const jks = require('jks-js');

const keystore = jks.toPem(fs.readFileSync('/path/to/cert1.jks'), 'password'); 
const { cert, key } = keystore['cert1'];

// Create http client
const httpsAgent = new https.Agent({
  rejectUnauthorized: false, // (NOTE: this will disable client verification)
  cert: cert,
  key: key,
  // passphrase: "YYY" // optional
})
const instance = axios.create({ httpsAgent })

// Create server
const server = new https.createServer({ cert: cert, key: key }); 
const wss = new WebSocket.Server({ server });
