No, sorry, that is a completely different use case. Crypto hashes are
used, among other things, in network communications, persistent
storage, etc. They need to be "fixed" functions, and their standards
provide the exact definition. That is not the case at all with
std::hash or Boost.Hash.

For debugging purposes, a fixed function seems quite useful to me.
