what is crypto JS in angular 8?

CryptoJS is a popular JavaScript library that provides cryptographic algorithms and protocols for secure communication. It is often used in web development to add security features such as password hashing, message authentication, and encryption.

In an Angular 8 project, you can use CryptoJS to add cryptographic functionality to your application. For example, you can use it to hash passwords before storing them in a database, or to encrypt and decrypt data being transmitted between the client and server.

To use CryptoJS in your Angular 8 project, you will need to install it first using npm (the package manager for JavaScript). You can then import the library into your Angular components and services and use its functions as needed.

CryptoJS is a JavaScript library that provides cryptographic algorithms and protocols for secure communication. It can be used in a variety of contexts but is often used in web development to add security features to applications. Some common uses for CryptoJS in Angular 8 projects include:

Hashing passwords: You can use CryptoJS to hash passwords before storing them in a database, to help protect against password-cracking attacks.

Message authentication: You can use CryptoJS to create and verify message authentication codes (MACs), which can be used to ensure the integrity and authenticity of messages being transmitted between the client and server.

Encryption and decryption: You can use CryptoJS to encrypt and decrypt data being transmitted between the client and server, to help protect against eavesdropping attacks.

Other security-related tasks: CryptoJS can also be used for other security-related tasks such as generating random numbers, generating hash-based message authentication codes (HMACs), and more.

Keep in mind that while CryptoJS can be a useful tool for adding security features to your application, it is important to also consider other security measures such as proper server-side validation, input sanitization, and so on.

How to install crypto JS in angular 8?

To install CryptoJS in your Angular 8 project, follow these steps:

1). Open a terminal window and navigate to your Angular 8 project directory.

2). Run the following command to install CryptoJS:

npm install crypto-js

This will install CryptoJS as a dependency in your project.

3). In the Angular component or service where you want to use CryptoJS, import the library by adding the following line at the top of the file:

import * as CryptoJS from 'crypto-js';

4). You can now use the functions provided by CryptoJS in your component or service. For example, to hash a password using CryptoJS, you can use the following code:

const hash = CryptoJS.SHA256("my password");

5). Save your changes and you should now be able to use CryptoJS in your Angular 8 project.

Keep in mind that you will need to repeat these steps for each Angular component or service where you want to use CryptoJS.

To uninstall CryptoJS from your Angular 8 project, follow these steps:

1). Open a terminal window and navigate to your Angular 8 project directory.

2). Run the following command to uninstall CryptoJS:

3).npm uninstall crypto-js

4). If you have imported CryptoJS in any of your project files, you will need to remove the import statements. For example:

import * as CryptoJS from 'crypto-js';

Save your changes and you should now be able to build and run your Angular 8 project without the CryptoJS library.

If you are using CryptoJS in your project and want to switch to a different library, you can follow a similar process to uninstall CryptoJS and install the new library using npm.

Crypto browserify angular Example:

Browserify is a tool that allows you to use Node.js-style require() statements to import modules in the browser. Angular is a JavaScript framework for building web applications.

Here is an example of how you can use Browserify with Angular to import the CryptoJS library, which provides cryptographic functionality, into your Angular application:

1). Install the required libraries:

npm install --save crypto-js browserify angular

2). Use Browserify to build a bundle containing the CryptoJS library:

browserify -r crypto-js > static/crypto.js

3).<script src="/static/crypto.js"></script>

4).const CryptoJS = require('crypto-js');

const encrypted = CryptoJS.AES.encrypt('my message', 'secret key 123');

console.log(encrypted.toString());

const decrypted = CryptoJS.AES.decrypt(encrypted, 'secret key 123');

console.log(decrypted.toString(CryptoJS.enc.Utf8));

This is just a basic example, but it should give you an idea of how to use Browserify with Angular to include the CryptoJS library in your application.
