HTTPS. Remote communication between the Web browser front end and the back end is not

encrypted by default, which means that information such as the user's SSH password is transmitted

in elear text that is readable to anyone. For communication from a remote Client to be encrypted,

the back end must have a certificate, and the front end must communicate with the back end using

HTTPS rather than HTTP. Enabling HTTPS is accomplished most easily through issuing a selfsigned

certificate. Once the certificate is issued, you must make surę that it is used. You can dothis

by starting ndb_setup. py from the command linę with the --use-https [2389] and —certfile [2387] options.
