WebTesting 64-bit hashes on small inputs : The test on input 8 bytes => 8 bytes output can check if there is some "space reduction" happening at this length. If there is no space reduction, then the transformation is a perfect bijection, which guarantees no collisions for 2 different inputs. Other lengths : Testing 128-bit hashes : WebOverall, the golden ratio for two values ( a and b) is defined as: a + b a = a b = def φ For this, we could have a 64-bit hash range, and where we can divide by the golden ratio value ( φ) of: φ = 1 + 5 2 = 1.618033989... to determine a multiplier for the hash: f i b = 2 64 φ ≈ 11400714819323198485 WebAug 16, 2024 · HighwayHash64 6242.58 99.55 248.41 SipHash 980.88 127.77 246.19 So, for security, SipHash looks strong, and for speed, with a reduced security level, HighwayHash looks strong.

HighwayHash is a new way of mixing inputs which may inspire new cryptographically strong hashes. Large inputs are processed at a rate of 0.24 cycles per byte, and latency remains low even for small inputs. HighwayHash is faster than SipHash for all input sizes, with 5 times higher throughput at 1 KiB. See more To build on a Linux or Mac platform, simply run make.
