|
|
xxHash is an Extremely fast Hash algorithm, running at RAM speed limits.
|
|
It successfully completes the SMHasher test suite which evaluates
|
|
collision, dispersion and randomness qualities of hash functions. Code is
|
|
highly portable, and hashes are identical on all platforms (little / big
|
|
endian).
