Hash functions are a crucial component in cryptography, data integrity, and security. They take an input (or 'message') and produce a fixed-size string of characters, known as a 'hash value' or 'digest.' This process is one-way, meaning it's computationally infeasible to recreate the original input from the hash value. Hash functions are used in a variety of applications, including data integrity checks, digital signatures, and password storage. Please provide feedback on the scope defined above

KATU128 is (if you have the key) — meaning you can verify without recomputing from scratch on long messages. That’s rare for lightweight MACs. It behaves like a block cipher in chaining mode but without the overhead.
