Calling just pyconcrete-admin should have a more friendly error message:

hi ,
Running pyconcrete files gives me the following error "ValueError: bad marshal data (unknown type code)"

I am using Mac machine .

I have compiles script with following code:
pyconcrete-admin.py compile --source=main.py --pye

and running the file with
pyconcrete main.pye

I'm using python (Python 2.7.15)

I have installed pyconcrete with setup.py.

It looks like it is pretty easy to add support for multiple compile sources. Change argument parser and loop over sources with same logic as it is right now in compile function. If you want I can try to make pull request.

zipapp makes multiple Python files as a bundle to be easy distributed. However when the pye file is bundled into the zipapp, it can't be found. Here is a minimal demo:

$ cat add_cols/app.py
import pyconcrete
import sys
from mylib import add2col

def main():
    inp = sys.argv[1]
    out = sys.argv[2]
    print(f'read file {inp}, and convert to file {out}')
    add2col(inp, out)

if __name__ == '__main__':
    main()

$ cat add_cols/mylib.py
import pandas as pd

def add2col(inpfile: str, outfile: str):
    inp = pd.read_csv(inpfile)
    inp['cola'] = inp['colb'] + inp['cola']
    inp.to_csv(outfile, index=False)

$ cat demo.csv
cola,colb
1,2
1,2
1,2
1,2

## run the plain Python file version:
$ python -m zipapp add_cols -m 'app:main'   # create a zipapp with plain Python file
$ python add_cols.pyz demo.csv res.csv   # the result file 'res.csv' is created properly

## replace mylib.py with encrypted version and run again:
$ cd add_cols
$ pyconcrete-admin.py compile --source=mylib.py --pye
$ rm mylib.py
$ cd ..
$ python -m zipapp add_cols -m 'app:main'   # create a encrypted version zipapp
$ python add_cols.pyz demo.csv res.csv       # run again

Thanks for help.

Hi, I am currently looking at the many options to protect my source code from being "easy" to reverse engineer.

I have some experience with pyinstaller, which can be really helpful to manage and simplify the packaging of many modules that I use, so I can quickly send a zipped folder to my customers, who usually have no programming knowledge of any kind.

Is there an option, or a hack / work-around to get pyconcrete to work as a stand-alone, without having Python installed on the computer?

    code = marshal.loads(data[magic:])
    m = self.new_module(fullname, self.full_path, self.pkg_path)
    sys.modules[fullname] = m
    exec(code, m.__dict__)

这个存成pyc还是能反编译吧

First, thanks for the great library!

I added celery to the example project you had, and celery's autodiscover_tasks failed to discover my celery tasks.pye files.

Turns out that celery uses the builtin imp package to check if tasks.py exists in all django apps, at app/tasks.py. In particular, it uses imp.find_module() described here https://docs.python.org/2/library/imp.html#imp.find_module

Sadly, imp.find_module doesn't find .pye files, such as tasks.pye.

Celery code: https://github.com/celery/celery/blob/120770929f4a37c5373a378b75b5c41a99702af9/celery/utils/imports.py#L90

My workaround was to use pyconcrete-admin.py ... -i tasks.py and have tasks.py simply star import an encrypted module (as no one will try to find that one ;) ).

Again, no pressure, but it will be great if we could have a hook for that library as well.

I'm just signaling this here, with a keyword Celery in case anyone else tumbles on this issues.

Hi,

Thx for your effort.

I have two question/suggestion:

1 - My main python includes some other python modules so I wonder can we also compile other modules which is included by main module so it can safely use it ?

2 - Can we change the extansion .pye to something else ? its also another protection . So viewer not understand at first place the pyconcrete is used ?

Best

Hi it's possible to use it for reusable apps?
I followed this guide https://docs.djangoproject.com/en/2.2/intro/reusable-apps/

Everything works fine and I've built pip packages. I want to protect my code so I've installed pyconcrete in main project and executed 'pyconcrete-admin compile etc'.
It works and gave me pye files so I tried 'pyconcrete-admin release' and pyconcrete created a tar.gz packag. But if I extract the code is in clear. How can I encrypt this code?

I am trying to use Electron as a GUI to run python scripts inside as child-processes.

Would it be possible to encrypt all .py files to .pye then run it in Electron?

Since .pye file has to be executed by pyconcrete.exe, I am guessing that I have to include pyconcrete.exe and run the codes when the process starts.

I am trying to distribute Electron apps to the users who have no Python installed.

But then I have to compile python codes with PyInstaller, which doesn't seem to be possible with .pye files.

Is there any way to accomplish both pyconcrete encryption and making the codes executable in Electron?

I did successfully encrypt in my development laptop but how will deploy my encrypted code to other laptop/pc?

What I tried so far is install the pyconcrete in the other pc/laptop but its asking me again the passphrase which it will defeat the purpose.

Pyconcrete is can't working with python 3.

Installation and compilation worked with no errors.

pyconcrete-admin.py compile --source=main.py --pye

At runtime I get this error

main.pye -p 0.5 -n 0.5 -d 0
SyntaxError: Non-ASCII character \xf7 in file main.pye on line 1...

The main.py file has the encoding defined as UTF-8 and has no non-ascii characters.
I'm using python 3.5, OS is Raspbian.

when you install pyconcrete using pip==9.0.3:
$ pip install pyconcrete --egg --install-option="--passphrase=<your passphrase>"

this warning is showed on the console

DEPRECATION: --egg has been deprecated and will be removed in the future. This flag is mutually exclusive with large parts of pip, and actually using it invalidates pip's ability to manage the installation process.

