Pretty Good Privacy

Pretty Good Privacy (PGP) is a data encryption and decryption computer program that provides cryptographic privacy and authentication for data communication.

Description

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.

PGP and similar software follow the OpenPGP standard (RFC 4880) for encrypting and decrypting data.
