Gene B. commented on WSS-508:
-----------------------------
Marc: I am looking at the DOMXMLSignature class and its easier for me to
understand your explanation now. Signature value validation is solely based on
the SignedInfo element digest, and is independent of references validation and
precedes the latter. It seems redundant though that signature value is a
function of SignedInfo, and SignedInfo is a derivative of all signed parts. And
yet the code has to validate the signature first, and then still go over all
the references. I guess it is more of a conceptual problem - but understanding
this process is not for the faint of heart :)
> When using "add inclusive prefixes" and EXC C14N - signature cannot be
> validated

> Key: WSS-508
> URL: https://issues.apache.org/jira/browse/WSS-508
> Project: WSS4J
> Issue Type: Bug
> Components: WSS4J Core
> Affects Versions: 2.0.0, 2.0.1
> Environment: WAS 7.x, IBM JDK 1.6, WebSphere JAX-WS stack, MS Windows.
> Reporter: Gene B.
> Assignee: Colm O hEigeartaigh
> Attachments: log 01 - signature verification failed with
> InclusiveNamespaces PrefixList.txt, log 02 - signature verification ok -
> signed by SOAP UI.txt, log_03a - consumer - sign message use
> InclusiveNamespaces prefix list.txt, log_03b - provider - signature
> verification failed.txt, request1-printedby-provider-signedby-soapui.xml,
> request1-printedby-provider-signedby-wss4j.xml
>
>
> Security implemented using WSS4J securement/validation action approach. We
> are trying to sign the body.
> The provider is a JAX-WS service running on WebSphere JAX-WS stack. Custom
> handler uses WSS4j to validate security.
> The consumer is a WebSphere JAX-WS dispatch client – also attaching custom
> security handler.
> Signature can be validated on the provider side when EXC C14N
> canonicalization is specified with BST compliance flag relaxed. That is
> because when we chose to add “InclusiveNamespaces” “PrefixList” on the
> consumer side, verification fails. When the same test is done with the SOAP
> UI – signature verifies Ok – so I am blaming the consumer – the signing
> process - not verification process.
> I am attaching a log file which shows verification failure when the
> InclusiveNamespaces option is used. If not for this option – this
> verification would’ve been a success.
