What is Password Length Estimator

The Password Length Estimator calculates the time required to brute-force a password given its length and character set. It uses current computing speed estimates for different attack scenarios: offline hash cracking with GPU clusters (billions of attempts/second), online rate-limited attempts (hundreds/second), and air-gapped hardware attacks.
