This section describes the IS 5.4.0 support for various endpoints.

...

The JSON Web Key Set (JWKS) endpoint is a read-only endpoint

...

that returns the Identity Server's public key set in

...

the JWKS format. This contains the signing key(s) that the Relying Party (RP) uses to validate signatures from the Identity Server.

...

For more information on this endpoint, see the OpenID Connect Discovery specification.

Let's take a look at the endpoints used in WSO2 Identity Server (WSO2 IS):

For tenants

Info
By default, `<IS_HOST>` is `localhost.` However, if you are using a public IP, the respective IP address or domain needs to be specified. By default, `<IS_HTTPS_PORT>` has been set to 9443. However, if the port offset has been incremented by `n`, the default port value needs to be incremented by `n`.

Example: https://localhost:9443/

ID Token contains kid value

The header of the id_token contains a kid claim, which indicates the key that was used to sign the id_token. The same kid value is used in the jwks endpoint to validate the signature of the id_token.

Support to the “claims” Request Parameter

If the "claims" request parameter is used with authorization request with the value 'userinfo' and 'essential =true' the defined claim will be return from the user info endpoint ignoring the requested scope. But this claim should be a requested claim.

Eg : https://localhost:9443/oauth2/authorize?response_type=token&client_id=XXXXXXXX&redirect_uri=http://localhost:8080/playground2&nonce=rrr&claims=userinfo&essential=true&scope =openid

We support [1].

We support following request parameters as well

.

The WSO2 Identity Server is shipped with a signed ID Token. This is provided in order to address some security vulnerabilities in a typical production environment. This topic provides information about using this signed ID Token for signature verification.

Info
The portions of each token are separated by the full stop. To see the exact JSON values, do a Base64 decode for `<header>.<body>`.

If the unsigned ID token contains only 2 portions:
<header>.<body>

Validating the ID token signature

The following code segment is a simple Java program that can be used to validate the ID token signature against the default wso2carbon.jks public key in WSO2 products.

Property value	description
`kty`	The public key type.
`e`	The exponent value of the public key.
`use`	Implies how the key is being used. The value `sig` represents signature.
`kid`	The thumbprint of the certificate. This value is used to identify the key that needs to be used to verify the signature.
`alg`	The algorithm used to secure the JSON Web Signature.
`n`	The modulus value of the public key.

The endpoint URL for tenants

Endpoint URL

Copy the following URL to your browser: https://<IS_HOST>:<IS_PORT>/t/<TENANT_DOMAIN>/oauth2/jwks

Info
By default, `<IS_HOST>` is `localhost.` However, if you are using a public IP, the respective IP address or domain needs to be specified. By default, `<IS_HTTPS_PORT>` has been set to 9443. However, if the port offset has been incremented by `n`, the default port value needs to be incremented by `n`. Enter your tenant domain for `<TENANT_DOMAIN>`.

Example: https://localhost:9443/t/foo.com/oauth2/jwks
