## This experiment demonstrates that the claimed "hash" (that is not a hash) used

## and can be trivially reverse engineered by anyone who owns one of the machines
## with the hardware (such as any M1 Mac), in seconds to days. Therefore, this proves
## that no "insider" access or leak is necessary to obtain this table, and that the
## attackers most likely did exactly the same thing.

## This is the "black box", i.e. the hardware: The table is not exposed to the caller.
