hsoz (hackage): 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.  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.
