OAuth often seems complicated and difficult-to-implement. There are several prominent libraries for handling OAuth requests, but they all suffer from one or both of the following: * They predate the OAuth 1.0 spec, AKA RFC 5849. * They predate the OAuth 2.0 spec, AKA RFC 6749. * They assume the usage of a specific HTTP request library. OAuthLib is a generic utility which implements the logic of OAuth without assuming a specific HTTP request object or web framework. Use it to graft OAuth client support onto your favorite HTTP library, or provider support onto your favourite web framework. If you're a maintainer of such a library, write a thin veneer on top of OAuthLib and get OAuth support for very little effort.
