Known implementations: twisted.protocols.tls.TLSMemoryBIOProtocol
A TLS based transport that supports using ALPN/NPN to negotiate the protocol to be used inside the encrypted tunnel.
| Attribute | negotiatedProtocol | No summary |
Inherited from ISSLTransport:
| Method | getPeerCertificate | Return an object with the peer's certificate info. |
Inherited from ITCPTransport (via ISSLTransport):
| Method | loseWriteConnection | Half-close the write side of a TCP connection. |
| Method | abortConnection | Close the connection abruptly. |
| Method | getTcpNoDelay | Return if TCP_NODELAY is enabled. |
| Method | setTcpNoDelay | Enable/disable TCP_NODELAY. |
| Method | getTcpKeepAlive | Return if SO_KEEPALIVE is enabled. |
| Method | setTcpKeepAlive | Enable/disable SO_KEEPALIVE. |
| Method | getHost | Returns IPv4Address
or IPv6Address. |
| Method | getPeer | Returns IPv4Address
or IPv6Address. |
Inherited from ITransport (via ISSLTransport, ITCPTransport):
| Method | write | Write some data to the physical connection, in sequence, in a non-blocking fashion. |
| Method | writeSequence | Write an iterable of byte strings to the physical connection. |
| Method | loseConnection | Close my connection, after writing all pending data. |
The protocol selected to be spoken using ALPN/NPN. The result from ALPN
is preferred to the result from NPN if both were used. If the remote peer
does not support ALPN or NPN, or neither NPN or ALPN are available on this
machine, will be None.
Otherwise, will be the name of the selected protocol as bytes.
Note that until the handshake has completed this property may incorrectly
return None:
wait until data has been received before trusting it (see
https://twistedmatrix.com/trac/ticket/6024).
