HAL_HASH_MD5_Accmlt_IT() function

Consecutive calls to HAL_HASH_MD5_Accmlt_IT() can be used to feed several input buffers back-to-back to the Peripheral that will yield a single HASH signature once all buffers have been entered. Wrap-up of input buffers feeding and retrieval of digest is done by a call to HAL_HASH_MD5_Accmlt_End_IT(). Field hhash->Phase of HASH handle is tested to check whether or not the Peripheral has already been initialized. The input buffer size (in bytes) must be a multiple of 4 otherwise, the HASH digest computation is corrupted. Only HAL_HASH_MD5_Accmlt_End_IT() is able to manage the ending buffer with a length in bytes not a multiple of 4.
