OpenID Connect Debugger

A simple Debugger for OpenID Connect IdPs.

Why

You ever needed to quickly check if the IdP works? What the user endpoint returns? Get the token?
Then this is a simple command line utility for that use case.

There are some online tools for that but they either need a server or use cors. This tool is a simple go binary that just runs on your computer.

Usage

Run the binary. It will show the help. It will work something like that:

openidcheck -clientid test -endpoint https://idp.example.com -secret 1234 -verbosity 3

It will automatically use the well-known definition of the server.

Usage with Keycloak

For Keycloak you might need to specify the realm. Use it something like:

openidcheck -clientid test -endpoint https://idp.example.com/realms/yourRealm -secret 1234 -verbosity 3
