PGP for Outlook Open Source with Source Code

Prerequisites for Outlook 2007 (see 2010, 2013 below)

First of all, get a working copy of GPG is required, so visit the GnuPG download page, scroll down and download the Windows installer version or windows version. 

Windows installer version is located here, you can install PA (personal Assistant), but it never worked on my computer. But this is a GUI to your user keys.
If everything has gone correctly, you can now open a command prompt and type gpg --version and gpg --list-keys to see the version and your keys (which would be empty if you're using it for the first time).
Visit the Getting Started section of the GnuPG handbook to generate your own key if this is your first encounter for instructions. You need a private public key for latter in the install.
gpg --gen-key

To install this quickly, 

choose 4) RSA and key size of 2048 default will do, or 4096 for better security, and continue, it's pretty logical.


There are two main areas in the plugin, functionality for sending a mail (sign/encrypt) and for retrieving a mail (verify/decrypt).
At the moment only plain text emails are supported. No HTML mail or attachments, that's for a future version :)

See Cumps Consulting blog for the remainder of the install article ...

GnuPG addin for Outlook 2007

Here is the Github project :

NOTE: To get this to work in Vista/7 you have to run the installer as administrator. Find your command shell in the run menu, right click and select run as administrator. Then do msiexec -i "path\and\filename.msi". That should get you past the impersonation difficulties.
