Bcrypt is a password-hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher. It incorporates:
- Salt to protect against rainbow table attacks
- Adaptive computation cost to remain resistant to brute-force attacks as hardware improves
- Standard format that includes algorithm, cost factor, salt, and hash
Recommended salt rounds: 10-12 for most applications. Each increment doubles the computation time.
This Bcrypt Hash Generator & Verifier is a free online tool designed to help developers and security professionals generate secure bcrypt password hashes and verify existing hashes against plain text.
Bcrypt is a widely used password hashing algorithm that automatically handles salting and supports configurable cost factors, making it resistant to brute-force and rainbow table attacks.
With this tool, you can:
- Generate bcrypt hashes with adjustable salt rounds
- Verify plain text against existing bcrypt hashes
- Understand bcrypt hash format and security best practices
This tool is ideal for testing, learning, and educational purposes. For production applications, bcrypt hashing should always be implemented on the server side.
