This main purpose is to create self signed ssl certificates with mkcert@Subash and write a quick demo locally with Node.js.
Step 1: Install NPM package mkcert
$npm install mkcert
Step 2: Create ca.key and ca.crt
$node_modules/mkcert/src/cli.js create-ca
It generates two files
ca.key,ca.crtinnode_modules/mkcert/src.
Step 3: Create cert.key and cert.crt
$node_modules/mkcert/src/cli.js create-cert
It generates two files
cert.key,cert.crtinnode_modules/mkcert/src.
Step 4: For the convenience, copy ca and cert out.
$cp node_modules/mkcert/src/ca.key ./ca.key
$cp node_modules/mkcert/src/ca.cert ./ca.crt
$cp node_modules/mkcert/src/cert.key ./cert.key
$cp node_modules/mkcert/src/cert.crt ./cert.crt
The directory looks like this.
./node_modules
./client.js
./server.js
./ca.key
./ca.crt
./cert.key
./cert.crt
Step 5: Write codes on server side
in server.js
const https = require('https');
const fs = require('fs');
const hostname = '127.0.0.1';
const port = 3001;
const server = https.createServer({
key: fs.readFileSync("./cert.key"),
cert: fs.readFileSync("./cert.crt"),
}, (req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello World\n');
});
server.listen(port, hostname, () => {
console.log(`Server running at https://${hostname}:${port}/`);
});
Step 6: Write codes on client side
in client.js
const https = require('https');
const fs = require('fs');
const options = {
hostname: 'localhost',
port: 3001,
method: 'GET',
ca: fs.readFileSync('./ca.crt'),
};
const req = https.request(options, (res) => {
res.on('data', (d) => {
process.stdout.write(d);
});
}).on('error', (e) => {
console.error(e);
});
req.end();
Step 7: Start a server
$node server.js
Step 8: Send a request to server
$node client.js
You can send a request with
curl. Remember to put--cacert
$curl --cacert ./ca.crt -X GET https://localhost:3001
Thank you!
