Bcrypt Hash Generator Online — Bcrypt password hashing tool — Free Online Tool

Bcrypt is the industry standard for password hashing. Its adaptive cost factor means you can make it slower as hardware gets faster, keeping brute-force attacks expensive.

By DevKits Team

What is Bcrypt?

Bcrypt is a password-hashing function designed by Niels Provos and David Mazières. Unlike SHA-256, Bcrypt is intentionally slow and includes a salt automatically, making rainbow table and brute-force attacks computationally expensive. The cost factor (rounds) lets you tune difficulty over time.

DevKits provides a free browser-based bcrypt hash generator online that processes everything client-side — your data never leaves your machine. No signup, no install, no rate limits.

How to Use the Bcrypt Hash Generator Online

  1. 1. Enter the plain-text password in the input field.
    2. Set the cost factor (10–14 recommended for production).
    3. Click Hash Password to generate the $2b$ prefixed hash.

Key Features

  • Adjustable cost factor slider
  • auto-generated salt
  • verify mode (check plain-text against stored hash)
  • 100% browser-based — no server processing, complete privacy
  • No account required — free forever
  • Works on desktop and mobile
