Class SAMLObjectContentReference

java.lang.Object

org.opensaml.common.impl.SAMLObjectContentReference

All Implemented Interfaces:

ContentReference

public class SAMLObjectContentReference
extends Object
implements ContentReference

A content reference for SAML objects that will be signed. The reference is created per the SAML specification.

The default digest algorithm used is the value configured in the global security configuration's SecurityConfiguration.getSignatureReferenceDigestMethod(), if available, otherwise it will be SignatureConstants.ALGO_ID_DIGEST_SHA1.

The default set of transforms applied consists of SignatureConstants.TRANSFORM_ENVELOPED_SIGNATURE and SignatureConstants.TRANSFORM_C14N_EXCL_WITH_COMMENTS.

When generating an exclusive canonicalization transform, an inclusive namespace list is generated from the namespaces, retrieved from XMLObject.getNamespaces(), used by the SAML object to be signed and all of it's descendants.

Note that the SAML specification states that: 1) an exclusive canonicalization transform (either with or without comments) SHOULD be used. 2) transforms other than enveloped signature and one of the two exclusive canonicalizations SHOULD NOT be used. Careful consideration should be made before deviating from these recommendations.
