ImportKey method has non-standard behaviour #6

Closed kuhy closed 4 years ago

The problem is in the following code snippet:

if (key_size != LENGTH_EC_FP_256)
    ISOException.throwIt(key_size);

This is non-standard behavior that violates ISO7816. For instance, when I send the following APDU to the card, the response will be 9000 (= command correct). However, this command is invalid (wrong length).
