Verify the signature

Each request has a Konecto-Signature header: t=<timestamp>,v1=<hex HMAC-SHA256 of "timestamp.body"> with your endpoint secret. Reject requests older than five minutes.

import crypto from 'node:crypto';

export function verify(body: string, header: string, secret: string) {
  const [t, v1] = header.split(',').map((p) => p.split('=')[1]);
  const expected = crypto.createHmac('sha256', secret).update(t + '.' + body).digest('hex');
  const fresh = Math.abs(Date.now() / 1000 - Number(t)) < 300;
  return fresh && crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(v1));
}
