This paper presents an empirical evaluation of a custom-designed hash function (NovaHash) using statistical randomness tests, diffusion metrics, and structural analysis. The goal of this study is not to propose a formally proven cryptographic primitive, but to investigate the behavior of a custom hashing mechanism under practical testing conditions. The evaluation includes collision resistance testing, bit distribution analysis, avalanche effect measurement, Strict Avalanche Criterion (SAC), Bit Independence Criterion (BIC), and performance benchmarking against standard implementations of SHA-256. Additionally, structural properties such as cycle behavior under iterative application are explored. Experimental results demonstrate strong statistical properties and diffusion characteristics comparable to standard hash functions. However, no formal claims of cryptographic security are made.
