lt_ecc_key_read()

lt_ret_t lt_ecc_key_read	(	lt_handle_t *	h,
		const lt_ecc_slot_t	ecc_slot,
		uint8_t *	key,
		const uint8_t	key_max_size,
		lt_ecc_curve_type_t *	curve,
		lt_ecc_key_origin_t *	origin
	)

Parameters

h	Handle for communication with TROPIC01
ecc_slot	Slot number TR01_ECC_SLOT_0 - TR01_ECC_SLOT_31
key	Buffer for retrieving a key; length depends on the type of key in the slot (32B for Ed25519, 64B for P256), according to curve
key_max_size	Size of the key buffer
curve	When the function executes successfully, the type of elliptic curve public key will be written
origin	When the function executes successfully, the origin of the public key (generated/stored) will be written

Return values

LT_OK	Function executed successfully
other	Function did not execute successully, you might use lt_ret_verbose() to get verbose encoding of returned value
