 ### Zero Allocation
 
-The fastest use of this algorithm is to simply call `SipHasher.hash/2` which will call a zero-allocation implementation of the SipHash algorithm. This implementation should be used in most cases; specifically cases where you have frequently differing seed keys.

-By default, as of v2.0.0, all hashes are returned as a `long`. However, you can use `SipHasher.toHexString/1` to convert a hash to a hexidecimal String value.
