----------------------------------

             Summary: CAs with the NameConstraint extension cause exceptions when \
verifying trust  Key: WSS-611
                 URL: https://issues.apache.org/jira/browse/WSS-611
             Project: WSS4J
          Issue Type: Bug
          Components: WSS4J Core
    Affects Versions: 2.1.10
            Reporter: Richard Porter
            Assignee: Colm O hEigeartaigh
             Fix For: 2.2.0


When a CA with NameConstraints is in the truststore, it causes a failure with any \
crypto Cert provider. The underlying cause is an {{IllegalArgumentException}} thrown \
because the Sequence data has been encoded as an Octet String and it is not being \
correctly decoded.

While the relevant RFCs are a bit ambiguous with regard to extensions and whether \
they are all encoded as Octet Strings or not, the documentation on Java's \
implementation of [X509Extension|https://docs.oracle.com/javase/8/docs/api/java/security/cert/X509Extension.html#getExtensionValue-java.lang.String-] \
are unambiguous: it will be a "DER-encoded OCTET string for the extension value.

Beneath this issue lies another, the fact that the Sun default implementation of PKIX \
path validation does not support TrustAnchors with NameConstraints attached. So \
fixing the first issue also requires conditionally constructing TrustAnchors with \
NameConstraints or with null.
