Certified Ethical Hacker (CEH) — Question 52

To send a PGP encrypted message, which piece of information from the recipient must the sender have before encrypting the message?

Answer options

• A. Recipient's private key
• B. Recipient's public key
• C. Master encryption key
• D. Sender's public key

Correct answer: B

Explanation

The sender needs the recipient's public key to encrypt the PGP message, ensuring that only the recipient can decrypt it with their private key. The recipient's private key is not shared and cannot be used by the sender, while the master encryption key and sender's public key are irrelevant to the encryption process for the recipient.
