HMAC Generator mini guide
HMAC Generator lets you sign a message with a shared key using SHA-1, SHA-256, or SHA-512 so you can verify payloads and debug signature flows without leaving the browser.
How to use it
- 1Enter the shared secret and the message body you want to sign.
- 2Choose the hash algorithm and the output format that matches your integration.
- 3Generate the signature, then copy the result into your request, docs, or test fixture.
What it is good for
- • Webhook verification and API signature debugging.
- • Creating reproducible signed examples for docs, QA, and support work.
- • Quick validation before you move the logic into backend code.
