How can I store encrypted data in Vue 3?

How can I store encrypted data in Vue 3?

You can use libraries like CryptoJS to encrypt data before storing it in local storage or Vuex.

Can you show me a code example?

Sure! Here's a simple example:

import CryptoJS from 'crypto-js';

const secretKey = 'mySecretKey';

// Encrypting data
const data = 'sensitive data';
const encryptedData = CryptoJS.AES.encrypt(data, secretKey).toString();

// Storing in local storage
localStorage.setItem('encryptedData', encryptedData);

// Decrypting data
const storedData = localStorage.getItem('encryptedData');
const bytes = CryptoJS.AES.decrypt(storedData, secretKey);
const originalData = bytes.toString(CryptoJS.enc.Utf8);

This will securely store and retrieve your data.

What if I want to use Vuex instead of local storage?

You can store the encrypted data in Vuex state just like you would with local storage. Just ensure to encrypt it before committing to the state.

Are there any security concerns I should be aware of?

Yes, always ensure your secret key is kept safe and consider using environment variables to manage sensitive information.
