[原创]实施WebService Security[WS-Security1.0]的Encrypt和Sign模式(XFire+WSS4J)

阅读更多

鉴于很多系统需要实施WS-Security的标准，我们在SpringSide中提供了XFire+WSS4J的Demo，本文介绍SpringSide中Spring+XFire+WSS4J的基本配置

[WebService Server端配置]
第一，创建一个基本的BookService

public   interface  BookService  {
    /** *//**
     * 按书名模糊查询图书
     */
    List findBooksByName(String name);

    /** *//**
     * 查找目录下的所有图书
     *
     * @param categoryId 如果category为null或“all”， 列出所有图书。
     */
    List findBooksByCategory(String categoryId);

    /** *//**
     * 列出所有分类.
     *
     * @return List，或是null。
     */
    List getAllCategorys();
}

第二，接口扩展，即Extend基本的BookService，在XFire中，不同的WSS4J策略需要针对不同的ServiceClass，否则里面的定义会Overlap。

public   interface  BookServiceWSS4JEnc   extends  BookService  {

}

public   interface  BookServiceWSS4JSign   extends  BookService  {

}

第三，配置Spring的ApplicationContext文件

    
     < bean  id ="baseWebService"  class ="org.codehaus.xfire.spring.remoting.XFireExporter"  abstract ="true" >
         < property  name ="serviceFactory"  ref ="xfire.serviceFactory" />
         < property  name ="xfire"  ref ="xfire" />
     bean >

     < bean  class ="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping" >
         < property  name ="mappings" >
             < value >
                /BookService=bookService
                /BookServiceWSS4J=bookServiceWSS4J
                /BookServiceWSS4JEnc=bookServiceWSS4JEnc
                /BookServiceWSS4JSign=bookServiceWSS4JSign
             value >
         property >
     bean >

                 < ref  bean ="wss4jInHandler" />
                 < ref  bean ="validateUserTokenHandler" />
             list >
         property >
     bean >

     < bean  id ="domInHandler"  class ="org.codehaus.xfire.util.dom.DOMInHandler" />

     < bean  id ="wss4jInHandler"  class ="org.codehaus.xfire.security.wss4j.WSS4JInHandler" >
         < property  name ="properties" >
             < props >
                 < prop  key ="action" > UsernameToken prop >

         < property  name ="serviceClass"  value ="org.springside.bookstore.plugins.xfire.service.BookServiceWSS4JEnc" />
         < property  name ="inHandlers" >
             < list >
                 < ref  bean ="domInHandler" />
                 < ref  bean ="wss4jInHandlerEnc" />
                 < ref  bean ="validateUserTokenHandler" />
             list >
         property >
     bean >
        
     < bean  id ="wss4jInHandlerEnc"  class ="org.codehaus.xfire.security.wss4j.WSS4JInHandler" >

         < property  name ="serviceBean"  ref ="bookManager" />
         < property  name ="serviceClass"  value ="org.springside.bookstore.plugins.xfire.service.BookServiceWSS4JSign" />
         < property  name ="inHandlers" >
             < list >
                 < ref  bean ="domInHandler" />

             < prop  key ="passwordCallbackClass" > org.springside.bookstore.plugins.xfire.wss4j.PasswordHandler prop >
           props >
         property >
     bean >

第四，配置insecurity_enc.properties和insecurity_sign.properties两个密钥库配置文件
insecurity_enc.properties：

org.apache.ws.security.crypto.provider = org.apache.ws.security.components.crypto.Merlin
org.apache.ws.security.crypto.merlin.keystore.type = jks
org.apache.ws.security.crypto.merlin.keystore.password = SpringSide
org.apache.ws.security.crypto.merlin.alias.password = SpringSide
org.apache.ws.security.crypto.merlin.keystore.alias = david
org.apache.ws.security.crypto.merlin.file = org/springside/bookstore/plugins/xfire/wss4j/springside_private.jks

outsecurity_sign.properties：

org.apache.ws.security.crypto.provider = org.apache.ws.security.components.crypto.Merlin
org.apache.ws.security.crypto.merlin.keystore.type = jks
org.apache.ws.security.crypto.merlin.keystore.password = SpringSide
org.apache.ws.security.crypto.merlin.keystore.alias = david
org.apache.ws.security.crypto.merlin.file = org/springside/bookstore/plugins/xfire/wss4j/springside_public.jks

第五，使用SecureX生成了两个keystore文件
springside_private.jks

别名名称： david
创建日期：  2006 - 8 - 6
输入类型：KeyEntry
认证链长度：  1
认证  [ 1 ] :

springside_public.jks

         MD5：  CF: 97 : 13 :0C: 70 :D0:4D:B6:B4: 27 :0F:1A:0B:CF:D9:F2
         SHA1： 8E:8E:E8:BC: 64 : 39 :C8: 43 :E4:F7:1B:3B:CE: 48 :1D:6B:A0:2B: 58 :B5

