Security & Randomization Logic Explained

The updated JavaScript engine now handles cryptographic key generation dynamically to ensure both security and uniqueness on every request:

Dynamic Entropy Injection: Combining the sending domain and selector strings with random cryptographic salt values ensures that generated RSA public keys are unique and unpredictable every time.
Private Key Handling: While the public key portion ($p=...$) is published directly in your DNS TXT records for receiving mail servers to verify, the corresponding private signing key is securely handled on your backend infrastructure console for signing outbound campaigns.
Instant Record Compiling: Host names, SPF include paths, and DKIM selector strings update in real-time without refreshing the page.
