KASSPAR / plain-language security education
Security you can actually understand.
Most people get hacked in boring ways: a reused password, a convincing email, an update that never got installed. Kasspar explains how real attacks work in everyday language and gives you tools to test yourself, so you and the people around you become genuinely harder to hack.
No jargon without a translationEvery term is explained the first time it appears, and again in the glossary.
No fear, only prioritiesYou cannot do everything. We tell you which few habits stop most attacks.
Nothing leaves your browserEvery tool on this site runs locally. What you type is never sent anywhere.
TOOLS / interactive, offline, nothing stored
Six tools that show you what an attacker sees.
Each one runs entirely in this browser tab. Type real things into them if you like; nothing is sent, logged or kept.
AnalysePassword labType a password and see the checks a cracking tool runs first: patterns, leaked-list hits, effective bits, offline time-to-crack.
CheckLeak checkerTest a password against a bundled list of the 1,500 most common breached passwords, plus near-matches, without it leaving your browser.
GeneratePassword & passphrase generatorRandom passwords and diceware-style passphrases from your browser's cryptographic random source, with the entropy shown.
InspectPhishing-URL inspectorPaste a link. It is taken apart as text, never opened, and the classic tricks are flagged with plain explanations.
