25  * These headers are related to providing user Secure Streams Serialization
26  * transport implementations in user code.
27  *
28  * The default implementation uses wsi for proxy serving and connecting clients,
29  * but it's also possible to provide user implementations of the operations
30  * needed to serve on a different transport for proxy, and to connect out on
31  * the different transport for client.
32  *
33  * You can provide your own lws_sss_ops_client_t and lws_sss_ops_proxy_t to
34  * control how serialized data is transmitted and received, to use SS
35  * serialization over, eg, UART instead.
36  *
37  * This allows situations where full SS proxy services can be offered to much
38  * weker devices, without any networking stack or tls library being needed.
