tampered state, meaning they have been tampered with. Additional
information can also be queried from the DataSeal. This is the most useful
and commonly used command in the system.
8. Tampered
The Tampered command is used to communicate with tampered
DataSeals. The command operates the same as the Ve ri fy command only

DataSeals environment.

Wire must be connected and closed in order for a DataSeal to be set. The
