* We have a choice of 3 authentication options

* The channel can be run in 2 modes

* 1. clear
* 2. tls
*
* And TLS can use 2 types of credentials
*
* 1. anon
* 2. x509
*
* We thus have 9 possible logical combinations

* 5. tls + anon + vnc
* 6. tls + anon + sasl

* 9. tls + x509 + sasl
*
* These need to be mapped into the VNC auth schemes
* in an appropriate manner. In regular VNC, all the
* TLS options get mapped into VNC_AUTH_VENCRYPT
* sub-auth types.
*
* In websockets, the https:// protocol already provides
* TLS support, so there is no need to make use of the
* VeNCrypt extension. Furthermore, websockets browser
* clients could not use VeNCrypt even if they wanted to,
* as they cannot control when the TLS handshake takes
* place. Thus there is no option but to rely on https://,
* meaning combinations 4->6 and 7->9 will be mapped to
* VNC auth schemes in the same way as combos 1->3.
*
* Regardless of fact that we have a different mapping to
* VNC auth mechs for plain VNC vs websockets VNC, the end
* result has the same security characteristics.
