Bcrypt Hash Generator

Generate and verify bcrypt password hashes with adjustable cost factor (4–14). Free online — runs locally, no upload.

Generate Bcrypt Hash

10

Higher cost = more secure but slower. Default is 10 (≈100ms). 12 takes ~1s, 14 takes ~10s.

Verify Password Against Hash

Bcrypt is the recommended algorithm for password storage. The salt is embedded in the hash itself (the $2a$10$ prefix encodes the version and cost factor), so you don't need to store it separately.

About Bcrypt Hash Generator

Generate and verify bcrypt password hashes online with an adjustable cost factor. Use this when prototyping auth or checking a hash against a candidate password — locally, so credentials are not sent to a remote hasher. Higher cost means slower hashes and stronger brute-force resistance; pick a value your app can afford at login time.

What stays local: Passwords and bcrypt hashes you generate or check.

What you can do with Bcrypt Hash Generator

  • Generate bcrypt hashes
  • Verify password ↔ hash matches
  • Adjustable cost factor (4–14)
  • Fully local browser crypto

How to use Bcrypt Hash Generator

  1. Enter a password. Type the password to hash or verify (stays local).
  2. Set cost. Choose a cost factor your application can afford.
  3. Hash or check. Generate a hash, or paste an existing hash to verify a match.

FAQ — Bcrypt Hash Generator

Privacy, offline use, and how this free online tool works.

What does the bcrypt cost factor control?

Cost (4–14 here) sets how expensive hashing is. Higher cost means slower hashes and stronger resistance to brute-force — pick a value your app can afford at login time.

Are passwords uploaded?

No. Hashing and verification run in your browser only.

Is this a replacement for production password storage guidance?

It is a local helper. Follow your framework’s password hashing best practices for production systems.
