Java 如何使用spring-security-saml2配置服务提供商以使用EncryptedAssertions？

我使用这个优秀的repo作为指导，并尝试将其设置为验证和解密包含

encryptedsassertion

的传入SAML消息

idP元数据在XML中定义签名和加密密钥。这是在服务提供商中设置的

@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;
}

我在这里读到，您可以配置idp使用的签名和加密密钥，以便对断言进行解密（至少我假设是这样）

这是让服务使用

encryptedsassertion

s的正确方法吗？我一直在寻找这个无效的消息墙，并没有找到一个明确描述如何处理这个问题的可靠的教程或文档。还不确定解决方案是否存在于我必须修改的

websoprofileconsumeripl

类中

---

我们通常使用SAML工具（），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，自己对XML进行签名，然后在集成测试中将其提供给应用程序。

Afaik您不需要显式地配置已加密的断言。而且您完全不需要修改任何类。至于您的例外情况：很明显，您不需要绑定来处理传入消息，这与enrcyption无关。您可以发布您试图发送的消息吗？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（），这很好，但它不支持加密断言。
