6.6.13 Perform a VERIFY operation.
Perform a VERIFY operation without doing anything else. This may be
used to initialize a the PIN cache earlier to long lasting
operations. Its use is highly application dependent:
Perform a simple verify operation for CHV1 and CHV2, so that further
operations won't ask for CHV2 and it is possible to do a cheap check on
the PIN: If there is something wrong with the PIN entry system, only the
regular CHV will get blocked and not the dangerous CHV3. idstr is
the usual card's serial number in hex notation; an optional fingerprint
part will get ignored.
There is however a special mode if idstr is suffixed with the
[CHV3]: In this case the Admin PIN is checked if
and only if the retry counter is still at 3.
