device and test transport format. Obtains the version of the device and determines whether to use ISO 7816-4 or the U2f variant. This function should be called at least once before CmdAuthenticate or CmdRegister to make sure the object is using the proper transport for the device. Returns: The version of the U2F protocol in use. � CmdVersionr ) r r r r r Z CMD_VERSIONZ IsSuccessr � ApduError�sw1�sw2r )r r r r r r r s �zSecurityKey.CmdVersionc C s | j �d� | j�|� d S )N�CmdBlink)r r r Z SendBlink)r �timer r r r# � s zSecurityKey.CmdBlinkc C s | j �d� | j�� d S )N�CmdWink)r r r ZSendWink)r r r r r% � s zSecurityKey.CmdWinkc C s | j �d� | j�|�S )N�CmdPing)r r r ZSendPing)r �datar r r r& � s zSecurityKey.CmdPingc C s` d}| j sFt�| j�|�� ��}|jdkr\|jdkr\d| _ | �|�S nt�| j�|� � ��}|S )a, Send an APDU to the device. Sends an APDU to the device, possibly falling back to the legacy encoding format that is not ISO7816-4 compatible.
