twisted.internet._sslverify._setAcceptableProtocols : API documentation

Called to set up the OpenSSL.SSL.Context for doing NPN and/or ALPN negotiation.

Parameters	context	The context which is set up. (type: `OpenSSL.SSL.Context`)
	acceptableProtocols	The protocols this peer is willing to speak after the TLS negotiation has completed, advertised over both ALPN and NPN. If this argument is specified, and no overlap can be found with the other peer, the connection will fail to be established. If the remote peer does not offer NPN or ALPN, the connection will be established, but no protocol wil be negotiated. Protocols earlier in the list are preferred over those later in the list. (type: `list` of `bytes`)

Function	protoSelectCallback	NPN client-side and ALPN server-side callback used to select the next protocol. Prefers protocols found earlier in `_acceptableProtocols`.
Function	npnAdvertiseCallback	Undocumented

def protoSelectCallback(conn, protocols): (source)

Parameters	conn	The context which is set up. (type: `list` of `bytes`)
