What's the simplest way to set up a JSON-RPC server in python and make it secure? I'm very interested Pyjamas for python/javascript - but the documentation doesn't explain how to implement security with the JSON-RPC.
I've played with pyjamas a little and am currently implementing json-rpc with django.
Have you considered using ssl to secure the site. Short of implementing your own (basic) encryption routine, its probably the best way forward.
