PGP (Pretty Good Privacy)

Pretty Good Privacy (PGP) is a data encryption program that secures emails and files to keep them private. It uses a combination of symmetric and asymmetric cryptography, meaning it encrypts messages with a unique key that only the intended recipient can access. Users create key pairs: a public key, which anyone can use to send encrypted messages, and a private key, which only the receiver possesses to decrypt them. PGP helps ensure that sensitive information remains confidential and is often used for secure communications over the internet.
