python-codext's Issues

using Codext guess / Codext rank gives an error

When I run it on linux and try to use "codext guess" or "codext rank" I get an error message saying:

# echo "3yZe7d" | codext rank
Traceback (most recent call last):
  File "/usr/local/bin/codext", line 8, in &lt;module&gt;
    sys.exit(main())
  File "/usr/local/lib/python3.9/dist-packages/codext/__init__.py", line 184, in main
    args.include, args.exclude = __format_list(args.include), __format_list(args.exclude, False)
AttributeError: 'Namespace' object has no attribute 'include'

UU decoding raises an exception in some cases

During handling of the above exception, another exception occurred:

base64 unexpected behavior

Soo I was doing this ctf for which I thought I might need to perform some steg attacks. I ended-up installing StegoLSB which require tinyscript which require python-codext. BUT to my mistake I did this outside of a virtualenv.

Long story short, I eventually had to base64 decode a PDF, which despite my different attempts seemed empty. This was until I realised that calling base64 -d didn't call the beloved /usr/bin/base64 but the ~/.local/bin/base64 of python-codext.

Now the issue,

The script seems to be utf8 encoding the output (without reason) and this whether we redirect the output to a file or not.

As an example I get:

head -c 100 /tmp/a|base64 -d|hexdump -C
00000000  25 50 44 46 2d 31 2e 34  0a 31 20 30 20 6f 62 6a  |%PDF-1.4.1 0 obj|

00000020  29 0a 2f 43 72 65 61 74  6f 72 20 28 c3 be c3 bf  |)./Creator (....|

Instead of the expected:

base64.b64decode("JVBERi0xLjQKMSAwIG9iago8PAovVGl0bGUgKP7/KQovQ3JlYXRvciAo/v8AdwBrAGgAdABt")
b'%PDF-1.4\n1 0 obj\n<<\n/Title (\xfe\xff)\n/Creator (\xfe\xff\x00w\x00k\x00h\x00t\x00m'

Namespace error

Getting this error:

Any ideas? I installed codext with pip. Thanks.

pip 22.3 / python 3.10 warning on install

Looks like there's a warning on the installation method via pip:

pip install codext

  DEPRECATION: codext is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559
