Cy_Crypto_Core_Cmac()

__STATIC_INLINE cy_en_crypto_status_t Cy_Crypto_Core_Cmac	(	CRYPTO_Type *	base,
		uint8_t const *	message,
		uint32_t	messageSize,
		uint8_t const *	key,
		cy_en_crypto_aes_key_length_t	keyLength,
		uint8_t *	cmac,
		cy_stc_crypto_aes_state_t *	aesState
	)

Calculates the AES Cipher-based Message Authentication Code (CMAC) on the input message with the provided key.

Parameters

base	The pointer to the CRYPTO instance.
message	The pointer to the source plain text. Must be 4-byte aligned.
messageSize	The size of the source plain text in bytes.
key	The pointer to the encryption key. Must be 4-byte aligned.
keyLength	cy_en_crypto_aes_key_length_t
cmac	The pointer to the calculated CMAC.
aesState	The pointer to the AES state structure allocated by the user. The user must not modify anything in this structure.

Returns

cy_en_crypto_status_t

Cy_Crypto_Core_Hmac()

__STATIC_INLINE cy_en_crypto_status_t Cy_Crypto_Core_Hmac	(	CRYPTO_Type *	base,
		uint8_t *	hmac,
		uint8_t const *	message,
		uint32_t	messageSize,
		uint8_t const *	key,
		uint32_t	keyLength,
		cy_en_crypto_sha_mode_t	mode
	)

Performs the HMAC calculation.

Parameters

base	The pointer to the CRYPTO instance.
hmac	The pointer to the calculated HMAC. Must be 4-byte aligned.
message	The pointer to the message whose hash value is being computed.
messageSize	The size of the message.
key	The pointer to the key.
keyLength	The length of the key.
mode	cy_en_crypto_sha_mode_t

Returns

cy_en_crypto_status_t
