Encrypt data by storing it within a Python script that pretends to just be "obfuscated"

Project description

Obfuscatron

Encrypt data by storing it within a Python script that pretends to just be "obfuscated"

Features

  • Store binary or text data within the identifiers of a Python script
  • Obfuscated Python script can be executed (see notes below)

Currently, Obfuscatron is able to store data within the following Python syntax:

  • Variables
  • Class Names
  • Function Names
  • Type Hint Identifiers

Installation

$ pip install obfuscatron
$ pip install "git+https://github.com/Pebaz/obfuscatron"

Usage

$ obfuscatron FILE.py encode DATAFILE OUTFILE.py
$ obfuscatron OUTFILE.py decode DATAFILE

Example

Given this Python file to store some data:

custom_int_name = int


def function_add(first_number: custom_int_name, second_number: custom_int_name):
    return first_number + second_number


def function_sub(first_number: custom_int_name, second_number: custom_int_name):
    return first_number - second_number


def function_mul(first_number: custom_int_name, second_number: custom_int_name):
    return first_number * second_number


def function_div(first_number: custom_int_name, second_number: custom_int_name):
    return first_number / second_number


def function_mod(first_number: custom_int_name, second_number: custom_int_name):
    return first_number % second_number


def function_exp(first_number: custom_int_name, second_number: custom_int_name):
    return first_number ** second_number


custom_float_name = float


def func_float_add(first_num: custom_float_name, second_num: custom_float_name):
    return first_num + second_num


def func_float_sub(first_num: custom_float_name, second_num: custom_float_name):
    return first_num - second_num


def func_float_mul(first_num: custom_float_name, second_num: custom_float_name):
    return first_num * second_num


def func_float_div(first_num: custom_float_name, second_num: custom_float_name):
    return first_num / second_num


def func_float_mod(first_num: custom_float_name, second_num: custom_float_name):
    return first_num % second_num


def func_float_exp(first_num: custom_float_name, second_num: custom_float_name):
    return first_num ** second_num


custom_bool_name = bool


def function_and(first_bool: custom_bool_name, second_bool: custom_bool_name):
    return first_bool and second_bool


def function_or(first_bool: custom_bool_name, second_bool: custom_bool_name):
    return first_bool or second_bool


def function_xor(first_bool: custom_bool_name, second_bool: custom_bool_name):
    return first_bool != second_bool

Turn this data:

name = Earth
radius = 39000000
terrestrial = True
foo = "😂"

name = Mars
radius = 12349282382
terrestrial = True
foo = "😂😂"

name = Jupiter
radius = 4300012323
terrestrial = False
foo = "😂😂😂"

Into this "obfuscated" Python file containing that data:

$ obfuscatron python-file.py encode original-data.txt obfuscated-python-file.py

Result:

_1bdf0020ac0e6cb = int

    return _rp9q563626 != _0eqmvftj17s

To get it back:

$ obfuscatron obfuscated-python-file.py decode get-original-data-back.txt

Notes

Since Python is a fully dynamic language, any section of code within a Python script can lookup specific variables, classes, and functions by name. Scripts using this feature of Python will not work after being obfuscated by Obfuscatron because Obfuscatron changes the names of all the identifiers in the script. To properly use Obfuscatron, use an input script that works (to not draw attention to the variable names storing data), and ensure that no dynamic name introspection occurs during runtime.
