What is bcrypt?

A bcrypt tool for the salted, slow password hash used by most frameworks. Generate a hash for storage, or check a password against one.

How it works

It uses the audited bcryptjs library entirely in the browser — no network, no server-side processing, and the salt is embedded in the output hash.

Frequently asked questions

What cost factor should I use?

10–12 is typical for 2026-era hardware. Higher is slower and more resistant to brute force; the tool caps at 15 so pages don't freeze.
