(Chilkat2-Python) Retrieve the Okta JSON Web Keys (JWK)

Demonstrates how to get the Okta web keys (JWK) that will be needed to locally validate an access token. This example is for the case where Okta is the identity platform for your App or API. (See https://developer.okta.com/docs/reference/api/oidc/#composing-your-base-url)

Note: This example uses the URL

https://dev-765951.okta.com/oauth2/${authServerId}/v1/authorize

If you have a developer account, you can use the default authorization server that was created along with your account, in which case the full URL looks like this:

https://dev-765951.okta.com/oauth2/default/v1/authorize

Also: You'll need to change "dev-765951" to use your own Okta domain.

For more information, see https://developer.okta.com/docs/reference/api/oidc/#keys
