Summary

InformationCard-C provides a cross-platform C library, allowing consumption of Information Cards by a Relying Party. The library is low-level, meant to be easily adapted to many environments and languages.

1.0.1 Source

This is the first release of the InformationCard-C library.

InformationCard-C is a low-level library for processing of submitted identity information based on the Information Card profile. This library is meant to be used for integration into websites, as well as for integration support for higher-level languages, web servers and application frameworks.

In parallel with this release, SourceID has published a PHP extension leveraging this library, as well as a drupal module integration Single Sign-on and automatic registration into the Drupal CMS system. These are both available for download here.

Description

Windows CardSpace technology is part of the Microsoft initiative for providing secure authentication for the Internet Age. Through the UI paradigm of Information Cards, the user is presented with a simple, consistent way to manage and securely present their identity to various distributed, heterogeneous systems. This is meant to be done as easily as the user presents different forms of authentication from the identification cards on their physical person, and forms an important part of the Identity Metasystem

Within CardSpace there are three software components:
  • The Identity Selector, which presents and allows choosing from acceptable forms of authentication
  • The Identity Provider, which provides cards to users for them to use in authenticating to various systems
  • The Relying Party, which requests from a selector that specific information to be securely supplied from an identity provider.

CardSpace is used both as a system to authenticate web application requests, and to secure web services interactions through smart clients.
