How can I implement JSON encryption in my application?

You can implement JSON encryption by using libraries like CryptoJS or built-in functions in languages like Python.

Can you show me a simple example using CryptoJS?

Sure! Here's a basic example:

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

// Encrypt
const jsonData = JSON.stringify({ name: 'John', age: 30 });
const secretKey = 'mySecretKey';
const encryptedData = CryptoJS.AES.encrypt(jsonData, secretKey).toString();

// Decrypt
const bytes = CryptoJS.AES.decrypt(encryptedData, secretKey);
const decryptedData = JSON.parse(bytes.toString(CryptoJS.enc.Utf8));
console.log(decryptedData);

What are the security considerations I should keep in mind?

Make sure to use a strong secret key, keep it safe, and consider using a secure key management system.
