Question

type in bobs name, then pgp would find bobs public key and automatically perform all the encryption. at the same time pgp would do the necessary jiggery - pokery required to digitally sign the message. upon receiving the encrypted message, bob would select the pgp option, and pgp would decrypt the message and verify the author. nothing in pgp was original—diffie and hellman had already thought of digital signatures and other cryptographers had used a combination of symmetric and asymmetric ciphers to speed up encryption—but zimmermann was the first to put everything together in one easy - to - use encryption product, which was efficient enough to run on a moderately sized personal computer. which fact most effectively supports the claim that pgp can be used by an ordinary person? pgp is based on complicated mathematics. pgp works efficiently on a personal computer.

Explanation:

The fact that PGP works efficiently on a personal - computer implies that it can be used by an ordinary person as personal computers are commonly owned by regular users. The mention of complicated mathematics does not support ease - of - use for an ordinary person.

Answer:

PGP works efficiently on a personal computer.
