AttributeError: function/symbol 'SHA256_init' not found in library 'E:\Anaconda3\lib\site-packages\Crypto\Util..\Hash_SHA256.cp38-win_amd64.pyd': error 0x7f

The attached pdf file cannot be opened with pdfplumber.

The error message: AttributeError: function/symbol'SHA256_init' not found in library'E:\Anaconda3\lib\site-packages\Crypto\Util..\Hash_SHA256.cp38-win_amd64.pyd': error 0x7f.

But I have SHA256.cp38-win_amd64.pyd in the Hash dir.

python 3.8.5, the pdf has no password

python 3.8.5

[samkit-jain]

Hi, @milozen585 I created a Python 3.8 virtual environment but could not reproduce the issue. In order to further investigate this, request you to share your conda environment file so that I can try and simulate your environment.

[samkit-jain]

Could you please run conda list and share the output. The error you are getting could be due to

1. Dependency mismatch (pdfplumber needs version X but you have version Y)
2. Some crypto library is missing

Since the issue is from pycryptodome, can you try reinstalling it as per https://pycryptodome.readthedocs.io/en/latest/src/installation.html#windows-from-sources-python-3-5-and-newer?

I will try the second way

[samkit-jain]

Thanks for sharing the list. I see that in your conda environment you have both pycrypto and pycryptodome.

pycrypto 2.6.1 py38he774522_10 defaults
pycryptodome 3.10.1 py38h2bbff1b_0 https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main

If you look at the usage of pycrypto on https://pypi.org/project/pycrypto/, you'll notice that it is imported using Crypto. pycryptodome which pdfplumber needs, is also imported using Crypto. This is because it is "an almost drop-in replacement for the old PyCrypto library". I believe that your issue will be resolved by removing pycrypto from your environment.

[milozen585]

Thank you very much, problem is solved! I reinstall anaconda because it is too slow to remove pycrypto, and then there is no pycrypto and it works!
