Once hashing has been done, it should be I am new to ExpressJS. What should we do to protect other user information that does need to be decrypted? There are important differences between hashing and encryption, the one you violate most blatantly being the requirement that encryption retains the information provided in the clear } return hash. Learn how to securely hash and verify passwords in Node. Also Read: Node Crypto Module – Encrypt and Decrypt Data In this tutorial, we’ll go over the basics of cryptography in Node. digest('base64'); // returns hash as string } I use this code ensure generated lines of a file aren't edited by someone manually. js module that provides cryptographic functionality including: Hash functions (SHA-256, SHA-512, etc. js built-in crypto module. Salting a password A salt is a random string. js node I'm trying to encrypt passwords in nodejs for a website using express. By fortifying our authentication mechanisms with secure password hashing using the bcrypt package, we’ve taken significant steps In this tutorial, we don’t use a popular database system or RESTful web API implementation because we’re focusing on bcrypt By the end of this article, you'll have a comprehensive understanding of bcrypt, equipped with the knowledge to securely hash bcryptjs is a JavaScript implementation of the bcrypt password hashing function.
