obscurepy
A tool for obscuring, or making python source code difficult to read.
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.
