import { HomeComponent } from './components/home/home.component';
import { UserComponent } from './components/user/user.component';
import { UserService } from './components/service/user.service';

React | Encryption and Decryption Data/Text using CryptoJs

To encrypt and decrypt data, simply use encrypt () and decrypt () function from an instance of crypto-js. Node.js (Install) Requirements: 1. Node.js 2. npm (Node.js package manager) 3. npm install crypto-js npm install crypto - js Usage - Step 1 - Import var CryptoJS = require ( "crypto-js" ); Step 2 - Encrypt // Encrypt var ciphertext = CryptoJS . AES . encrypt ( JSON . stringify ( data ), 'my-secret-key@123' ). toString (); Step 3 -Decrypt // Decrypt var bytes = CryptoJS . AES . decrypt ( ciphertext , 'my-secret-key@123' ); var decryptedData = JSON . parse ( bytes . toString ( CryptoJS . enc . Utf8 )); As an Example, import React from 'react' ; import './App.css' ; //Including all libraries, for access to extra methods. var CryptoJS = require ( "crypto-js" ); function App () { var data

Angular 7 and 8 Validate Two Dates - Start Date & End Date

In this example, I am sharing “ How to compare or validate two dates in Angular? ” using custom validation function in Angular 7 and Angular 8 . Here, I’m validating the two dates - a start date and end date. The end date should be greater than the Start date”. Let’s see the example :- import { Component , OnInit } from '@angular/core' ; import { UserRequest } from '../model/user' ; @ Component ({ selector: 'User_Cal' , templateUrl: './usercal.component.html' , styleUrls: [ './usercal.component.css' ] }) export class UserCalComponent implements OnInit { constructor ( private EncrDecr : EncrDecrService , private http : HttpClient , private datePipe : DatePipe ) { } //model class model = new UserRequest ( null , null , null , null , null ); //Error Display error : any ={ isError: false , errorMessage: '' }; isValid

Encryption and Decryption Data/Password in Angular

You can use crypto.js to encrypt data. We have used 'crypto-js'. Follow the below steps, Steps 1 – Install CryptoJS using below NPM commands in your project directory npm install crypto-js --save npm install @types/crypto-js –save After installing both above commands it looks like – NPM Command 1 -> npm install crypto-js --save NPM Command 2 -> npm install @types/crypto-js --save Steps 2 - Add the script path in “ angular.json ” file. "scripts" : [ "../node_modules/crypto-js/crypto-js.js" ] Steps 3 – Create a service class “ EncrDecrService ” for encrypts and decrypts get/set methods . Import “ CryptoJS ” in the service for using encrypt and decrypt get/set methods . import { Injectable } from '@angular/core' ; import * as CryptoJS from 'crypto-js' ; @ Injectable ({ providedIn: 'root' }) export class EncrDecrS
