It wraps support for 125+ hash functions\u2014including cryptographic algorithms (SHA-1, SHA-2, SHA-3, BLAKE2, BLAKE3), variable-length hashes (SHAKE-128/256), and non-cryptographic options (MurmurHash3)\u2014behind a unified interface. The package provides streaming computation for large files, hash truncation, JSON serialization, and a Go-compatible API (sum, digest, verify methods).\n\nTypical use cases include content-addressed storage systems, distributed systems that need portable hash identification, and applications requiring interoperability with Go-based multihash implementations. The package depends on six runtime libraries: varint, six, morphys, base58, blake3, and mmh3. It is maintained as a Pre-Alpha project but has been in development since 2018 and remains actively used.","worth_installing":"Yes, with conditions. The package is permissively licensed, has low install friction, and supports current Python versions. However, its Pre-Alpha status and aging maintenance (240 days since last release, last commit 2026-01-05) mean it is not actively developed. Install if you need multihash interoperability or Go-compatible hash APIs; avoid if you require active maintenance or stability guarantees."},"id":"py-multihash","links":{"html":"https://skillfed.io/packages/py-multihash","md":"https://skillfed.io/packages/py-multihash.md","pypi":"https://pypi.org/project/py-multihash/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-12-17","license_spdx":"MIT","license_treatment":"permissive","name":"py-multihash","python_support":"supports_current","summary":"Multihash implementation in Python"},"popularity":{"monthly_downloads":162401,"position":10606,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"3.0.0"}
