About bcrypt
- bcrypt is a password hashing function designed to be slow and memory-hard β resistant to brute-force attacks even with GPUs
- The cost factor (rounds) determines how slow: each +1 doubles the work. 10 is a typical default; 12+ is recommended for sensitive systems in 2024
- Each hash includes a random salt automatically, so the same password produces different hashes every time β this is by design
- All hashing runs locally via bcryptjs library β passwords never leave your browser
Use cases
- Generate test password hashes for development databases
- Verify a hash from a backup against the original password
- Reproduce specific hash values for unit tests
