Bcrypt Generator
FreeHash passwords with bcrypt and verify hash matches
About Bcrypt Generator
Storing passwords as plain text or fast hashes like MD5 is a serious liability, and bcrypt remains a trusted answer because it is deliberately slow and salts every hash automatically. This Bcrypt Generator lets you produce a bcrypt hash from any input and verify whether a given password matches an existing hash, so you can test your authentication logic without writing a throwaway script.
Enter a password, pick a cost factor, and the tool returns a salted bcrypt hash you can drop into seed data or a test fixture. Switch to verify mode to confirm a password and hash pair line up. Everything runs free in your browser with no account required, which keeps your test credentials out of third-party logs while you debug login flows or migrate a user table.
Common uses
- Generating a bcrypt hash to seed a test or demo user account
- Verifying that a stored hash matches an expected password during debugging
- Comparing how different cost factors change hash output and time
- Creating fixtures for automated authentication tests
- Confirming your backend produces compatible bcrypt hashes

FAQ
Why does the same password produce different hashes each time?
Bcrypt embeds a random salt in every hash, so two runs on the same password give different output. That is by design and is why you verify with a match check rather than comparing strings.
What cost factor should I use?
Higher cost means slower hashing and stronger resistance to brute force. A value around 10 to 12 is a common production starting point; tune it to your hardware and latency budget.
Should I hash real production passwords here?
Use it for testing and learning. For live systems, hash passwords inside your own application so credentials never leave your infrastructure.
Can I use Bcrypt Generator on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
