Explanation:

: As stated in the official CCSE NG courseware, “A digital signature is a code that can be attached
to an electronically transmitted message that uniquely identifies the sender, and verifies that the
message hasn’t been tampered with in transit. Like a written signature, the purpose of a digital
signature is to guarantee that the individual sending the message is really who claims to be. Digital
signatures use public key cryptography”. Se e Page 7.8 of CCSE NG Official Courseware. (VPN1-FW1 Management II NG FP-1).
