Contrary to Python's implementation of SSLSocket, it allows you to chain multiple TLS connections together. It's particularly useful if you need to implement TLS within TLS. The class supports most of the socket API operations. zssl.SSLContext�None)� ssl_context�returnc C s t | d�std��dS )z� Raises a ProxySchemeUnsupported if the provided ssl_context can't be used for TLS in TLS.
