Description

Hey, i was searching a good way to store passwords/private data in a database using hashing, would this be a secure way?

const crypto = require('crypto');
const randomSalt = crypto.randomBytes(64).toString('hex'); //generate an unique salt for every password

const data = "hello world"
const saltedData = data + randomSalt;

const hash = crypto.createHash('sha3-512');
hash.update(saltedData);
const hashedData = hash.digest('hex');

//then store hashedData in a database

Minimal Reproduction

1. Run the code above

if you use a hash function based on random value, it may be too secure to be able to decrypt it! how you plan to retrieve the password later?

the usual practice IMO is to use:

• asymmetric encryption for data that moves across n/w
• symmetric ones for data at rest (storing in your own device)
• hash functions if you only want to store a mirror of the data (no un-hashing possible)

caveat: I am not an expert in this area.
