[Question] - Crypto usage

[vankk]

Hello, I was trying to use the crypto key and I came across with this thread on stackoverflow, also tried to use pip install pycrypto and didn't worked as well. Seems that the package has some issues, there is any plan to update this feature or just I may doing some wrong?!😛

Edit: nvm, just saw that the pyinstaller still requires the pycrypto and didn't updated yet.

Regards,
vankk.

If you want to use the --key argument from PyInstaller, I definitely recommend using pycryptodome instead of PyCrypto as it is safer. It has almost the same API as PyCrypto so it should work.

You can install pycryptodome using:

python -m pip install pycryptodome

Could you post an usage sample? Did a few searchs the past days and everytime that I open the the .exe returns an Failed to execute script pyiboot01_bootstrap.

Outlined in "Encrypting Python Bytecode" are some details on how to encrypt your executable contents.

I had been told that pycryptodome works with pyinstaller but when trying it myself, it appears that may not be the case. I get an error saying: zlib.error: Error -3 while decompressing data: incorrect header check.

I have noticed in PyInstallers GitHub issues that the maintainer has mentioned that --key is no longer available. I did a search for --key in PyInstallers GitHub issues and found this PR but unfortunately it hasn't been merged yet - looks promising though.

Sweet. Since this is more related to PyInstaller than this tool, I'll close the issue. If you do find an issue with this, feel free to open a new issue.
