Intro

This utility creates robust bcrypt hashes for passwords and lets you verify raw text against existing hashes securely in the browser.

How to use

  1. Enter a password
    Type the plain-text password you want to hash.
  2. Select rounds
    Choose the bcrypt cost factor (default 10). Higher rounds = more secure but slower.
  3. Copy the hash
    Copy the generated bcrypt hash for storage in your database or config file.

Examples

Hash Password
Create a bcrypt hash with 10 rounds.
Input
my_secret_password
Output
$2a$10$wTfHq... (Hash string)
Higher cost factor
Generate a bcrypt hash with 12 rounds for stronger security.
Input
mySecurePassword (rounds: 12)
Output
$2b$12$LJ3m4ys3Lz.PQOqYPeUoGuF0f6Y5s/K/VO

FAQ

What is bcrypt?

Bcrypt is a password hashing algorithm designed to be slow and resistant to brute-force attacks. It incorporates a salt automatically and supports an adjustable cost factor.

What are bcrypt rounds?

The rounds (or cost factor) determine how many times the hashing operation is repeated. Each increment doubles the computation time. The default of 10 is suitable for most applications today.

Is bcrypt better than SHA-256 for passwords?

Yes for password storage. Bcrypt is intentionally slow and includes a salt, making it resistant to rainbow table and brute-force attacks. SHA-256 is fast by design, which is a disadvantage for password hashing.
