'''GNU Privacy Guard''' ('''GnuPG''' or '''GPG''') is a [[free-software]] replacement for [[Symantec Corporation|Symantec]]'s [[cryptography|cryptographic]] software suite [[Pretty Good Privacy|PGP]]. The software is compliant with the now obsoleted<ref>{{cite web |url= https://www.rfc-editor.org/rfc/rfc9580.html |title= RFC 9580 OpenPGP |date= July 2024 |publisher= IETF |access-date= 2024-12-19 |last1= Wouters |first1= Paul |last2= Huigens |first2= Daniel |last3= Winter |first3= Justus |last4= Yutaka |first4= Niibe }}</ref> {{IETF RFC|4880}}, the [[Internet Engineering Task Force|IETF]] standards-track specification of [[OpenPGP]]. Modern versions of PGP are [[Interoperability|interoperable]] with GnuPG and other OpenPGP v4-compliant systems.<ref>{{cite web |url= https://www.gnupg.org/faq/gnupg-faq.html#compatible |title= Gnu Privacy Guard |publisher= GnuPG.org |access-date= 2015-05-26 |archive-url= https://web.archive.org/web/20150429192132/https://www.gnupg.org/faq/gnupg-faq.html#compatible |archive-date= 2015-04-29 |url-status= live }}</ref> 

November 2023 saw two drafts aiming to update the 2007 OpenPGP v4 specification (RFC4880), ultimately resulting in the [https://datatracker.ietf.org/doc/rfc9580/ RFC 9580] standard in July 2024. The proposal from the GnuPG developers, which is called LibrePGP, was not taken up by the OpenPGP Working Group and future versions of GnuPG will not support the current version of OpenPGP. <ref>{{cite web |url= https://lwn.net/Articles/953797/ |title= A schism in the OpenPGP world |publisher= Linux Weekly News |access-date= 2023-12-09 }}</ref>

GnuPG is part of the [[GNU Project]] and received major funding from the [[Politics of Germany|German government]] in 1999.<ref>{{cite web |url= http://www.heise.de/newsticker/meldung/Bundesregierung-foerdert-Open-Source-24110.html |title= Bundesregierung fördert Open Source |publisher= Heise Online |language= de |date= 1999-11-15 |access-date= July 24, 2013 |archive-url= https://web.archive.org/web/20131012024601/http://www.heise.de/newsticker/meldung/Bundesregierung-foerdert-Open-Source-24110.html |archive-date= October 12, 2013 |url-status= live }}</ref>
