Generate root SSL certificate

This root certificate can then be used to sign any number of certificates you might generate for individual domains

• Generate key file

openssl genrsa -des3 -out rootCA.key 2048

• Generate certificate file

openssl req -x509 -new -nodes -key rootCA.key -sha256 -days 1024 -out rootCA.pem

This certificate will have a validity of 1,024 days

Trust SSL certificate

You need to to tell your Mac to trust your root certificate so all individual certificates issued by it are also trusted

• Double click “rootCA.pem” file to import it to Keychain Access
• Open Keychain, double click certificate you have just imported, change “When using this certificate” to “Always Trust”

Issue a domain SSL certificate for “localhost”

• Create a new OpenSSL configuration file “server.csr.cnf" so you can import these settings when creating a certificate instead of entering them on the command line

[req]
default_bits = 2048
prompt = no
default_md = sha256
distinguished_name = dn

[dn]
C=RD
ST=random
L=random
O=random
OU=random
emailAddress=random@random.com
CN = localhost

• Create a "v3.ext" file in order to create a X509 v3 certificate

authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names

[alt_names]
DNS.1 = localhost

• Create certificate key

openssl req -new -sha256 -nodes -out server.csr -newkey rsa:2048 -keyout server.key -config <( cat server.csr.cnf )

openssl x509 -req -in server.csr -CA rootCA.pem -CAkey rootCA.key -CAcreateserial -out server.crt -days 500 -sha256 -extfile v3.ext

Use your new SSL certificate

Move server.key and server.crt to an accessible location on your server and include them when starting it.

In an Express app running on Node.js, you’d do something like this:

const path = require("path");
const fs = require("fs");
const https = require("https");
const express = require("express");
const bodyParser = require("body-parser");
const app = express();
const port = 3000;

//////////////////
// Setup server
app.use(bodyParser.json());
app.use(
  bodyParser.urlencoded({
    extended: true,
  })
);

const certOptions = {
  key: fs.readFileSync(path.resolve("./server.key")),
  cert: fs.readFileSync(path.resolve("./server.crt")),
};
const server = https.createServer(certOptions, app);

// Listen request
app.get("/", (request, response) => {
  response.json({ info: "Node.js, Express, and Postgres API" });
});

server.listen(port, () => {
  console.log(`App running on port ${port}.`);
});
