How this tool works

What it accepts, how to use it, and where your input is processed.

Bcrypt is a password hashing function designed by Niels Provos and David Mazières. It is based on the Blowfish cipher and remains one of the most secure ways to store user credentials today.

How verification works:

Bcrypt includes a 'salt' within the hash itself to protect against rainbow table attacks. Our tool uses the standard bcrypt.compare() algorithm to verify your plain text against the provided hash.

Security Tip: To keep your production systems safe, never share real production hashes on public websites. This tool is designed for development and debugging purposes.
