BCrypt Hash Generator

Generate secure BCrypt hashes for password storage with customizable cost factor

Password strength:
BCrypt Options:
Higher = More secure but slower (4-15). Default: 10
Recommended: Cost factor of 10-12 for web applications. Each increment doubles the computation time.
✓ Security Best Practice: BCrypt automatically handles salt generation and is designed for password hashing. Unlike MD5/SHA, BCrypt is intentionally slow to prevent brute-force attacks.

Each generation produces a unique hash (different salt) even for the same password

Cost Factor: 10 | Estimated Time: ~100ms | Iterations: 1,024
What is BCrypt?

BCrypt is a password hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher. It's specifically designed for securely storing passwords.

Why Use BCrypt?
  • Adaptive: Cost factor can be increased as computers get faster
  • Salted: Automatically generates a random salt for each password
  • Slow by design: Intentionally computationally expensive to prevent brute-force attacks
  • Industry standard: Widely used and battle-tested for password storage
