merged dynamic client registration OAuth 2.0 & OIDC.md

name	OAuth 2.0 https://www.rfc-editor.org/rfc/rfc7591	OIDC https://openid.net/specs/openid-connect-registration-1_0.html
redirect_uris	Array of redirection URI strings for use in redirect-based flows such as the authorization code and implicit flows. As required by Section 2 of OAuth 2.0 [RFC6749], clients using flows with redirection MUST register their redirection URI values. Authorization servers that support dynamic registration for redirect-based flows MUST implement support for this metadata value.	REQUIRED. Array of Redirection URI values used by the Client. One of these registered Redirection URI values MUST exactly match the redirect_uri parameter value used in each Authorization Request, with the matching performed as described in Section 6.2.1 of [RFC3986] (Simple String Comparison).
token_endpoint_auth_method	String indicator of the requested authentication method for the token endpoint. Values defined by this specification are: * "none": The client is a public client as defined in OAuth 2.0, Section 2.1, and does not have a client secret. * "client_secret_post": The client uses the HTTP POST parameters as defined in OAuth 2.0, Section 2.3.1. * "client_secret_basic": The client uses HTTP Basic as defined in OAuth 2.0, Section 2.3.1. Additional values can be defined via the IANA "OAuth Token Endpoint Authentication Methods" registry established in Section 4.2. Absolute URIs can also be used as values for this parameter without being registered. If unspecified or omitted, the default is "client_secret_basic", denoting the HTTP Basic authentication scheme as specified in Section 2.3.1 of OAuth 2.0.	OPTIONAL. JSON array containing a list of the OAuth 2.0 response_type values that the Client is declaring that it will restrict itself to using. If omitted, the default is that the Client will use only the code Response Type.
grant_types	Array of OAuth 2.0 grant type strings that the client can use at the token endpoint. These grant types are defined as follows: * "authorization_code": The authorization code grant type defined in OAuth 2.0, Section 4.1. * "implicit": The implicit grant type defined in OAuth 2.0, Section 4.2. * "password": The resource owner password credentials grant type defined in OAuth 2.0, Section 4.3. * "client_credentials": The client credentials grant type defined in OAuth 2.0, Section 4.4. * "refresh_token": The refresh token grant type defined in OAuth 2.0, Section 6. * "urn:ietf:params:oauth:grant-type:jwt-bearer": The JWT Bearer Token Grant Type defined in OAuth JWT Bearer Token Profiles [RFC7523]. * "urn:ietf:params:oauth:grant-type:saml2-bearer": The SAML 2.0 Bearer Assertion Grant defined in OAuth SAML 2 Bearer Token Profiles [RFC7522]. If the token endpoint is used in the grant type, the value of this parameter MUST be the same as the value of the "grant_type" parameter passed to the token endpoint defined in the grant type definition. Authorization servers MAY allow for other values as defined in the grant type extension process described in OAuth 2.0, Section 4.5. If omitted, the default behavior is that the client will use only the "authorization_code" Grant Type.	OPTIONAL. JSON array containing a list of the OAuth 2.0 Grant Types that the Client is declaring that it will restrict itself to using. The Grant Type values used by OpenID Connect are: authorization_code: The Authorization Code Grant Type described in OAuth 2.0 Section 4.1. implicit: The Implicit Grant Type described in OAuth 2.0 Section 4.2. refresh_token: The Refresh Token Grant Type described in OAuth 2.0 Section 6. The following table lists the correspondence between response_type values that the Client will use and grant_type values that MUST be included in the registered grant_types list: code: authorization_code id_token: implicit token id_token: implicit code id_token: authorization_code, implicit code token: authorization_code, implicit code token id_token: authorization_code, implicit If omitted, the default is that the Client will use only the authorization_code Grant Type.
application_type		OPTIONAL. Kind of the application. The default, if omitted, is web. The defined values are native or web. Web Clients using the OAuth Implicit Grant Type MUST only register URLs using the https scheme as redirect_uris; they MUST NOT use localhost as the hostname. Native Clients MUST only register redirect_uris using custom URI schemes or URLs using the http: scheme with localhost as the hostname. Authorization Servers MAY place additional constraints on Native Clients. Authorization Servers MAY reject Redirection URI values using the http scheme, other than the localhost case for Native Clients. The Authorization Server MUST verify that all the registered redirect_uris conform to these constraints. This prevents sharing a Client ID across different types of Clients.
