Exam 312-50v11 topic 1 question 133 discussion

When a user encrypts plaintext with PGP, PGP first compresses the plaintext. The session key works with a very secure, fast conventional encryption algorithm to encrypt the plaintext; the result is ciphertext. Once the data is encrypted, the session key is then encrypted to the recipient's public key

Pretty Good Privacy (PGP) Often used for data compression, digital signing, encryption and decryption of messages, emails, files, directories, and to enhance the privacy of email communications. PGP then creates a random key that is a one-time-only secret key. Once the data are encrypted, a random key is encrypted with the recipient’s public key.The recipient’s copy of PGP uses his or her private key instead of the public key to recover the temporary random key. (P.3091/3075)

What should John do to communicate correctly using this type of encryption? None of these answers are correct. (Though the test will say B is....but....) In PGP, the message is encrypted with a key that is randomnly generated by the Sender. "That key" is then encrypted with the reciever's public key and sent along with the encrypted message to the receiver. At no time is the sender's message encrypted by the receiver's public key.
