If you've ever found yourself confused by the many different versions of PGP (Pretty Good Privacy) that exist (as well as the plethora of sites from which they can be downloaded), then this page is for you. What follows is a guide to help you distinguish among PGP Versions & Sources and find the version that's right for you.

Note: On October 11, 2001, Network Associates (NAI) announced that it was ending further development of the PGP product line and would be attempting to find a buyer for PGP. You can read more about NAI's decision here:

Please note that versions of PGP are still available for download at many locations around the world. Users might also be interested in the Gnu Privacy Guard (GPG), which is based on OpenPGP:

 
vs. Pay Versions

PGP (Pretty Good Privacy) is available in several different versions:

Please note that versions of PGP may be free only for personal, non-commerical, or educational use.

Different versions of PGP can be downloaded from many different locations:

PGPdisk

PGPdisk is included with PGP Desktop Security and PGP CKT versions 6.0.x and higher (incl. 6.5.x and 7.x). PGPdisk is not included with PGP Freeware versions. PGPdisk is a utility that allows you to use existing hard disk space to set up encrypted "virtual drives" in which you can store files and folders.

For more information on PGPdisk (incl. limitations, usage problems, and incompatibilities between PGP 7.x and older versions of PGP) please consult Tom McCune's PGP Questions & Answers.

PGPnet

Only PGP versions 6.5.x and 7.x include PGPnet. According to NAI, "PGPnet, a Virtual Private Network (VPN), is an easy-to-use encryption application that allows you to communicate securely and economically with other PGPnet users."

For more information on PGPnet (incl. limitations and reported usage problems) please consult Tom McCune's PGP Questions & Answers.

PGPfire

Only PGP 7.x Desktop Security includes the PGPfire firewall and IDS (Intrusion Detection System); PGP 7.x Freeware as well as earlier versions of PGP (including 6.5.8) do not.

For more information on PGP 7.x (incl. limitations, usage problems, and incompatibilities with older versions of PGP) please consult Tom McCune's PGP Questions & Answers.
