cryptographic error

[ljmetzger]

Since the application was working before, you seem to have some kind of configuration problem. Please note that the PYPI version of pyopenssl was updated to 18.0 on May 16, 2008. Again using Python 2.7 and Windows 10 I successfully ran the following code:

from OpenSSL import crypto
from cryptography.x509 import certificate_transparency

print("done")

This might not help much since you are on a Linux system.

You might want to consider giving your copy of Python 2.7 the Death Penalty, and reinstall Python 2.7 and all packages you need.
