This package aims to provide faster zlib and gzip compatible compression and decompression by implementing Python bindings for the ISA-L library.

The inflate64 package provides Deflater and Inflater classes to compress and decompress with the Enhanced Deflate compression algorithm.

This package provide a Python wrapper to EWAH compression bitarray method.

This package provides a pathlib-compatible Zipfile object wrapper. It provides a backport of the Path object.

PPMd is a compression algorithm library using the Prediction by Partial Matching statistical technique. It is used in RAR and 7-Zip as one of several possible methods.

Bitshuffle is an algorithm that rearranges typed, binary data for improving compression, as well as a python/C package that implements this algorithm within the Numpy framework.

This package provides a modern and easy to use streamable zip file generator

Bitshuffle is an algorithm that rearranges typed, binary data for improving compression, as well as a python/C package that implements this algorithm within the Numpy framework.

This package provides Python bindings to the Zstandard (zstd) compression library. The API is similar to Python's bz2/lzma/zlib module.

Python-LZO provides Python bindings for LZO, i.e. you can access the LZO library from your Python scripts thereby compressing ordinary Python strings.

Blosc2 is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() system call.

Python-Blosc2 wraps the C-Blosc2 library, and it aims to leverage its new API so as to support super-chunks, multi-dimensional arrays, serialization and other features introduced in C-Blosc2.

Python-Blosc2 also reproduces the API of Python-Blosc and is meant to be able to access its data, so it can be used as a drop-in replacement.

Bitshuffle is an algorithm that rearranges typed, binary data for improving compression, as well as a python/C package that implements this algorithm within the Numpy framework.

This project provides Python bindings for interfacing with the Zstandard compression library. A C extension and CFFI interface are provided.

Blosc is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() system call.

Blosc works well for compressing numerical arrays that contains data with relatively low entropy, like sparse data, time series, grids with regular-spaced values, etc.

This Python package wraps the Blosc library.

MultiVolumefile is a Python library that provides a file-object abstraction, making it possible to use multiple files as if they were a single file.

This package implement a pure Python module for uncompressing LZW files (.Z), such as the ones created by Unix's shell tool compress.

Lz-string is a string compressor library for Python.

This package provides py7zr, which implements 7-zip archive compression, decompression, encryption and decryption in Python.

pylsqpack is a wrapper around the ls-qpack library. It provides Python Decoder and Encoder objects to read or write HTTP/3 headers compressed with QPACK.

python-secretstorage provides a way for securely storing passwords and other secrets. It uses D-Bus Secret Service API that is supported by GNOME Keyring (since version 2.30) and KSecretsService. SecretStorage supports most of the functions provided by Secret Service, including creating and deleting items and collections, editing items, locking and unlocking collections (asynchronous unlocking is also supported).

This package provides a Python implementation of the JOSE protocol (Javascript Object Signing and Encryption).

cryptography is a package which provides cryptographic recipes and primitives to Python developers. It aims to be the “cryptographic standard library” for Python. The package includes both high level recipes, and low level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests and key derivation functions.

This package provides Ed25519 public-key signatures in Python.

The Stateless OpenPGP Command-Line Interface (or sop) is a specification that encourages OpenPGP implementors to provide a common, relatively simple command-line API for purposes of object security.

This Python module helps implementers build such a CLI from any implementation accessible to the Python interpreter.

It does not provide such an implementation itself -- this is just the scaffolding for the command line, which should make it relatively easy to supply a handful of python functions as methods to a class.
