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:])
