What does Pretty Good Privacy (PGP) primarily protect?

Pretty Good Privacy (PGP) primarily focuses on the protection of files on hard drives and emails by providing encryption and decryption services. It is widely used for securing email communication, ensuring that the contents remain confidential and can only be accessed by the intended recipient. PGP employs both symmetric and asymmetric encryption methods, which enhances the security of the messages during transmission and when stored on devices.

The tool is specifically designed to safeguard data integrity, authenticity, and privacy in personal and professional communications. Users can encrypt messages so that only designated recipients with the correct keys can decrypt and read them, effectively limiting unauthorized access to sensitive information.

This functionality is particularly important in an environment where data breaches are common, and the confidentiality of communications is vital. Thus, PGP serves a critical role in protecting sensitive information transmitted through emails and stored files, making it an essential tool for individuals and organizations that prioritize data security.
