Bcrypt Generator

Hash passwords using the bcrypt algorithm. Choose cost factor (rounds). Verify bcrypt hashes against plain text. Uses bcryptjs — all in-browser.

📦 Install required package:

npm install bcryptjs

Then replace this component with the implementation below.

Implementation (after installing bcryptjs):

import bcrypt from 'bcryptjs';
// Hash:
const hash = await bcrypt.hash(password, costFactor);
// Verify:
const match = await bcrypt.compare(plain, hash);

Frequently Asked Questions

What cost factor should I use?▼

Cost 10-12 is standard for most apps. Higher cost is more secure but slower.

Can I verify an existing bcrypt hash?▼

Yes. Enter the plain text and hash to verify if they match.
