Security Tools
Cryptographically secure security utilities that run entirely in your browser — password generator, entropy analysis, and more.
Why Use Security Tools?
Privacy-first security utilities that never transmit secrets over the network. Every tool uses browser-native WebCrypto primitives (crypto.getRandomValues, SubtleCrypto) so generated passwords and derived keys stay on your device. No accounts, no logs, no telemetry — close the tab and nothing remains. Built for IT administrators, developers, and privacy-conscious users who refuse to paste sensitive material into third-party services.
Frequently Asked Questions
Where do generated passwords come from?
All randomness comes from the browser's crypto.getRandomValues() — the same primitive used by HTTPS and WebCrypto. No Math.random anywhere in the code path.
Are passwords ever stored?
No. Generated passwords live only in the current tab. The session history is kept in memory and cleared on reload; nothing is written to localStorage or sent to a server.
What does the clipboard auto-clear do?
After copying a password, the clipboard is overwritten with an empty string 60 seconds later to reduce the risk of other applications reading it.
Can I export bulk passwords?
Yes. The bulk mode produces up to 100 passwords at once and exports them to a .txt file. The file is generated client-side as a Blob — no upload.
