Installation

This command will install obscurepy:

python -m pip install obscurepy

I would recommend installing it in a virtual environment as opposed to globally:

python -m venv venv
source venv/bin/activate
python -m pip install obscurepy

Limitations

As this program is still in active development, there are many limitations. Below are some examples of what obscurepy can do. If it isn't in the example, obscurepy probably can't do it. This example serves to represent the ablities of each release. This example should be functional, both the original source and obscured source should execute.

An example:

class FirstClass:
    pass


class SecondClass(FirstClass):
    # this is a comment
    class_variable = 6

    def __init__(self, param_1):
        self.my_property = param_1

    def class_function(self, param_1, param_2):
        self.prop_1 = param_1
        self.prop_2 = param_2


def first_function():
    def with_another():
        c = 42
        return c
    return with_another()

def second_function(param_1, param_2, param_3):
    d = 'string'
    return d + str(param_1)

def third_function():
    e = 100.0
    return e

a = FirstClass()

b = SecondClass(1)

print(first_function())

print(second_function(1, 2, 3))

print(third_function())

a = SecondClass(1)

a.class_function(1, 2)

first_function()

class _0x3fe:
    pass

class _0x452(_0x3fe):
    _0x5bb = int('0x6', 16)

    def __init__(_0x1aa, _0x2a1):
        _0x1aa._0x4ca = _0x2a1

    def _0x5db(_0x1aa, _0x2a1, _0x2a2):
        _0x1aa._0x251 = _0x2a1
        _0x1aa._0x252 = _0x2a2

def _0x5ed():

    def _0x50c():
        _0x63 = int('0x2a', 16)
        return _0x63
    return _0x50c()

def _0x641(_0x2a1, _0x2a2, _0x2a3):
    _0x64 = ''.join([chr(x) for x in [115, 116, 114, 105, 110, 103]])
    return _0x64 + str(_0x2a1)

def _0x5e0():
    _0x65 = float.fromhex('0x1.9000000000000p+6')
    return _0x65
_0x61 = _0x3fe()
_0x62 = _0x452(int('0x1', 16))
print(_0x5ed())
print(_0x641(int('0x1', 16), int('0x2', 16), int('0x3', 16)))
print(_0x5e0())
_0x61 = _0x452(int('0x1', 16))
_0x61._0x5db(int('0x1', 16), int('0x2', 16))
_0x5ed()

Usage

The following command can be used to obscure a single file:

obscure --filepath=my_module.py

The following command can be used to obscure a multi file project:

obscure --project_dir=my_project

Alternatively, you can specify an output directory for both single file and multi file obscuring:

obscure --filepath=my_module.py --output_dir=desired_output_directory

obscure --project_dir=my_project --output_dir=desired_output_directory

Disclaimer

Obscurepy is no substitution for standard security practices. Obscurepy will not protect your code, nor will it protect the constants within your code. Python is an interpreted language and by nature anyone with access to your source code can reverse engineer it or simply extract any constant replacement to determine the value. Obscurepy is not meant to be used with security in mind. Obscurepy can make your source code difficult to read and it may deter people from trying. It will not stop any determined person from figuring out what your code does. I suggest looking into PyArmor if a more sophisticated method of obfuscation is required.
