pyOpenSSL0.13---'socket' object has no attribute 'get_peer_cert_chain'

Asked by h&m

I want to get certificate chain ,but a problem happend ,the problem is that 'socket' object has no attribute 'get_peer_cert_chain'.
I use pyOpenSSL0.13 and python3.3
the sample code named test.py:

import socket
from OpenSSL import SSL
context = SSL.Context(SSL.SSLv23_METHOD)
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
connection = SSL.Connection(context,s)
connection.connect(('www.google.com',443))
connection.setblocking(1)
try:
    connection.do_handshake()
except OpenSSL.SSL.WantReadError:
    print("Timeout")
    quit()
print(connection.get_peer_certificate().get_issuer().commonName)------>1
print(connection.get_peer_cert_chain())------------------------------------------->2

#python test.py
    print(connection.get_peer_cert_chain())
AttributeError: 'socket' object has no attribute 'get_peer_cert_chain'

step 1:success
step 2: failure

Did I ignore something?

Your code is probably picking up an older version of pyOpenSSL.

Works for me:

tmp/test-get-peer-cert-chain> python test.py
Google Internet Authority
[<X509 object at 0x7ff6f123d1b0>, <X509 object at 0x7ff6f123d1d0>]

I test two cases:
1.python 3.3 + pyOpenSSL0.13 ------->Error
2.python 2.7 + pyOpenSSL0.13 ------->OK

Maybe it is a bug.
