## What it is
A Go library for creating, signing, parsing, and verifying JSON Web Tokens (JWTs) per RFC 7519. It is the community-maintained successor to dgrijalva/jwt-go, supporting HMAC, RSA, RSA-PSS, ECDSA, and EdDSA signing algorithms.

## Use cases
- issue and sign JWTs in a Go web service
- validate Bearer tokens for OAuth 2.0 authentication
- parse and verify JWT claims in middleware
- sign tokens with Ed25519 or ECDSA keys
- migrate from the deprecated dgrijalva/jwt-go library

## When to choose
- you need JWT support in a Go application
- you want a well-maintained, community-backed fork of jwt-go
- you need flexible signing algorithms including EdDSA
- you need strict token validation controls

## When to avoid
- you need full JOSE features like JWE encryption (this library only does JWS signing)
- you are not working in Go
- you need a complete identity provider or OAuth server rather than a token library

## Facets
- artifact type: library
- maturity: stable
- function: auth, cryptography, serialization, security
- domain: security, backend, developer-tools, apis
- platform: go, cross-platform
- tags: jwt, json-web-tokens, oauth2, bearer-tokens, ed25519, token-signing, token-validation, rfc7519
