BCrypt Generator

How to use BCrypt Generator

1. Open BCrypt Generator — it runs entirely in your browser with no setup.
2. Paste or type your input into the text area, or upload a file where supported.
3. Set any options you need. The result appears in the output panel — there is no upload step and no waiting on a server.
4. Review the output instantly; large inputs are handled locally without lag.
5. Copy the result to your clipboard or download it. Your data never leaves the page.

Why use BCrypt Generator?

• 100% free with no limits, no sign-up and no watermarks.
• Private by design — your data are processed in your browser and never uploaded to a server.
• Fast and lightweight, with instant results even on a phone or a slow connection.
• Works everywhere — any modern browser on Windows, macOS, Linux, Android or iOS.
• Part of a full developer tools suite, so related bcrypt tasks are one click away.

What people use BCrypt Generator for

• Generating a password hash for a seed script or a test fixture.
• Checking whether a candidate password matches an existing bcrypt hash.
• Creating a hashed credential for a config file or a basic-auth setup.

BCrypt Generator: limits and things worth knowing

• bcrypt is deliberately slow, which is the entire point: it is designed to be expensive to brute-force. General-purpose hashes like MD5 and SHA-256 are fast and therefore unsuitable for passwords.
• The salt is generated automatically and stored inside the resulting hash string, which is why the same password produces a different hash each time and why you never need a separate salt column.
• The cost factor is the number after the algorithm identifier and is a power of two. Raising it by one doubles the work; 12 is a common current choice.
• bcrypt silently truncates input after 72 bytes. Long passphrases are cut, and pre-hashing to work around it introduces its own problems.
• Everything runs in your browser, so no password or hash is transmitted.

Is it private and secure?

Your privacy is built in. BCrypt Generator runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
