I am trying to use the PIV card for BitLocker Drive Encryption. The smart card has an encryption certificate and authentication certificate. I get an error message that "A certificate suitable for BitLocker cannot be found on your smart card". My encryption certificate has no Enhanced Key Usage field and the key usage attribute is set to Key encipherment . As per the Microsoft documentation http://technet.microsoft.com/en-us/library/dd875548(WS.10).aspx it should work, but it does not. Any ideas/suggestions?Thanks

Hi, Please also refer to the following article to change Certificate attributes: Locking a Data Drive with a Smart Card (Windows 7) If there is any error message, please upload it Thanks, Novak
