How to use CryptoJS with Angular 2 and TypeScript in WebPack build environment?

There are a whole bunch of questions around using the CryptoJS library with Angular 2 but most assume use of SystemJS and all seem out of date with the current version of TypeScript. Can anybody give clear, simple instructions on how to use the CryptoJS library with Angular 2 and TypeScript.

I've installed CryptoJS using npm install crypto-js.

I've tried the recommended typings install crypto.js --ambient --save but this simply gives a warning about --ambient being deprecated and to use --global instead.

I've used --global instead but that then gives an error saying no typings were available!

Any advice to someone new to WebPack, NodeJS AND TypeScript would be appreciated. I have the CryptoJS library installed under node_modules folder but any "sensible" attempts to "import" CryptoJS fail with "Module not found". enter image description here

Here is the simplest step-by-step install and using example (working in nativescript/typescript/angular project):

npm install crypto-js

then:

npm install --save @types/crypto-js

Import in some component:

import * as crypto from "crypto-js";

And use it:

crypto.DES.decrypt("Your secret", "YOUR_CRYPTO_KEY");

The crypto-js package in npm has no built-in types and no longer maintained.

You can try this, Witch is maintained by me, the same as crypto-js with TypeScript support and ES6 module: https://www.npmjs.com/package/crypto-es.
