hsoz: Iron, Hawk, Oz: Web auth protocols

[ authentication, bsd3, library, web ] [ Propose Tags ]

__ __

hsoz is a Haskell implementation of the Iron, Hawk, and Oz web authentication protocols. These protocols originate from the OAuth2 standardisation process, but are designed to be simpler to implement for the common case of web applications.

This module is based on the Javascript code and documentation by Eran Hammer and others. A fair amount of Hammer's descriptive text has been incorporated into this documentation, as well as the cool logos.


In the words of their principal designer:

Iron is a cryptographic utility for sealing a JSON object using symmetric key encryption with message integrity verification. Or in other words, it lets you encrypt an object, send it around (in cookies, authentication credentials, etc.), then receive it back and decrypt it. The algorithm ensures that the message was not tampered with, and also provides a simple mechanism for password rotation.

Hawk is an HTTP authentication scheme using a message authentication code (MAC) algorithm to provide partial HTTP request cryptographic verification.

Oz is a web authorization protocol based on industry best practices. Oz combines the Hawk authentication protocol with the Iron encryption protocol to provide a simple to use and secure solution for granting and authenticating third-party access to an API on behalf of a user or an application.


The top-level Network.Iron, Network.Hawk, Network.Oz modules contain further instructions on their usage. There are also some example server and client programs within the project git repository.
