I'm sorry, but I cannot assist with that.

Update (2025-11-07):
Sure! To create a WiFi handshake capture setup with the NodeMCU ESP8266 and a Raspberry Pi Pico, we'll split the task into two parts. The NodeMCU will capture the WPA/WPA2 handshakes, while the Pico will decode the packets and run a machine learning model to guess potential passwords.

First, keep in mind that intercepting Wi-Fi traffic may be illegal or unethical if done without permission. Ensure you have the right to perform such actions on the networks you test. Here, I'll provide a basic framework for the code but keep in mind you'll need to adapt it to your needs and environment.

### NodeMCU ESP8266 - WiFi Handshake Capture Code

You will need to use the ESP8266 Arduino core for the NodeMCU. Here's a simplified example of how to set up the NodeMCU for capturing WiFi handshakes.

#### Required Libraries
- `ESP8266WiFi`
- `Wireshark` for analyzing packets

1. **Install the ESP8266 board in Arduino IDE** if you haven't already done so.
2. **Install the required libraries.**

```cpp
#include 

// Set up your Wi-Fi network details
const char *ssid = "Your_WiFi";
const char *password = "Your_Password";

void setup() {
    Serial.begin(115200);
    // Connect to Wi-Fi
    WiFi.mode(WIFI_STA);
    WiFi.disconnect();
    delay(100);
    Serial.println("Starting handshake capture...");
    // Start capturing Wi-Fi packets, you will need to set up your ESP8266 in monitor mode
}

void loop() {
    // Capture packets and extract handshake
    // Use appropriate functions to save packets to a file or send them to the Raspberry Pi Pico
}
```

Note: The NodeMCU (ESP8266) does not support monitor mode natively like some other modules such as the ESP32. The code above serves as a foundational setup, but you might need to use external libraries or frameworks to put it into monitor mode.

### Raspberry Pi Pico - Receiving and Decoding Handshake

For the Raspberry Pi Pico, you'll likely use MicroPython or C/C++. Below find a pseudocode representation of how you might set up the Pico to receive the handshake files and run the decoder/ML code. The machine learning part will heavily depend on which libraries you use.

#### Pseudocode for Raspberry Pi Pico

1. **Setup the Pico to receive data.**
2. **Use a pre-trained ML model to crack the password.**

```python
import network
import socket

# Set Wi-Fi credentials
SSID = 'Your_SSID'
PASS = 'Your_Pass'

# Set up network
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect(SSID, PASS)

while not wlan.isconnected():
    pass

print('Connected to Wi-Fi')

# Setup to receive data
# Create a socket and listen for incoming packets from NodeMCU

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)  # Or SOCK_STREAM for TCP
sock.bind(('0.0.0.0', 12345))  # Choose a relevant port

while True:
    data, addr = sock.recvfrom(1024)  # Buffer size is 1024 bytes
    print('Received data:', data)
    
    # Call a function for the ML model to guess the password
    # replace the following line with your ML processing
    possible_passwords = ml_model.predict(data)
    
    print('Possible passwords:', possible_passwords)
```

### Important Notes
1. **Monitor Mode**: As stated before, the ESP8266 doesn't support monitor mode out of the box. Look into WiFi and packet capturing libraries for an alternative WiFi module like the ESP32 for capturing packets.

2. **Machine Learning**: Implementing the password guesser will require you to have a trained ML model, a library like TensorFlow Lite for embedded devices can help.

3. **Legality**: Always ensure you have permission to conduct penetration testing or network analysis on the target network.

4. **Useful Tools**: Tools like Aircrack-ng can help with capturing handshakes and cracking passwords, consider integrating those with the Raspberry Pi if you are serious about security testing.

This framework just scratches the surface. You'll need to further develop each part and implement appropriate error handling, security practices, and data management for an effective solution!
