๐Ÿ›ก๏ธBcrypt Hash & Verify

Hash passwords with bcrypt and verify them

Higher = more secure but slower. 10โ€“12 is recommended.

About the Bcrypt Hash & Verify

Bcrypt Hash & Verify hashes passwords with the bcrypt algorithm at an adjustable cost, and verifies a password against an existing bcrypt hash.

Bcrypt is a slow, salted hash designed for passwords. All computation happens locally in your browser.

Common use cases

  • Generating bcrypt hashes for seed data or testing
  • Verifying a password matches a stored hash
  • Experimenting with bcrypt cost factors
  • Learning how password hashing works

How to use the Bcrypt Hash & Verify

  1. Choose Hash or Verify mode.
  2. Enter the password (and a hash for verify).
  3. Run it and copy the result.

Frequently asked questions

What is the cost factor?

It controls how slow the hash is โ€” higher values are more resistant to brute force but take longer. 10โ€“12 is recommended.

Why is bcrypt slow on purpose?

Deliberate slowness makes large-scale password cracking far more expensive for attackers.

Is my password uploaded?

No, hashing and verification run entirely in your browser.
