Pretty Good Privacy (PGP)

Pretty Good Privacy (PGP) is a data encryption program that provides cryptographic privacy and authentication for data communication. It uses a combination of symmetric and asymmetric encryption to secure emails and files. With PGP, each user has a pair of keys: a public key, which can be shared with anyone to encrypt messages, and a private key, which is kept secret to decrypt those messages. This ensures that only the intended recipient can read the content. PGP helps to protect sensitive information from being accessed by unauthorized individuals, enhancing security in digital communications.
