Length beats complexity
A long random passphrase usually outperforms a short password with symbols. Use a password manager and unique passwords.

Password Cracking Time Calculator
Estimate brute-force cracking time based on hash type, attacker hardware, password length, and character set.
Attack model
Choose a hash family and hardware profile; the table updates immediately.
Maximum time for a complete brute-force search. Human-chosen passwords can be weaker than the same length suggests.
| Length | 0-9 | a-z | a-z, A-Z | a-z, A-Z, 0-9 | a-z, A-Z, 0-9, symbols |

< 1 sec (Cracked)
Offline hashes only
The model assumes an attacker already has the hash and can test guesses locally. Online logins behave very differently.
Prefer slow hashes
bcrypt, Argon2id, scrypt, and high-cost PBKDF2 make every guess expensive and change the table dramatically.
