Issue

When attempting to install PAT, I encounter the following error: AttributeError: module 'lib' has no attribute 'OpenSSL_add_all_algorithms'.

Resolution

To resolve this issue:

• Execute your command in a virtual environment using pipenv (i.e. pipenv run pip3 install panther_analysis_tool)
  or

• Install the dependency in your local environment by running pip3 install -U pyopenssl cryptography

• Cause

This issue arises because your command attempts to execute in your local Python environment, which lacks the necessary dependencies.
