Configuration.handleTLSClientHello()

Description

Appends a handleTLSClientHello filter to the current pipeline layout.

A handleTLSClientHello filter calls back user scripts when a TLS client hello message is found in the input stream.

INPUT - Any types of Events.
OUTPUT - Same Events as input.

The user function that gets called will have an object as parameter. The object has these fields:

serverNames - An array of server names from SNI
protocolNames - An array of protocol names from ALPN

This filter passes everything down unaltered. It doesn't change anything in the event stream.

Syntax

pipy()
  .pipeline()
  .handleTLSClientHello(
    ({ serverNames, protocolNames }) => onClientHello()
  )

Parameters

handleTLSClientHello(handler)

handler

A callback function that receives SNI and ALPN information in the TLS client hello message passing through the filter. The parameter the callback function receives is an object containing the following fields:

serverNames - An array of server names from SNI
protocolNames - An array of protocol names from ALPN

Return Value

The same Configuration object.
