14. One or more non-transitory media storing instructions that, when executed by one or more computing devices, cause performance of:generating one or more folded key values from a key value, each folded key value generated by folding sub-elements of the key value together;
constructing one or more addend values based on the one or more folded key values, each addend value generated by performing operations between a folded value and individual fields of a manipulation value, the folded value being derived from a particular folded key value of the one or more folded key values;
transforming a first value by performing an addition operation between the first value and one or more addend-based values, the one or more addend-based values being derived from the one or more addend values;
forwarding a network message based on an output of a hashing function, wherein either the first value is the output of the hashing function, or the transformed first value is an input to the hashing function.
