support of austrian e-card

Hi,
        
I'd like to see the Austrian e-card supported by opensc.
Since I am an
Austrian citizen I do have an e-card and a card reader. I
also tried
opensc with it and played around with it a bit. 
        
Although I am quite new to smart cards I will try as much as
I can to
achive this goal. Is there any way that you can help me, or
that I can
help you - if you are interested at all?
        
So far, I found out that the e-card is based on G&D
STARCOS 3.1 OS. This
is quite the same as 3.0 but with ecc instead of rsa. i.e.
means it
cannot generate any rsa keys but only ecc.
        
3.x is - on the other side - much more compliant to
iso7816.
Unfortunately the documentation to STARCOS 3.x disappeared
from G&D's
website.
        
As a start I modified the starcos code to match the proper
atr and
detect the card correctly. I know that is not much but it is
a start.
        
What do you think about it?
        
Regards,

Well, then the first task will be to fully support ECDSA in
opensc.

Regarding the SC OS you are right, but the ecard is the only
one with
STARCOS 3.1 as far as I know and regarding the file
structure: it is
following the pkcs#15 standard. by snooping around on the
card I found
the EF's with the certificates.

It would still make sense to contact G&D for the 3.1
specs. I'll give it
a try.
