Error when installing: AttributeError: module 'lib' has no attribute 'OpenSSL_add_all_algorithms'

[cgc]

I get the following error when executing my psiTurk server after upgrading to psiTurk 3.3.1 and installing into a new virtualenv (Python 3.10):

...
  File "/Users/carlos/proj/exp/env/lib/python3.10/site-packages/psiturk/experiment.py", line 10, in <module>
    import requests
  File "/Users/carlos/proj/exp/env/lib/python3.10/site-packages/requests/__init__.py", line 95, in <module>
    from urllib3.contrib import pyopenssl
  File "/Users/carlos/proj/exp/env/lib/python3.10/site-packages/urllib3/contrib/pyopenssl.py", line 46, in <module>
    import OpenSSL.SSL
  File "/Users/carlos/proj/exp/env/lib/python3.10/site-packages/OpenSSL/__init__.py", line 8, in <module>
    from OpenSSL import crypto, SSL
  File "/Users/carlos/proj/exp/env/lib/python3.10/site-packages/OpenSSL/crypto.py", line 3268, in <module>
    _lib.OpenSSL_add_all_algorithms()
AttributeError: module 'lib' has no attribute 'OpenSSL_add_all_algorithms'

Following this Stack Overflow post, I was able to resolve the issue by pinning cryptography to 38.0.4 in my requirements.txt. For a more general fix in psiTurk, the answer notes the issue can be fixed by upgrading openssl.

I'm not certain there is an active maintainer if this project at the moment. There are several pull requests outstanding...

I'm not super active on this these days but happy to delegate PR merging to someone with experience and desire to see a few things merged in!

I'm a full time developer, and maintain an internal independent fork of psiturk; I'm willing to do it, at least for a while.
