Hi,
I'm trying to write to a Siemens SLE4442 card, using the CT-API in Linux and a
Towitoko reader, but I can't find out how to verify the PIN.
I succesfully managed to write to the other cards I have, all I had to do was to
verify the pin as discussed in a previous discussion.
So, what APDU command shall I send before trying to write to the card? Sending the
same command as I did to the other cards results in an verification error end my tries
are decreased by one.
I read something about the PIN being BCD-encoded, how should the PIN-data that I send
look like?
I'm using a program that came with the Towitoko reader, SmartCard Explorer. It says
that my PIN is 000000.
How can I read the PIN from the card, is that even possible? And how do I get the
number of tries that are left?
Is it possible to unblock a card when I run out of tries, does that require some kind
of "super user PIN"?
In the SC Explorer app, write protected bytes are in blue color, how do I find out
which that are write protected?
Thanks, Henrik Sandberg
