How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

Crack time is estimated from the total search space, attacker guesses per second, and the share of that space expected to be checked. It is a scenario model, not a guarantee of safety.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

Should users enter real passwords?

No. Test password patterns only, not sensitive real passwords.

Is crack time exact?

No. It is an estimate based on assumptions about attacker capability.
