In ecflow 4.0 we had an option for SSL support. However this was a compile time decision.
It meant that the GUI could not look at SSL and non-SSL servers at the same time.
In ecflow 5.1.0 the default is to allow both to be used, providing the open ssl libraries were found.
Hence we can decide at run time.
Use ECF_SSL environment variable to enable encrypted communication
export ECF_SSL=1 ecflow_server # or use ecflow_start.sh -s ecflow_client --stats
Use --ssl to enable encrypted communication
ecflow_server --ssl ecflow_client --ssl --stats
Additionally ecFlow_ui will be changed , so that the add server dialog, will now prompt the user to signify a SSL enabled server.
