## WSS Listener
##
## Add a WSS Listener
##--------------------------------------------------------------------
## Note: This is an example of how to configure this feature
##       you should copy and paste the below data into the emqx.conf for working

## The WSS listener supports all the fields listed in listeners.ws.conf.example
## only the WSS-specific fields are shown here

## Note: Modifying the 'wssname' to what you need
listeners.wss.wssname {
    ## false to disable this
    enable = true

    ## Port or Address to listen on
    ## Default: 8084
    bind = 8084 ## or with an IP, e.g. "127.0.0.1:8084"

    ## PEM format certificates chain file
    certfile = "data/certs/cert.pem"

    ## PEM format private key file
    keyfile = "data/certs/key.pem"

    ## Enable or disable peer verification
    verify = verify_none  ## use verify_peer to enable

    ## if `verify' is ebabled, whit true, the connection fails if the client does not have a certificate to send
    fail_if_no_peer_cert = false

    ## Enable TLS session reuse
    reuse_sessions = true

    ## Maximum number of non-self-issued intermediate certificates that can follow the peer certificate in a valid certification path
    depth = 10

    ## Which versions are to be supported
    versions = [tlsv1.3, tlsv1.2]

    ## TLS cipher suite names
    ## Note: By default, all available suites are supported, you do not need to set this
    ciphers = ["TLS_AES_256_GCM_SHA384","TLS_AES_128_GCM_SHA256"]

    ## Allows a client and a server to renegotiate the parameters of the SSL connection on the fly
    secure_renegotiate = true

    ## Log level for SSL communication
    ## Type: emergency | alert | critical | error | warning | notice | info | debug | none | all
    log_level = notice

    ## Hibernate the SSL process after idling for amount of time reducing its memory footprint
    hibernate_after = 5s

    ## Forces the cipher to be set based on the server-specified order instead of the client-specified order
    honor_cipher_order = true

    ##  Setting this to false to disable client-initiated renegotiation
    client_renegotiation = true

    ## Maximum time duration allowed for the handshake to complete
    handshake_timeout = 15s
