Re: JC30M48CR

JC10M24R: KeyPair generation

I have question about the new card JC10M24R .
There is an indication "KeyPair not supported" on the left of RSA512~2048. If it doesn't support KeyPair generation, how does it generate the key?
Thanks

the size of JCRE

Due to the requirement of our item, I want to compare javacard in many aspects. I also have to get the size of JCRE, maybe JUST an average value, but I didn't find any information about this. Do you have methods to know this? Sorry for my trivial question.
