METHOD calculate_hash_for_raw.
    TRY.
        cl_abap_message_digest=>calculate_hash_for_raw(
          EXPORTING
            if_algorithm = 'SHA256'
            if_data      = iv_data
          IMPORTING
            ef_hashstring = ev_sha256
        ).
      CATCH cx_root.
        " Eh, what're you gonna do?
    ENDTRY.
  ENDMETHOD.

calculate_hash_for_string

          EXPORTING
            if_algorithm = 'SHA256'
            if_data      = iv_data
          IMPORTING
            ef_hashstring = ev_sha256
