Spring WS Security on both client and server

Recently, I have been playing with Spring WS with WS-Security. I just want to write down how it works. Do not except anything special, just simple example of basic security operations.

The example

We want to implement both client and server side. The client will sign the message, encrypt some part of it and add a timestamp. To make it more complex and real-life like we will sign the message using private key with alias “client” and encrypt the message using public key called “server”. Server will validate that the request is valid and will just sign the response using his key called “server”. Please note that I have picked Wss4j implementation because the configuration seemed to be easier than Xws.

Client

It’s easy to do configure client interceptor like this.

<bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
	<property name="interceptors">
		<list>
			<ref local="wsClientSecurityInterceptor"/>
		</list>
	</property>
	...
</bean>

<bean id="wsClientSecurityInterceptor"
	class="org.springframework.ws.soap.security.wss4j.Wss4jSecurityInterceptor">
	<property name="securementActions" value="Timestamp Signature Encrypt" />
	<!-- Key alias for signature -->
	<property name="securementUsername" value="client" />
	<property name="securementPassword" value="" />
	<property name="securementSignatureCrypto" ref="clientCrypto"/>
	<property name="securementEncryptionCrypto" ref="clientCrypto"/>
	<property name="securementEncryptionParts" value="{Content}{http://javacrumbs.net/calc}a"/>
	<!-- Key alias for encryption -->
	<property name="securementEncryptionUser" value="server"/>
	
	<!-- Validation config -->
	<property name="validationActions" value="Signature" />
	<property name="validationSignatureCrypto" ref="clientCrypto"/>
</bean>

<bean id="clientCrypto" class="org.springframework.ws.soap.security.wss4j.support.CryptoFactoryBean">
    <property name="keyStorePassword" value="mypasswd"/>
    <property name="keyStoreLocation" value="classpath:security/client-keystore.jks"/>
</bean>

As you can see, there is nothing special. We just define which actions to take and properties. The only confusing part is, that key alias is defined as “securementUsername”.

Whit this configuration we will get following SOAP message.

Server config

To configure server, you have to define Spring WS server interceptor like this (full example).

<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping">
	<property name="interceptors">
		<list>
			<ref local="wsServerSecurityInterceptor" />
		</list>
	</property>
</bean>

<bean id="wsServerSecurityInterceptor"	class="org.springframework.ws.soap.security.wss4j.Wss4jSecurityInterceptor">
	<!-- Validation part -->
	<property name="validationActions" value="Timestamp Signature Encrypt"/>
	<property name="validationSignatureCrypto" ref="serverCrypto"/>
	<property name="validationDecryptionCrypto" ref="serverCrypto"/>
	<property name="validationCallbackHandler">
		<bean class="org.springframework.ws.soap.security.wss4j.callback.KeyStoreCallbackHandler">
			<property name="keyStore">
				<bean class="org.springframework.ws.soap.security.support.KeyStoreFactoryBean">
				    <property name="password" value="mypasswd"/>
				</bean>
			</property>
			<property name="privateKeyPassword" value=""/>
		</bean> 
	</property>
	<!-- Sign the response -->
	<property name="securementActions" value="Signature" />
	<property name="securementUsername" value="server" />
	<property name="securementPassword" value="" />
	<property name="securementSignatureCrypto" ref="serverCrypto"/>
</bean>

<bean id="serverCrypto" class="org.springframework.ws.soap.security.wss4j.support.CryptoFactoryBean">
    <property name="keyStorePassword" value="mypasswd"/>
    <property name="keyStoreLocation" value="classpath:security/server-keystore.jks"/>
</bean>

No surprise here neither. The response will look like this.
