HMAC-SHA256 Webhook Signatures (X-DvC-Signature) & SSRF Guard

Every webhook POST sent by DaVinci Deluxe Cloud Edition includes `X-DvC-Signature: sha256=<hex_digest>` computed over the raw UTF-8 request body with your `whsec_...` webhook secret, plus `X-DvC-Event: job.completed | job.failed`. For SSRF security, `webhook_url` must use `https://` on one of your registered portal domains and resolve to a public routable IP.

Production Reference Implementation

import crypto from 'node:crypto';

export function verifyDavinciWebhook(rawBodyBuffer, sigHeader, webhookSecret) {
  const expected = 'sha256=' + crypto
    .createHmac('sha256', webhookSecret)
    .update(rawBodyBuffer)
    .digest('hex');
  const a = Buffer.from(String(sigHeader || ''), 'utf8');
  const b = Buffer.from(expected, 'utf8');
  return a.length === b.length && crypto.timingSafeEqual(a, b);
