you can get some info via (undocumented?) attributes on the file handle:

 >>> import urllib
 >>> f = urllib.urlopen("https://mail.google.com/")
 >>> f.fp
<httplib.SSLFile instance at 0x00CE2508>
['issuer', 'read', 'server', 'write']
 >>> f.fp._ssl.issuer()
'/C=ZA/O=Thawte Consulting (Pty) Ltd./CN=Thawte SGC CA'
 >>> f.fp._ssl.server()
'/C=US/ST=California/L=Mountain View/O=Google Inc/CN=mail.google.com'
