             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.
