Entropy, crack time & weakness analysis — computed privately in your browser — by Dinal Studios
Type a test password below. Analysis updates as you type: entropy, pattern weaknesses, and how long different attackers would need to crack it.
Average time to guess half the possibilities, under five attack models. Real attackers start with dictionaries and patterns — which is why the pattern findings below matter more than raw length.
| Attack scenario | Guesses / second | Estimated time |
|---|---|---|
| Online attack, throttled by the website | 100 / hour | — |
| Online attack, no throttling | 10 / second | — |
| Offline attack on a slow hash (bcrypt-style) | 10 thousand / second | — |
| Offline attack on a fast hash (GPU rig) | 10 billion / second | — |
| Massive parallel attack (botnet / nation-state) | 1 trillion / second | — |
The exact patterns cracking tools (like Hashcat rule sets) try first — after the top-10-million password lists.
