Pretty Good Privacy (PGP) standard

Pretty Good Privacy (PGP) is a method for securing digital communication, mainly emails, through encryption. It uses a pair of cryptographic keys—a public key to lock (encrypt) messages and a private key to unlock (decrypt) them. This ensures that only the intended recipient can read the message, maintaining confidentiality. PGP also provides digital signatures, allowing recipients to verify the sender's identity and confirm that the message hasn't been altered. Widely used for privacy and authentication, PGP combines strong encryption with digital verification to promote secure and trustworthy electronic communication.
