Getting a unique hardware ID with Python

Question

I have a process that requires me to identify different machines, and I\'m not sure what\'s the best way to do it. I do not want to save that ID on a text file or something,

Answer 1

For windows this seems to get same uuid every time por each device based on the MAC address:

str(uuid.uuid1(uuid.getnode(),0))[24:]

But it does not seem to keep same ID on Android 4.4.2.

Answer 2

or use bios serialnr

wmic bios get serialnumber

Answer 3

The ideal approach which I resorted to was this. It is quite fast and efficient.

hwid = str(subprocess.check_output(
    'wmic csproduct get uuid')).split('\\r\\n')[1].strip('\\r').strip()
data = requests.get(
    'https://gist.githubusercontent.com/rishav394/z/raw/x')
if hwid in data.text:
    print('Authenticated!')
    auth = True
else:
    print(hwid + ' was not found on the server.\nNot authorised!')

Answer 4

Please note that you can get the same UUID from Windows without installing any additional software with the following command:

C:\> wmic csproduct get uuid

Answer 5

You could use dmidecode.

Linux:

import subprocess

def get_id():
    return subprocess.Popen('hal-get-property --udi /org/freedesktop/Hal/devices/computer --key system.hardware.uuid'.split())

Windows:
NOTE: Requires dmidecode for Windows

import subprocess

def get_id():
    return subprocess.Popen('dmidecode.exe -s system-uuid'.split())

Cross-platform:
NOTE: Requires dmidecode for Windows

import subprocess
import os

def get_id():
    if 'nt' in os.name:
        return subprocess.Popen('dmidecode.exe -s system-uuid'.split())
    else:
        return subprocess.Popen('hal-get-property --udi /org/freedesktop/Hal/devices/computer --key system.hardware.uuid'.split())
