Bcrypt Hash Generator & Verifier

Securely generate bcrypt hashes for passwords with custom salt rounds, and verify if a string matches an existing hash. It runs entirely in your browser — no data is sent to any server, no account required, and it's completely free.

Generate Hash

Higher rounds take exponentially longer to compute. 10 or 12 is recommended for modern web apps.

How to Use the Bcrypt Hash Generator & Verifier

  1. 1

    Generate a Hash

    Enter a plain text string (like a password) and adjust the salt rounds. Click Generate.

  2. 2

    Check a Match

    Paste an existing Bcrypt hash and a plain text string into the Verifier.

  3. 3

    Verify

    Click Check Match to securely verify if the string matches the hash.

Frequently Asked Questions

What is Bcrypt?

Bcrypt is a password-hashing function designed to be computationally expensive to resist brute-force search attacks.

What are salt rounds (cost factor)?

The cost factor determines how many iterations the algorithm runs. Each increment doubles the computing time. 10 or 12 is standard.

Is my data secure?

Yes! The hashing and verification are performed securely in your browser using JavaScript. No passwords or hashes are ever sent to a server.
