---------------------------------------
Summary: Incorrect Symmetric Key Derivation Length validation
Key: WSS-472
URL: https://issues.apache.org/jira/browse/WSS-472
Project: WSS4J
Issue Type: Bug
Reporter: Colm O hEigeartaigh
Assignee: Marc Giger
Fix For: 2.0
There is an error in validating Signature Key Lengths against policy when
derived keys are used with the Symmetric binding. For the "Basic256" policy for
example, symmetric key lengths must be 256 bits, but derived keys for signature
purposes can be 192 bits. The problem is that the SignatureVerifier class in
Santuario asks for a secret key using XMLSecurityConstants.Sym_Sig, and
eventually AbstractInboundSecurityToken ends up creating a new
AlgorithmSuiteSecurityEvent using this. We need some way to distinguish between
the two cases for validating against the AlgorithmSuite policy.
