An Evaluation of FNV Non-Cryptographic Hash Functions

We conduct an examination of the FNV family of non-cryptographic hash functions, with comparison to peer functions, across the standard suite of tests combined with commonly-used hash tables. The results obtained raise some interesting questions about evaluation and application of hash functions when considered alongside input type, goals and output distribution. In particular, we review the literature supporting the Avalanche criterion for assessing non-cryptographic hashes to understand why it is frequently referenced.
