This package provides a library for encoding and decoding ZIP archive format's "Extra Fields". The intention is to eventually support and provide a low-level API for the majority of PKWARE's and Info-ZIP's extra fields.

This package provides some Golang interfaces for handling RPM packages, such extracting RPM header and CPIO content.

This package implements parallel gzip compression and decompression in Golang and is fully compatible with compress/gzip from the standard library. This is beneficial for large amounts of data, say more than 1MB at a time, as otherwise the internal gzip library will likely be faster.

This package provides a Go wrapper to zstd C library.

Package xz implements XZ decompression natively in Go.

This package implements a seekable version of gzip-format compressed files, compliant with RFC 1952. This implementation allows seeking in the compressed file. In normal gzip files that can only be achieved by decompressing from the start and discarding all data until the selected offset. This gzip implementation works around this by creating a special metadata file that maps uncompressed blocks to compressed blocks allowing it to only read the compressed blocks required.

A seekable stream is a valid Zstandard stream made from one or more compressed frames followed by a final skippable frame containing a seek table. Standard Zstandard decoders can read the stream from the beginning, while Reader uses the seek table to serve Read, ReadAt, and Seek calls by uncompressed byte offset and exposes the parsed metadata through Reader.SeekTable.

The package accepts small encoder and decoder interfaces and is tested with github.com/klauspost/compress/zstd.

This package implements a functionality for pristinely disassembling a tar archive, and stashing needed raw bytes and offsets to reassemble a validating original archive.

lz4 provides a streaming interface to LZ4 data streams as well as low level compress and uncompress functions for LZ4 data blocks. The implementation is based on the reference C one.

This package implements reader/writer library eStargz - a lazily-pullable image format.

This packages provides a seekable ZSTD compression format implemented in Golang. It is a random access reader (using uncompressed file offsets) for ZSTD-compressed streams. This can be used for creating transparent compression layers. Coupled with Content Defined Chunking (CDC) it can also be used as a robust de-duplication layer. It is an alternative fork of https://github.com/SaveTheRbtz/zstd-seekable-format-go.

This package provides an implementation of the LZO1X decompression algorithm in Go. The implementation is derived from the Linux kernel documentation for the LZO stream format and the implementation from lzokay project (MIT licensed). It includes a Reader for streaming decompressed data and a standalone Decompress function for use with byte slices.

Package extract allows to extract archives in zip,tar.gz or tar.bz2 formats easily.

This package implements a native XZ decompression in Golang.

Package archive provides helper functions for dealing with archive files.

go-rpmutils is a Golang library for parsing RPM file archives. It's a slimmed version of go-rpmutils.

This package defines basic interfaces to handle tar files. It is similar to fs.FS, but for tar files.

MinLZ is a LZ77-type compressor with a fixed byte-aligned encoding, in the similar class to Snappy and LZ4.

Package sevenzip provides read access to 7-zip archives inspired by std archive/zip. It is implemented in pure Go without external libraries or binaries needed.

This package provides readers and writers for CPIO archives. Currently, only the SVR4 (New ASCII) format is supported, both with and without checksums.
