Encryption/signing of multiple message parts with same name not working
-----------------------------------------------------------------------
Key: WSS-254
URL: https://issues.apache.org/jira/browse/WSS-254
Project: WSS4J
Issue Type: Bug
Components: WSS4J Core
Affects Versions: 1.5.9, 1.5.8, 1.5.7, 1.5.6, 1.5.5, 1.5.4, 1.5.10, 1.6
Environment: all. (found out an a windows vista machine with java 1.6)
Reporter: Marcin Markiewicz
Assignee: Colm O hEigeartaigh
Priority: Critical
The current implementation of the class "WSSecEncypt" lookf in the document to
encrypt for elements only by their name and namespace (this are the only
informations provided by the class "WSEncryptionPart"). The search find the
first element with this name and lets encrypt it. If there are other elements
with the same name we wish to encrypt it cannot be done. But it is needed if
one uses lists of elements
Following example shows the issue:
<xml...>
<soapenv:Envelope>
<soapenv:Header>
<myNS:Header1>
<!-- XML data-->
</myNS:Header1>
<myNS:Header2>
<!-- XML data-->
<myNS:attachment>
<!-- some data we don't wish to encrypt -->
<myNS:attachment>
</myNS:Header2>
...
<myNS:Attachments>
<myNS:attachment>
<!-- 1. binary data base64 encoded -->
</myNS:attachment>
<myNS:attachment>
<!-- 2. binary data base64 encoded -->
</myNS:attachment>
<myNS:attachment>
<!-- 3. binary data base64 encoded -->
</myNS:attachment>
...
</myNS:Attachments>
...
<myNS:HeaderX>
<!-- XML data-->
</myNS:HeaderX>
</soapenv:Header>
<soapenv:Body>
<!-- XML data-->
</soapenv:Body>
</soapenv:Envelope>
if we use the WSEncyrpionPart this way:
WSEncryptionPart encryptionPart = new WSEncryptionPart("attachment",
"myNS-URI", "Content");
then only the element "Envelope/Header/Header2/attachment" will be encryptet.
Thus the one we don't want to encrypt, but the other ones will not be encrypted.
To solve this problem a XPath support in WSEncryptionPart and WSSecEncryption
is to be implemented (and maybe more...)
