About Bcrypt Hash Generator

What this page solves

Most bcrypt generators online send your plaintext password to a remote server to hash it — which is the one operation you should never trust to a third party. This tool runs `bcryptjs` entirely in your browser, so the plaintext never crosses the network.

Bcrypt Generator hashes any plaintext password with the bcrypt algorithm (cost factor 4–14, default 10) using `bcryptjs` compiled to WebAssembly — entirely in your browser — so the secret you are hashing never leaves your device.

It exists for the developer moment when you need a real bcrypt hash for a fixture, test user, or admin reset and the alternatives are either spinning up Node to run `bcrypt.hash()`, or pasting your real password into a random online form. Pair it with the Password Generator to generate a strong plaintext first, or with the Hash Generator when you need MD5, SHA-1, SHA-256, or SHA-512 instead. Runs entirely in your browser — no upload, no signup, no logs.

Common Use Cases

  • Generate bcrypt hashes for seed users in a Laravel, Rails, or Django fixture
  • Create a `htpasswd` entry to protect an Nginx or Apache directory
  • Reset an admin password directly in the database without running framework code
  • Test login flows that require a specific bcrypt cost factor (4 for tests, 12 for prod)
  • Verify a stored hash matches a known plaintext during incident response
  • Generate Spring Security `BCryptPasswordEncoder`-compatible hashes for Java fixtures

Frequently asked questions

How to use Bcrypt Hash Generator?

1) Open the tool. 2) Enter or upload your input. 3) Get your result instantly. Everything happens locally — nothing is uploaded.

When should I use Bcrypt Hash Generator?

Use it when seeding a development database, writing a Laravel / Rails / Django fixture, generating a `htpasswd` entry, or testing a login flow that expects bcrypt hashes with a specific cost factor.

Is Bcrypt Hash Generator safe?

Yes. Bcrypt Hash Generator runs 100% in your browser. Inputs are never uploaded, stored, or logged — safe for confidential content.

Will quality be affected by Bcrypt Hash Generator?

Bcrypt Hash Generator performs lossless operations — your content is not re-encoded or downgraded.

What formats does Bcrypt Hash Generator support?

Bcrypt Hash Generator supports all common formats — paste, type, or load from a file.

Is Bcrypt Hash Generator free?

Yes — Bcrypt Hash Generator is completely free, with no registration, no watermarks, and no usage limits.

What cost factor should I use?

For production logins use 10–12 (the OWASP 2024 recommendation; ~250–1000 ms per hash on modern hardware). For test fixtures use 4 — it produces a real bcrypt hash but completes in <10 ms so your test suite stays fast. The OWASP guidance moves up roughly every 2 years; re-evaluate annually.

Will the output verify against my framework?

Yes — the hash is a standard `$2a

lt;cost>
lt;salt><hash>` string. Laravel, Rails, Django, Spring Security, and Node `bcrypt` all verify it identically.

Is it really safe to hash a real password here?

Yes — the hash is computed locally by `bcryptjs` running as JavaScript in your tab. The page makes zero network requests after load (verify in DevTools → Network). Nothing is logged. That said: the *better* habit is to generate a strong random plaintext with the [LINK:Password Generator|/tool/password-generator] and only paste that into hashers — never your own real passwords.

Why are the hashes different every time even with the same password?

Bcrypt salts every hash with 16 random bytes by design — that is what makes pre-computed rainbow tables useless. To verify a password against a stored hash, the algorithm extracts the salt from the stored hash and re-hashes with it.
