Bcrypt Hash Generator & Verifier

Generate secure bcrypt password hashes and verify passwords against hashes

Note: Bcrypt is a one-way hashing algorithm. You cannot "decrypt" a bcrypt hash back to the original password. You can only verify if a password matches a hash.

About Bcrypt

Bcrypt is a password hashing function designed to be slow and computationally expensive, making it resistant to brute-force attacks. It's widely used for securely storing passwords.

Key Features

  • One-way hashing: Cannot be reversed or decrypted
  • Salted: Automatically includes a random salt
  • Adjustable cost: Can be made slower as computers get faster
  • Industry standard: Used by major applications worldwide

Hash Format

A bcrypt hash looks like this:

$2a$10$N9qo8uLOickgx2ZMRZoMyeIjZAgcfl7p92ldGxad68LJZdL17lhWy

Format: $2a$[cost]$[22 character salt][31 character hash]

Privacy & Security

All hashing and verification happens locally in your browser. Your passwords never leave your device and are not sent to any server.
