py-multihash

Multihash implementation in Python

• Free software: MIT license
• Documentation: https://multihash.readthedocs.io.
• Python versions: Python 3.10, 3.11, 3.12, 3.13, 3.14

Features

• Support for 125+ hash functions including:
  • Cryptographic hashes: SHA-1, SHA-2 (224/256/384/512), SHA-3, BLAKE2b, BLAKE2s, BLAKE3
  • Variable-length hashes: SHAKE-128, SHAKE-256
  • Non-cryptographic hashes: MurmurHash3 (32-bit and 128-bit)
  • Specialized hashes: Double-SHA-256 (Bitcoin), Keccak, and more
  • BLAKE2 variants: Full range of digest sizes (8-512 bits for BLAKE2b, 8-256 bits for BLAKE2s)
• Streaming hash computation for large files
• Hash truncation support
• JSON serialization
• MultihashSet collection type
• Go-compatible API (sum(), digest(), verify())

Quick Start

from multihash import digest, sum, Func

# Using modern hash functions
mh = digest(b"hello world", "blake3")

# Using MurmurHash3 for fast, non-cryptographic hashing
mh = digest(b"data", "murmur3-128")

# Using BLAKE2b with custom digest size
mh = digest(b"data", "blake2b-256")

# Go-compatible API
mh = sum(b"hello world", Func.sha2_256)
print(mh.encode('hex'))
