       Support for a NULL digest through the EVP_MD API.  This algorithm does nothing and returns 1 for its
       init, update and final methods.

   AlgorithmName
       The following algorithm is available in the default provider:

       "NULL"

   GettableParameters
       This implementation supports the common gettable parameters described in EVP_MD-common(7).
