Package archive provides helper functions for dealing with archive files.

Package compress is a collection of compression libraries implementing Golang modules:

brotli

Implements the Brotli format, described in RFC 7932.

bzip2

Implements the BZip2 compressed data format.

flate

Implements the DEFLATE format, described in RFC 1951.

xflate

Implements the XFLATE format, an random-access extension to DEFLATE.

This package provides a Go implementation of the Snappy compression format.

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 provides a support of reading and writing of xz compressed streams. It includes also a gxz command for compressing and decompressing data. The package is completely written in Go and doesn't have any dependency on any C code.

This package provides a Go wrapper to zstd C library.

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 an enhanced version of the compress/lzw library included in the stdlib, and supports GIF, TIFF and PDF.

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 is a brotli compressor and decompressor implemented in Go. It was translated from the reference implementation (https://github.com/google/brotli) with the c2go tool at https://github.com/andybalholm/c2go.

Package archiver facilitates convenient, cross-platform, high-level archival and compression operations for a variety of formats and compression algorithms.

Features:

• stream-oriented APIs

• automatically identify archive and compression formats

• traverse directories, archive files, and any other file uniformly as io/fs file systems

• compress and decompress files

• walk or traverse into archive files

• extract only specific files from archives

• insert (append) into .tar and .zip archives

• read from password-protected 7-Zip files

• numerous archive and compression formats supported

• extensible (add more formats just by registering them)

• cross-platform, static binary

• pure Golang (no cgo)

• multithreaded Gzip

• adjust compression levels

• automatically add compressed files to zip archives without re-compressing

• open password-protected rar archives

• .rar (read-only)

• .7z (read-only)

This package provides an command line interface (CLI) tool.

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 a native XZ decompression in Golang.

pcg is a random number generator that uses Permuted Congruential Generator (PCG) algorithm.

This package provides qtls, a QUIC-capable variant of the Go standard library's TLS 1.3 implementation.

This package implements a hash/displace minimal perfect hash function.

This package provides a Go library for the Concise Binary Object Representation (CBOR) Object Signing and Encryption (COSE) specification.

This package provides a hashing function.

noise implements the Noise protocol framework. Noise is a low-level framework for building crypto protocols. Noise protocols support mutual and optional authentication, identity hiding, forward secrecy, zero round-trip encryption, and other advanced features.

This package implements file encryption according to the https://age-encryption.org/v1 specification. It features small explicit keys, no configuration options, and Unix-style composability. This package provides a command line interface (CLI) tools.

Package crypt is a implementation of crypt(3) by golang, originated from https://code.google.com/p/go-crypt.

This package implements a functionality to convert keys between the PEM and JWK file formats.

Package ssh wraps the crypto/ssh package with a higher-level API for building SSH servers. The goal of the API was to make it as simple as using net/http, so the API is very similar.
