Enumeration Type Documentation

AuthMode

enum class m5::nfc::a::mifare::desfire::AuthMode : uint8_t

strong

Authentication mode.

Enumerator

AES	AES only.

Function Documentation

make_native_wrap_command()

std::vector< uint8_t > m5::nfc::a::mifare::desfire::make_native_wrap_command	(	const uint8_t	ins,
		const uint8_t *	data = nullptr,
		const uint16_t	data_len = 0 )

Make native wrap command.

Something similar to APDU but different

Parameters

ins	Native INS
data	Data
data_len	Data length

Returns

Constructed command data
