NOTE MIGRATION needed
* Immediate reason for this implementation is to make it harder for our AWS keys to be compromised -- this will allow us to store them in encrypted (AES 256) form in the db, which will require ability to run mysql on the EC2 instance
* depends on a Django settings.SECRET_KEY, which for now, we might store in settings/local.py -- we could get fancier about how to serve that up
