Oh! Authenticated!
OAuth is a popular protocol allowing servers to offer resources owned by some user to a series of authorized clients securely. For instance, OAuth lets Twitter provide access to a user's private tweets to the Twitter client registered on their phone.
oauthenticated is a Haskell library implementing OAuth protocols
atop the popular http-client HTTP client library. The goal is to
provide a general framework for signing
'Network.HTTP.Client.Request's according to server parameters, a
simple method for executing the common 3-arm OAuth token negotiation
protocol, and a simplified API for accessing OAuth-protected
resources.
Currently oauthenticated only supports OAuth 1.0 and is in
alpha. Further testing is needed before trustworthy use can be
established. Further, OAuth 2.0 support is planned.
