Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications. Phil Zimmermann developed PGP in 1991.
PGP and similar software follow the OpenPGP standard, whose current specification is RFC 9580. RFC 9580 obsoleted RFC 4880, the earlier OpenPGP message-format specification. Modern versions of PGP are interoperable with GnuPG and other OpenPGP-compliant systems.
