1. Select card Manager
2. Send the following APDU command
>> 80 CA 00 66

Thanks for your answer,My friend!
But how can I select Card manager ? Or shall I know the AID firstly?

@Jsine

Send SELECT command W/O AID to select card manager
That is
00 A4 04 00 00

I have sent APDU and receive:
<<80 CA 00 66
>>66 4C 73 4A 06 07 2A 86 48 86 FC 6B 01 60 0C 06 0A 2A 86 48 86 FC 6B 02 02 01 01 63 09 06 07 2A 86 48 86 FC 6B 03 64 0B 06 09 2A 86 48 86 FC 6B 04 02 55 65 0B 06 09 2B 85 10 86 48 64 02 01 03 66 0C 06 0A 2B 06 01 04 01 2A 02 6E 01 02 90 00

I usually read the response data of command INITIALIZE UPDATE, for example:

Code: Select all

<<80 50 00 00 08 8A 34 E5 AF 41 76 DA 3E 1C
>>00 00 00 00 00 00 00 00 00 00 FF 02 00 03 B5 00 CF 85 24 1E C3 86 54 3B 8C 6C 43 EC 90 00

SCP is 0x02
response is struct as following:
SCP01: Key diversification data (10 bytes) + Key information (2 bytes, KVN + SCP identifier) + ...
SCP02: Key diversification data (10 bytes) + Key information (2 bytes, KVN + SCP identifier) + ...
SCP03: Key diversification data (10 bytes) + Key information (3 bytes, KVN + SCP identifier + SCPi) + ...

I have a cheap smart card reader for Windows but it needs some drivers to be used by applications.
Maybe inside there is an STM32?
