使用自定义X509KeyManager时,Java无法为SSL握手确定匹配的密码套件

标签: java ssl soap jax-ws

我正在使用Java7和JAX-WS 2.2。

对于SOAP Web服务,我需要创建一个自定义X509KeyManager,以便为JKS密钥库中的每个连接客户端找到正确的证书。

但是,我已经在努力让我的自定义密钥管理器运行了。到目前为止,我使用默认的(从初始化的KeyManagerFactory检索),它基本上有效 - 但当然它没有选择正确的证书。所以第一个想法是创建一个自定义X509KeyManager,它保存原始密钥管理器,只写出一些日志消息,但通常使用默认行为。

由于某种原因根本不起作用。无法建立SSL握手。在 ClientHello 之后,日志显示以下错误:

据我所知,我根本没有删除任何密码套件!并且SSL握手可以使用相同的证书。

这是我的主要经理:

public class CustomX509KeyManager extends X509ExtendedKeyManager
{
   private static final Logger LOG = Logger.getLogger( CustomX509KeyManager.class );
   private final X509KeyManager originalKeyManager;

   public CustomX509KeyManager(final X509KeyManager keyManager)
   {
      super();
      this.originalKeyManager = keyManager;
   }

   @Override
   public String chooseServerAlias(final String keyType, final Principal[] issuers,
     final Socket socket)
   {
      final String serverAliases=
            this.originalKeyManager.chooseServerAlias( keyType, issuers, socket );
      CustomX509KeyManager.LOG.info( "chooseServerAlias() " + serverAliases );
      return serverAliases;
   }

   ...
}

其他方法(此处未显示)也只是调用originalKeyManager中的相应方法。在测试期间,我从未看到chooseServerAlias()方法的日志消息。

它是从getSslContext()方法中的另一个类初始化的:

private KeyManager[] getKeyManagers(final KeyManagerFactory keyManagerFactory)
{
   final KeyManager[] keyManagers = keyManagerFactory.getKeyManagers();

   // replace any X509KeyManager with our own implementation
   for ( int i = 0; i < keyManagers.length; i++ )
   {
      if ( keyManagers[i] instanceof X509KeyManager )
      {
         keyManagers[i] =
               new CustomX509KeyManager( ( X509KeyManager ) keyManagers[i] );
      }
   }

   return keyManagers;
}

public SSLContext getSslContext()
{
  // create the KeyStore and load the JKS file
  final KeyStore keyStore = createKeyStore();

  // initialize key and trust manager factory
  final KeyManagerFactory keyManagerFactory =
        KeyManagerFactory.getInstance( KeyManagerFactory.getDefaultAlgorithm() );
  keyManagerFactory.init( keyStore, "changeit".toCharArray() );
  final TrustManagerFactory trustManagerFactory =
        TrustManagerFactory.getInstance( TrustManagerFactory.getDefaultAlgorithm() );
  trustManagerFactory.init( keyStore );

  // initialize the SSL context
  final SSLContext sslContext = SSLContext.getInstance( "TLS" );
  // sslContext.init( keyManagerFactory.getKeyManagers(),
  //      trustManagerFactory.getTrustManagers(), new SecureRandom() );
  sslContext.init( getKeyManagers( keyManagerFactory ),
        trustManagerFactory.getTrustManagers(), new SecureRandom() );
  return sslContext;
}

注释行显示默认密钥管理器的原始用法。

知道什么是错的吗?为什么使用我的CustomX509KeyManager与默认密钥管理器不同的行为无法完成握手?使用默认密钥管理器,将为TLS_DHE_RSA_WITH_AES_128_CBC_SHA算法协商加密,该算法也可以与自定义密钥管理器一起使用,但由于某些原因未选择。

更新1

我正在尝试以客户端模式将openssl连接到服务器,但服务器使用SSL遇到相同的问题。当我使用TLS协议时,会出现其他错误消息

  

不支持的扩展名type_35,数据:

出现

更新2

我可以确认上述关于不受支持的扩展的通知也会在成功握手时出现,因此这是一个错误的痕迹。

2 个答案:

答案 0 :(得分:3)

经过几天的试用和错误我终于找到了我的错误!

在Java 7中,自定义密钥管理器应扩展X509ExtendedKeyManager,这会强制您实现接口X509KeyManager的五种方法。但是,类X509ExtendedKeyManager中还有两个方法未声明为抽象,但必须才能被覆盖以便正确使用:

  • chooseEngineClientAlias(String[], Principal[], SSLEngine)
  • chooseEngineServerAlias(String, Principal[], SSLEngine)

通过将调用委托给我的originalKeyManager(其类型为X509ExtendedKeyManager)覆盖并实现方法后,SSL握手终于成功了。

答案 1 :(得分:0)

您似乎没有在代码段中的任何位置读取密钥文件。这就是SSL_NULL_WITH_NULL_NULL的原因。我建议你实现X509KeyManager并在构造函数中读取文件,因此可以用letter来选择合适的密钥。这一行(不是为简短回答而描述的所有必需方法):

public class CustomX509KeyManager implements X509KeyManager
{
   private final KeyStore keyStore;
   private final String alias;
   private final char[] password;

   public CustomX509KeyManager(final String keyStoreFile, final char[] password, final String alias)
    throws IOException, GeneralSecurityException
   {
       this.alias = alias;
       this.password = password;
       synchronized(keyStoreFile)
       {
          InputStream stream = new FileInputStream(keyStoreFile);
          keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
          keyStore.load(stream, password);
          stream.close();
       }
   }

   @Override
   public PrivateKey getPrivateKey(String alias)
   {
       try {
           return (PrivateKey) keyStore.getKey(alias, password);
       } catch (Exception e) {
            e.printStackTrace();
            return null;
       }
    }

    @Override
    public X509Certificate[] getCertificateChain(String alias)
    {
        try {
            java.security.cert.Certificate[] certs = keyStore.getCertificateChain(alias);
            if (certs == null || certs.length == 0)
                return null;
            X509Certificate[] x509 = new X509Certificate[certs.length];
            for (int i = 0; i < certs.length; i++)
                x509[i] = (X509Certificate)certs[i];
            return x509;
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }          
    }

}

然后像

一样使用它
sslContext.init(new X509KeyManager[] { 
                    new CustomX509KeyManager(keyStoreFile, 
                        keyStorePass.toCharArray(), alias) }, null, null);
