简介

GnuPG (GNU Privacy Guard) is the complete and free implementation of the OpenPGP standard. It lets you encrypt and sign data and communications using public-key cryptography, manage your keys, and build a web of trust. GnuPG underpins encrypted email, signed software releases and countless security tools, and is available as a command-line utility plus graphical front-ends such as Kleopatra and GPG Suite. As a battle-tested, audited and ubiquitous tool, it remains the foundation of open-source encryption for files, email and code signing.
