I have searched around and cannot find direct documented evidence on my side that it definitely always works.
But I can find information that some customers we have do store EFS certs on SID800...I just do not know exactly
if they simply store them there, or EFS uses them directly.
-old EFS (original) cannot be done with a smart card certificate...the keys are stored on the user profile
-newer EFS can be configured to look for the key information on a smart card
Encrypting File System
-for most intents and purposes, if you have the recommended smart card drivers for the SID800
and have configured EFS correctly for smart card cert storage, it should work fine.
I do know that a few 3rd party products that do file encryption can use the certs stored on a SID800.
I will summarize by staying there is not a reason I can find why it would not work.
If you can configure EFS to use smart cards, it should work with the SID800 smart card.
