Answer:
A digital signature involves encrypting a cryptographic hash, or digest, generated from the
message and we will not encrypt the message itself because in general digital signature systems
has a feature to be very slow if the message is lengthy so it is better to sign a message which has
under gone hash function operation(i.e reduced message) rather than the message itself.
