When I finishe exported the private key blob from PKCS12
file, and I want to import the private key blob and
certificate to the system certificate store, what should I
do next?
And Who can tell me about the data struct about private
key blob, and how can I know about the private key blob
kind(is it a signature key pair or a exchange key pair)?

Thanks a lot.
