Hi François,
Thank you for replying!

I don't think that the matter is in reader-pcsc.c, I think you should
have a look on Portuguese eID in command " pin_cmd " the
SC_PIN_CMD_CHANGE
is probably slip in two parts SC_PIN_CMD_VERIFY + the
SC_PIN_CMD_CHANGE
just disable the SC_PIN_CMD_VERIFY when reader is pinpad capability...
If I disable it, then OpenSC will try to build an SC_PIN_CMD_CHANGE
apdu with "old pin, new pin, new pin" - but the card specification
does not allow it. Meanwhile, I was trying to understand the PC/SC V2
spec part 10, but it's not very detailed. I was able to find a
document by Gemalto [1] that says this, on page 13:
bConfirmPin: 0x03
bNumberMessage: 0x03
Messages seen on Pinpad display: Enter Pin, New Pin, Confirm Pin
This is the case is reader-pcsc.c as it can be seen on the code:
pin_modify->bConfirmPIN = 0x03; /* bConfirmPIN, all */
pin_modify->bEntryValidationCondition = 0x02; /*
bEntryValidationCondition, keypress only */
if (slot->capabilities & SC_SLOT_CAP_DISPLAY)
pin_modify->bNumberMessage = 0x03; /* 3 messages (because
bConfirmPIN = 3), all default. Could be 0xFF too */
else
pin_modify->bNumberMessage = 0x00; /* No messages */
On the document, there are other options explained. One looks promising:
bConfirmPin: 0x01
bNumberMessage: 0x02
Messages seen on Pinpad display: New Pin*, Confirm Pin*
*In these two cases, old PIN is not asked by the Pinpad but do not
forget to put the old
PIN value in the APDU command.
So, I changed the code in reader-pcsc.c:
pin_modify->bConfirmPIN = 0x01;
pin_modify->bEntryValidationCondition = 0x02; /*
bEntryValidationCondition, keypress only */
if (slot->capabilities & SC_SLOT_CAP_DISPLAY)
pin_modify->bNumberMessage = 0x02;
else
pin_modify->bNumberMessage = 0x00; /* No messages */
And now it works as expected :)
Of course, by doing this I'm breaking all other cards and it's not
very nice. Is there any way (through a flag in structure or something)
that we can signal part10_build_modify_pin_block() to adapt its
behavior depending on the type of card?

Can anyone help?
Thank you.
