Proper installation of pyOpenSSL for Python (Windows)

I am trying to create an application that automatically updates the Google Plus spreadsheet. For this I had to configure gspread, which also requires pyOpenSSL. Without this, it throws this error:

CryptoUnavailableError: cryptocommand library unavailable

Using pip, I type the command:

pip install pyopenssl

And import using:

from OpenSSL import SSL

When I try to run the code, I get the following error:

ImportError: no module named cryptography.hazmat.bindings.openssl.binding

I tried reinstalling pyOpenSSL several times, and also tried reinstalling the cryptography dependency (as well as trying to install previous versions of pyOpenSSL).
