The latest release of NSspi is v0.2.1.
Version 0.2.0 adds the ability to authenticate using provided username/password credentials.
**Please note** that v0.2.0 introduces a small change in the design that breaks backwards compatibility with previous verisons.
Version 0.2.1 is a minor bugfix release that improves impersonation.

## Introduction ##
This projects provides a C# / .Net interface to the Windows Integrated Authentication API, better known as SSPI (Security Service Provider Interface). This allows a custom client / server system to authenticate users using their existing logon credentials. This allows a developer to provide Single-Sign-On in their application.
This project provides a C# / .Net interface to the Windows Integrated Authentication API, better known as SSPI (Security Service Provider Interface). This allows a custom client / server system to authenticate users using their existing logon credentials. This allows a developer to provide Single-Sign-On in their application.
## Overview ##
The API provides raw access to authentication tokens so that authentication can be easily integrated into any networking system - you can send the tokens over a socket, a remoting interface, or heck even a serial port if you want; they're just bytes. Clients and servers may exchange encrypted and signed messages, and the server can perform client impersonation.
