Node.js Password Hash Generator
Generate a real bcrypt hash matching what Node.js's bcrypt/bcryptjs packages produce - the most common Node.js password-hashing approach.
This generates a real bcrypt hash in the exact format Node's bcrypt/bcryptjs packages produce and verify with bcrypt.compare().
Computed using a real bcrypt implementation running entirely in your browser - your password is never transmitted anywhere.
No Node.js code is executed - this is a genuine, algorithm-correct bcrypt hash, not a simulated example.
How Node.js Commonly Hashes Passwords
The most widely used approach in Node.js applications is bcrypt, via either the native bcrypt package or the pure-JavaScript bcryptjs package - both produce identical, standard bcrypt hash strings and are interchangeable for verification.
Why Use This Tool?
Useful for seeding a database or test fixture for a Node.js application without writing a one-off script, since the output is directly usable with bcrypt.compare(password, hash).
How to Use It
- Enter a password.
- Set the cost/rounds factor (bcryptjs commonly defaults to 10).
- Copy the generated hash - directly usable with
bcrypt.compareSync(password, hash)or its async equivalent.
Limitations
Node's built-in crypto.scrypt() is another option some applications use instead of bcrypt - since scrypt doesn't have one single self-contained string format, that use case is better served by the dedicated Scrypt Hash Generator, where you can see the raw parameters.
