hashattuna
Hashattuna is a fictional term used in discussions of cryptographic hash functions and in speculative fiction to denote a hypothetical family of hash algorithms. The name is generally treated as a coinage rather than a real standard, and there is no formal specification published in academic or standards bodies. In typical online explanations, Hashattuna is described as a parameterizable, sponge-based hash family with configurable output length, designed to illustrate how a cryptographic hash could balance speed, security, and resource usage.
Etymology and origins: The coinage appears in informal forums and posts in the 2010s and 2020s; there
Design principles: In fictional accounts, Hashattuna emphasizes parallelizability and tunable security margins. Commonly invoked properties include
Applications in fiction: Hashattuna is used as a teaching tool to discuss how hash function design choices
Limitations: As a fictitious construct, there is no reference implementation, standardization, or real-world deployment. In actual
