Once you have node.js installed on your system, just follow the procedure below to get a basic web server running with support for both HTTP and HTTPS!

Step 1 : Build a Certificate Authority

  1. create the folder where you want to store your key & certificate :

    mkdir conf


  1. go to that directory :

    cd conf


  1. grab this ca.cnf file to use as a configuration shortcut :

    wget https://raw.githubusercontent.com/anders94/https-authorized-clients/master/keys/ca.cnf


  1. create a new certificate authority using this configuration :

    openssl req -new -x509 -days 9999 -config ca.cnf -keyout ca-key.pem -out ca-cert.pem


  1. now that we have our certificate authority in ca-key.pem and ca-cert.pem, let's generate a private key for the server :

    openssl genrsa -out key.pem 4096


  1. grab this server.cnf file to use as a configuration shortcut :

    wget https://raw.githubusercontent.com/anders94/https-authorized-clients/master/keys/server.cnf


  1. generate the certificate signing request using this configuration :

    openssl req -new -config server.cnf -key key.pem -out csr.pem


  1. sign the request :

    openssl x509 -req -extfile server.cnf -days 999 -passin "pass:password" -in csr.pem -CA ca-cert.pem -CAkey ca-key.pem -CAcreateserial -out cert.pem


Step 2 : Install your certificate as a root certificate

  1. copy your certificate to your root certificates' folder :

    sudo cp ca-crt.pem /usr/local/share/ca-certificates/ca-crt.pem


  1. update CA store :

    sudo update-ca-certificates