response_types	Array of the OAuth 2.0 response type strings that the client can use at the authorization endpoint. These response types are defined as follows: * "code": The authorization code response type defined in OAuth 2.0, Section 4.1. * "token": The implicit response type defined in OAuth 2.0, Section 4.2. If the authorization endpoint is used by the grant type, the value of this parameter MUST be the same as the value of the "response_type" parameter passed to the authorization endpoint defined in the grant type definition. Authorization servers MAY allow for other values as defined in the grant type extension process is described in OAuth 2.0, Section 4.5. If omitted, the default is that the client will use only the "code" response type.
client_name	Human-readable string name of the client to be presented to the end-user during authorization. If omitted, the authorization server MAY display the raw "client_id" value to the end-user instead. It is RECOMMENDED that clients always send this field. The value of this field MAY be internationalized, as described in Section 2.2.	OPTIONAL. Name of the Client to be presented to the End-User. If desired, representation of this Claim in different languages and scripts is represented as described in Section 2.1.
client_uri	URL string of a web page providing information about the client. If present, the server SHOULD display this URL to the end-user in a clickable fashion. It is RECOMMENDED that clients always send this field. The value of this field MUST point to a valid web page. The value of this field MAY be internationalized, as described in Section 2.2.	OPTIONAL. URL of the home page of the Client. The value of this field MUST point to a valid Web page. If present, the server SHOULD display this URL to the End-User in a followable fashion. If desired, representation of this Claim in different languages and scripts is represented as described in Section 2.1.
logo_uri	URL string that references a logo for the client. If present, the server SHOULD display this image to the end-user during approval. The value of this field MUST point to a valid image file. The value of this field MAY be internationalized, as described in Section 2.2.	OPTIONAL. URL that references a logo for the Client application. If present, the server SHOULD display this image to the End-User during approval. The value of this field MUST point to a valid image file. If desired, representation of this Claim in different languages and scripts is represented as described in Section 2.1.
scope	String containing a space-separated list of scope values (as described in Section 3.3 of OAuth 2.0 [RFC6749]) that the client can use when requesting access tokens. The semantics of values in this list are service specific. If omitted, an authorization server MAY register a client with a default set of scopes.
contacts	Array of strings representing ways to contact people responsible for this client, typically email addresses. The authorization server MAY make these contact addresses available to end-users for support requests for the client. See Section 6 for information on Privacy Considerations.	OPTIONAL. Array of e-mail addresses of people responsible for this Client. This might be used by some providers to enable a Web user interface to modify the Client information.
tos_uri	URL string that points to a human-readable terms of service document for the client that describes a contractual relationship between the end-user and the client that the end-user accepts when authorizing the client. The authorization server SHOULD display this URL to the end-user if it is provided. The value of this field MUST point to a valid web page. The value of this field MAY be internationalized, as described in Section 2.2.	OPTIONAL. URL that the Relying Party Client provides to the End-User to read about the Relying Party's terms of service. The value of this field MUST point to a valid web page. The OpenID Provider SHOULD display this URL to the End-User if it is given. If desired, representation of this Claim in different languages and scripts is represented as described in Section 2.1.
policy_uri	URL string that points to a human-readable privacy policy document that describes how the deployment organization collects, uses, retains, and discloses personal data. The authorization server SHOULD display this URL to the end-user if it is provided. The value of this field MUST point to a valid web page. The value of this field MAY be internationalized, as described in Section 2.2.	OPTIONAL. URL that the Relying Party Client provides to the End-User to read about the how the profile data will be used. The value of this field MUST point to a valid web page. The OpenID Provider SHOULD display this URL to the End-User if it is given. If desired, representation of this Claim in different languages and scripts is represented as described in Section 2.1.
jwks_uri	URL string referencing the client's JSON Web Key (JWK) Set [RFC7517] document, which contains the client's public keys. The value of this field MUST point to a valid JWK Set document. These keys can be used by higher-level protocols that use signing or encryption. For instance, these keys might be used by some applications for validating signed requests made to the token endpoint when using JWTs for client authentication [RFC7523]. Use of this parameter is preferred over the "jwks" parameter, as it allows for easier key rotation. The "jwks_uri" and "jwks" parameters MUST NOT both be present in the same request or response.	OPTIONAL. URL for the Client's JSON Web Key Set [JWK] document. If the Client signs requests to the Server, it contains the signing key(s) the Server uses to validate signatures from the Client. The JWK Set MAY also contain the Client's encryption keys(s), which are used by the Server to encrypt responses to the Client. When both signing and encryption keys are made available, a use (Key Use) parameter value is REQUIRED for all keys in the referenced JWK Set to indicate each key's intended usage. Although some algorithms allow the same key to be used for both signatures and encryption, doing so is NOT RECOMMENDED, as it is less secure. The JWK x5c parameter MAY be used to provide X.509 representations of keys provided. When used, the bare key values MUST still be present and MUST match those in the certificate.
