Answer / guest
Answer: A
The message digest is calculated and included in a digital
signature to prove that the message has not been altered. It
should be the same value as a recalculation performed upon
receipt. It does not define the algorithm or enable the
transmission in digital format and has no effect on the
identity of the user, being there to ensure integrity rather
than identity.
