Examples with Algorithm com.nimbusds.jose.Algorithm used on opensource projects

Example 1 with Algorithm

use of com.nimbusds.jose.Algorithm in project spring-security by spring-projects.

Example 2 with Algorithm

use of com.nimbusds.jose.Algorithm in project ddf by codice.

the class OidcTokenValidator method validateAccessTokenSignature.

 * @param accessToken - the token to validate
 * @param idToken - the corresponding ID token or null if one is not available. If an ID token is
 *     provided, the signature algorithm in the ID token is used. Otherwise the Algorithm provided
 *     in the header of the access token is used.
 * @param resourceRetriever - resource retriever
 * @param metadata - OIDC metadata
