Bcrypt Generator – Hash & Verify Passwords Online

Bcrypt generator – Free Online Tool

Our free Bcrypt Generator creates secure bcrypt password hashes and lets you check a password against an existing hash. It is a handy helper for developers working with PHP, Laravel, WordPress, Node.js and other frameworks.

What is Bcrypt generator?

Bcrypt is a password hashing algorithm designed in 1999 specifically for storing passwords safely. Unlike fast hashes such as MD5 or SHA-256, bcrypt is deliberately slow and adds a random salt, which makes brute-force and rainbow-table attacks extremely expensive.

A bcrypt hash looks like $2y$10$.... The number after the version is the cost factor: each increase doubles the time needed to compute the hash.

How to use the Bcrypt generator

1. Enter the password or text to hash.
2. Choose a cost factor (10–12 is common).
3. Click generate to create the bcrypt hash.
4. To verify, enter a password and an existing hash to see if they match.

Key features

• Adjustable cost (work factor)
• Automatic random salt
• Password verification against existing hashes
• Compatible with PHP password_hash and most libraries

Common use cases

• Creating test users and seed data for applications
• Resetting an admin password directly in a database
• Checking that stored hashes match expected passwords
• Learning secure password storage

Frequently asked questions

Why does the same password give different hashes?

Each hash uses a new random salt. Verification still works because the salt is stored inside the hash.

What cost factor should I use?

A cost of 10 to 12 balances security and speed for most web applications.

Is bcrypt better than SHA-256 for passwords?

Yes. Bcrypt is slow and salted by design, which is exactly what password storage needs.
