/*

This module creates an HTTPS web server and serves static content
from a specified directory on a specified port.

To generate a new cert:

  openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 365

To remove the passphrase requirement:

  openssl rsa -in key.pem -out newkey.pem && mv newkey.pem key.pem

Or just include the "passphrase" option when configuring the HTTPS server.
