Pretty Good Privacy

Pretty Good Privacy (PGP) is a data encryption program that provides security for emails and files. It uses a system of keys—one public and one private. You can share your public key with anyone, while your private key is kept secret. When someone wants to send you a secure message, they encrypt it with your public key, ensuring only you can read it with your private key. PGP ensures confidentiality, authenticity, and integrity, making it a popular choice for protecting sensitive information in communication. It's widely used for personal privacy and data security on the internet.
