murmurhash2 for Python
Decision gist · record as of 2026-08-14
Yes, if you specifically need MurmurHash2 or MurmurHash3 for compatibility or performance in a non-security context. No, if you are looking for an actively maintained hashing library or need cryptographic guarantees. The abandoned status and lack of recent updates mean no security patches will be issued if issues arise.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires prebuilt wheel matching your Python version, architecture, and OS; no pure-Python fallback.
- Medium install friction due to compiled wheels; prebuilt binaries available for common platforms (x86_64, ARM, PowerPC, s390x on Linux/macOS/Windows) but requires matching your architecture.
- Last release was 2022-02-12 and the project is marked abandoned, so no active maintenance.

What it is and what it does
murmurhash2 is a Python binding to the MurmurHash2 and MurmurHash3 C implementations, providing fast non-cryptographic hash functions for byte strings. It exposes two functions—murmurhash2() and murmurhash3()—each taking a byte string and an optional seed value, returning a 32-bit hash. The package is distributed as precompiled wheels for common platforms and Python versions, with no runtime dependencies.
This is a low-level hashing utility, not a cryptographic library. It is typically used in scenarios where you need fast, deterministic hashing of data and do not require collision resistance or security properties. The project has been abandoned since its latest release on 2022-02-12, so it receives no active maintenance or updates.
Use it for
- Hash-based data structures like hash tables or hash sets where speed matters more than cryptographic strength
- Bloom filters or other probabilistic data structures that require a fast, seeded hash function
- Distributed systems or load balancing that need consistent hashing with a seed for reproducibility
- Legacy code migration where MurmurHash2 or MurmurHash3 output must match existing implementations
