Questions tagged [gnupg]

GNU Privacy Guard (GnuPG / GPG) is a cryptography suite implementing secret-key cryptography and public-key cryptography. GnuPG is the GNU project's complete and free implementation of the OpenPGP standard as defined by RFC4880. Use this tag for programmatic use of the GPG tool or its library. Questions about direct usage of the GPG tool or its graphical pendents belong on Super User.

GNU Privacy Guard (GnuPG) is a cryptography application. It implements a combination of conventional symmetric-key cryptography for speed, and public-key cryptography for ease of secure key exchange.

GnuPG is the GNU project's complete and free implementation of the OpenPGP standard as defined by RFC4880.

GnuPG allows encryption and signing of data and communication. It features a versatile key management system as well as access modules for all kinds of public key directories. The gpg command line tool has features for easy integration with other applications. A wealth of front-end applications and libraries are available.
