Seems that this is intended more for webapps or something, I intend to
use this for a client application. This means that I can't require
outside dependencies, or I risk annoying the clients (if you have
installed many open-source projects with dependencies that aren't
handled by portage/apt-get, you know what I would be doing to them).

I seriously can't believe that there isn't a single python native
crypto package. Why do they all need to have outside dependencies?
