Pyinstaller with encryption results in TypeError cannot be passed to C code

glycoaddict Source

I want to compile an exe with encryption (to prevent "casual" decompiling).

I am able to compile with Pyinstaller v2.1 in one exe file using a spec file, when I don't use encryption.

But, when I add the following line to the .spec file to introduce encryption (pycryptodome ):

block_cipher = pyi_crypto.PyiBlockCipher(key='1234567812345678')

I end up with this error: File "c:\users\username\test-env\lib\site-packages\Crypto\Util\_raw_api.py", line 151, in c_uint8_ptr raise TypeError("Object type %s cannot be passed to C code" % type(data)) TypeError: Object type <class 'str'> cannot be passed to C code

The log leading up to the error was: 90328 INFO: Appending 'datas' from .spec 90371 INFO: checking PYZ 90372 INFO: Building PYZ because out00-PYZ.toc is non existent 90373 INFO: Building PYZ (ZlibArchive) C:\Users\choom.000\Documents\masstools_clean\obf\build\graphms\out00-PYZ.pyz Traceback (most recent call last): File "C:\Users\choom.000\test-env\Scripts\pyinstaller-script.py", line 11, in <module> load_entry_point('PyInstaller==3.3.1', 'console_scripts', 'pyinstaller')() File "c:\users\choom.000\test-env\lib\site-packages\PyInstaller\__main__.py", line 94, in run run_build(pyi_config, spec_file, **vars(args)) File "c:\users\choom.000\test-env\lib\site-packages\PyInstaller\__main__.py", line 46, in run_build PyInstaller.building.build_main.main(pyi_config, spec_file, **kwargs) File "c:\users\choom.000\test-env\lib\site-packages\PyInstaller\building\build_main.py", line 791, in main build(specfile, kw.get('distpath'), kw.get('workpath'), kw.get('clean_build')) File "c:\users\choom.000\test-env\lib\site-packages\PyInstaller\building\build_main.py", line 737, in build exec(text, spec_namespace) File "<string>", line 20, in <module> File "c:\users\choom.000\test-env\lib\site-packages\PyInstaller\building\api.py", line 98, in __init__ self.__postinit__() File "c:\users\choom.000\test-env\lib\site-packages\PyInstaller\building\datastruct.py", line 161, in __postinit__ self.assemble() File "c:\users\choom.000\test-env\lib\site-packages\PyInstaller\building\api.py", line 133, in assemble pyz = ZlibArchiveWriter(self.name, toc, code_dict=self.code_dict, cipher=self.cipher) File "c:\users\choom.000\test-env\lib\site-packages\PyInstaller\archive\writers.py", line 184, in __init__ super(ZlibArchiveWriter, self).__init__(archive_path, logical_toc) File "c:\users\choom.000\test-env\lib\site-packages\PyInstaller\archive\writers.py", line 59, in __init__ self._add_from_table_of_contents(logical_toc) File "c:\users\choom.000\test-env\lib\site-packages\PyInstaller\archive\writers.py", line 84, in _add_from_table_of_contents self.add(toc_entry) # The guts of the archive.

Seems like it is a problem with the "key" which is class 'str'. I tried to change in the .spec file the key = 'a123456712345678' or u'1234567812345678' but still have the problem.
