Public Key Encryption Support

[Carlosinfl]

I am being asked to research and find a way for people in my office to be able to encrypt their emails using PGP or OpenPGP. I did some Google action and found GnuPG (GPG) and looks like that is something I would like to move towards however I am not sure where to begin. I can't understand if GPG is something I setup on a stand alone server, my current production email server, or is something that is done on the client side alone.

Has anyone ever done anything like this on a system running a Linux email server (Postfix)?

Thanks for any info!

PGP is generally kept strictly client-side. Have a look at the enigmail extension for thunderbird if you're interested in ease of use. Google finds some guides.

Yep, GnuPG work on the client side and integrates into email clients. Thunderbird uses Enigmail:

If you are using windows, here is a good suite of programs to use. It contains all you need:

You will find plugin's for outlook in the suite. Works with OpenPGP too.

If you are using linux, as this is a kinux forum, use your appropriate package mananger and install GnuPG. Also, there are various GUI key managers for KDE or Gnome.

Hope this helps
