This module was contributed by Jon Colverson. It provides a couple of helper
24
functions that allow you to use M2Crypto's implementation of HTTPSConnection
25
rather than the default version in httplib.py. The main benefit is that
26
M2Crypto's version verifies the certificate of the server.
28
To use this feature, do something like this:
30
from boto.ec2.connection import EC2Connection
32
ec2 = EC2Connection(ACCESS_KEY_ID, SECRET_ACCESS_KEY,
33
https_connection_factory=https_connection_factory(cafile=CA_FILE))
35
See http://code.google.com/p/boto/issues/detail?id=57 for more details.

from M2Crypto import SSL
38
from M2Crypto.httpslib import HTTPSConnection
40
def secure_context(cafile=None, capath=None):
42
ctx.set_verify(SSL.verify_peer | SSL.verify_fail_if_no_peer_cert, depth=9)
43
if ctx.load_verify_locations(cafile=cafile, capath=capath) != 1:
44
raise Exception("Couldn't load certificates")
47
def https_connection_factory(cafile=None, capath=None):
48
def factory(*args, **kwargs):
49
return HTTPSConnection(
50
ssl_context=secure_context(cafile=cafile, capath=capath),
52
return (factory, (SSL.SSLError,))
