Intro to crypto module

Crypto module and SHA256 hashing

Report a typo

Hey there! This problem might be a bit unpredictable, but give it a go and let us know how you do!

Given the following code snippet, determine which statement is correct regarding the use of the 'crypto' module in Node.js.

const crypto = require('crypto');
const secret = 'abcdefg';
const hash = crypto.createHmac('sha256', secret)
                   .update('I love cupcakes')
                   .digest('hex');
console.log(hash);

Select one option from the list

This code will output 'I love cupcakes'.

The 'crypto' module is being used incorrectly; it doesn't support cryptographic functionality.

This piece of code initializes a new HTTP server.

This code synchronously creates a hash using the SHA256 algorithm with a secret key and then logs the result.

The update method in the 'crypto' module is used to add a pathname to the synced file.
