This library provides a deterministic hash for Python objects. hash will give different results each process invocation, in order to thwart denial-of-service attacks based on intentionally triggering hash collisions (see -R in Python’s CLI options). Even setting PYTHONHASHSEED is not enough, because the hash can still use non-deterministic data such as pointer-addresses. By default, this package uses the xxhash algorithm, which is the fastest non-cryptographic hash I know of.
