FAQ
Is the generator cryptographically secure?
Yes. It uses the Web Crypto API (crypto.getRandomValues), which is cryptographically secure — suitable for real secrets, API keys and signing tokens. Generation happens entirely in your browser, so the key never leaves your machine.
Are generated keys stored or sent anywhere?
No. Generation happens entirely in your browser — the key exists only on your screen and in your clipboard until you discard it.
What should I use the keys for?
Quick API-key placeholders, seed values, test tokens, random identifiers in config files — anywhere you need a random string fast and the stakes are low.
