Subject: Canonicalization support in the XML Security Suite


Lynda, the documentation for the latest version of the XML Security Suite
(the 10/29/2001 version on www.alphaworks.ibm.com/tech/xmlsecuritysuite)
says that it supports both the January 19, 2000 draft and the March 15,
2001 recommendation.  I'm attaching the documentation for the
Canonicalization piece below.

Let me know if you need anything else, and I'll try to provide "same-day
service" on my response.  My apologies again for not responding earlier.

Thanks,
-Doug

Title: XML Canonicalizer

XML Canonicalizer

The XML Security Suite has classes that canonicalize XML documents. They are based on Canonical XML [19-January-2000], Canonical XML [W3C REC, 15-Mar-20001 and Exclusive XML Canonicalization.

Sample programs

c14n.C14nDOM and c14n.C14nSAX canonicalize an XML document from the stardard input, and output to the standard output.

E:\xss4j\samples> java c14n.C14nDOM -old < foo.xml > foo-canonicalized.xml

E:\xss4j\samples> java c14n.C14nSAX < foo.xml > foo-canonicalized.xml

These programs support [19-January-2000] Canonical XML. c14n.C14nDOM has the "-xpath" option that enables [15-Mar-2001] canonicalization.

E:\xss4j\samples> java c14n.C14nDOM -xpath < foo.xml > foo-canonicalized.xml

c14n.C14nDOM has the "-exclusive" option that enable Exclusive XML Canonicalization.

E:\xss4j\samples> java c14n.C14nDOM -exclusive < foo.xml > foo-canonicalized.xml

c14n.SerialzeSubset is a sample program for canonicalization against Document Subsets. Add xalan.jar of Xalan-2.0 to CLASSPATH, and type as follows:

E:\xss4j\samples> java c14n.SerializeSubset xpath-expression < foo.xml > foo-canonicalized.xml

For Exclusive C14n, specify `-eprefix-list'.

E:\xss4j\samples> java c14n.SerializeSubset -edsig,xhtml xpath-expression < foo.xml > foo-canonicalized.xml
