Sicherheit: X-Webhook-Signature

hash_hmac('sha256', $body, $webhookSecret)

• $body: Der ungeänderte JSON Body der Webhook-Anfrage (als String)
• $webhookSecret: Dein geheimer Schlüssel für diesen Webhook

Beispiele

$body = file_get_contents('php://input');
$signature = $_SERVER['HTTP_X_WEBHOOK_SIGNATURE'] ?? '';

    http_response_code(401);
    exit('Invalid signature');
}

// Verarbeitung ...
http_response_code(200);
echo 'OK';

using System.Security.Cryptography;
using System.Text;

string body = await new StreamReader(Request.Body).ReadToEndAsync();

{
    var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(body));
    var expected = BitConverter.ToString(hash).Replace("-", "").ToLower();

    if (expected != signature)
    {
        return Results.Unauthorized();
    }
}

// Verarbeitung ...
return Results.Ok();

        const signature = req.headers['x-webhook-signature'];
        const expected = crypto
        .createHmac('sha256', webhookSecret)
        .update(req.body)
        .digest('hex');
