I'm looking to do some Route53 interaction within a Twisted-based program. I'm extending txAWS to support Route53 and looking at how to authenticate the requests. txAWS some some rudimentary signature code but it looks like it will take a lot of work to make it usable for a new set of APIs.
boto3 includes an implementation of the various authentication systems - but ties it closely to the http library it uses internally (requests). I could probably construct some kind of adapter between the two interfaces to be able to use this code, but ...
Has anyone else implemented (and open sourced) AWS Auth v2 in a way that makes it easily reusable by a Twisted-based HTTP client?
