pyramid_hawkauth 2.0.0

This is a Pyramid authenitcation plugin for Hawk Access Authentication:

https://npmjs.org/package/hawk

To access resources using Hawk Access Authentication, the client must have obtained a set of Hawk credentials including an id and secret key. They use these credentials to make signed requests to the server.

When accessing a protected resource, the server will generate a 401 challenge response with the scheme “Hawk” as follows:

> GET /protected_resource HTTP/1.1
> Host: example.com

< HTTP/1.1 401 Unauthorized
< WWW-Authenticate: Hawk

The client will use their Hawk credentials to build a request signature and include it in the Authorization header like so:

> GET /protected_resource HTTP/1.1
> Host: example.com
> Authorization: Hawk id="h480djs93hd8",
>                     ts="1336363200",
>                     nonce="dj83hs9s",
>                     mac="bhCQXTVyfj5cmA9uKkPFx1zeOXM="

< HTTP/1.1 200 OK
< Content-Type: text/plain
<
< For your eyes only:  secret data!

This plugin uses the tokenlib library for verifying Hawk credentials:

If this library does not meet your needs, you can provide a custom callback function to decode the Hawk id token.
