Cifre la cadena en Typecript y descifre en C # utilizando el algoritmo estándar de cifrado avanzado (AES)

Solución:

Tuve un problema similar. Estoy usando Angular 4 / Angular-Cli 1.0.0. Lo que funcionó para mí:

npm install crypto-js --save
npm install @types/crypto-js --save

Después de estos dos comandos, consulte el crypto-js biblioteca en el angular-cli.json archivo, en la matriz “scripts”. En mi caso:

"scripts": [
    "../node_modules/crypto-js/crypto-js.js"
  ]

Notarás que en el node_modules / @ tipos directorio, tendrá un subdirectorio crypto-js. Así que pon una referencia al node_modules/@types/crypto-js/index.d.ts en su código, usando una directiva de triple barra, para que el compilador sepa que el archivo de mecanografía es necesario para compilar ese archivo de módulo:

/// <reference path="relative_path_to_cypto_folder/index.d.ts" />

Alternativamente, también puede usar el atributo “tipos” en lugar de “ruta”, ya que está haciendo referencia a una definición de tipificación dentro de node_modules / @ types:

/// <reference types="crypto-js" />

Después de eso, puede usar su código exactamente como está:

/// <reference types="crypto-js" />

import * as CryptoJS from 'crypto-js';


var key = CryptoJS.enc.Utf8.parse('7061737323313233');
var iv = CryptoJS.enc.Utf8.parse('7061737323313233');
var encrypted = CryptoJS.AES.encrypt(CryptoJS.enc.Utf8.parse("It works"), key,
    {
        keySize: 128 / 8,
        iv: iv,
        mode: CryptoJS.mode.CBC,
        padding: CryptoJS.pad.Pkcs7
    });

var decrypted = CryptoJS.AES.decrypt(encrypted, key, {
    keySize: 128 / 8,
    iv: iv,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.Pkcs7
