 # SAP IAS openid-commandline-client

This project provides a command line interface (CLI) to generate OpenID (OIDC) Tokens from an OIDC complaint serverr, mainly created to test new features like PKCE and Public Client support or Private Key JWT. Mainly for IAS compliance tests. However, any other OIDC provider can be used to get tokens.

The execution will open a port on you localhost machine. Please ensure that this port is usable. In addition, you need to specify the redirect_uri in your OIDC server,

e.g. http://localhost:8080/callback. If you set port 9002, expect redirect_uri http://localhost:9002/callback

### How to build the project

Use the go tool chain to build the binary.

```text

go build cmd/openid-client.go

```

On an OS with make environment, simply execute

```text

make

```

### How to test

```text

./openid-client -h

Usage: openid-client

       This is a CLI to generate tokens from an OpenID Connect (OIDC) complaint server. Create a service provider/application in the OIDC server with call back url:

       http://localhost:/callback and set below flags to get an ID token

Flags:

      -issuer           IAS. Default is https://.accounts.ondemand.com; XSUAA Default is: https://uaa.cf.eu10.hana.ondemand.com/oauth/token

      -client_id        OIDC client ID. This is a mandatory flag.

      -client_secret    OIDC client secret. This is an optional flag and only needed for confidential clients.

      -client_tls       P12 file for client mTLS authentication. This is an optional flag and only needed for confidential clients as replacement for client_secret.

      -client_jwt       P12 file for private_key_jwt authentication. This is an optional flag and only needed for confidential clients as replacement for client_secret.

      -client_jwt_key   Private Key in PEM for private_key_jwt authentication. Use this parameter together with -client_jwt_kid. Replaces -client_jwt and -pin.

      -client_jwt_kid   Key ID for private_key_jwt authentication. Use this parameter together with -client_jwt_key. Replaces -client_jwt and -pin, use value or path to X509 certificate.

      -client_jwt_x5t   X5T Header for private_key_jwt authentication. Use this parameter together with -client_jwt_key. Replaces -client_jwt and -pin, use value or path to X509 certificate.

      -scope            OIDC scope parameter. This is an optional flag, default is openid. If you set none, the parameter scope will be omitted in request.

      -refresh          Bool flag. Default false. If true, call refresh flow for the received id_token.

      -idp_token        Bool flag. Default false. If true, call the OIDC IdP token exchange endpoint (IAS specific only) and return the response.

      -idp_scope        OIDC scope parameter. Default no scope is set. If you set the parameter idp_scope, it is set in IdP token exchange endpoint (IAS specific only).

      -refresh_expiry   Value in seconds. Optional parameter to reduce Refresh Token Lifetime.

      -token_format     Format for access_token. Possible values are opaque and jwt. Optional parameter, default: opaque

      -cmd              Single command to be executed. Supported commands currently: jwks, client_credentials, password

      -pin              PIN to P12/PKCS12 file using -client_tls or -client_jwt

      -port             Callback port. Open on localhost a port to retrieve the authorization code. Optional parameter, default: 8080

      -username         User name for command password grant required, else optional.

      -password         User password for command password grant required, else optional.
