• 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

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

Fastzip is an opinionated Zip archiver and extractor with a focus on speed. Features:

• archiving and extraction of files and directories can only occur within a specified directory

• permissions, ownership (uid, gid on linux/unix) and modification times are preserved

• buffers used for copying files are recycled to reduce allocations

• files are archived and extracted concurrently

• by default, github.com/klauspost/compress/flate library is used for compression and decompression

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 an additional command line interface tool to compress and decompress LZ4 files.

Fast implementation of base58 encoding on Golang. A trivial big.Int encoding benchmark results in 6 times faster encoding and 8 times faster decoding.

This package provides ShāngMì 4 cipher suites implementation (GM SM2/3/4).

Main functions:

• SM2 national secret elliptic curve algorithm library

• SM3 national secret hash algorithm library

• SM4 national secret block cipher algorithm library

GoPtLib is a library for writing Tor pluggable transports in Go.

This is a SIMD accelerated MD5 package, allowing up to either 8 (AVX2) or 16 (AVX512) independent MD5 sums to be calculated on a single CPU core.

md5-simd integrates a similar mechanism as described in minio/sha256-simd for making it easy for clients to take advantages of the parallel nature of the MD5 calculation. This will result in reduced overall CPU load.

This library is a JWT implementation that uses nkeys to digitally sign JWT tokens. Nkeys use Ed25519 to provide authentication of JWT claims.

PKI based identities for use in go-libp2p.

This package provides a hashing function.

This package provides a drop-in replacement of the Golang standard encoding/base64 library.
