Comment:

 Please take a look at these two patches.

 The first refactors the connection to directly use OpenSSL functions
 through M2Crypto. Python's `ssl.wrap_socket` doesn't provide enough
 access: we can `getpeercert` but as far as I can tell there's no way to
 get the certificate chain.

 The second patch iterates over the certificate chain and looks for a
 match. It also uses a sha1sum copied directly from the Chromium source
 code.
