f2568()

What is this?

f2568() is a variable length tabulation hashing function which
returns a 64 bit hash result of input data up to a size of 256
bytes. It’s quite fast (basically requiring as many XOR operations
as the data length in bytes), easy to understand and very strong
at the same time.

f2568() is publicly available under the BSD-3-Clause License.

Being a tabulation hash function, it’s not 4-independent, which can
safely be ignored for the intended purposes.
