lt_in__ecc_key_read()

lt_ret_t lt_in__ecc_key_read	(	lt_handle_t *	h,
		uint8_t *	key,
		const uint8_t	key_max_size,
		lt_ecc_curve_type_t *	curve,
		lt_ecc_key_origin_t *	origin
	)

Note

Used for separate L3 communication, for more information read info at the top of this file.

Parameters

h	Handle for communication with TROPIC01
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

Returns

LT_OK if success, otherwise returns other error code.
