GNU Privacy Guard (GnuPG or GPG) is a free-software replacement for Symantec's cryptographic software suite PGP. The software is compliant with RFC 4880, the IETF standards-track specification of OpenPGP. Modern versions of PGP are interoperable with GnuPG and other OpenPGP v4-compliant systems.[4]

November 2023 saw two drafts aiming to update the 2007 OpenPGP v4 specification (RFC4880). The proposal from the GnuPG developers is called LibrePGP. [5]

GnuPG is part of the GNU Project and received major funding from the German government in 1999.[6]
