Higher cost = slower but more secure. Each hash uses a unique salt, so hashing the same password twice yields different output — that is expected.

About Bcrypt Hash Generator

The Bcrypt Generator hashes a password with bcrypt, the slow, salted algorithm designed specifically for secure password storage. You control the cost factor (salt rounds), which sets how much work an attacker must do per guess. Hashing runs entirely in your browser, so the password never leaves your device. To check a password against an existing hash, use the Bcrypt Compare tool.

How to Use

1Open Bcrypt Hash Generator and paste or type your data into the input area.
2Adjust any available options to match the result you want.
3Your output is generated instantly — no button-clicking required for most tools.
4Use the Copy or Download button to save your result.

Common Use Cases

Generating checksums to verify file and data integrity
Creating unique identifiers for records and keys
Hashing passwords and secrets during development
Comparing hashes to detect tampering or duplicates

Frequently Asked Questions

What are bcrypt salt rounds?

The salt rounds, or cost factor, control how many iterations bcrypt performs. Higher rounds make each hash slower to compute, which slows brute-force attacks. A cost of 10-12 is a common, sensible default.

Why use bcrypt instead of SHA256 for passwords?

Fast hashes like SHA-256 let attackers try billions of guesses per second. Bcrypt is deliberately slow and salted, so it resists brute-force and rainbow-table attacks, making it the right choice for passwords.

Is Bcrypt Hash Generator free to use?

Yes. Bcrypt Hash Generator is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use Bcrypt Hash Generator?

Absolutely. Bcrypt Hash Generator runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
