Password Entropy And Crack Time Calculator
Password Entropy And Crack Time: a planned Super Calculator tool. Covers password length (n). Stub page while the tool and its worked example are prepared.
Password Entropy And Crack Time Calculator is a planned calculator in the technology section of Super Calculator, covering crypto mining and energy.
What this calculator will compute
Inputs: password length (n), character set (label), guess rate (guesses/s) and hashing algorithm (label).
Outputs: entropy (bits), search space (n), estimated crack time (label) and strength band (label).
Formula, recorded as scope and not yet verified against a primary source: Entropy in bits equals length times log base 2 of the character set size for a randomly generated password. That model is invalid for human-chosen passwords, where realistic strength is estimated from dictionary and pattern matching, and crack time equals 2 to the entropy divided by the guess rate.
