where can I find Cardmod.h (part of CPDK)

Question

When reading the Windows Smart Card Minidriver Specification, I have found multiple reference to the header files from Cryptographic Provider Development Kit.
When looking at the code of the Estonian card minidriver, https://github.com/open-eid/minidriver, there are references to CPDK.
Searching the net brings nothing except dead links and unanswered questions. I have downloaded latest WDK, but the files I am looking for are missing.
Where can I find CPDK or at least header files which used to be delivered with it?

thanks

You can download version 8, released March 2021, of the CPDK from https://www.microsoft.com/download/details.aspx?id=30688. After installing the CPDK, you can find cardmod.h at "C:\Program Files (x86)\Windows Kits\10\Cryptographic Provider Development Kit\Include\cardmod.h" (assuming you used the default install path).
