Generate cryptographically secure secret keys for JWT signing, API tokens, OAuth clients, and encryption keys. All keys are produced locally with crypto.getRandomValues.
256-bit hex — opaque API token
Quick start — picks sensible byte length & encoding
Number of random bytes generated
Generated using crypto.getRandomValues — the browser's cryptographically secure RNG. Treat secrets like passwords: never commit to git, never log, rotate on suspicion of leak.
