miniswhid 0.1.1

No-frills SWHID computation for files and directories

miniswhid

No-frills Software Hash Identifier (SWHID) computation for files and directories.

Features

• Support for content (cnt) and directory (dir) SWHIDs
• Concurrent file hashing on multi-core systems
• Minimal dependencies — uses only Python standard library

Revision, release and snapshot SWHIDs are not supported.

Requirements

• Python 3.10 or higher

Installation

pip install miniswhid

Quick Start

Command Line

# Compute SWHID for a file
miniswhid README.md
# Output: swh:1:cnt:4c7fdf8...

# Compute SWHID for a directory  
miniswhid /path/to/directory
# Output: swh:1:dir:8b137891...

Python API

from miniswhid import compute_content_swhid, compute_directory_swhid

# File content SWHID
file_swhid = compute_content_swhid("README.md")
print(file_swhid)  # swh:1:cnt:4c7fdf8...

# Directory SWHID
dir_swhid = compute_directory_swhid("/path/to/directory")  
print(dir_swhid)   # swh:1:dir:8b137891...

Acknowledgements

This project's test suite uses reference SWHID values generated by the Software Heritage toolchain (swh identify) to ensure correctness and compatibility with the official implementation.
