[Twisted-Python] 'module' object has no attribute 'optionsForClientTLS'

[Orbitus]

I am trying to execute the check_server_certificate.py and I am getting this error… can you guys help me figure out whats going on? its the exact sample code on the website running on Ubuntu 14.04.


Here is the error output:

Traceback (most recent call last):
  File "check_server_certificate.py", line 28, in <module>
    task.react(main, sys.argv[1:])
  File "/usr/lib/python2.7/dist-packages/twisted/internet/task.py", line 867, in react
    finished = main(_reactor, *argv)
  File "check_server_certificate.py", line 6, in main
    options = ssl.optionsForClientTLS(hostname=host.decode('utf-8'))
AttributeError: 'module' object has no attribute 'optionsForClientTLS'


Here is the code (check_server_certificate.py):


from __future__ import print_function
import sys
from twisted.internet import defer, endpoints, protocol, ssl, task, error

def main(reactor, host, port=443):
    options = ssl.optionsForClientTLS(hostname=host.decode('utf-8'))
    port = int(port)

    class ShowCertificate(protocol.Protocol):
        def connectionMade(self):
            self.transport.write(b"GET / HTTP/1.0\r\n\r\n")
            self.done = defer.Deferred()
        def dataReceived(self, data):
            certificate = ssl.Certificate(self.transport.getPeerCertificate())
            print("OK:", certificate)
            self.transport.abortConnection()
        def connectionLost(self, reason):
            print("Lost.")
            if not reason.check(error.ConnectionClosed):
                print("BAD:", reason.value)
            self.done.callback(None)

    return endpoints.connectProtocol(
        endpoints.SSL4ClientEndpoint(reactor, host, port, options),
        ShowCertificate()
    ).addCallback(lambda protocol: protocol.done)

task.react(main, sys.argv[1:])
