What cost factor should I use?

Use the highest that stays under ~500ms on your server. Cost 12 is a common start.

Is bcrypt better than SHA-256 for passwords?

Yes, because bcrypt is intentionally slow and includes a salt.

Can I decrypt a bcrypt hash?

No. It's one-way; you only verify by comparing hashes.

Demo Only: This is a simplified bcrypt simulation. For production use, implement bcrypt server-side using a proper library like bcryptjs or bcrypt.

Hashing happens entirely in your browser. Your password is never transmitted anywhere.

What is bcrypt?

A slow password hashing function designed to resist brute-force.

Cost factor

Higher cost = slower hashing = harder to attack.

Important

In real apps, hash passwords on the server (not client-side).
