About

A robust Go library for generating, parsing, and validating JSON Web Tokens (JWT) to enable secure authentication and authorization.

Go implementation of JSON Web Tokens (JWT).

Primary Use Case

This tool is primarily used by Go developers to implement authentication systems that rely on JWTs for secure token-based identity verification. It facilitates the creation, signing, and validation of JWTs in applications requiring secure access control and identity management.

Key Features

Full support for creating, parsing, signing, and validating JWTs
Supports multiple signing algorithms including HMAC SHA, RSA, RSA-PSS, and ECDSA
Backward compatibility with previous versions and upstream jwt-go library
Go module support for modern dependency management
Security best practices enforced, including algorithm validation
Maintained actively by a dedicated open source team
Aligned with Go's version release policy to ensure security
Extensible hooks for adding custom signing algorithms

Installation

Install Go from https://go.dev/doc/install
Run `go get -u github.com/golang-jwt/jwt/v5` to add the jwt package to your Go project
Import the package in your Go code using `import "github.com/golang-jwt/jwt/v5"`

Usage

>_ go get -u github.com/golang-jwt/jwt/v5

Installs the jwt-go library as a dependency in your Go project

>_ import "github.com/golang-jwt/jwt/v5"

Imports the jwt package into your Go source code

Usage Insights

Integrate with CI/CD pipelines to automate secure token generation and validation, reducing human error.
Use as a foundational component in building zero-trust authentication systems leveraging JWT claims.
Combine with runtime application self-protection (RASP) tools to detect anomalous token usage patterns.
Leverage extensible hooks to implement custom signing algorithms tailored to organizational cryptographic policies.
Employ in purple team exercises to simulate token-based attack vectors and improve detection and response capabilities.
