### Validar Assinatura HMAC de Webhook

Source: https://waterpag.com/docs

Função TypeScript que verifica a assinatura HMAC-SHA256 de um webhook. Valida o formato da assinatura, o timestamp (tolerância de 5 minutos) e usa timingSafeEqual para comparação segura.

```typescript
import crypto from 'node:crypto'

export function verifyWebhook(rawBody, signature, timestamp, secret) {
  const expected = crypto
    .createHmac('sha256', secret)
    .update(`${timestamp}.${rawBody}`)
    .digest('hex')

  const time = Date.parse(timestamp)
  if (typeof signature !== 'string' || !/^[a-f0-9]{64}$/.test(signature) || !Number.isFinite(time) || Math.abs(Date.now() - time) > 5 * 60 * 1000) {
    return false
  }

  return crypto.timingSafeEqual(
    Buffer.from(signature),
    Buffer.from(expected),
  )
}
```
