How do I use GNU Privacy Guard?
May 4th, 2010 | 
Author: I am using the PDG shopping cart. With it, I want to encrypt my emails so no one can see the credit card information. I have followed their instructions from http://www.pdgsoft.com/docs/Encryption.pdf but I cannot get it to work. I was able to install the PGP software and create a key, but I do not know how to use the GNU Privacy Guard. I have a windows XP computer, but I am running our website on a linux server. It says to upload the gpg.exe file to my FTP. When I do that on my linux server, it will not run. However, it will run on my windows computer. How can I install the linux version on my windows computer to upload to my linux server?

GPG.EXE won’t run because it’s a Windows program. Further, you can’t just drop the file that needs to be executed in the FTP home folder because by default FTP users don’t have the administrative access necessary to install stuff on the server. What you can do is get the program by installing the package through whatever system your distribution uses; yum for Redhat, apt-get for Ubuntu, etc.
This appears to be the part where you run into trouble:
"Note: If you are using Windows and your shopping cart is running on a UNIX machine, you will have to uncompress the -.tar.gz archive appropriately. If you need assistance obtaining the gnupg program, please contact PDG technical staff."
