Yes, they're all cryptographic hash functions for now.

The concepts would definitely allow models that are not cryptographic.
 One problem I foresee there is that I didn't have enough models of a
message digest to distill a concept, so they currently return an
instance of a specific digest template.  Because that digest template
is algorithm-independent, there is a slight cost involved in the
conversion from the internal state.  That cost is lost in the noise
for the more expensive cryptographic hashes, but might be a problem
for the much faster non-cryptographic hashes.

I'd love to generalize it further; Do you have a list of
non-cryptographic hashes you'd like to see?
