JCMathlib on another chips

[sanchaberliansyah17]

Hi Teams, I want to use Jcmathlib applet on Chinnesse chip's .. Do you know what all things should i collect the information of chip and send it to you so we can configure a new operation support chip type ?
because actually my chip support keygeneration ,ecdh agreement , and anything like P71 . but i cannot use your unittest class ,, it stops add HwAdd function and any other else.

Hi @sanchaberliansyah17 - it is good that your card supports these ECC algorithms, hat is baseline. But it may not be sufficient as we use them in somewhat non-standard way and card sometimes do not allow specific usage (e.g., setting public RSA exponent to 2). Therefore, it is not just matter of supported algorithms, but also their behavior in edge-cases. You may try to run jcalgtest: https://www.fi.muni.cz/~xsvenda/jcalgtest/ to obtain more details about your card, but at the end, it may require custom specific debugging.

Also, try to change card type here: OperationSupport.getInstance().setCard(OperationSupport.SIMULATOR); // TODO set your card - maybe different card profile will work.

Attention: Be prepared that you may also permanently block your card while trying to find working configuration (do not do this if you have only single card you cannot afford to loose).
