【中文标题】如何使用 spring-security-saml2 配置服务提供者以使用 EncryptedAssertions？【英文标题】：How to configure service provider with spring-security-saml2 to consume EncryptedAssertions? 【发布时间】：2019-08-27 14:09:41 【问题描述】：我正在使用这个优秀的 repo vdenotaris/spring-boot-security-saml-sample 作为指导，我正在尝试设置它来验证和解密包含EncryptedAssertion 的传入 SAML 消息。
idP 的元数据在 XML 中定义签名和加密密钥。这是在服务提供者中设置的。
@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;
当我手动向它发送具有加密断言的 SAML 消息样本时，它会失败并显示以下消息。

我在这里读到Metadata Configuration，您可以配置 idp 使用的签名和加密密钥，以便 解密 断言（至少这是我的假设）。
这是让服务使用EncryptedAssertions 的正确方法吗？我一直在点击这个无效的消息墙，但没有找到明确描述如何处理这个问题的好的可靠教程或文档。也不确定解决方案是否存在于我必须修改的WebSSOProfileConsumerImpl 类中？
任何帮助或示例将不胜感激。
【问题讨论】：
Afaik 你不需要明确配置断言是加密的。而且你最明确地不需要修改任何类。至于你的例外：很明显你不需要绑定来处理传入的消息，这与加密无关。 您可以发布您要发送的消息吗？ 是否有工具可以创建加密断言以测试服务？我目前正在使用 SAMLING (github.com/capriza/samling)，这很棒，但它不支持加密断言。 【参考方案1】：我们通常使用 SAML 工具 (https://www.samltool.com/generic_sso_res.php)，其中包含一些带有加密断言的示例。
对于自动化测试，我们倾向于动态生成 SAML 请求和响应，自己签署 XML，然后在集成测试中将其提供给应用程序。
