Generate Hashes for API Request Signing

Understand HMAC signing by computing the hash of your API payload before sending signed requests.

Tip: SHA-256 and SHA-512 are cryptographically secure. SHA-1 is legacy and no longer recommended for security-sensitive use. All hashing runs locally in your browser — files and text are never sent anywhere.

API Signing tips

✍️

Many APIs (AWS, Stripe, Twilio) use HMAC-SHA256 to sign requests. The signature is a hash of the request body combined with your secret key.

💡

Use this tool to verify what your request payload's raw SHA-256 hash looks like before the HMAC layer is applied.

🔍

If your signed request is being rejected, hash the raw payload here and compare it to what your signing implementation produces.

📋

Webhook providers like GitHub send an X-Hub-Signature-256 header. Compute the SHA-256 hash of the raw webhook body to verify it matches.
