Command used to generate the self-signed certificate: cd to proxy/ and

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout nginx-selfsigned.key -out nginx-selfsigned.crt

Once you have the certificate, just run ./build_and_run.sh.

To export the certificate to .pfx, just run:

openssl pkcs12 -export -out nginx-selfsigned.pfx -inkey nginx-selfsigned.key -in nginx-selfsigned.crt
