 """ Sets up SSL configuration for the given hosts. This ensures socket is wrapped in a SSL connection, raising an exception if the SSL module can't be found. :param for_hosts: a list of tuples describing hosts this SSL configuration should be applied to :param cert_file: the path to a X509 certificate :param key_file: the path to a X509 key file :param ca_certs: the path to the a file containing CA certificates to validate the server against. If this is not set, server side certificate validation is not done. :param cert_validator: function which performs extra validation on the client certificate, for example checking the returned certificate has a commonName attribute equal to the hostname (to avoid man in the middle attacks). The signature is: (OK, err_msg) = validation_function(cert, hostname) where OK is a boolean, and cert is a certificate structure as returned by ssl.SSLSocket.getpeercert() :param ssl_version: SSL protocol to use for the connection. This should be one of the PROTOCOL_x constants provided by the ssl module. The default is ssl.PROTOCOL_TLSv1 """
