checkC14NAlgorithm

public static void checkC14NAlgorithm(Algorithm c14n)
                               throws UnsupportedAlgorithmException

Verifies input C14N Algorithm is in fact a C14N Algorithm by querying the default Apache Canonicalizer.

Parameters:

c14n - - A C14N algorithm.

Throws:

UnsupportedAlgorithmException - - If the URI is not registered in the default Canonicalizer.

allTransformsAreC14N

public static boolean allTransformsAreC14N(org.apache.xml.security.signature.Reference r)
                                    throws org.apache.xml.security.exceptions.XMLSecurityException

Checks if all the transforms in a ds:Reference are canonicalization transforms.

Parameters:

r - the reference

Returns:

true if all transforms are c14n, false otherwise.

Throws:

org.apache.xml.security.exceptions.XMLSecurityException
