Estimated time to crack (average case)

ScenarioGuessing speedTime
How it works: strength combines length, character variety and entropy (randomness), then penalises common passwords, keyboard walks, sequences like “1234”, repeated blocks and embedded years. Crack times assume the attacker guesses half the keyspace on average. Privacy: the check runs entirely in your browser — your password is never sent to any server, logged or stored.
