5. In HMAC mode, there is no Accumulate API. Only Start API is available.
6. In case of using DMA, call the DMA start processing e.g.
HAL_HASH_SHA1_Start_DMA(). After that, call the finish function in order to get the
digest value e.g. HAL_HASH_SHA1_Finish()
7. Call HAL_HASH_DeInit() to deinitialize the HASH peripheral.
