It maintains the same API as Python 3.7's zipfile, so existing code using standard zipfile can often switch to pyzipper with minimal changes to add encryption support.\n\nThe package depends on pycryptodomex for cryptographic operations and supports AES encryption at 128, 192, or 256 bits (256 bits by default). It handles password-based encryption, CRC32 validation for data integrity, and follows WinZip's AES FAQ recommendations\u2014notably, it excludes CRC32 values from encrypted file headers by default to avoid leaking information about small files, though this can be conditionally enabled for files above a configurable byte threshold.","worth_installing":"Yes. pyzipper is actively maintained, has no known vulnerabilities, installs with minimal friction, and solves a real gap in Python's standard library\u2014AES encryption for zip files. The MIT license is permissive. Use it when you need encrypted zip support; the API is familiar to anyone who has used zipfile, and the single dependency is lightweight."},"id":"pyzipper","links":{"html":"https://skillfed.io/packages/pyzipper","md":"https://skillfed.io/packages/pyzipper.md","pypi":"https://pypi.org/project/pyzipper/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-14","license_spdx":"MIT","license_treatment":"permissive","name":"pyzipper","python_support":"supports_current","summary":"AES encryption for zipfile."},"popularity":{"monthly_downloads":9323147,"position":1544,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.4.0"}
