What does Pretty Good Privacy (PGP) primarily provide for network communication?

Pretty Good Privacy (PGP) is primarily designed for securing the privacy and authenticity of data in network communications. It uses cryptographic techniques to ensure that messages can only be read by intended recipients and that the identity of the sender can be verified. Through encryption, PGP protects the content of the message from unauthorized access, while digital signatures provide a way for the receiver to confirm that the message has not been altered in transit and that it genuinely comes from the claimed sender. This combination of privacy and authentication features makes PGP a widely used standard for securing email and other forms of communication.

The other options do not accurately reflect PGP's main capabilities. Increased bandwidth pertains to data transmission speed and is unrelated to encryption or authentication. Data recovery features are focused on retrieving lost or corrupted data, which is not the primary function of PGP. Cloud storage integration involves storing data online and does not directly relate to the core functionalities offered by PGP regarding secure communication.
