Hi,
I tried keypair generation using pkcs11-tool in our
card. The operation was failing. I debugged the code
and found that below code in the function
sc_pkcs15init_generate_key of opensc-pkcs11 module is
failing.
=================================================
if (!check_key_compatibility(p15card,
&keygen_args->prkey_args.key,
                 keygen_args->prkey_args.x509_usage,
                 keybits, SC_ALGORITHM_ONBOARD_KEY_GEN))
                return SC_ERROR_NOT_SUPPORTED;
==================================================
With my card check_key_compatibility function is
returning 0 and so sc_pkcs15init_generate_key function
is SC_ERROR_NOT_SUPPORTED error code.

Can you please tell me whether it is error in
opensc-pkcs11 module or it is Function as intended.

I need some other help. I am developing external card
driver to make opensc module to work with our card. I
am currently emulating pkcs#15 structures. Will it be
possible to provided operations like importing of key
pair and certificate to the card. 
Since pkcs#15 structure is emulated i want to know
whether there will be any problem in providing
importing/generation of keypair and certificate to
card. Is there any currently supported card following
this approach.

Regards,
Kamal.
