"Pretty Good Privacy (PGP) is a data encryption and decryption computer 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 to increase the security of e-mail communications. It was created by Phil Zimmermann in 1991. PGP and similar products follow the OpenPGP standard (RFC 4880 ) for encrypting and decrypting data." -- Wikipedia
