spring-security-saml2를 사용하여 암호화된 주장을 사용하도록 서비스 공급자를 구성하는 방법은 무엇입니까?

나는 이 훌륭한 repovdenotaris/spring-boot-security-saml-sample을 가이드로 사용하고 있으며 다음을 포함하는 수신 SAML 메시지를 확인하고 해독하도록 설정하려고 합니다.EncryptedAssertion.

idP의 메타데이터는 XML에서 서명 및 암호화 키를 정의합니다.서비스 공급자에 설정되어 있습니다.

@Bean
public ExtendedMetadata extendedMetadata() {
    ExtendedMetadata extendedMetadata = new ExtendedMetadata();
    extendedMetadata.setIdpDiscoveryEnabled(false);
    extendedMetadata.setSignMetadata(false);
    extendedMetadata.setEcpEnabled(true);
    return extendedMetadata;
}

@Bean
@Qualifier("metadata")
public CachingMetadataManager metadata() throws MetadataProviderException {
    List<MetadataProvider> providers = new ArrayList<MetadataProvider>();
    
    try {
        ClasspathResource metadata = new ClasspathResource("/metadata/the-idp-metadata.xml");
        Timer timer = new Timer(true);
        ResourceBackedMetadataProvider provider = new ResourceBackedMetadataProvider(timer, metadata);
        provider.setParserPool(ParserPoolHolder.getPool());
        provider.initialize();
    
        ExtendedMetadataDelegate exMetadataDelegate = new ExtendedMetadataDelegate(provider, extendedMetadata());
        exMetadataDelegate.setMetadataTrustCheck(true);
        exMetadataDelegate.setMetadataRequireSignature(false);
        providers.add(exMetadataDelegate);
    }
    catch(ResourceException ex) {
        throw new MetadataProviderException(ex.getMessage(), ex);
    }
    
    CachingMetadataManager cmm = new CachingMetadataManager(providers);
    cmm.setRefreshCheckInterval(0);
    
    return cmm;
}

암호화된 어설션이 있는 SAML 메시지 샘플을 수동으로 보내면 다음 메시지와 함께 실패합니다.

여기서 메타데이터 구성을 읽었는데, idp가 어설션의 암호를 해독하기 위해 사용하는 서명 및 암호화 키를 구성할 수 있습니다(적어도 제가 가정하는 것은 그렇습니다).

그것이 서비스가 소비하도록 하는 올바른 방법입니까?EncryptedAssertions? 이 잘못된 메시지 벽을 계속 누르고 있지만 이 문제를 처리하는 방법을 명시적으로 설명하는 좋은 솔리드 자습서나 문서를 찾지 못했습니다.또한 솔루션이 다음에 있는지 여부를 확신할 수 없습니다.WebSSOProfileConsumerImpl수정해야 하는 수업?

어떤 도움이나 예를 들어주시면 감사하겠습니다.

일반적으로 SAML Tools(https://www.samltool.com/generic_sso_res.php), 에는 암호화된 어설션이 포함된 몇 가지 예제가 있습니다.

자동화된 테스트의 경우, 우리는 XML에 직접 서명하여 SAML 요청 및 응답을 즉시 생성하고 통합 테스트에서 애플리케이션에 제공하는 경향이 있습니다.
