Ironwood is a routing library with a net.PacketConn-compatible interface using ed25519.PublicKeys as addresses. Basically, you use it when you want to communicate with some other nodes in a network, but you can't guarantee that you can directly connect to every node in that network. It was written to test improvements to / replace the routing logic in Yggdrasil, but it may be useful for other network applications.

This package provides a library for calling C functions from Go without Cgo.

Featues:

• build for other platforms easily without a C compiler

• efficiently cache entirely Go builds

• using Cgo generates a C wrapper function for each C function called

• load symbols at runtime and use it as a plugin system

• call into other languages that are compiled into shared objects

• works even with CGO_ENABLED=1 so incremental porting is possible

Package netns allows ultra-simple network namespace handling. NsHandles can be retrieved and set. Note that the current namespace is thread local so actions that set and reset namespaces should use LockOSThread to make sure the namespace doesn't change due to a goroutine switch. It is best to close NsHandles when you are done with them. This can be accomplished via a `defer ns.Close()` on the handle. Changing namespaces requires elevated privileges, so in most cases this code needs to be run as root.

BunRouter is a fast HTTP router for Go with unique combination of features:

• middlewares allow to extract common operations from HTTP handlers into reusable functions

• error handling allows to further reduce the size of HTTP handlers by handling errors in middlewares

• routes priority enables meaningful matching priority for routing rules: first static nodes, then named nodes, lastly wildcard nodes

• net/http compatible API which means using minimal API without constructing huge wrappers that try to do everything: from serving static files to XML generation (for example, gin.Context or echo.Context)

Accelerate SHA256 computations in pure Go using AVX512 and AVX2 for Intel and ARM64 for ARM. On AVX512 it provides an up to 8x improvement (over 3 GB/s per core) in comparison to AVX2.

This package is designed as a replacement for crypto/sha256. For Intel CPUs it has two flavors for AVX512 and AVX2 (AVX/SSE are also supported). For ARM CPUs with the Cryptography Extensions, advantage is taken of the SHA2 instructions resulting in a massive performance improvement.

This package uses Golang assembly. The AVX512 version is based on the Intel's "multi-buffer crypto library for IPSec" whereas the other Intel implementations are described in "Fast SHA-256 Implementations on Intel Architecture Processors" by J. Guilford et al.

This source package is a collection of utilities intended to make it easier for Go programs to work with System Package Data Exchange files. It currently works with files conformant to versions 2.1, 2.2 and 2.3 of the SPDX specification and provides the following packages:

• spdx - in-memory data model for the sections of an SPDX document

• tagvalue - tag-value document reader and writer

• rdf - RDF document reader

• json - JSON document reader and writer

• yaml - YAML document reader and writer

• builder - builds empty SPDX document (with hashes) for directory contents

• idsearcher - searches for SPDX short-form IDs and builds an SPDX document

• licensediff - compares concluded licenses between files in two packages

• reporter - generates basic license count report from an SPDX document

• spdxlib - various utility functions for manipulating SPDX documents in memory

• utils - various utility functions that support the other tools-golang packages

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

• 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

Supported compression formats:
