Active Directory smartcard authorization

Im looking how to perform smart card authentication against AD from C# client application. I need to make logon into ap开发者_开发百科plication using the smart card. Could somebody give me clue where to find API for this? Thanks.

you can call logonuser with serialized credential:

• the hash of the certificate will become the username
• the PIN of the smart card will become the password

But to get the certificate, you will have to enumerate the cryptoapi containter then access the certificate using CryptGetKeyParam(KP_CERTIFICATE)
