What is a GINA dll

What is a GINA dll, and is it possible to trap special key combinations using thi开发者_如何学Pythons dll? How can I use this in a kiosk application?

GINA handles part of the login and authentication process for interactive logins on a Windows machine for versions prior to Vista (it has since been replaced by the ICredentialProvider interface).

In general, I wouldn't advocate writing a replacement GINA (or credential provider) in .Net, as you'd inject a dependency on the .Net framework into the Winlogon process - one slip, and you could end up with a machine that refuses to boot.
