Thinktecture Identity model has support for Eran Hammer’s Hawk authentication in the form of OWIN middleware. With ASP.NET vNext introducing a new but very similar middleware concept (changes only on the API surface and OWIN middleware can be used as-is in ASP.NET VNext apps), I took the opportunity to completely rewrite the middleware. As ASP.NET vNext is being actively developed, there could be changes and this middleware will change to react to those changes. Hence, at this point, this middleware is just for review only. Since Linus had said “Talk is cheap. Show me the code.”, I keep this blog post very short and just link to github. Your feedback is welcome.
