Hi Ram.,
Oberthur AuthentIC v.2.1 smartcard provides on board RSA key generation up
to 2048 bits.
It also, of cause, supports RSA exponentiation with loaded keys, the size
of which range 512 up to 2048 bits.
Regarding key loading, there is only a few number of standards, OP (Global
Platform) specifies how to load a 1024 bits RSA Public Key in order to
allow a Security Domain to perform token verification; expect that
reference, nobody (but AuthentIC application, according to my knowledge)
specifies a way to load a 1024 bit RSA CRT private key (at least 320 bytes)
or a 2048 bits key (it's definitively not specified by JavaCard ... that
doesn't specify any APDU commands).
Regarding key extraction, you can implement your own applet to do that
unless the card (and some middeware) offers an export key function.
Sylvain.
