This tool measures "Information Entropy" (measured in bits). It analyzes the pool of characters you used (uppercase, lowercase, numbers, symbols) and the length of the string. It then calculates how many seconds it would take a massive GPU cluster (guessing 10 billion times per second) to brute-force that specific combination.

Yes. This tool is "Client-Side Only." That means the math runs entirely in your web browser using JavaScript. No data is sent to our servers, and we do not store logs. You can even disconnect your internet (WiFi/Ethernet) and the tool will still function perfectly.

Hackers don't guess passwords manually; they use automated scripts. A password like "Password123" can be cracked in 0.00001 seconds. By adding just one special symbol (like # or !), you can increase the cracking time from hours to centuries.
