Bad idea. I have card which has 3 certificates: SigG, Auth, Enc. Unfortunately
pins for SigG and Enc locked, so I test only Auth.
For compute digital signature: SigG use sign (Simon post), Auth use decryption
(my card), Enc probably use decryption.
So, it doesn't work for all certificates.

Maybe little emulation.
Acoording to documentaion, key ids for certificates:
Auth - 0x01, Enc - 0x0085.
So in:
////
static int
cardos_set_security_env(sc_card_t *card,
const sc_security_env_t *env,
int se_num){
if(env->key_ref[0] == 0x01 ||
env->key_ref_len == 2 &&
env->key_ref[0] == 0x00 &&
env->key_ref[1] == 0x85)){
env->operation = SC_SEC_OPERATION_DECIPHER;
...
}
...
}
