OpenID Authorization Code

class oauthlib.openid.connect.core.grant_types.AuthorizationCodeGrant(request_validator=None, **kwargs)[source]
add_id_token(token, token_handler, request)[source]

Construct an initial version of id_token, and let the request_validator sign or encrypt it.

The authorization_code version of this method is used to retrieve the nonce accordingly to the code storage.

id_token_hash(value, hashfunc=<built-in function openssl_sha256>)

Its value is the base64url encoding of the left-most half of the hash of the octets of the ASCII representation of the access_token value, where the hash algorithm used is the hash algorithm used in the alg Header Parameter of the ID Token’s JOSE Header.

For instance, if the alg is RS256, hash the access_token value with SHA-256, then take the left-most 128 bits and base64url-encode them. For instance, if the alg is HS512, hash the code value with SHA-512, then take the left-most 256 bits and base64url-encode them. The c_hash value is a case-sensitive string.

Example of hash from OIDC specification (bound to a JWS using RS256):

code: Qcb0Orv1zh30vL1MPRsbm-diHiMwcLyZvn1arpZv-Jxf_11jnpEX3Tgfvk

c_hash: LDktKdoQak3Pk0cnXxCltA


Perform OpenID Connect specific authorization request validation.

OPTIONAL. String value used to associate a Client session with an ID Token, and to mitigate replay attacks. The value is passed through unmodified from the Authentication Request to the ID Token. Sufficient entropy MUST be present in the nonce values used to prevent attackers from guessing values

OPTIONAL. ASCII string value that specifies how the Authorization Server displays the authentication and consent user interface pages to the End-User. The defined values are:

page - The Authorization Server SHOULD display the authentication and consent UI consistent with a full User Agent page view. If the display parameter is not specified, this is the default display mode.

popup - The Authorization Server SHOULD display the authentication and consent UI consistent with a popup User Agent window. The popup User Agent window should be of an appropriate size for a login-focused dialog and should not obscure the entire window that it is popping up over.

touch - The Authorization Server SHOULD display the authentication and consent UI consistent with a device that leverages a touch interface.

wap - The Authorization Server SHOULD display the authentication and consent UI consistent with a “feature phone” type display.

The Authorization Server MAY also attempt to detect the capabilities of the User Agent and present an appropriate display.


OPTIONAL. Space delimited, case sensitive list of ASCII string values that specifies whether the Authorization Server prompts the End-User for reauthentication and consent. The defined values are:

none - The Authorization Server MUST NOT display any authentication or consent user interface pages. An error is returned if an End-User is not already authenticated or the Client does not have pre-configured consent for the requested Claims or does not fulfill other conditions for processing the request. The error code will typically be login_required, interaction_required, or another code defined in Section This can be used as a method to check for existing authentication and/or consent.

login - The Authorization Server SHOULD prompt the End-User for reauthentication. If it cannot reauthenticate the End-User, it MUST return an error, typically login_required.

consent - The Authorization Server SHOULD prompt the End-User for consent before returning information to the Client. If it cannot obtain consent, it MUST return an error, typically consent_required.

select_account - The Authorization Server SHOULD prompt the End-User to select a user account. This enables an End-User who has multiple accounts at the Authorization Server to select amongst the multiple accounts that they might have current sessions for. If it cannot obtain an account selection choice made by the End-User, it MUST return an error, typically account_selection_required.

The prompt parameter can be used by the Client to make sure that the End-User is still present for the current session or to bring attention to the request. If this parameter contains none with any other value, an error is returned.

OPTIONAL. Maximum Authentication Age. Specifies the allowable elapsed time in seconds since the last time the End-User was actively authenticated by the OP. If the elapsed time is greater than this value, the OP MUST attempt to actively re-authenticate the End-User. (The max_age request parameter corresponds to the OpenID 2.0 PAPE [OpenID.PAPE] max_auth_age request parameter.) When max_age is used, the ID Token returned MUST include an auth_time Claim Value.
OPTIONAL. End-User’s preferred languages and scripts for the user interface, represented as a space-separated list of BCP47 [RFC5646] language tag values, ordered by preference. For instance, the value “fr-CA fr en” represents a preference for French as spoken in Canada, then French (without a region designation), followed by English (without a region designation). An error SHOULD NOT result if some or all of the requested locales are not supported by the OpenID Provider.
OPTIONAL. ID Token previously issued by the Authorization Server being passed as a hint about the End-User’s current or past authenticated session with the Client. If the End-User identified by the ID Token is logged in or is logged in by the request, then the Authorization Server returns a positive response; otherwise, it SHOULD return an error, such as login_required. When possible, an id_token_hint SHOULD be present when prompt=none is used and an invalid_request error MAY be returned if it is not; however, the server SHOULD respond successfully when possible, even if it is not present. The Authorization Server need not be listed as an audience of the ID Token when it is used as an id_token_hint value. If the ID Token received by the RP from the OP is encrypted, to use it as an id_token_hint, the Client MUST decrypt the signed ID Token contained within the encrypted ID Token. The Client MAY re-encrypt the signed ID token to the Authentication Server using a key that enables the server to decrypt the ID Token, and use the re-encrypted ID token as the id_token_hint value.
OPTIONAL. Hint to the Authorization Server about the login identifier the End-User might use to log in (if necessary). This hint can be used by an RP if it first asks the End-User for their e-mail address (or other identifier) and then wants to pass that value as a hint to the discovered authorization service. It is RECOMMENDED that the hint value match the value used for discovery. This value MAY also be a phone number in the format specified for the phone_number Claim. The use of this parameter is left to the OP’s discretion.
OPTIONAL. Requested Authentication Context Class Reference values. Space-separated string that specifies the acr values that the Authorization Server is being requested to use for processing this Authentication Request, with the values appearing in order of preference. The Authentication Context Class satisfied by the authentication performed is returned as the acr Claim Value, as specified in Section 2. The acr Claim is requested as a Voluntary Claim by this parameter.

Validates the OpenID Connect authorization request parameters.

Returns:(list of scopes, dict of request info)
