README
OpenID Connect SDK (client and server) for Go
What Is It
This project is an easy-to-use client (RP) and server (OP) implementation for the OIDC (OpenID Connect) standard written for Go.
The RP is certified for the basic and config profile.
Whenever possible we tried to reuse / extend existing packages like OAuth2 for Go.
Basic Overview
The most important packages of the library:
/pkg
/client clients using the OP for retrieving, exchanging and verifying tokens
/rp definition and implementation of an OIDC Relying Party (client)
/rs definition and implementation of an OAuth Resource Server (API)
/op definition and implementation of an OIDC OpenID Provider (server)
/oidc definitions shared by clients and server
/example /api example of an api / resource server implementation using token introspection /app web app / RP demonstrating authorization code flow using various authentication methods (code, PKCE, JWT profile) /github example of the extended OAuth2 library, providing an HTTP client with a reuse token source /service demonstration of JWT Profile Authorization Grant /server example of an OpenID Provider implementation including some very basic login UI
How To Use It
Check the /example folder where example code for different scenarios is located.
# start oidc op server
# oidc discovery http://localhost:9998/.well-known/openid-configuration
go run github.com/zitadel/oidc/example/server
# start oidc web client
CLIENT_ID=web CLIENT_SECRET=secret ISSUER=http://localhost:9998 SCOPES="openid profile" PORT=9999 go run github.com/zitadel/oidc/example/client/app
- open http://localhost:9999/login in your browser
- you will be redirected to op server and the login UI
- login with user
test-userand passwordverysecure - the OP will redirect you to the client app, which displays the user info

Supported Go Versions
For security reasons, we only support and recommend the use of one of the latest two Go versions (:white_check_mark:).

Why another library
As of 2020 there are not a lot of OIDC library's in Go which can handle server and client implementations. ZITADEL is strongly committed to the general field of IAM (Identity and Access Management) and as such, we need solid frameworks to implement services.
Goals
Other Go OpenID Connect libraries
https://github.com/coreos/go-oidc
The go-oidc does only support RP and is not feasible to use as OP that's why we could not rely on go-oidc
We did not choose fosite because it implements OAuth 2.0 on its own and does not rely on the golang provided package. Nonetheless this is a great project.
