		size_t	buf_max,
		const uint8_t *	data,
		size_t	data_len,
		uint16_t	sw )

Builds APDU response payload with status word trailer.

Parameters

buf	Output response buffer.
buf_max	Capacity of buf.
data	Optional payload bytes.
data_len	Payload length.
sw	ISO7816 status word.

apdu_parse()

bool apdu_parse	(	const uint8_t *	raw,
		size_t	raw_len,
		apdu_t *	apdu )

ISO 7816 APDU parsing/building helpers for CDC Badge OpenPGP stack.

Based on pico-openpgp (https://github.com/polhenarejos/pico-openpgp).

Parses raw APDU bytes into structured representation.

Parameters

raw	Raw APDU buffer.
raw_len	Length of raw.
apdu	Output APDU structure.

Returns

true if APDU framing is valid and parsing succeeded.
