This generator uses the browser's Web Crypto API to produce unpredictable output directly on the client. The standard generator limits characters to alphanumeric values for compatibility, while the enhanced generator introduces special characters to increase entropy and strengthen the resulting secret.

Frequently asked questions
How secure is the secret generation process?+
Generation uses window.crypto.getRandomValues in the browser. That means the output is cryptographically secure and does not require server-side processing.
Should I use special characters for API keys?+
For some systems, alphanumeric-only keys are easier to integrate. For maximum entropy, use the enhanced generator with special characters whenever your platform supports it.
Where should I store an API key after generating it?+
Use a secrets manager or encrypted environment variables. Avoid chat apps, plain text files, and committed source code.
