This may interest some out there. Learning all the cryptography stuff is cool, and we don't necessarily like others reading our emails. Here's a video explaining more and goes through some simple steps to get you started.
I have created keys using GPG on the Linux terminal, added my account to Thunderbird, and installed the Enigmail extension. I have added a link to my public key, so that anyone may now encrypt emails with my public key and send them on to me. Please include your public key as an attachment if you would like me to use yours in response to your emails. I plan to sign all my emails with my key to show official correspondence.
