Request_object_signing_alg_values_supported is a OPTIONAL Openid-configuration JSONArray containing a list of the JSON Web Signature signing algorithms (alg values) supported by the OpenID Connect Identity Provider (IDP) for Request Objects, which are described in Section 6.1 of OpenID Connect Core 1.0.

These algorithms are used both when the Request Object is passed by value (using the request parameter) and when it is passed by reference (using the request_uri parameter). Servers SHOULD support none and RS256.
