I'm trying to run the test code and here's what I got

 File "test.py", line 1, in <module>

Any thoughts?

Hmmm.... this is pretty odd.

What version of cryptography.io are you using here? What version of OpenSSL is cryptography.io using? Maybe there is a version conflict on your system? Either way, I don't believe this to be a pyUmbral issue.