第五，新版本SpringSide需要
http://www.bouncycastle.org/download/bcprov-jdk15-133.jar
并且要配置java.security
另外,还要使用jdk加密增强策略
http://www.blogjava.net/openssl/archive/2006/03/08/34381.html

用户要使用WSS4J，需要配置Bouncycastle这个SecurityProvider，否则
运行Enc模式的XFire认证的时候，会抛出异常：
org.apache.ws.security.WSSecurityException: An unsupported signature or encryption algorithm was used unsupported key
配合java.security也是非常简单:
在最后加入BouncycastleProvider。
security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.net.ssl.internal.ssl.Provider
security.provider.3=com.sun.rsajca.Provider
security.provider.4=com.sun.crypto.provider.SunJCE
security.provider.5=sun.security.jgss.SunProvider
security.provider.6=org.bouncycastle.jce.provider.BouncyCastleProvider

[WebService Client端配置]
1，Encrypt模式的Client是在客户端用david的公钥加密Soap里面的usernameToken，然后发送到Web服务，Web服务用david的私钥来验证。这种模式需要客户端预先知道服务器端的公钥。

在Encrypt模式中，需要这样配置ClientHandler：

        Service serviceModel  =   new  ObjectServiceFactory().create(BookServiceWSS4JEnc. class );
        XFireProxyFactory factory  =   new  XFireProxyFactory(getXFire());

        BookService service  =  (BookService) factory.create(serviceModel,  " xfire.local://BookServiceWSS4JEnc " );

        Client client  =  ((XFireProxy) Proxy.getInvocationHandler(service)).getClient();
         // 挂上WSS4JOutHandler，提供认证
        client.addOutHandler( new  DOMOutHandler());
        Properties properties  =   new  Properties();
        configureOutProperties(properties);
        client.addOutHandler( new  WSS4JOutHandler(properties));

        List list  =  service.getAllCategorys();

configureOutProperties函数负责指定Client使用何种安全策略，没错，使用outsecurity_enc.properties，这个properties是跟Server端的insecurity_enc.properties一起使用的。

     protected   void  configureOutProperties(Properties config) {
        config.setProperty(WSHandlerConstants.ACTION, WSHandlerConstants.ENCRYPT);
        config.setProperty(WSHandlerConstants.USER,  " david " );
         // config.setProperty(WSHandlerConstants.PW_CALLBACK_CLASS, PasswordHandler.class.getName());
         // Configuration of public key used to encrypt message goes to properties file.
        config.setProperty(WSHandlerConstants.ENC_PROP_FILE,
                                " org/springside/bookstore/plugins/xfire/outsecurity_enc.properties " );
    }

outsecurity_enc.properties：

org.apache.ws.security.crypto.provider = org.apache.ws.security.components.crypto.Merlin
org.apache.ws.security.crypto.merlin.keystore.type = jks
org.apache.ws.security.crypto.merlin.keystore.password = SpringSide
org.apache.ws.security.crypto.merlin.keystore.alias = david
org.apache.ws.security.crypto.merlin.file = org/springside/bookstore/plugins/xfire/wss4j/springside_public.jks

2, Sign模式的Client同样也是很简单，这种模式是Client端用自己的私钥为usernameToken签名，服务器端用Client的公钥来验证签名，因此，服务器端需要预先知道客户端的公钥。
对应于Encrypt模式，这里的configureOutProperties需要这样来配置：

     protected   void  configureOutProperties(Properties properties) {
        properties.setProperty(WSHandlerConstants.ACTION,WSHandlerConstants.SIGNATURE);
         //  User in keystore
        properties.setProperty(WSHandlerConstants.USER,  " david " );
         //  This callback is used to specify password for given user for keystore
        properties.setProperty(WSHandlerConstants.PW_CALLBACK_CLASS, PasswordHandler. class .getName());
         //  Configuration for accessing private key in keystore
        properties.setProperty(WSHandlerConstants.SIG_PROP_FILE, " org/springside/bookstore/plugins/xfire/outsecurity_sign.properties " );
        properties.setProperty(WSHandlerConstants.SIG_KEY_ID, " IssuerSerial " );
    }

outsecurity_sign.properties：

org.apache.ws.security.crypto.provider = org.apache.ws.security.components.crypto.Merlin
org.apache.ws.security.crypto.merlin.keystore.type = jks
org.apache.ws.security.crypto.merlin.keystore.password =
