I use a free one from Thawte <http://www.thawte.com/home.html>. The  
cert and keys are stored in your keychain, so I guess any app "could"  
use it. The recipient doesn't need to do anything to receive your  
signed email—though some servers block the email because of the  
"attachment," calling it an unknown virus. However,  encrypting is a  
little more complicated since the recipient must have your public key  
in order to decrypt your msg. There's plenty of in depth info at the  
above link.
  	 Useful? You decide that. I'm _sure_ my email is going to my  
recipient "as written" since it's digitally signed. And encrypted if  
I chose.
ciao,
Vince
