今天学习了一下Passport：
MSDN上的文档：
http://msdn.microsoft.com/library/default.asp?url=/downloads/list/websrvpass.asp
http://www.microsoft.com/net/services/passport/developer.asp
PassportSDK 的几部分：Passport Manager, Passport Crypt, Passport LookupTable, and Passport Factory
how to implement Microsoft® .NET Passport:
1。注册：https://www.netservicesmanager.com/ 联系方式，URL等
2。开发：安装passport SDK
downloading and installing encryption keys
some additional configuration
3。请求一个（Compliance Review）Request a Compliance Review of Your Site，需要到 netservicesmanager 上签署一个PassportService的Contract，然后等待验证。
4。Launch the live site: download an encryption key
configure your environment and encryption key
install the .NET Passport client software on each of your live servers
如果地址改变，还要到 netservicesmanager 上更改；
SGK：提供了Passport的brand（商标）；
