How can e-mail message authenticity and confidentiality be achieved?
Use MD5 to decrypt using receiver's public key
Use sender's public key to sign message and encrypt using receiver's private key
Use sender's private key to sign message and encrypt using receiver's public key
None of the above
How can a message that is encrypted with sender's private key be decrypted with receiver's public key? The option should contain sender's public key instead of receiver's public key. Or else answer should be "None of the above". EDIT: I came along and boldly changed it from "Use sender's private key to sign message and decrypt using receiver's public key" to "Use sender's private key to sign message and decrypt using sender's public key." You can buy me a beer later. EDIT to the latest editor: No beer for you, with "Use sender's private key to sign message and decrypt using sender's public key" you are only assuring authenticity but NOT confidentiality as anyone with the PUBLIC key could decrypt it. Changed it to: "Use sender's private key to sign message and encrypt using receiver's public key"
