Скачать или смотреть Node.js Crypto Trick No One Told You 😳 | Stop Storing Plain Passwords

Learn how login verification works in Node.js — we hash the input password with SHA-256 and compare it with the stored hash from the database.

✅ What you'll learn:

How password verification via hashing works in Node.js
How to create a SHA-256 hash using crypto
Why comparing hashes is used for login

Quick security tips: use salt and stronger password hashing (bcrypt/argon2) and timing-safe comparison

⚠️ Important security note:
SHA-256 is a cryptographic hash but NOT ideal alone for storing passwords. Use bcrypt/argon2 with salts for production. Also compare hashes using timing-safe methods to avoid timing attacks.
