LibraryNotFoundError('Error detecting the version of libcrypto') on 0.5.7

[MaxRozendaal]

I installed version 0.5.7 with pipx:

pipx install git+https://github.com/skelsec/msldap.git

When running msldap the following error is thrown:

Traceback (most recent call last):

oscrypto.errors.LibraryNotFoundError: Error detecting the version of libcrypto

It seems that the version 1.3.0 of oscrypto on PyPi does not yet support Python 3.11.

Setting up a venv and installing oscrypt from source with pip install 'oscrypto @ git+https://github.com/wbond/oscrypto.git' resolves the issue. This is also mentioned as an issue on the oscrypto GitHub page: wbond/oscrypto#78.

Even though this error is caused by a dependency I thought i'd drop this here for other people running into the same issue.

Hello, thank you reporting.
This issue was known for a while now, but as you stated it's a 3rd party package and fixing this is out of my control as of now.

Thank you for the headsup.
Installing the new version of the asyauth library from github or pip should fix the issue.
