KMAC: Keccak Message Authentication Code

KMAC (Keccak Message Authentication Code) is a keyed-hash message authentication code (MAC) based on Keccak and defined in NIST SP 800-185. It provides a way to verify both the integrity and authenticity of a message using a secret key.

Unlike standard hash functions which are public, KMAC requires a secret key. This means only someone with the key can generate the correct hash for a given message, preventing attackers from tampering with the data.

Why use KMAC?

Authentication: Verifies that the message came from a trusted source (who holds the key).
Efficiency: Generally faster and more efficient than HMAC-SHA2 constructions.
Security: Built on the robust security of the Keccak sponge construction.
