Summarize this article for a 10 year old


GNU Privacy Guard (GnuPG or GPG) is a free-software replacement for Symantec's PGP cryptographic software suite. 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-compliant systems.[4] GnuPG is however expected to break compliance with the upcoming revision of OpenPGP and thus with other implementations that will continue to comply.[5]
