How do I implement Bcrypt for password hashing?

How do I implement Bcrypt for password hashing in my Node.js application?

To implement Bcrypt in your Node.js app, first install the Bcrypt package using npm: npm install bcrypt. Then, you can use it to hash passwords.

Can you show me a code example for hashing a password?

Sure! Here's a simple example:

const bcrypt = require('bcrypt');

const saltRounds = 10;
const myPlaintextPassword = 'password123';

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

How do I compare a plain password with the hashed one?

You can use bcrypt.compare() to compare a plain password with a hashed password. Here's how:

bcrypt.compare(myPlaintextPassword, hash, function(err, result) {
  // result == true if the passwords match
});
