It handles modern and legacy ZIP formats including Deflate, Deflate64, Zip64 (files far beyond the approximate 4GiB limit), WinZip AES encryption, ZipCrypto password protection, and BZip2 compression\u2014formats that Python's standard zipfile module cannot always open. The library depends on pycryptodome for encryption and stream-inflate for decompression.\n\nThe package is designed for scenarios where ZIP files are too large to fit in memory or where you need to process files as they are extracted. It offers both synchronous and asynchronous interfaces (supporting asyncio and trio), making it suitable for streaming workflows in web services, data pipelines, and batch processing. Decryption of legacy ZipCrypto files is reported to be significantly faster than the standard library alternative.","worth_installing":"Yes. stream-unzip fills a genuine gap in Python's standard library by supporting encryption formats and compression methods the zipfile module cannot handle, while offering memory-efficient streaming for large archives. Active maintenance, no known vulnerabilities, permissive MIT license, and top-5000 PyPI popularity indicate a stable, trusted tool. Medium install friction is acceptable given the prebuilt wheels and lightweight runtime dependencies."},"id":"stream-unzip","links":{"html":"https://skillfed.io/packages/stream-unzip","md":"https://skillfed.io/packages/stream-unzip.md","pypi":"https://pypi.org/project/stream-unzip/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-03-03","license_spdx":null,"license_treatment":"permissive","name":"stream-unzip","python_support":"supports_current","summary":"Python function to stream unzip all the files in a ZIP archive, without loading the entire ZIP file into memory or any of its uncompressed files"},"popularity":{"monthly_downloads":876464,"position":4831,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.0.101"}
