Frequently Asked Questions

Is my data sent to a server when using the Password Strength Analyser?
No. The Password Strength Analyser is a fully client-side utility. All data processing, calculations, and conversions are handled locally in your browser. No input text, payloads, or keys are uploaded to any external server.
How is random entropy gathered for generation?
The generator fetches highly secure, unpredictable random numbers directly from the browser's Cryptographically Secure Pseudo-Random Number Generator (CSPRNG) API via `window.crypto.getRandomValues`.
Can I run this utility offline?
Yes. Once loaded, the cryptographic generator has zero external library or API dependencies, allowing you to generate seeds, keys, and hashes offline.
Can these generated keys be cracked by brute force?
Outputs generated with standard parameters (e.g. UUIDv4, Bcrypt with high cost, or high-length passwords) are mathematically resistant to standard modern brute-force dictionaries.
Does the Password Strength Analyser store history or cache my inputs?
No. The application runs entirely in browser memory. Once you refresh the tab, navigate away, or close the window, all inputted details, logs, and outputs are completely cleared.
Is the Password Strength Analyser compatible with mobile devices?
Yes. The interface is optimized to be fully responsive. You can perform calculations, conversions, and formats on all modern mobile, tablet, and desktop web browsers.
Does the Password Strength Analyser work offline?
Yes. Once loaded, all code and assets required to run the Password Strength Analyser reside in your browser cache, enabling offline use without an active network connection.
