SevenZipFile ( 'sample.7z', mode = 'r' ) archive. Here is a code snippet how to decompress some file in your application. Py7zr is a library which can use in your python application. $ py7zr -version SevenZipFile Class Usage You can run command script py7zr like as follows OR, alternatively using conda: $ conda install -c conda-forge py7zr Documents User manualsĬontributor guide for one want to contribute the project. You can install py7zr as usual other libraries using pip. It is disabled on PyPy.īCJ2 (Standard lzma module does not provide). Not to be compatible with original 7-zip on windows/p7zip on linux/mac.Įnhanced Deflate is also known as DEFLATE64 TM that is a registered trademark of PKWARE, Inc.Įnhanced Deflate is tested only on CPython. ZStandard and Brotli is not default methods of 7-zip, so these archives are considered Py7zr try checking symbolic links strictly and raise ValueError when bad link is requested,īut it does not guarantee to block all the bad cases. Supported algorithmsĪ feature handling symbolic link is basically compatible with p7zip implementation,īut not work with original 7-zip because the original does not implement the feature. Py7zr is also able to encrypt and decrypt data using 3rd party encryption library.
It also supports ZStandard, Brotli and PPMd with third party libraries. Py7zr supports algorithms and filters which lzma module and liblzma support,Īnd supports BZip2 and Deflate that are implemented in python core libraries, Matteo Cosentino for notification and coorporation on security improvement. You are recommend to update immediately to version 0.20.2 or later, 0.19.2 or 0.18.12 Īffected versions are vulnerable to Directory Traversal due to insufficient checks in the ‘py7zr.py’ and ‘helpers.py’ files Version 0.20.0, 0.19.0, 0.18.10 or before has a vulnerability for path traversal attack.ĭetails are on “CVE-2022-44900: path traversal vulnerability in py7zr” disclose article.
Py7zr is a library and utility to support 7zip archive compression, decompression,Įncryption and decryption written by Python programming language.
