Functions

	Generate Diffie-Hellman Shared Secret Key X and Y Coordinates. More...

int8_t	ECCROMCC26XX_genKeys (uint8_t privateKey, uint8_t publicKeyX, uint8_t publicKeyY, ECCROMCC26XX_Params params)
	Generate Public Key X and Y Coordinates. More...

void	ECCROMCC26XX_init (void)
	Initializes module's synchronization resources. Only needs to be called once, but safe to call multiple times. More...

void	ECCROMCC26XX_Params_init (ECCROMCC26XX_Params *params)
	Function to initialize the ECCROMCC26XX_Params struct to its defaults. params should not be modified until after this function is called. Default parameters use the NIST P-256 curve, timeout is set to wait indefinitely, malloc and free are NULL and status is set to ECCROMCC26XX_STATUS_SUCCESS. A client may call this function with the same params instance any number of times. More...

int8_t	ECCROMCC26XX_signHash (uint8_t privateKey, const uint8_t hash, uint32_t hashLen, uint8_t sign1, uint8_t sign2, ECCROMCC26XX_Params *params)
	Compute the signature of a previously hashed message. More...
