This is a simple demo of how to use ACME to get a certificate and use it for HTTPS:
> node ca.js & # Start up the CA
> node server.js # Get a cert and start an HTTPS server
Starting the server up will take a few seconds, to do two JS crypto operations:
- The server generating a 2048-bit RSA key pair
- The CA computing a 4096-bit RSA signature
The HTTPS server gets a cert for example.com and runs on port 8090. So if you have example.com mapped to ::1 in your /etc/hosts file, you should now be able to access https://example.com:8090.
