Get Card Certificate Command
This command generates and provides the card basic. This command should be used after each GET MANUFACTURER and before the OPEN SECURE CHANNEL command in order to securely get the card ephemeral public key for the channel encryption key exchange.
def get_card_certificate(nonce: int):
card.get_card_certificate(nonce)
# For example:
import secrets
random_number = secrets.randbits(64)
get_card_certificate(random_number)
