KeyCompute Command MAC
The input and output MACs are both calculated using the parent key.
Both MACs are calculated using the following 14 bytes in the default authenticate-only block:
If any of the optional authenticate fields are selected in the mode parameter, then a second authenticate-only block is included
in the MAC calculations.
KeyExport Command – KeyImport MAC
The MAC is calculated using the following 14 bytes in the default authenticate-only block:
If any of the optional authenticate fields are selected in the mode parameter, then a second authenticate-only block is included
in the MAC calculation.
KeyExport Command – KeyLoad MAC
