FAQ

How does the analyzer estimate brute-force cracking duration?

It calculates information entropy from character set combinations and models cracking time against modern GPU hash cluster speeds.

Is it safe to test my real personal passwords here?

Yes. The evaluation script operates 100% locally in your client browser sandbox without transmitting input over the internet.

What is the most effective way to strengthen a password?

Increase length above 14 characters, eliminate predictable keyboard patterns, and mix diverse character sets or employ multi-word passphrases.
