Re: Java card supporting RSA4096
You have very very limited option if you want RSA-4096 bit operations. Here is the only one (but very hard to obtain) hardware that supports JavaCard and 4096-bit RSA. I wish you good luck and all the best attempting to obtain these hardware as thee company is known to be very picky on their custom...

Question about Map implementation
As I know, JavaCard 2.2 doesn't have a Map implementation. Java SE HashMap has an hashing function and its variable size could probably cause out of memory errors. What about a constant size Map with a simple hashing relative to its constant size?

Can anyone help me with this? i want the applet to return a simple byte array along with the status word 9000 (w...
