Python 3.4.4 (Windows) - backports.ssl example code (modified for Python3) does not run

[Paul Hammant]

This:

import backports.ssl as ssl
import socket

context = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
context.verify_mode = ssl.CERT_REQUIRED

conn = context.wrap_socket(socket.socket(socket.AF_INET))
conn.connect(('google.com', 443))
print(conn.getpeercert()) # modified for Python3
conn.close()

Results in:

Traceback (most recent call last):
  File "C:\Python34\lib\site-packages\backports\ssl\core.py", line 201, in _safe_ssl_call
    return getattr(sock, call)(*args, **kwargs)
