Examples with JOSE org.keycloak.jose.JOSE used on opensource projects

Example 1 with JOSE

use of org.keycloak.jose.JOSE in project keycloak by keycloak.

the class DefaultTokenManager method decodeClientJWT.

@Override
public <T> T decodeClientJWT(String jwt, ClientModel client, BiConsumer<JOSE, ClientModel> jwtValidator, Class<T> clazz) {
