If anyone is wondering what the new Infocard registration and login links are on my blog, let me explain. As I mentioned in my last entry, I am working on libraries to work with XMLENC and XMLDSig in PHP. Being complicated technologies, the code produced so far has been just trying to design a API that uses PHP's KISS approach before moving on to writing bindings for the XML Security Library. In order to test out the APIs I wanted to use real world scenarios, such as building a class to handle WS-Security using the routines from the API. A few months ago I came across another technology leveraging XMLENC and XMLDSig: Infocards (aka Windows CardSpace). I am getting really sick of long blog entries showing up almost in their entirety in aggregators, so I am truncating this here and you can read the full entry for the rest of the story.
