Vue 3: CryptoJS vs Web Crypto API

What are the main differences between CryptoJS and the Web Crypto API in Vue 3?

CryptoJS is a JavaScript library for cryptographic functions, while the Web Crypto API is a built-in browser API that provides a more secure and efficient way to perform cryptographic operations. CryptoJS is easier to use for simple tasks, but the Web Crypto API is recommended for production due to its performance and security.

Which one should I use for a new Vue 3 project?

If security is a priority, I recommend using the Web Crypto API, as it is more secure and optimized for performance. However, if you need quick and simple cryptographic functions, CryptoJS can be a good choice.

Can you give me an example of how to implement both in Vue 3?

Sure! For CryptoJS, you can install it via npm and then import it in your component. For the Web Crypto API, you can use the window.crypto object directly. Would you like a code snippet for both?

Yes, please provide the code snippets!

Here's a simple example for CryptoJS:

import CryptoJS from 'crypto-js';

const encrypted = CryptoJS.AES.encrypt('my message', 'secret key').toString();
const decrypted = CryptoJS.AES.decrypt(encrypted, 'secret key').toString(CryptoJS.enc.Utf8);

And for the Web Crypto API:

const encoder = new TextEncoder();
const data = encoder.encode('my message');
const key = await window.crypto.subtle.generateKey({
  name: 'AES-GCM',
  length: 256
}, true, ['encrypt', 'decrypt']);
const encrypted = await window.crypto.subtle.encrypt({
  name: 'AES-GCM',
  iv: new Uint8Array(12)
}, key, data);