I can't install pyconcrete using pip-10.0.0b2. I get this error:

pip 10.0.0b2 from /var/lib/jenkins/workspace/neo-assets-api-encrypted-ubuntu1604/.venv/local/lib/python2.7/site-packages/pip (python 2.7)

  pip install [options] [-e] <local project path> ...
  pip install [options] <archive url/path> ...

no such option: --egg

I have definition in the beginning of my python code :

RESET = "\033[0;0m"
RED   = "\033[1;31m"
BLUE  = "\033[1;34m"
CYAN  = "\033[1;36m"
GREEN = "\033[0;32m"
BOLD    = "\033[;1m"
REVERSE = "\033[;7m"

and in my of my function :

def on_connect(client, userdata, flags, rc):
    print(RED ,"** Kozmos bizimle ** Connected flags" + str(flags) + "result code " \
                 + str(rc) + "client1_id " , RESET)

I compiled with

pyconcrete-admin.py compile --source=_mqt_p.py --pye

and when I run ti gives :

log: Caught exception in on_connect: name 'RED' is not defined

any idea ?

Could you please tell me the location of key information stored? If it locates on same machine, would it be possible for someone to look over and be able to decrypt the code?

    def load_module(self, fullname):
        if fullname in sys.modules:  # skip reload by now ...
            return sys.modules[fullname]

        data = decrypt_buffer(self.data)  # decrypt pye
        print('----------------------------')
        print(data)   #### plaintext
        print('-------------------------------')

Since result of decrypt_buffer is plain, we can reverse the whole source code?

Hello dear developer. I've just used an django example, you've provided and it works!
But when i try to run my own django project (after it was encrypted)

Is that is a problem of your package or my app?

It looks like pyconcrete do not support python 3.7, which is newest stable version of cpython.

How do I uninstall pyconcrete. I tried using pip but now it throws an error.

When i try to protect some python sdk with pyconcrete, i just cannot deploy protected python sdk on another pc because python version might be unmatched. But as for python sdk, it might be deployed on a lot of pc of which python version cannot be control, so, is there any way to solve this problem?

I'm looking for ways to encrypt my code, compile it and lock it to a user's computer. Will I also be able to compile my script into an exe without a problem even if I use your encryption?

Hi,

I have strange errors . :Is pyconcrete support multithreading python ?

ie :

i am imported 👍

import sqlite3 as lite

but it gives .

Running pyconcrete files gives me the following error "ValueError: bad marshal data (unknown type code)"

This happens with any file since I did a reinstall of pyconcrete to change the secret password. Before I did the reinstall I deleted all pyconcrete traces from the machine and deleted the generated pye files. Afterwards I ran the setup,py script and set a new passphrase, then recompiled the .py files to .pye file with following command

pyconcrete-admin.py compile --source=file.py --pye

and running the file with

pyconcrete file.pye

I'm using python (Python 2.7.12 (default, Dec 4 2017, 14:50:18) This is set as the machine default.

I use Mingw64+Msys2 to compile pyconcrete for Python 3.4.4 |Anaconda 2.3.0 (64-bit)

for fib.py file

def fib(n):
    if n<=1:
        return 1
    else:
        return fib(n-1) + fib(n-2)

is coded into pye as
python pyconcrete-admin.py compile --source=fib.py --pye

but test.py

import pyconcrete

import fib

for i in range(10):
    print ('fib(%2i) = %2i' %  (i, fib.fib(i)))

says

Thanks for your awesome work, which helps me a lot, but I still find something I can't understand. I use pyconcrete-admin.py to encrypt my all .py file except main.py, but when I run my code without import pyconcret in main.py, it can still run correctly, can you tell me why this happens, thanks anyway.

Is there any support of pyconcrete to ignore directory? I had my venv in the same directory as of django root, and it tries to encrypt my venv as well.

I'm using pyconcrete as library using the example given in the README.

My project has the following structure:

.
└── myproject
    ├── main.py
    ├── pyconcrete
    └── src
        ├── module1.pye
        ├── module2.pye
        └── module3.pye

What is the process to decrypt module1.pye, module2.pye, etc, given that the passphrase is know?

Now, suppose I distribute myproject to end user.

What you be the process for them to decrypt module1.pye, module2.pye, etc?

py_content has been released in Py_DECREF(py_args)

Hello,

I like to know if is possible to encrypt also a Django/Celery project ?

Thanks

It is not possible install pyconcrete under armbian in the venv. Setuptools, wheels are upgraded.

I am encrypting a project using pyconcrete but in venv. Now I'm trying to drop all the venv in another pc/laptop. When I run the code for that it gives me threading error and pushing the whole thing on the local interpreter. /usr/lib/python/threading.py

Hello Falldog,

Thanks a lot for your amazing work.
I found out that I couldn't use pip anymore on my machine. I struggled during days to find why, and it seems that pyconcrete brings some issue for its latest versions (since it create a .pth file to auto-import itself...)

However, this bug only concerns some distribution.
Here is a code that will allow you to reproduce the bug on different environment : pyconcrete_corrupts_python.tar.gz

For example, on Debian-jessie + Miniconda 4.0.5 + pyconcrete (#commit >= 095e760) => Bug
For Debian-jessie + Python2.7 + pip9.0.9 + pyconcrete => There is no bug

I will continue to work on it during my free time and keep you informed (I may will come up with a pull request if I can fix it by myself... ;) )

I compile pyconcrete again, however, this time

R:\pyconcrete>py3 test.py

R:\pyconcrete>e:\prg\py\Anaconda3_64\python.exe test.py
Assertion failed!

Program: e:\prg\py\Anaconda3_64\python.exe

Expression: PyBytes_Check(py_plain_obj)

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

any chance you could write up a guide on how i could compile pyconcrete.so for android/arm32
