Security – Short, easy to understand explanation of GPG/PGP for nontechnical people?

Does anyone have a link to a good, but short (1-2 paragraphs) explanation of the benefits of using GPG/PGP signing and encryption for Email focused at non-technical readers? That is, why would someone care about email being signed?

I’ve looked but all I ever find are deeply technical, jargon filled documents; perhaps my Google-fu is failing me.

Solution:

Why Use PGP? — probably fits your size.  

 

PGP is useful for two things: 1. Privacy and Security, and 2. Authenticity.
 By privacy, I mean that you can prevent people from seeing things. For example, you can encrypt an email to someone, or encrypt a file with a list of passwords.
 By Authenticity, I mean that you can ensure a message was sent/written by the person you think it was, and that it wasn’t modified by a third party. Of course, these two can be combined.
