Offers 32- 64- and 128-bit oneshot and incremental hashes. # License > Licensed under the MIT license. See the LICENSE file in the repository root for more details. # Usage ## Oneshot Hashes ```python >>> import spookyhash >>> spookyhash.hash32(b'hello world') 2617184861 >>> spookyhash.hash32(b'hello world', seed=0x12345678) 3380090220 >>> spookyhash.hash64(b'hello world') 14865987102431973981 >>> spookyhash.hash64(b'hello world', seed=123) 5719863273689036421 >>> spookyhash.hash128(b'hello world') 185933735475381961281710998418114941533 >>> spookyhash.hash128(b'hello world', seed1=123_000, seed2=456_000) 144121310386202441278894605216246194925 >>> # For a more comparable result to other libraries >>> spookyhash.hash128_pair(b'hello world') (14865987102431973981, 10079487997037711397) >>> spookyhash.hash128_pair(b'hello world', seed1=123_000, seed2=456_000) (12678109464562819821, 7812831891108919044) ``` ## Incremental Hashes ```python >>> import spookyhash >>> sh = spookyhash.Hash32() >>> sh.update(b'hello') >>> sh.update(b' ') >>> sh.update(b'world') >>> sh.final() 2617184861 >>> spookyhash.Hash64(b'hello ', seed=123).update(b'world').final() 5719863273689036421 >>> sh = spookyhash.Hash128(seed1=123_000, seed2=456_000) >>> sh.update(b'hello world') >>> sh.final() 144121310386202441278894605216246194925 >>> sh.final_pair() (12678109464562819821, 7812831891108919044) ``` # Platform Independence If run on a big-endian system, the code would produce different hashes, but of equal quality.
