fnv-c

What is it?

fnv-c is a Python 3.7+ FNV (fnv0, fnv1, fnv1a) non-cryptographic hash library implemented in C through libffi.

Features

• speed: 4 000% faster than basic Python implementation, 40% faster than pyhash
• portability:
  • tested with recent Python versions (3.7+)
  • compatible with ARM64 and avoid too agressive CPU optimizations
  • compatible with PyPy
• two variants: 32bits (fnv0_32()) and 64bits (fnv0_64())

Non features

• other hash algorithms (this library is about a specific algorithm)

How to install/use it?

pip install git+https://github.com/botify-labs/fnv-c.git#egg=fnv_c

import fnv_c

print(fnv_c.fnv0_32(b"foo bar"))
print(fnv_c.fnv0_64(b"foo bar"))
