API Key Generator
Generate random API-key-shaped strings for placeholder/test use.
Generates random API-key-shaped strings (sk_ prefix + 32 alphanumeric characters) using crypto.getRandomValues() — for placeholder/test use, not a real credential. Runs entirely in your browser.
What is API Key Generator?
Generates random strings shaped like a typical API key (a short prefix plus 32 random alphanumeric characters), using crypto.getRandomValues() — the same cryptographically secure random source browsers use for things like session tokens — for placeholder UI mockups or test fixtures, not a real credential your service should actually issue. It's useful anywhere you need a realistic-looking key without wiring up a real auth backend yet: seeding a demo dashboard, populating a `.env.example` file, or writing a test fixture that expects an API-key-shaped string. Everything runs in your browser — nothing you generate here is sent anywhere or logged.
FAQ
No — generate real API keys server-side using your own service's key-issuing logic and proper storage/hashing. This tool is for placeholder/test use only.
Yes — it uses the browser's crypto.getRandomValues() rather than Math.random(), so the characters aren't predictable from previous output. That said, a real API key also needs server-side issuance, storage, and revocation logic, none of which this tool provides.
No — generation happens entirely in your browser. Nothing is transmitted to a server or saved once you leave the page.
