What does a digital signature verify about a message?
- A.That only the intended recipient can read the message; a digital signature provides confidentiality but not integrity
- B.The identity of the sender and that the message was not altered
- C.That the message was sent using HTTPS
- D.That the message was encrypted
Why B 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.
