6.1
MAC
Computes a SHA-256 digest of a key stored inside the chip, an input challenge and other information on the chip. The output
of this command is the digest of this message.
If the message includes the serial number of the chip, then the response is said to be diversified. Protocols that utilize
diversified responses may be more secure because two AT88SA102S chips with same key will return different responses to
an identical challenge based on their unique serial number.
