"Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is often used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications. It was created by Phil Zimmermann in 1991." - https://en.wikipedia.org/wiki/Pretty_Good_Privacy

"GNU Privacy Guard (GnuPG or GPG) is a free software replacement for Symantec's PGP cryptographic software suite. GnuPG is compliant with RFC 4880, which is the IETF standards track specification of OpenPGP. Modern versions of PGP and Veridis' Filecrypt are interoperable with GnuPG and other OpenPGP-compliant systems." - https://en.wikipedia.org/wiki/GNU_Privacy_Guard
