OAuth C# Basic Library

October 18, 2007 at 2:59 am · Filed under Code, OAuth

We have just released a basic C# library for OAuth (yay!), an open protocol to allow secure API authentication in a simple and standard method from desktop and web applications.

Yedda is part of the OAuth working group (among, with Twitter, Pownce, Ma.gnolia, Google, Jaiku, Flickr, SixApart and other notable individuals) and has contributed to the creation of the specification (we try to get involved and help whenever we can).

The basic C# library produces the OAuth signature which is needed in both server side and client. Additional details on the library, how to use it and its extendability mechanism can be found on this blog post on my blog.

For more information on OAuth check out the OAuth web site and blog. You can also read a great Beginner’s guide to OAuth by Eran Hammer-Lahav (If you are up to it, you can always take a look at the spec :-) ).

    Very cool!! Look forward to playing around with this (would also love a stable openid c# server library).

    Steven: I have a client/server OAuth library I’ve written a few months back in C# that you might find interesting… http://code.google.com/p/devdefined-tools/wiki/OAuth
