OpenPGP is an open standard for email and file encryption and digital signatures, built on PGP. It uses public-key cryptography to encrypt and sign messages, and exchanges public keys through key servers and the web of trust. GnuPG (GPG) is its best-known implementation, and it is also widely used to verify signatures on software distribution files.
