PGP (= Pretty Good Privacy) is another public key system written by Phil 
Zimmerman quite a while ago. The encryption used by Apple's mail is an Internet 
standard called S/MIME. PGP and S/MIME work pretty much the same, but they 
don’t  work together.

If you want to use PGP instead, I'd recommend looking at GPG, which is a free 
and open source PGP clone. It has a plugin for Apple's mail on the Mac, but you 
have to use more byzantine methods on iOS.

A problem with PGP/GPG is that you have to use a plugin and when Apple's mail 
gets updated, you have to hope the plugin will work with the new version.

I've thought of moving over to GPG because of all the revelations coming out 
about the NSA snooping. I don’t  know whether the NSA has their tendrils into 
Comodo, so all my keys might be compromised. With GPG I can make my own keys, 
so I know they're secure.
