Current Status

I started building a gwt project to test oAuth. It works great. So I am going to make a user management system out of it, and include it into my other applications. (Jan/2009)

oAuth and GWT

This is my example of using oAuth in my gwt application for user authentication to protected resources. My goal, not to pass user credentials across the web. I also want to open up the possibilities of using other oAuth applications.

Available Secure Hash Functions

Hashing (digest) a consomerKey, Urlbasestring or (rpc:dataobject) can be done by different methods.

Sha1

You can also use Sha1 to get a hash/digest. I am writing the sha1.js to java so I can use it both on the server and client side with ease. I rewrote sha1.js to a java method which can be used on both the client and server side.

http://pajhome.org.uk/crypt/md5/sha1src.html - sha1.js hash functions

To include Sha1 in your project, you will need to import it in (...public>yourProject.gwt.xml)
  
  
  <script src="sha1.js"/>
