What is the primary purpose of GNU Privacy Guard (GnuPG) in the described scenario?

• A. Encrypting messages
• B. Signing messages
• C. Compressing data
• D. Authenticating users

Answer: (A)

Public-key encryption is what GnuPG is primarily used for in this scenario. Encrypting with the recipient’s public key ensures that only the recipient can decrypt the message with their private key, keeping the content secret from others who might intercept it. GnuPG can also sign messages to prove who sent them and to verify integrity, and it can compress data to save space, but those features address authentication and efficiency, not the confidentiality goal highlighted here.
