This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
Oz Haskell Implementation
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.
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.
This is an in-progress experiment in implementing the protocol in Haskell.
- Iron: complete
- Hawk: complete
- Oz: under construction.
- Example web application: under construction.
Please note: until the example application is built, this library cannot be considered “battle-tested”.
