Secret Generator

About Secret Generator

Generate cryptographically secure random strings — hex, base64, base64url, alphanumeric — for API keys, session secrets, OAuth tokens, JWT keys, CRON_SECRET, and database passwords. Includes one-click presets for common use cases (AUTH_SECRET, JWT key, etc.) and the equivalent terminal command for each output so you can reproduce it on any machine with `openssl`. Uses the browser's WebCrypto API — secrets are never sent to any server.
