spooky_hash 1.0.1

Python wrapper for SpookyHash V2

SpookyHash is a public domain noncryptographic hash function producing well-distributed 128-bit hash values for byte arrays of any length.1

This python library is a Cython wrapper for the original C++ implementation. There are both (fast) one-shot hash functions and (slower) hashlib-like hash objects.

Usage

>>> import spooky_hash
>>> print spooky_hash.hash32('hello world')
2617184861
>>> print long(spooky_hash.Hash32('hello ').update('world'))
2617184861

>>> print spooky_hash.hash64('hello world')
14865987102431973981
>>> print long(spooky_hash.Hash64('hello ').update('world'))
14865987102431973981
>>> print spooky_hash.Hash64('hello ').update('world').hexdigest()
