Question 18

Which of the following choices accurately describes how PGP works when encrypting email?

PGP encrypts the message with the recipients public key, then encrypts this key with a random asymmetric key.

PGP creates a random asymmetric key that it uses to encrypt the message, then encrypts this key with the recipient's public key

PGP creates a random symmetric key that it uses to encrypt the message, then encrypts this key with the recipient's public key

PGP encrypts the message with the recipients public key, then encrypts this key with a random symmetric key.

Correct Answer: C

PGP works by creating a random symmetric key to encrypt the message. This symmetric key is then encrypted using the recipient's public key. The combination of symmetric and asymmetric encryption ensures both the security and efficiency of the encryption process. Symmetric encryption is faster for encrypting the actual message, while asymmetric encryption securely transmits the symmetric key.
