Alrite finally i got the OpenSSL Crypto to work HealthVault. It took some Ninja hacking and quite a lot of debugging to figure out what was going wrong with signing of a xml for getting an authentication token from HealthVault. Turns out that my signing code was dead on but HealthVault didn’t quite like the white space in the “content” section. I wont belabor you more but the short of the long is that now OpenHealthVault can talk to HealthVault and get itself authenticated. As usual the code is at http://svn.vitraag.com/openhealthvault and the application in action is at http://openhealthvault.vitraag.com. Well now its time to get a user to be authenticated with HealthVault Shell and the Rails goodies, I expect these to flow rather smoothly.

My last post explained a little about challenges of OpenSSL to achieve the healthvault signing for opensource LAMP/R platforms. In this post i’m showing below an actual snippet for talking to the public methods of healthvault platform.

Sean is starting a series detailing his adventure with healthvault .NET applcations. In the same spirit i’m going to build the ruby on rails application and library through a series of posts here. The application is live at http://openhealthvault.vitraag.com and the source code is in the SVN repository at http://svn.vitraag.com/openhealthvault.
