Quizplus · Accepted Answer

The message digest is not encrypted with a receiver's public key to create a digital signature. Instead, the message digest is encrypted with the sender's private key to create a digital signature. The receiver then uses the sender's public key to decrypt the signature and verify the integrity of the original message.
