<s>[INST] Two clients, Alice and Bob, use PGP to encrypt their emails to each other. Suppose the clients share a common friend, Charlie. Now, suppose that Charlie also generates a PGP key pair. He gives his public key to Alice and Bob, and they both encrypt their emails to him.

Suppose an attacker, Eve, is able to intercept emails and also has access to the public keys of Alice, Bob, and Charlie.

In this scenario, can Eve use Charlie's public key to decrypt Alice's emails intended for Bob, or Bob's emails intended for Alice?[/INST]
