The Mathematics Behind It
How do cryptographic HMAC limits secure data?
Hash-based Message Authentication Codes combine your standard algorithm iterations (like `SHA-512`) intertwined across a secret padding sequence. Because the private key isn't sent alongside payloads, web hooks block unauthorized impersonators.
