Play With Windows Registry using Python

 

Code Example

---

Note**: Only For Windows User

Suppose we are creating one windows application and that has some license key for what is the best place to keep that key so that no can hack it or reuse it.

Let's start .....

We will be creating a Function for a different purpose 

Example :

# test.py

import winreg as wreg

def store_data_in_windows_registry():

    my_key = "my-demo-key"

    data = "Test data"

    key = wreg.CreateKey(wreg.HKEY_CURRENT_USER, my_key)

    wreg.SetValue(key, my_key, wreg.REG_SZ, data)

    print("Data Set in Register")

def get_data_from_windows_registry():

    my_key = "my-demo-key"

    try:

        key = wreg.OpenKey(wreg.HKEY_CURRENT_USER, my_key)

        return wreg.QueryValue(key, my_key)

    except:

        return "No Data Found"

def clear_data_from_windows_registry():

    my_key = "my-demo-key"

    key = wreg.OpenKey(wreg.HKEY_CURRENT_USER, my_key)

    try:

        wreg.DeleteKey(key, my_key)

    except:

        print("Deleted From Regisrty")

# running 

store_data_in_windows_registry()

print("Trying fetch Data from Registry")

print(get_data_from_windows_registry())

print("Clearing Registry")

clear_data_from_windows_registry()
