About Bcrypt

Bcrypt is a password hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher. It incorporates a salt to protect against rainbow table attacks and adaptive cost to defend against future improvements in computing power.

Key Features:

  • Salt: Automatically generates and incorporates a random salt
  • Cost Factor: Adjustable work factor allows increasing computational cost
  • Slow: Intentionally CPU-intensive to make brute-force attacks impractical

Hash Format:

A bcrypt hash string has the format: $2b$[cost]$[22-char salt][31-char hash]

Security Note: This tool performs client-side hashing using JavaScript, suitable for educational purposes. In production, password hashing should be done server-side.