jwks	Client's JSON Web Key Set [RFC7517] document value, which contains the client's public keys. The value of this field MUST be a JSON object containing a valid JWK Set. These keys can be used by higher-level protocols that use signing or encryption. This parameter is intended to be used by clients that cannot use the "jwks_uri" parameter, such as native clients that cannot host public URLs. The "jwks_uri" and "jwks" parameters MUST NOT both be present in the same request or response.	OPTIONAL. Client's JSON Web Key Set [JWK] document, passed by value. The semantics of the jwks parameter are the same as the jwks_uri parameter, other than that the JWK Set is passed by value, rather than by reference. This parameter is intended only to be used by Clients that, for some reason, are unable to use the jwks_uri parameter, for instance, by native applications that might not have a location to host the contents of the JWK Set. If a Client can use jwks_uri, it MUST NOT use jwks. One significant downside of jwks is that it does not enable key rotation (which jwks_uri does, as described in Section 10 of OpenID Connect Core 1.0 [OpenID.Core]). The jwks_uri and jwks parameters MUST NOT be used together.
software_id	A unique identifier string (e.g., a Universally Unique Identifier (UUID)) assigned by the client developer or software publisher used by registration endpoints to identify the client software to be dynamically registered. Unlike "client_id", which is issued by the authorization server and SHOULD vary between instances, the "software_id" SHOULD remain the same for all instances of the client software. The "software_id" SHOULD remain the same across multiple updates or versions of the same piece of software. The value of this field is not intended to be human readable and is usually opaque to the client and authorization server.
software_version	A version identifier string for the client software identified by "software_id". The value of the "software_version" SHOULD change on any update to the client software identified by the same "software_id". The value of this field is intended to be compared using string equality matching and no other comparison semantics are defined by this specification. The value of this field is outside the scope of this specification, but it is not intended to be human readable and is usually opaque to the client and authorization server. The definition of what constitutes an update to client software that would trigger a change to this value is specific to the software itself and is outside the scope of this specification.
sector_identifier_uri		OPTIONAL. URL using the https scheme to be used in calculating Pseudonymous Identifiers by the OP. The URL references a file with a single JSON array of redirect_uri values. Please see Section 5. Providers that use pairwise sub (subject) values SHOULD utilize the sector_identifier_uri value provided in the Subject Identifier calculation for pairwise identifiers.
subject_type		OPTIONAL. subject_type requested for responses to this Client. The subject_types_supported Discovery parameter contains a list of the supported subject_type values for this server. Valid types include pairwise and public.
id_token_signed_response_alg		OPTIONAL. JWS alg algorithm [JWA] REQUIRED for signing the ID Token issued to this Client. The value none MUST NOT be used as the ID Token alg value unless the Client uses only Response Types that return no ID Token from the Authorization Endpoint (such as when only using the Authorization Code Flow). The default, if omitted, is RS256. The public key for validating the signature is provided by retrieving the JWK Set referenced by the jwks_uri element from OpenID Connect Discovery 1.0 [OpenID.Discovery].
id_token_encrypted_response_alg		OPTIONAL. JWE alg algorithm [JWA] REQUIRED for encrypting the ID Token issued to this Client. If this is requested, the response will be signed then encrypted, with the result being a Nested JWT, as defined in [JWT]. The default, if omitted, is that no encryption is performed.
id_token_encrypted_response_enc		OPTIONAL. JWE enc algorithm [JWA] REQUIRED for encrypting the ID Token issued to this Client. If id_token_encrypted_response_alg is specified, the default for this value is A128CBC-HS256. When id_token_encrypted_response_enc is included, id_token_encrypted_response_alg MUST also be provided.
userinfo_signed_response_alg		OPTIONAL. JWS alg algorithm [JWA] REQUIRED for signing UserInfo Responses. If this is specified, the response will be JWT [JWT] serialized, and signed using JWS. The default, if omitted, is for the UserInfo Response to return the Claims as a UTF-8 encoded JSON object using the application/json content-type.
userinfo_encrypted_response_alg		OPTIONAL. JWE [JWE] alg algorithm [JWA] REQUIRED for encrypting UserInfo Responses. If both signing and encryption are requested, the response will be signed then encrypted, with the result being a Nested JWT, as defined in [JWT]. The default, if omitted, is that no encryption is performed.
userinfo_encrypted_response_enc		OPTIONAL. JWE enc algorithm [JWA] REQUIRED for encrypting UserInfo Responses. If userinfo_encrypted_response_alg is specified, the default for this value is A128CBC-HS256. When userinfo_encrypted_response_enc is included, userinfo_encrypted_response_alg MUST also be provided.
