Also, with regards to the question about using GPG in your email  
client. Most email clients will require a plugin of some sort. Some  
will not work with GPG at all (Don't know if the latest version of  
Windows Mail will, for example.) Last time I looked at GPG and MS  
Outlook, it was kind of a kludge as there was not a real  
"Microsoft-blessed" plugin.
