PGP
PGP (Pretty Good Privacy), originally developed by Phil Zimmerman, is a high security cryptographic software application for MSDOS, UNIX, VAX/VMS, and other computers. PGP allows people to exchange files or messages with privacy, authentication, and convenience.

NOTE: You must agree to the PGP 5.0 License before installing this version of PGP on your Virtual Private Server. This version of PGP is for non-commercial use only. If you are going to use PGP for commercial use, you must purchase a license from Network Associates.

This version of PGP has also been modified so that it will work in both the virtual and non-virtual environments. Modifications have also been made to the PGP executable provided such that it will only run on our Virtual Private Servers. Please do not attempt to export this version off of your Virtual Private Server. It will not work.

An alternative to PGP is GnuPG, which has less restrictive license requirements.

Installation
Do the following, depending on your Virtual Private Servers O/S.

  • FreeBSD & Solaris [PGP 5.0]
    Connect to your Virtual Private Server via Telnet or SSH and issue these commands:

    % vinstall pgp
% rehash

  • BSD/OS Upgrade! [PGP 5.0]
    Connect to your Virtual Private Server via Telnet or SSH and issue these commands:

    % /usr/local/contrib/pgp5-install
% rehash

    You must now contact our Support Staff and have them help you complete the installation.

  • Huh?
    If you don't know the Virtual Private Server O/S, try the following:

Implementation
To generate your own public/secret key pair:

% pgpk -g

Or if you already have a public/secret key pair, you will want to add your existing keys to your Virtual Private Server's key ring:

% pgpk -a [keyfile]

To add PGP to your CGI's do something like the following:

... | pgpe -r <userid> -a -f | mail -s "Encrypted Mail" ...

Another option is the PGP version of FormMail, PGP FormMail.

Documentation
PGP is very well documented and thus very easy to use if you do your homework. All questions sent to the Support Staff with regard to PGP usage will be answered with the URL of this page.

The following PGP 2.6.2 documenation is provided for reference value.
