Hi.
Some of the crypto functions may require a
significant increase in the WWT on the reader.
If you let me know what reader you are using I
can see if this will be a problem and fix it
before it exists.
Could you please explain me what "WWT" stands for,
because I don't understand what the problem is.
However, I'm using a Towitoko's CHIPDRIVE.
WWT stands for "Work Waiting Time". This is a time
span that can be set from the PC which is used to
wait for a response of the card after sending a
command. If the WWT has times out, a failure is
assumed.
Crypto functions in smartcards need some time, so
small WWT values can cause the PC to suppose an error
even if there is none (the card is still working on
the crypto).
Bye, Mike
