4.3.2.2 Crypto_Mac_AesCmac_Cipher
crypto_Mac_Status_E Crypto_Mac_AesCmac_Cipher(
st_Crypto_Mac_Aes_ctx *ptr_aesCmacCtx_st,
uint8_t *ptr_inputData,
uint32_t dataLen
);Description
This API executes the AES-CMAC operation to compute the Message Authentication Code (MAC). To use this API, first, initialize the context by calling the Crypto_Mac_AesCmac_Init function. Then, invoke this API. Finally, obtain the MAC by calling the Crypto_Mac_AesCmac_Final function.
