How it works

Two steps, no account

1

Enter a password

Type the password you want to hash — usually for testing, seeding a database, or checking how Bcrypt output looks.

2

Generate and copy

The hash includes the algorithm identifier, cost, and salt all in one 60-character string — the standard Bcrypt format most auth libraries expect.

FAQ

Common questions

Why does this need a server round-trip, unlike the password generator?
This tool uses PHP's built-in password_hash() function so the hash is byte-for-byte what your own PHP backend would produce — matching your server's Bcrypt implementation exactly, rather than a separate JavaScript reimplementation that might drift from it.
Is the password I enter stored anywhere?
No — it's used once to compute the hash for this response and then discarded. It isn't written to a database or file.
Why is the salt "auto-generated" instead of something I choose?
Bcrypt generates a fresh random salt on every call by design, which is why hashing the same password twice produces two different-looking hashes that both still validate correctly — that's the algorithm working as intended, not a bug.
Should I use this hash directly in production?
Only if you understand what you're doing — this is meant for testing, learning, and one-off lookups. Real applications should call password_hash() (or your language's equivalent) directly in application code, not paste hashes generated on a public website into a live user database.

Understanding Bcrypt

What is Bcrypt?

Bcrypt is a password-hashing function designed by Niels Provos and David Mazières. It's based on the Blowfish cipher and includes a salt to protect against rainbow table attacks.

Key Benefits

  1. Slow by Design: Prevents brute-force attacks
  2. Built-in Salt: Protects against rainbow tables
  3. Future-Proof: Adjustable work factor
  4. Industry Standard: Widely trusted and tested

Best Practices

  • Use a cost factor that makes hashing take about 250ms
  • Store the complete hash string including algorithm identifier
  • Never truncate the hash output
  • Use strong, unique passwords as input
  • Regularly review and update cost factors

Hash Format

$2y$10$LQv3c1yqBWVHxkd0LHAkCOYz6TtxMQJqhN8/LcdYaA9Dw.hPki2.q │ │ │ └─────────────────── Hash │ │ └─────────────────── Cost (10) │ └─────────────────── Algorithm Version (2y) └─────────────────── Algorithm Identifier ($2y$)

Remember: Bcrypt is designed to be slow to compute, making it resistant to brute-force attacks. Always use secure methods to store and verify password hashes.
