What does a digital signature verify about a message?
- A.That the message was encrypted
- B.That only the intended recipient can read the message
- C.That the message was sent using HTTPS
- D.The identity of the sender and that the message was not altered
Why D is correct
A digital signature verifies two things: authentication (the message came from the claimed sender) and integrity (the message has not been modified in transit). The sender signs with their private key, and anyone with the sender's public key can verify the signature.
