For example, if the server ip is 192.168.0.101 and the service port is 18331, then the URL to browse is "http://192.168.0.101:18331". For example, if the server ip is 192.168.0.101 and the service port is 18331, then the URL to browse is "http://192.168.0.101:18331".
## Run as https
1. (Optional) Create a self-signed certificate and a private key. Or, obtain a signed certificate and private key.
\# openssl req -x509 -newkey rsa:2048 -nodes -out **cert.pem** -keyout **key.pem** -days 9999
2. To start the screen sharing service with https, run "**python screenshare.py -s [-p port] [-w password] [-c cert.pem -k key.pem]**".
The default service port is 18331. Example commands are below.
\# host screenshots on port 18331 and no password, https with default built-in certificate and private key
python screenshare.py **-s**
\# host screenshots on port 443 and password "abcdef", https with default built-in certificate and private key
python screenshare.py **-s** -p 443 -w abcdef
python screenshare.py **-s** --port 443 --password abcdef
\# host screenshots on port 18331 and no password, https with a certificate file and a private key file
python screenshare.py **-s** -c cert.pem -k key.pem
3. On other computers, open a web browser and browse "**https://serverip:port**".
For example, if the server ip is 192.168.0.101 and the service port is 18331, then the URL to browse is "https://192.168.0.101:18331".
You will see a warning about the self-signed certificate in the web browser. Accept the warning and continue.
