Advanced Security Features

Implementing advanced HMAC verification for client-side integrations and improved rate limiting.

Security is our top priority. This update introduces new mechanisms to protect your usage and quota.

New Security Features

  • HMAC Verification: You can now sign client-side requests using your secret key to prevent authorized usage.
  • Strict Rate Limiting: Configure custom rate limits per IP or per Token to prevent abuse.
  • Audit Logs: View detailed logs of all security events and access attempts in the dashboard.

Implementation Guide

To enable HMAC verification, update your client initialization:

const client = new CaptchaSonic({
  apiKey: '...',
  hmacKey: process.env.SONIC_HMAC_KEY, // New
});
