Request for information to enroll a User Certificate and Private key into the Virtual smart Card

[monojeets]

I am looking for some information or pointers on how can i enroll a User Certificate and a Private Key into the VSC so that it can be used for Authentication.

I have successfully configured and started VPCD and VICC. I can see the VSC is now inserted into the virtual reader.

• TS = 3B --> Direct Convention

  TA(1) = 13 --> Fi=372, Di=4, 93 cycles/ETU

Possibly identified card (using /usr/share/pcsc/smartcard_list.txt):

Would anyone have any pointers on how can i now enroll Cert and Private Key into this VSC? I think i need to use APDU commands but a little more details on the smart card structure or any other documentation will be really helpful.

Any help appreciated.

Thanks
