adding PCSC support to nfcgate

[0dayfrp]

Hello, I'm trying to communicate from windows pc with Nfcgate server, I have not decided yet which is the best approach.
Can you please advise? below is an attempt I have made

import c2c_pb2.py, c2s_pb2.py
import socket
import socketserver
import struct
import sys
import datetime
from smartcard.System import readers
from smartcard.Exceptions import NoCardException

HOST = "0.0.0.0"
PORT = 5566

class PluginHandler:
# Existing PluginHandler code remains unchanged

class NFCGateClientHandler(socketserver.StreamRequestHandler):
# Existing init, log, and setup methods remain unchanged

def communicate_with_card(self, apdu):
    r = readers()
    if len(r) == 0:
        self.log("No smart card readers detected.", tag="SmartCard")
        return None

    try:
        connection = r[0].createConnection()
        connection.connect()
        response, sw1, sw2 = connection.transmit(apdu)
        return response + [sw1, sw2]
    except NoCardException:
        self.log("No smart card inserted.", tag="SmartCard")
        return None

def handle(self):
    # Existing handle setup code remains unchanged

    while True:
        try:
            # Existing code to read data from the socket remains unchanged

            # Here, integrate smart card communication
            # Convert data to APDU format if necessary
            apdu = list(data)  # Ensure it's in the correct format for pyscard
            card_response = self.communicate_with_card(apdu)
            
            if card_response is not None:
                self.log(f"Card response: {card_response}", tag="SmartCard")
                # Modify this part to send the card's response back
                # For example, you might send it directly back to the requester or to all clients in a session
                # This is a placeholder; adapt it to your needs
                self.wfile.write(struct.pack('!I', len(card_response)) + bytes(card_response))
            else:
                self.log("Error communicating with the card.", tag="SmartCard")

            # Break or continue based on your application's logic

        except socket.timeout:
            # Existing timeout handling remains unchanged

# Existing finish method remains unchanged

class NFCGateServer(socketserver.ThreadingTCPServer):
# Existing NFCGateServer code remains unchanged

if name == "main":
NFCGateServer((HOST, PORT), NFCGateClientHandler).serve_forever()
