KMAC
Keccak Message Authentication Code
KMAC (NIST SP 800-185) is a keyed message authentication code built on cSHAKE. Enter a key, the message and an optional customization string to get a MAC of the length you choose, for text or for a file. Use KMAC256 for 256-bit security; classic HMAC tools are in the Encryption category.
