SSL对等方在Spring SAML中主机名验证失败

Question

我正试图将我的Spring Boot项目配置为对第三方IDP使用SAML身份验证。我已经实现了使vdenotaris中的配置与SSOCycle提供程序一起工作，现在我想将其切换到其他提供程序。

SAML元数据endpoint启用了HTTPS，我已经创建了一个密钥库，其中包含元数据中给出的证书（用于签名和加密）和HTTPendpoint提供的证书（基于此答案）。然后，我将它们保存在证书文件（$CERTIFICATE_FILE）中，并使用此脚本生成我的密钥库：

keytool -delete -alias third-party -keystore $KEYSTORE_FILE -storepass $KEYSTORE_PASSWORD
keytool -import -alias third-party -file $CERTIFICATE_FILE -keystore $KEYSTORE_FILE -storepass $KEYSTORE_PASSWORD -noprompt
keytool -genkeypair -alias mycompany -keypass mycompanypass -keystore $KEYSTORE_FILE

然后，当使用此密钥库检索 SAML 元数据时，我收到以下错误：

org.opensaml.saml2.metadata.provider.MetadataProviderException: org.opensaml.saml2.metadata.provider.MetadataProviderException: Error retrieving metadata from https://third.party.provider/metadata

这些是我的配置的相关部分，基于vdenotaris的链接项目:

// Setup TLS Socket Factory
@Bean
public TLSProtocolConfigurer tlsProtocolConfigurer() {
    return new TLSProtocolConfigurer();
}

@Bean
public ProtocolSocketFactory socketFactory() {
    return new TLSProtocolSocketFactory(keyManager(), null, "allowAll");
}

@Bean
public Protocol socketFactoryProtocol() {
    return new Protocol("https", socketFactory(), 443);
}

@Bean
public MethodInvokingFactoryBean socketFactoryInitialization() {
    MethodInvokingFactoryBean methodInvokingFactoryBean = new MethodInvokingFactoryBean();
    methodInvokingFactoryBean.setTargetClass(Protocol.class);
    methodInvokingFactoryBean.setTargetMethod("registerProtocol");
    Object[] args = { "https", socketFactoryProtocol() };
    methodInvokingFactoryBean.setArguments(args);
    return methodInvokingFactoryBean;
}

// Central storage of cryptographic keys
@Bean
public KeyManager keyManager() {
    DefaultResourceLoader loader = new DefaultResourceLoader();
    Resource storeFile = loader.getResource("classpath:/saml/mySamlKeystore.jks");
    String storePass = "storepass";
    Map<String, String> passwords = new HashMap<String, String>();
    passwords.put("mycompany", "mycompanypass");
    String defaultKey = "mycompany";
    return new JKSKeyManager(storeFile, storePass, passwords, defaultKey);
}

然而，在这里我发现了一些误解。据我所知，TLSProtocolConfigurer本身创建了一个TLSProtocolSocketFactory，为什么示例项目同时创建了这两个bean？根据文档，使用TLSProtocolConfigurer应该足够了，但是如何创建socketFactoryProtocol（）？

如果这里有灯光我会很感激的。

Answer 1

@Bean
    @Qualifier("idp-ssocircle")
    public ExtendedMetadataDelegate ssoCircleExtendedMetadataProvider()
        throws MetadataProviderException {
    String idpSSOCircleMetadataURL = "https://idp.ssocircle.com/idp-meta.xml";
    HTTPMetadataProvider httpMetadataProvider = new HTTPMetadataProvider(
            this.backgroundTaskTimer, httpClient(), idpSSOCircleMetadataURL);
    httpMetadataProvider.setParserPool(parserPool());
    ExtendedMetadataDelegate extendedMetadataDelegate = 
            new ExtendedMetadataDelegate(httpMetadataProvider, extendedMetadata());
    extendedMetadataDelegate.setMetadataTrustCheck(false);
    extendedMetadataDelegate.setMetadataRequireSignature(false);
    backgroundTaskTimer.purge();
    return extendedMetadataDelegate;
}

extendedMetadataDelegate.setMetadataTrustCheck（false）；

Answer 2

我没有为导入的证书文件提供密码：

@Bean
public KeyManager keyManager() {
    DefaultResourceLoader loader = new DefaultResourceLoader();
    Resource storeFile = loader.getResource("classpath:/saml/mySamlKeystore.jks");
    String storePass = "storepass";
    Map<String, String> passwords = new HashMap<String, String>();
    passwords.put("mycompany", "mycompanypass");
    passwords.put("third-party", "mycompanypass");
    String defaultKey = "mycompany";
    return new JKSKeyManager(storeFile, storePass, passwords, defaultKey);
}

这样，应用程序就可以从密钥库读取证书并信任它们，而无需将它们安装在JDK证书库中。

Answer 3

这是我的JKS密钥管理器bean配置。

@Bean
public ProtocolSocketFactory socketFactory() {
return new TLSProtocolSocketFactory(keyManager(), null, "default");
}

@Bean
public KeyManager keyManager() {
DefaultResourceLoader loader = new DefaultResourceLoader();
Resource storeFile = loader.getResource("classpath:/saml/samlKeystore.jks");
String storePass = keyStorePwd;
Map<String, String> passwords = new HashMap<String, String>();
passwords.put(keyStoreAlias, keyStorePwd);
String defaultKey = keyStoreAlias;
return new JKSKeyManager(storeFile, storePass, passwords, defaultKey);

}

看起来 IDP 已更改其公共证书，该证书在我们的本地密钥库 （samlKeystore.jks） 中不可用。我使用OpenSSL命令手动下载了他们的公共证书，并使用keytool实用程序导入了相同的证书。

openssl s_client -showcerts -connect iam-sso.google.net:443 </dev/null 2>/dev/null|openssl x509 -outform PEM >mycertfile.pem

keytool -import -alias "new-public-cert" -keystore /usr/share/tomcat8/webapps/ROOT/WEB-INF/classes/saml/samlKeystore.jks
