> So this seems to be a function that just gets the certificate?  You need to be careful with this since a server could perfectly decide to send a different certificate depending on the client hello it receives. (...) In any case, you should always use SSLv23, stop supporting anything else.

I don't understand. You say that depending on the protocol, you may get a different certificate, and then that we should stop supporting multiple protocol. Does it mean that you ask to remove a Python feature?

Even if it is technically possible to return a different certificate, I don't think that much servers will return a different certificate if the client uses SSLv23 instead of SSLv3.
