Frequently asked questions

Is HMAC Generator free?

Yes. The core workflow is free, needs no account, and produces a usable result rather than a demo placeholder.

Does HMAC Generator upload my data?

Pasted data is processed locally unless the page explicitly checks a public URL through the protected API.

What limitation should I know about?

Do not paste production secrets into any online tool, even when processing is local.
