How to implement RSA 4096 algorithm in java card applet?

Post by JCaberham » Wed Jul 17, 2019 5:56 am

I want to implement RSA 4096 bit algorithm in my applet,

There is an error when I get the values of N and D parameters.

Is it need to use the extended APDU to receive APDU data?

Is the card you are using capable of 4096 RSA? If not then there is no way to make it accept it anyway. I believe the JCOP J3H145 has the capability, try using one of those.
