Standalone binaries/executables

[decnorton]

Hi there,

We're looking at supporting encrypted files when accepting files for importing data into our application (currently we have to ask users to remove the password protection first).

This tool works great (thanks!) for decrypting on environments where python is available & the correct dependencies are installed - however I'd like to try and make our deployment as lean as possible by including a pre-compiled binary with no dependency on having Python already installed (we lack any strong Python experience in the team, so would like to avoid any problems that arise as a result).

I've had a play around with pyinstaller with limited success. It gave me an executable that I could use, however it was struggling with handling relative imports. The resulting executable was around 6MB which seems like a worthwhile sacrifice for the transportability.

I'm too much of a Python noob to figure out the pyinstaller issues, but I'm pretty confident it can be accomplished with some help!

Would you consider providing standalone binaries/executables, or perhaps even an 'official' Docker image with your releases?

Many thanks,
Dec

Thank you for your suggestions!

As for the project itself, providing standalone binaries is outside the scope for now.
The same is true for Docker images, but there are some Docker-ready Linux distributions which include msoffcrypto-tool (see https://repology.org/project/python:msoffcrypto-tool/versions).

it was struggling with handling relative imports

Sorry, I'm aware of that problem and will fix it.
I hope after the fix you will be successful with PyInstaller, but I'm not sure in particular if the cryptography library, on which msoffcrypto-tool depends, can be included in the PyInstaller-packed binaries properly.

FYI, there are some similar tools/libraries available in Java, C++, etc. (see https://github.com/nolze/msoffcrypto-tool#alternatives).

Thanks! I'll have a go at putting together a slimmed down Docker image

Import problem would be fixed by #63. (not released yet)
Also, I noticed that some relevant work has been done by pyinstaller-hooks-contrib. pyinstaller/pyinstaller-hooks-contrib#139
