How can I implement data encryption in a MEAN stack application?

You can implement data encryption in a MEAN stack application by using libraries like CryptoJS for client-side encryption and Mongoose for server-side data handling.

What types of data should I encrypt?

You should encrypt sensitive data such as user passwords, personal information, and any financial data to protect user privacy.

Can you show me a code example for encrypting passwords?

Sure! You can use bcrypt for password hashing. Here's a simple example:

const bcrypt = require('bcrypt');
const saltRounds = 10;

bcrypt.hash('myPassword', saltRounds, function(err, hash) {
  // Store hash in your password DB.
});

How do I decrypt the data when I need to access it?

For passwords, you don't decrypt them; instead, you compare the hashed version with the input. For other data, you can use the same library to decrypt it.
