How do I implement bcrypt in Node.js?

To implement bcrypt in Node.js, you first need to install the bcrypt package using npm. You can do this by running npm install bcrypt.

What are the basic functions I need to use?

The main functions you'll use are bcrypt.hash() for hashing passwords and bcrypt.compare() for verifying them.

Can you show me a code example?

Sure! Here's a simple example:

const bcrypt = require('bcrypt');

const password = 'myPassword';
const saltRounds = 10;

// Hashing the password
bcrypt.hash(password, saltRounds, function(err, hash) {
    // Store hash in your password database
});

// Verifying the password
bcrypt.compare(password, hash, function(err, result) {
    // result == true if the password matches
});

How secure is bcrypt compared to other hashing algorithms?

Bcrypt is considered very secure because it incorporates a salt to protect against rainbow table attacks and allows you to adjust the cost factor, making it slower and more resistant to brute-force attacks.
