public class ValidatePKCE
extends AbstractOIDCResponseAction

Action performs PKCE (https://oauth.net/2/pkce/) validation. If authentication request contains code_challenge parameter, token request when passing authorization code as grant must include code_verifier parameter. Profile configuration may used to force using PKCE, by default it is optional. Profile configuration may be used to allow plain PKCE, by default it is not allowed.
