lt_ecc_ecdsa_sign()

lt_ret_t lt_ecc_ecdsa_sign	(	lt_handle_t *	h,
		const lt_ecc_slot_t	ecc_slot,
		const uint8_t *	msg_hash,
		const uint32_t	msg_hash_len,
		uint8_t *	rs
	)

Parameters

h	Handle for communication with TROPIC01
ecc_slot	Slot containing a private key, TR01_ECC_SLOT_0 - TR01_ECC_SLOT_31
msg_hash	Buffer containing a 32-byte hash of the message to sign
msg_hash_len	Length of the hash; must be exactly 32 bytes
rs	Buffer for storing a signature in a form of R and S bytes (should always have length 64 B).

Return values

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