void DRV_CRYPTO_AES_IsrHelper (void)

The ISR processor for AES operations.

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.

AES_ERROR DRV_CRYPTO_AES_AddHeader (void *contextData, void *headerData, uint32_t headerLength)

Add header data (such as Additional Authentication Data) to an AES operation.

AES_ERROR DRV_CRYPTO_AES_AddTweakData (void *contextData, const void *tweakData, uint32_t tweakLength)

Initialize the tweak value for AES XTS support.

AES_ERROR DRV_CRYPTO_AES_AddInputData (void *contextData, void *data, uint32_t dataLength)

Add data to an AES operation.

AES_ERROR DRV_CRYPTO_AES_AddOutputData (void *contextData, void *data, uint32_t dataLength)

Add a data output buffer to an AES operation.

AES_ERROR DRV_CRYPTO_AES_DiscardData (void *contextData, uint32_t discardLength)

Tell the AES operation to discard a number of bytes from the output stream.

AES_ERROR DRV_CRYPTO_AES_AddLenALenC (void *contextData)

Calculate the LenALenC input for an AES-GCM operation and add to the descriptor chain.

AES_ERROR DRV_CRYPTO_AES_Execute (void *contextData)

Execute an AES operation to generate the final result (such as a CMAC or a cipher).

AES_ERROR DRV_CRYPTO_AES_IsActive (void *contextData, AES_ERROR *active)

Returns whether an AES operation is active.

uint32_t DRV_CRYPTO_AES_GetContextSize (void *contextData)

Returns the size of an AES context block based on the AES mode in use.
