Password hashing bcrypt Argon2id scrypt
Password Hash Generator
Generate test password hashes for bcrypt, Argon2id, scrypt, and PBKDF2. Use this for learning, fixtures, and parameter exploration.
Why Not SHA-256?
Plain hashes are too fast for password storage. Password hashes deliberately use salts and tunable cost settings.
Cost Settings
The defaults in this browser tool are for quick tests. Tune production cost, memory, and iteration settings on the server where login latency and hardware limits can be measured, using current OWASP or platform guidance as the baseline.
