PGP in an acronym for Pretty Good Privacy. Created by Phil Zimmermann [
1], it implements a public/private key encryption environment where one is able to publish a portion of one's key publically, to be used by someone wanting to send you a private message. Only those whose keys are used to encrypt the message can, in theory, decrypt it using the software. The software has had some freely distributable portions as well as commercial portions, but it is my understanding that some parts of the idea are patented.
Members of the
FSF project, have created GNUPG,

, as a freely available and open counter-part to PGP.
