Encryption with AES256

[Garzon Maldonado, Jesus Javier]

Hello all,

 

I'm using wss4j 1.0 (all sources updated from CVS), JDK 1.5.0, JBoss 3.2.6 and Windows XP.

 

I've successfully configured WSDoAllSender and WSdoAllReceiver to sign and encrypt SOAP messages. However, when I try to apply AES algorithm with 256 bits key length it throws the following exception:

 

org.apache.xml.security.encryption.XMLEncryptionException: Illegal key size or default parameters
Original Exception was java.security.InvalidKeyException: Illegal key size or default parameters
at org.apache.xml.security.encryption.XMLCipher.encryptData(Unknown Source)

at org.apache.ws.axis.security.WSDoAllSender.performENCRAction(WSDoAllSender.java:453) [...]

 

It seems to be a key initialization problem, what should I do to solve it?.

 

Bellow you can find handler's definition in client-config.wsdd:

<handler name="DoSecuritySender" type="java:org.apache.ws.axis.security.WSDoAllSender" >

<parameter name="user" value="wssecurity"/>

<parameter name="passwordCallbackClass" value="my_package.CPWCallback"/>

<parameter name="action" value="Encrypt Signature"/>

<parameter name="signaturePropFile" value="WEB-INF/wssecurity.properties" />

<parameter name="encryptionSymAlgorithm" value="http://www.w3.org/2001/04/xmlenc#aes256-cbc" />

<parameter name="encryptionParts"

value="{Content}{http://bpc2/xml/schemas/MensajeAFU_FUS}MSGID" />

<parameter name="signatureKeyIdentifier" value="DirectReference" />

<parameter name="encryptionKeyIdentifier" value="X509KeyIdentifier" />

</handler>

Thank you very much.

 

Best regards.
