This includes support for JSON Web Encryption, +JSON Web Signature, and JSON Web Token standards. + +## Overview + +The implementation follows the +[JSON Web Encryption](https://dx.doi.org/10.17487/RFC7516) (RFC 7516), +[JSON Web Signature](https://dx.doi.org/10.17487/RFC7515) (RFC 7515), and +[JSON Web Token](https://dx.doi.org/10.17487/RFC7519) (RFC 7519) specifications. +Tables of supported algorithms are shown below. The library supports both +the compact and JWS/JWE JSON Serialization formats, and has optional support for +multiple recipients. It also comes with a small command-line utility +([`jose-util`](https://pkg.go.dev/github.com/go-jose/go-jose/jose-util)) +for dealing with JOSE messages in a shell. + +**Note**: We use a forked version of the `encoding/json` package from the Go +standard library which uses case-sensitive matching for member names (instead +of [case-insensitive matching](https://www.ietf.org/mail-archive/web/json/current/msg03763.html)). +This is to avoid differences in interpretation of messages between go-jose and +libraries in other languages. + +### Versions + +The forthcoming Version 5 will be released with several breaking API changes, +and will require Golang's `encoding/json/v2`, which is currently requires +Go 1.25 built with GOEXPERIMENT=jsonv2. + +Version 4 is the current stable version: + + import "github.com/go-jose/go-jose/v4" + +It supports at least the current and previous Golang release. Currently it +requires Golang 1.24. + +Version 3 is only receiving critical security updates. Migration to Version 4 is recommended. + +Versions 1 and 2 are obsolete, but can be found in the old repository, [square/go-jose](https://github.com/square/go-jose). + +### Supported algorithms + +See below for a table of supported algorithms.
