Katu128 Fixed May 2026

Katu128 was initially designed to be a high-performance hash function, optimized for 128-bit output. It was intended for use in various cryptographic protocols, including digital signatures, message authentication codes (MACs), and key derivation functions. The original Katu128 algorithm showed promise with its high-speed hashing capabilities. However, upon further scrutiny, researchers identified potential weaknesses that could compromise its security.
