## What it is
A comprehensive Go library implementing the full JOSE family of standards (JWA, JWE, JWK, JWS, JWT) for signing, verifying, encrypting, and decrypting tokens and messages. It offers a uniform API, JWK caching via an extension module, and post-quantum algorithm support including ML-KEM, ML-DSA, and HPKE.

## Use cases
- sign and verify JWTs in a Go service
- parse and validate OIDC ID tokens
- encrypt payloads with JWE
- fetch and cache JWKS keys from an identity provider
- sign messages with multiple signatures using JWS
- try post-quantum signing algorithms like ML-DSA

## When to choose
- you need complete JOSE coverage in Go, not just basic JWT handling
- you need JWS detached payloads, RFC 7797, or multi-recipient JWE
- you want a consistent, option-based API across all JWx operations
- you need post-quantum cryptography support

## When to avoid
- you only need minimal JWT signing and a smaller dependency suffices
- you are not using Go
- you cannot run Go 1.26+ or manage the GOEXPERIMENT=jsonv2 requirement on Go 1.26
- you need a batteries-included auth server rather than a token library

## Facets
- artifact type: library
