testing smart card minidriver

Question

i test my sc minidriver with certutil tool

certutil -scinfo 
or
certutil -delkey -csp "Microsoft Base Smart Card Crypto Provider" "80df03d4-70f9-4b9b-a5d4-f43e2022b3a2"
"80df03d4-70f9-4b9b-a5d4-f43e2022b3a2" is GUID of the container created by base smart card csp in cmck test.

both commands report the same error.
0x80090016  Keyset does not exist

from my minidriver log, i see that it stoped at CardReadFile("cardcf").
here is the data on my card at that moment:
"cardcf"  6 bytes   0x000001000300
"cmapfile" under "mscp"  86 bytes 
0x390064003200380064003800370066002D0064003500340065002D003400
6100610031002D0039006500330035002D00330038003100330065003800
3300330032006400390063000000000000000000030000040000

i cannot see anything wrong with data cache file.
Can anybody give me some help????

Answer 1

CryptAcquireContext with CRYPT_DELETEKEYSET returns NTE_BAD_KEYSET.
CryptAcquireContext with CRYPT_NEWKEYSET returns NTE_EXISTS.
i think maybe it's related to permissions, but what is the access permission to a smart card?

Answer 2

Get a look at the cmck.exe program.
