[Dev] Automatic secure email

[Aaron Swartz]

If we use a crypto algorithm like that implemented by nistp224 (which 
is fast, simple, public domain, patent-free, cross-platform, and has 
Python bindings) then public keys are only 28 bytes. Even if we have to 
base64encode them, that's still only 38 characters, certainly short 
enough to include in the headers of every message.