request_object_signing_alg		OPTIONAL. JWS [JWS] alg algorithm [JWA] that MUST be used for signing Request Objects sent to the OP. All Request Objects from this Client MUST be rejected, if not signed with this algorithm. Request Objects are described in Section 6.1 of OpenID Connect Core 1.0 [OpenID.Core]. This algorithm MUST be 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 RS256. The value none MAY be used. The default, if omitted, is that any algorithm supported by the OP and the RP MAY be used.
request_object_encryption_alg		OPTIONAL. JWE [JWE] alg algorithm [JWA] the RP is declaring that it may use for encrypting Request Objects sent to the OP. This parameter SHOULD be included when symmetric encryption will be used, since this signals to the OP that a client_secret value needs to be returned from which the symmetric key will be derived, that might not otherwise be returned. The RP MAY still use other supported encryption algorithms or send unencrypted Request Objects, even when this parameter is present. If both signing and encryption are requested, the Request Object will be signed then encrypted, with the result being a Nested JWT, as defined in [JWT]. The default, if omitted, is that the RP is not declaring whether it might encrypt any Request Objects.
request_object_encryption_enc		OPTIONAL. JWE enc algorithm [JWA] the RP is declaring that it may use for encrypting Request Objects sent to the OP. If request_object_encryption_alg is specified, the default for this value is A128CBC-HS256. When request_object_encryption_enc is included, request_object_encryption_alg MUST also be provided.
token_endpoint_auth_method		OPTIONAL. Requested Client Authentication method for the Token Endpoint. The options are client_secret_post, client_secret_basic, client_secret_jwt, private_key_jwt, and none, as described in Section 9 of OpenID Connect Core 1.0 [OpenID.Core]. Other authentication methods MAY be defined by extensions. If omitted, the default is client_secret_basic -- the HTTP Basic Authentication Scheme specified in Section 2.3.1 of OAuth 2.0 [RFC6749].
token_endpoint_auth_signing_alg		OPTIONAL. JWS [JWS] alg algorithm [JWA] that MUST be used for signing the JWT [JWT] used to authenticate the Client at the Token Endpoint for the private_key_jwt and client_secret_jwt authentication methods. All Token Requests using these authentication methods from this Client MUST be rejected, if the JWT is not signed with this algorithm. Servers SHOULD support RS256. The value none MUST NOT be used. The default, if omitted, is that any algorithm supported by the OP and the RP MAY be used.
default_max_age		OPTIONAL. Default Maximum Authentication Age. Specifies that the End-User MUST be actively authenticated if the End-User was authenticated longer ago than the specified number of seconds. The max_age request parameter overrides this default value. If omitted, no default Maximum Authentication Age is specified.
require_auth_time		OPTIONAL. Boolean value specifying whether the auth_time Claim in the ID Token is REQUIRED. It is REQUIRED when the value is true. (If this is false, the auth_time Claim can still be dynamically requested as an individual Claim for the ID Token using the claims request parameter described in Section 5.5.1 of OpenID Connect Core 1.0 [OpenID.Core].) If omitted, the default value is false.
default_acr_values		OPTIONAL. Default requested Authentication Context Class Reference values. Array of strings that specifies the default acr values that the OP is being requested to use for processing requests from this Client, with the values appearing in order of preference. The Authentication Context Class satisfied by the authentication performed is returned as the acr Claim Value in the issued ID Token. The acr Claim is requested as a Voluntary Claim by this parameter. The acr_values_supported discovery element contains a list of the supported acr values supported by this server. Values specified in the acr_values request parameter or an individual acr Claim request override these default values.
initiate_login_uri		OPTIONAL. URI using the https scheme that a third party can use to initiate a login by the RP, as specified in Section 4 of OpenID Connect Core 1.0 [OpenID.Core]. The URI MUST accept requests via both GET and POST. The Client MUST understand the login_hint and iss parameters and SHOULD support the target_link_uri parameter.
request_uris		OPTIONAL. Array of request_uri values that are pre-registered by the RP for use at the OP. Servers MAY cache the contents of the files referenced by these URIs and not retrieve them at the time they are used in a request. OPs can require that request_uri values used be pre-registered with the require_request_uri_registration discovery parameter. If the contents of the request file could ever change, these URI values SHOULD include the base64url encoded SHA-256 hash value of the file contents referenced by the URI as the value of the URI fragment. If the fragment value used for a URI changes, that signals the server that its cached value for that URI with the old fragment value is no longer valid.
