Pretty Good Privacy

Pretty Good Privacy (PGP) is a computer program that provides cryptographic privacy and authentication. PGP is often used for signing, encrypting and decrypting electronic mails (e-mails) to increase the security of e-mail communications. It was originally created by Phil Zimmermann in 1991.

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