Think like a hacker. Defend like a pro. — by Dinal Studios
Type a password to see its entropy, how long real attackers would need to crack it, and every weak pattern hiding inside it. Nothing you type ever leaves this page.
Breach check uses k-anonymity: only the first 5 characters of the password's SHA-1 hash are sent to the Have I Been Pwned range API — your password itself never leaves your device.
Generated locally with your device's cryptographic random engine — the same technology banks rely on.
Passphrases (like tiger-planet-7-coffee-river) are long, memorable and extremely hard to crack — the smartest choice for accounts you type often.
Ethical hackers (white hats) find security holes before criminals do — with permission. These are the 5 classic phases every cyber security professional learns:
Gathering public information about a target system to understand its attack surface.
Finding open ports, services and known weaknesses with security scanners.
Testing whether a weakness can actually be exploited — in a lab or with written permission.
Checking if an attacker could stay hidden inside — so defenders can close the door.
Documenting every finding so the owner can fix it. This report is the real product of ethical hacking.
The vocabulary of the security world, in plain words.
