This snippet is about cross-platform AES-GCM-256 encryption & decryption, Where payload is being encrypted using JAVA and decrypted using NODE

sample config :

{
    "masterKey": "sfcpnnjFG6dULJfo1BEGqczpfN0SmwZ6bgKO5FcDRfI=",
    "iterations": 2333,
    "keyLength": 32,

"digest": "sha512"

Node.js Deployment

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

I will be using the root user, but would suggest creating a new user

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

	## VHost for www.example.com without ssl, without proxy, without redirect
	server {
	listen 80;
	server_name www.example.com;

	location / {
	root html/example.com;
	index index.html index.htm;
	try_files $uri $uri/ /index.html;
	}

	;= rem Call DOSKEY and use this file as the macrofile
	;= %SystemRoot%\system32\doskey /listsize=1000 /macrofile=%0%
	;= rem In batch mode, jump to the end of the file

	1 . cd c:/program files/docker/docker
	.\dockercli -Version
	TO check the CLI vrsion
	2. docker image ls - List out the images from docker host
	3. docker container ls - list out the active container
	4. docker system info
	5. docker-compose --version
	6. docker-machine --version
	7. notary --version
	8. docker container run -it ubuntu:latest /bin/bash

	module.exports = ({ name, price1, price2, receiptId }) => {
	const today = new Date();
