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

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.

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

Features:

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

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.

Package imohash implements a fast, constant-time hash for files. It is based atop murmurhash3 and uses file size and sample data to construct the hash.

This package provides a Go implementation of JSON Web Tokens and supports the parsing and verification as well as the generation and signing of JSON Web Tokens. The currently supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.

Package pbkdf2 implements password-based key derivation using the PBKDF2 algorithm described in RFC 2898 and RFC 8018.

This package provides Abstract Syntax Notation One BER encoding and decoding in the Go language.

Shapeshifter-Transports is a set of Pluggable Transports implementing the Go API from the Pluggable Transports 2.0 specification. Each transport implements a different method of shapeshifting network traffic. The goal is for application traffic to be sent over the network in a shapeshifted form that bypasses network filtering, allowing the application to work on networks where it would otherwise be blocked or heavily throttled.

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

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

Package shuffle provides primitives for shuffling slices and user-defined collections.

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