There is a widespread belief that a cryptographicly secure hash is needed. See: https://github.com/rurban/smhasher/blob/master/README.md#security

Beyond what is already documented in https://github.com/tkaitchuck/aHash/wiki/Attacking-aHash-or-why-it's-good-enough-for-a-hashmap
There should a wiki page should be created to explain:

  • How DoS attacks on hashes actually work and why even 'strong' hashes are susceptible.
  • What properties are actually needed.
  • How aHash satisfies these.

Should explain why standing up to impossible differential crypto analysis is not actually required.

It would also be good to walk through differential crypto analysis to show why input cancelation does not work on aHash.
