Thanks

I have two questions about Elliptic Curve Cryptography(ECC). private KeyPair keyPairA; private KeyPair keyPairB; keyPairA = KeyPair(KeyPair.ALG_EC_F2M,KeyBuilder.LENGTH_EC_F2M_113); keyPairB = KeyPair(KeyPair.ALG_EC_FP,KeyBuilder.LENGTH_EC_FP_112); Could anyone tell me what is the difference between...

Hi friends in here,

I have a question about Le in APDU command.

If I don't know how many data I will have in response, is there any special value of Le for this case?

Thanks.
