Using bcrypt-js to Hash Passwords in JavaScript

In this post, we will give you information about Using bcrypt-js to Hash Passwords in JavaScript. Here we will give you detail about Using bcrypt-js to Hash Passwords in JavaScript And how to use it also give you a demo for it if it is necessary.

bcrypt’s hash() function is how to create a secure hash of a password.It takes two parameters: the password and the number of salt rounds. Increasing the number of salt rounds makes bcrypt.hash() slower, which makes your passwords harder to brute force.

const bcryptjs = require('bcryptjs');

const numSaltRounds = 8;

const password = 'password';

bcryptjs.hash(password, numSaltRounds);

We generally recommend a higher numSaltRounds in production (at least 8). However, we often use numSaltRounds = 1 in tests to make tests run faster.

The bcrypt-js library also has a bcryptjs.hashSync(password, numSaltRounds) function. We recomment not using hashSync(), because hashSync() will block your entire Node process while it runs.

compare()

The compare() function is used to essentially decrypt the password. It takes two parameters: the password and the hash.
If the function returns true, then the password passed was the correct password.

const bcryptjs = require('bcryptjs');

const numSaltRounds = process.env.NODE_ENV === 'test' ? 1 : 12;

const password = 'password';

const hash = bcryptjs.hash(password, numSaltRounds);

bcryptjs.compare(password, hash); // true

There is no way to get the original password from the bcrypt hash without guessing the password.

Make sure you use the exact same number of salt rounds when generating the hash using hash(), and when comparing using compare().
If you compare() using a different number of salt rounds than the hash was generated with, compare() will always fail.

 

Node.js is an open-source, cross-platform JavaScript runtime environment. Node.js allows you to run JavaScript code outside of a web browser. This makes it possible to create a wide variety of applications, including web servers, real-time chat applications, and data processing pipelines.

Node.js is built on top of the V8 JavaScript engine, which is also used by Google Chrome. This means that Node.js applications can take advantage of the same performance and features as Chrome.

Node.js is a popular choice for building web servers. This is because Node.js is very efficient at handling concurrent requests. Node.js uses a non-blocking event loop to handle requests, which means that it can handle multiple requests at the same time without slowing down.

Node.js is also a good choice for building real-time chat applications. This is because Node.js is able to push data to clients in real time without the need for polling. This makes it possible to create a smooth and responsive user experience.

Node.js is a powerful tool that can be used to create a wide variety of applications. If you are looking for a JavaScript runtime environment that is fast, scalable, and efficient, then Node.js is a great choice.

Here are some of the benefits of using Node.js:

  • Performance: Node.js is very efficient at handling concurrent requests. This makes it a good choice for building web servers and real-time chat applications.
  • Scalability: Node.js is designed to scale horizontally. This means that you can add more nodes to your cluster to handle more traffic.
  • Efficiency: Node.js uses a non-blocking event loop to handle requests. This makes it possible to handle multiple requests at the same time without slowing down.
  • Community: Node.js has a large and active community. This means that there are many resources available to help you learn and use Node.js.
