2.1.5.9 DRV_CRYPTO_AES_Initialize()
AES_ERROR DRV_CRYPTO_AES_Initialize (void * contextData, AESCON_MODE mode, AESCON_OPERATION operation, void * key, uint32_t keyLength, void * initVector, uint32_t initVectorLength)
Initialize a new AES operation.
| contextData |
The context data for this operation. |
| mode |
The AES_MODE mode to use. |
| operation |
The AESCON_OPERATION operation to perform. |
| key |
The AES key to use. |
| keyLength |
The length of the AES key. |
| initVector |
The initalization vector (IV) data to use. |
| initVectorLength |
The length if the IV data. |
AES_NO_ERROR on success, AES_STATE_ERROR/AES_INITIALIZE_ERROR on failure. |
Note:
Reinitializing an AES operation in progress will void the previous operation.
