On Windows there is a problem installing pycrypto in Python 3.6, it's a known issue, see https://stackoverflow.com/questions/41843266/microsoft-windows-python-3-6-pycrypto-installation-error.
There was a bug reported to pycrypto which results in the conclusion that PyCrypto is dead. Switch to PyCryptodome.
So the software requirements needs to be updated, maybe other docs too?
Thanks,
Mickey
