See especially the notes on non-blocking sockets .\n\nInstances of SSLSocket must be created using the SSLContext.wrap_socket method.\n\nSSL sockets also have the following additional methods and attributes\n\nRead up to len bytes of data from the SSL socket and return the result as a bytes instance. If buffer is specified, then read into the buffer instead, and return the number of bytes read.\n\nRaise SSLWantReadError or SSLWantWriteError if the socket is non-blocking and the read would block.\n\nAs at any time a re-negotiation is possible, a call to read can also cause write operations.\n\nWrite data to the SSL socket and return the number of bytes written. The data argument must be an object supporting the buffer interface.\n\nRaise SSLWantReadError or SSLWantWriteError if the socket is non-blocking and the write would block.\n\nAs at any time a re-negotiation is possible, a call to write can also cause read operations.\n\nThe ~SSLSocket.read and ~SSLSocket.write methods are the low-level methods that read and write unencrypted, application-level data and decrypt/encrypt it to encrypted, wire-level data. These methods require an active SSL connection, i.e. the handshake was completed and SSLSocket.unwrap was not called.\n\nNormally you should use the socket API methods like ~socket.socket.recv and ~socket.socket.send instead of these methods.\n\nPerform the SSL setup handshake. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
